Pit and fissure sealants in pediatric dentistry. SRM J Res
Dent Sci 2014;5:253-7.
 Dental caries remains as one of the most
widespread disease of mankind.
 It is the single most common chronic childhood
disease.
 Caries in children begins shortly after eruption of
the deciduous teeth and continue to increase at a
remarkable rate in their school age.
 Deep pits and fissures favor food retention and are
difficult to clean by routine brushing.
 It provides a favorable environment for the oral
microorganisms to thrive and convert the
carbohydrates to acids, leading to demineralization
of the enamel.
Muthu MS, Sivakumar N. Pediatric dentistry. Principles and
Practice.1st ed. New Delhi: Elsevier; 2009.
 The most efficient way to prevent pit and fissure
caries is by effectively sealing the fissures using
resins called pit and fissure sealants.
 There have been many attempts made within past
decades to prevent the development of caries, in
particular occlusal caries as it was once generally
accepted that pits and fissures of teeth would
become infected with bacteria within 10 years of
erupting into the mouth .

Bowen in 1965 reported BIS-GMA material development.
 BIS-GMA resin is the reaction product of bisphenol
A and glycidylmetharylate.
 It is the base resin to most of the current
commercial resin.
 Urethane dimethacrylate and other dimethacrylates
resins are also used in the sealant materials.
Based on filler content
 Sealants are classified into filled and unfilled resin
systems in regard to the presence or absence of
filler particles in the system, but most of the self-
cured resins are unfilled.
Kervanto-Seppälä S, Pietilä I, Meurman JH, Kerosuo E. Pit and
fissure sealants in dental public health — Application criteria
And general policy in Finland. BMC Oral Health 2009;9:5.
 The filled sealants contain microscopic
glass beads, quartz particles, and other
fillers used in composites resins.
 The fillers are coated with products such as
silane, to facilitate their combination with
the bisphenol A and glycidyl methacrylate
(BIS-GMA) resin.
The fillers make the resin more resistant to abrasion
and wear.
In contrast, unfilled sealants wear quicker, but
usually do not need occlusal adjustment.
Unfilled resins will penetrate deeper into the fissure
system, and therefore perhaps be better retained.
 Filled resins have shown to be effective in
caries prevention.
Brown MR, Foreman FJ, Burgess JO, Summitt JB. Penetration of
gel and solution etchants in occlusal fissures. ASDC J Dent Child
1988;55:265-8.
 Filled resins are opaque and are available in
tooth-colored or white shades.
 Unfilled resins are color less or tinted
transparent materials.

 They can be CLEAR or TINTED
 In March 1977, the first colored sealant (3M™
ESPE™Concise™ White Sealant) was introduced to
the US market.

children. Pediatr Dent 2002;24:480-8.
 These sealants are easily visible and chair side time
is saved at follow-up.
 Furthermore, parents are reassured when they can
see the sealants on their child’s teeth.
 As the sealant is clearly visible to the child, it is of
benefit to encourage the child to look periodically
for any sealant loss.
 This constant reminder of the presence of a
preventive agent will help in the motivational
aspects of preventive program.

Dent J 1999;186:569-75.
 Tinted and opaque fissure sealants have the
advantage of more accurate evaluation by the
dentist at recall.
 In 2001, dental manufacturers have introduced
sealants that change colour during polymerization.
 The Helioseal Clear Chroma Ivoclar Vivadent AG
changes from clear to green after photo —
polymerization.
 The 3M™ ESPE™ Clinpro™ Sealanth as a pink color
when applied and converts to a white opaque mass
after light curing.

4. Fourth generation
 The first sealant material that utilized the acid etch
technique was introduced in the mid 1960’s and
was a cyanoacrylate (CA) substance.
Pinkham J, Casamassimo P. Pediatric Dentistry. Infancy through
Adolescence. 4th ed. New Delhi: Saunders; 2005.
 CAs were activated with an ultraviolet light source
at a wavelength of 365 nm. Nuva Seal® was the
first successful commercial sealant in market, in
1972.
Donly KJ, García-Godoy F. The use of resin-based composite in
children. Pediatr Dent 2002;24:480-8.
 CAs were not suitable as sealant material owing to
bacterial degradation of the material in the oral
cavity overtime.
 To overcome these CAs were replaced with second
generation sealant materials, which were found to
be resistant to degradation and produced a
tenacious bond with etched enamel.
Pinkham J, Casamassimo P. Pediatric Dentistry. Infancy through
Adolescence. 4th ed. New Delhi: Saunders; 2005.
Cyanoacrylates were first described in 1949 and their
potential as adhesives was quickly recognized.
Various homologues of CA adhesive have been
studied and used, including methyl-, ethyl-,
isobutyl-, isohexyl-, and octyl-CA.
Its clinical applications in dentistry and medicine,
specially as tissue adhesives and sealing materials.
CA adhesive is a compound synthesized by
condensation of a cyanoacetate with formaldehyde in
the presence of a catalyst.
Lesser D. An overview of dental sealants. J Public Health Dent
2001;91/7:1-8.
In preventive dentistry, CA was also the first
material modified for use as a pit and fissure
sealant to help prevent dental decay, especially
on the occlusal surface.
However, because this material biodegrades
and does not last long in the oral cavity, it was
later replaced with other dental materials, such
as GMA dimethacrylate.
Pinkham J, Casamassimo P. Pediatric Dentistry. Infancy through
Adolescence. 4th ed. New Delhi: Saunders; 2005.
 The second generation sealants are the
dimethacrylates, which represent the reaction
product of BIS-GMA ,which is considered by its
originator to be a hybrid between a methacrylate
and an epoxy resin.
 Second generation sealants are auto polymerizing
and set upon mixing with a
chemical catalyst — accelerator system.
They are generally “self-cured” or “chemically cured”
without the need of an external ultraviolet source.
Pinkham J, Casamassimo P. Pediatric Dentistry. Infancy through
Adolescence. 4th ed. New Delhi: Saunders; 2005.
Most commercial sealants available today are BIS-
GMA dimethacrylates or urethane dimethacrylates based
products.
Donly KJ, García-Godoy F. The use of resin-based composite in
children. Pediatr Dent 2002;24:480-8.
Auto polymerizing resins generally performed better
than the early ultraviolet light initiated resin
sealants.

Ripa (1985) reviewed the results of >5 dozen clinical
studies on the effectiveness of first generation
(ultraviolet — initiated) and second generation
(chemically initiated) sealants.
The sealants were evaluated from 1 to 7 years after
placement, second generation sealants provided
superior retention and caries protection than the
first generation sealants.
L.W. Ripa. Sealants Revisited: An Update of the Effectiveness of
Pit and Fissure Sealants. Caries Research 1993;27:77-82.
 The third generation sealants are photo activated
resins which contain a diketone initiator such as
Camphoroquinone and a reducing agent such as
tertiary amine to initiate polymerization.
Use of visible light source requires eye protection
due to the intensity of the light created.
Pinkham J, Casamassimo P. Pediatric Dentistry. Infancy through
Adolescence. 4th ed. New Delhi: Saunders; 2005.
The evaluation of third-generation or visible light
activated sealants falls into the present era of
clinical testing in which retention, rather than
caries inhibition, constitutes the principle criterion
of success.
Retention of sealant material is the main
determinant for the caries preventive effect of
sealant.
L.W. Ripa. Sealants Revisited: An Update of the Effectiveness of
Pit and Fissure Sealants. Caries Research 1993;27:77-82.
A study was conducted to compare the retention of
autopolymerized and light polymerized Delton
fissure sealants in 207 sealed tooth for 5 years
showed that, there was 59% complete retention of
auto polymerized sealants and 48% of the light
polymerized sealants at the end of the study
period.

Fluoride the pivot of preventive dentistry continues
to be the cornerstone of caries prevention
programs.
In order to maximize the exposure time of fluoride
on enamel for improved prevention of dental caries,
fluoride-releasing materials have been developed.
Asmussen E. Clinical relevance of physical, chemical,
and bonding properties of composite resins. Oper
Dent 1985; 10:61-73.
The literature has reported a decrease in enamel
solubility and secondary caries on treatment with
fluoride dental materials based on the fact that
increased fluoride uptake by adjacent enamel
prevents demineralization and promotes
mineralization.

in the epidemiology of dental caries on guidelines
for the use of dental sealants. J Public Health Dent
1995;55:274-91.
 Early in the development of sealants, it was
recognized that the addition of fluoride to a
sealant, or perhaps to the enamel prior to sealant
application, could have the potential benefit of
additional caries protection.
Donly KJ, García-Godoy F. The use of resin-based composite in
children. Pediatr Dent 2002;24:480-8.
 Brown and Selwitz was the first to formulate a
polyurethane fluoride containing sealant material
that would release fluoride on the enamel surface
for an extended period of 24 h to 30 days.
Cohen L, Sheiham A. Importance of variables affecting pit and
fissure sealant use in the United Kingdom. Community Dent
Oral Epidemiol 1988;16:317-20.
 Two methods of fluoride incorporation into pit and
fissure sealants are used. In first method, fluoride
is added to unpolymerized resin in the form of a
soluble fluoride salt.
 After the sealant is applied to the tooth, salt
dissolves and fluoride ions are released, Helioseal-
F is produced based on this procedure.
 The second method of incorporating fluoride is by
addition of an organic fluoride compound that is
chemically bound to the resin to form an ion
exchange resin; Teethmate F-1 is based on this
method.

epidemiology of dental caries on guidelines for the use of
Dental sealants. J Public Health Dent 1995;55:274-91.
 More recently, a commercially available sealant
with fluoride was marketed that purportedly
releases fluoride (fluoroshield).
 Fluoride releasing sealants have shown
antibacterial properties as well as greater
resistance to artificial caries in comparison to
nonfluoridated sealants.
Asmussen E. Clinical relevance of physical, chemical, and
Bonding properties of composite resins. Oper Dent 1985;

 The glass ionomer cement (GIC) developed by
McLean and Wilson in 1960’s have been indicated
as restorative materials, bases and cementing
agents.
 It is also used as sealing agents for pits and
fissures, due to their improved properties such as:
Siegal M. Promotion and use of pit and fissure sealants: An
introduction to the special issue. J Public Health Dent 1995;
55:259-60.
 1. Hydrophilic properties and good adhesion to
tooth structure.
 2. Biocompatibility of the polycarboxylate cements
with the translucency and hardness.
 3. Fluoride release of the silicate cements.
 The glass ionomer sealant was believed to be a
useful product, based on the chemical
composition, handling and fluoride release
properties, despite reports that these sealants have
very low retention rates.

 GIC is more suitable for use in young children with
incompletely erupted molars.
Rubenstein LK, Dinius A. Dental sealant usage in Virginia. J
Public Health Dent 1986;46:147-51.
 The primary advantage of GIC over conventional
BIS-GMA sealants is the capability of glass ionomer
to release fluoride, which among other beneficial
effects may result in an increased resistance of
fissures to demineralization.

techniques on the microleakage of compomer and resin fissure
sealants. J Dent Child (Chic) 2003;70:250-3.
 Simonsen concluded that differences in
caries prevention between resinbased and
glass ionomer sealants remain equivocal.
Mascarenhas AK, Moursi AM. Use of fissure sealant retention as
an outcome measure in a dental school setting. J Dent Educ
2001;65:861-5.
 The caries preventive effect of a glass ionomer
sealant depends on both retention of the sealant
and fluoride release.
 The poor retention of glass ionomer sealants
probably precludes them from use as sealants,
particularly in lieu of evidence of superior caries
prevention despite the poor retention.
Donly KJ, García-Godoy F. The use of resin-based composite in
children. Pediatr Dent 2002;24:480-8.
 In the literature, caries preventive effects are
reported to prevail even after the visible loss of the
GIC sealant.
Seth S. Glass ionomer cement and resin-based fissure sealants
Are equally effective in caries prevention. J Am Dent Assoc
2011;142:551-2.
 One main reason for the loss of the glass ionomer
sealants could be inadequate adhesion of the
cement to the enamel surface.
Eronat N, Bardakçi Y, Sipahi M. Effects of different preparation
techniques on the microleakage of compomer and resin fissure
sealants. J Dent Child (Chic) 2003;70:250-3.
 In addition, glass ionomer sealants may have been
exposed to saliva before it had completely set,
which could predispose to surface degradation and
early loss of sealant.

 With the introduction of resin modified
glass ionomer, properties regarding,
adherence, esthetics and manipulation have
been improved.
 In addition, maintenance of anticaries and
cariostatic effect has been obtained due to
their continuous fluoride release.

 The disease susceptibility of the tooth should be
considered when selecting teeth for sealants not
the age of the individual.
 1. Ages 3 and 4 years are the most important
times for sealing the eligible deciduous teeth.
 2. Ages 6-7 years for the first permanent molars.
 3. Ages 11-13 years for the second permanent
molars and premolars.

Few clinical sealant trials have measured effectiveness on
buccal surfaces of mandibular molars and lingual surfaces
of maxillary molars.
Those few that report on these surfaces generally report greater
failures on buccal and lingual sealants than on occlusal
sealants.
More recent work suggests that sealants can be placed
successfully on buccal and Lingual surfaces.
Of particular interest is the observation that adding an
intermediate layer of bonding agent primer and adhesive is
more advantageous on these surfaces than it is on occlusal
surfaces.
This may be due to the added flexibility
and stress-breaking effect afforded by the unfilled
adhesive layer and the benefit this flexibility has on
the sealant bond to a buccal or lingual surface
Undergoing continuous flex in the process of
mastication.
Cleaning the pit and fissure surfaces
 Plaque and debris might interfere with the etching
process or sealant penetration.
 Historically, it has been advocated to clean the
surfaces with bristle brush and pumice.
 Use of prophy pastes, especially those with fluoride,
have been discouraged because it was thought that
the fluoride might make the enamel surface less
reactive to the etchant and thereby reduce the bond
strength.
 Air abrasion also has been suggested for preparation
of the occlusal surface before sealant application.
For years there existed an opinion that a recent fluoride
exposure, such as in-office fluoride treatment, would
Interfere with the etching pattern and, therefore, the
Retention of sealants.
This opinion is not correct. It has been dispelled
in several reports using sealant bonding and
Orthodontic bracket bonding to test the
hypothesis.Therefore, sealant application can be
planned to follow fluoride treatment during the same
office appointment if desired.

 Adequate isolation is the most critical aspect of the
sealant application process.
 Salivary contamination of a tooth surface during or
after acid etching will have a deleterious effect on the
ultimate bond between enamel and resin.
 The rubber dam, when properly placed, provides the
best, most controllable isolation, and for an operator
working alone, it ensures isolation from start to
finish.
 Cotton roll isolation offers some advantages over
rubber dam isolation.
 Introduction of acid etch technique has made the
sealing of occlusal surfaces more effective.
 The most critical step in sealant application
technique is acid conditioning or acid etching
procedure.
 Etching enhances the tooth’s receptivity to bonding
with the sealant.
 During this critical step, meticulous maintenance of
a dry tooth surface is essential for bonding to be
successful.

J Clin Pediatr Dent 2002;26:175-8.
 The conventional 60 s etching was first used by
Ripa and Cole.
 Increased etching time for deciduous teeth is
attributed to various reasons like:
1. Deciduous teeth have less mineral and more
organic material in the enamel.
2. Deciduous teeth have a larger internal pore
volume and thus more exogenous organic material.
3. Deciduous teeth have more prism less enamel on
their surface than do permanent teeth.
4. The prism rods in deciduous teeth approach the
surface at a greater angle and thus are more
difficult to etch.
Three characteristic etching patterns occur following
exposure of sound enamel to phosphoric acid.
Gray GB. An evaluation of sealant restorations after 2 years. Br
Dent J 1999;186:569-75.
1. Type 1 etching pattern: Prism cores lost but Prism
peripheries remain — honeycomb appearance.
2. Type 2 etching pattern: Prism peripheries are lost,
Prism cores appear to be relatively intact — cobble
stone appearance.
3. Type 3 etching pattern: Some regions of etched
Enamel show a generalized surface roughening and
porosity with no exposure of prism cores or
peripheries.
 Earlier it was recommended that the etching time
for primary teeth be doubled than that of the
permanent teeth.
 Many studies have used different etching timing
from 15 to 60 sec.
 Tandon S.et al have proposed an etching timing of
15 sec to be sufficient for primary teeth.
 Many of the sealant manufacturers recommend
rinsing the tooth for 20-30 s to remove the etchant.
 An exact rinse time is probably not as important as
ensuring that the rinse is long enough and thorough
enough to remove all of the etchant
from the surface.
Drying the tooth with compressed air is likewise done
not for a specific time but rather for a specific result.
 A tooth that is completely dried will exhibit a
chalky, frosted appearance.
 During sealant application, all the susceptible pits
and fissures should be sealed for maximum caries
protection.
 This includes buccal pits of mandibular molars and
lingual grooves of maxillary molars.
 The sealant material can be applied to the tooth in
a variety of methods.
 Many sealant kits have their own dispensers, some
preloaded that directly apply the sealant to the
tooth surface.
 Some common problems occur during
sealant application.
 Small bubbles may form in the sealant material.
 If these are present, they should be teased out
with a brush before polymerization.
 Unfilled sealants have a low viscosity that makes
them prone to pooling in the distal pit area of
maxillary molars due to patient position and
gravity.
 This can be rectified by applying the sealant
judiciously or by removing excess amounts with a
brush.
 The sealant should be visually and tactually inspected
for complete coverage and absence of voids or
bubbles.
 Attempts should be made to dislodge the sealant
with an explorer.
 If the sealant is dislodged, the tooth should be
carefully inspected to see that no debris has been left
in the fissure, which may have interfered with the
bond.
 Small voids in the sealant can be repaired simply by
adding new material to the void and polymerizing.
 Some sealants will be completely or partially lost
and will require reapplication.
 During routine recall examinations, it is necessary
to re-evaluate the sealed tooth surface both
visually and tactually for loss of material, exposure
of voids in the material and caries development.
 The need for reapplication of sealants is usually
highest during the first 6 months after placement.
A previous review of sealant clinical trials show a
failure rate (judged by sealants needing repair,
replacement or restoration) to be between 5% and
10% each year.
This number is supported in many large sealant
studies and in numbers from private pediatric
practices using the best of sealant procedures.
Without appropriate clinical follow-up of these
sealants, the failures would compound over a
few years, leaving most of the surfaces equally
susceptible to caries as surfaces that were never
sealed.
Long-term success of sealant therapy, therefore, is
dependent upon vigilant recall and repair when
necessary.
With such follow up, sealant success is very high.
Caries is a problem for patients of all ages.
Along with proper diet, fluoride, and biofilm control,
pit and fissure sealants should be considered as part
of an overall preventive program rather than an
isolated procedure.
Ideally, high-risk patients should have sealants
placed on all posterior permanent teeth upon
eruption.
The dental practitioner should be familiar with the
various categories of sealants and the specific
application methods for each product.
With proper placement and maintenance, sealants
can last years.
The dental literature supports:
1. Bonded resin sealants, placed by appropriately
trained dental personnel, are safe and effective in
preventing pit and fissure caries on at-risk
surfaces. Effectiveness is increased with good
technique and appropriate follow up and resealing
as necessary.
.
2. Sealant benefit is increased by placement on
surfaces judged to be at high risk or surfaces that
already exhibit incipient carious lesions. Placing
sealant over minimal enamel caries has been
shown to be effective at inhibiting lesion
progression. Appropriate follow-up care, as with
all dental treatment, is recommended
3. Presently, the best evaluation of risk is done by an
experienced clinician using indicators of tooth
morphology, clinical diagnostics, past caries history,
past fluoride history and present oral hygiene.
4. Caries risk, and therefore potential sealant
benefit, may exist in any tooth with a pit or fissure,
at any age, including primary teeth of children and
permanent teeth of children and adults.
5. Sealant placement methods should include careful
cleaning of the pits and fissures without removal of
any appreciable enamel. Some circumstances may
Indicate use of a minimal enameloplasty technique.
6. A low-viscosity, hydrophilic material bonding layer
as part of or under the actual sealant has been
shown to enhance the long-term retention and
effectiveness.
7. Glass ionomer materials have been shown to be
ineffective as pit and fissure sealants, but could be
used as transitional sealants.
8. The profession must be alert to new preventive
methods effective against pit and fissure caries.
These may include changes in dental materials or
technology.

Pit and fissure sealants in pediatric dentistry

  • 1. Presented by Karuna sharma Babu G, Mallikarjun S, Wilson B, Premkumar C. Pit and fissure sealants in pediatric dentistry. SRM J Res Dent Sci 2014;5:253-7.
  • 2.  Dental caries remains as one of the most widespread disease of mankind.  It is the single most common chronic childhood disease.  Caries in children begins shortly after eruption of the deciduous teeth and continue to increase at a remarkable rate in their school age.
  • 3.  Deep pits and fissures favor food retention and are difficult to clean by routine brushing.  It provides a favorable environment for the oral microorganisms to thrive and convert the carbohydrates to acids, leading to demineralization of the enamel. Muthu MS, Sivakumar N. Pediatric dentistry. Principles and Practice.1st ed. New Delhi: Elsevier; 2009.
  • 4.  The most efficient way to prevent pit and fissure caries is by effectively sealing the fissures using resins called pit and fissure sealants.
  • 5.  There have been many attempts made within past decades to prevent the development of caries, in particular occlusal caries as it was once generally accepted that pits and fissures of teeth would become infected with bacteria within 10 years of erupting into the mouth .
  • 6.  Years Authors Contribution  1895 Wilson Placement of zinc phosphate  cement in pits and fissures  1923 Hyatt Prophylactic odontomy  1942 Kline and Knutson Treatment with ammoniacal silver  nitrate  1955 Buonocore Sealing of pits and fissure with  bonded resin material  1971 Pit and fissure sealant recognized  by ADA  1978 Simonson Preventive resin restoration  1986 Garcia-Godoy Preventive glass ionomer restoration ADA: American dental association Bowen in 1965 reported BIS-GMA material development.
  • 7.  BIS-GMA resin is the reaction product of bisphenol A and glycidylmetharylate.  It is the base resin to most of the current commercial resin.  Urethane dimethacrylate and other dimethacrylates resins are also used in the sealant materials.
  • 8. Based on filler content  Sealants are classified into filled and unfilled resin systems in regard to the presence or absence of filler particles in the system, but most of the self- cured resins are unfilled. Kervanto-Seppälä S, Pietilä I, Meurman JH, Kerosuo E. Pit and fissure sealants in dental public health — Application criteria And general policy in Finland. BMC Oral Health 2009;9:5.
  • 9.  The filled sealants contain microscopic glass beads, quartz particles, and other fillers used in composites resins.  The fillers are coated with products such as silane, to facilitate their combination with the bisphenol A and glycidyl methacrylate (BIS-GMA) resin.
  • 10. The fillers make the resin more resistant to abrasion and wear. In contrast, unfilled sealants wear quicker, but usually do not need occlusal adjustment. Unfilled resins will penetrate deeper into the fissure system, and therefore perhaps be better retained.

  • 22. In preventive dentistry, CA was also the first material modified for use as a pit and fissure sealant to help prevent dental decay, especially on the occlusal surface. However, because this material biodegrades and does not last long in the oral cavity, it was later replaced with other dental materials, such as GMA dimethacrylate. Pinkham J, Casamassimo P.

  • 35.  Two methods of fluoride incorporation into pit and fissure sealants are used. In first method, fluoride is added to unpolymerized resin in the form of a soluble fluoride salt.  After the sealant is applied to the tooth, salt dissolves and fluoride ions are released, Helioseal- F is produced based on this procedure.
  • 36.  The second method of incorporating fluoride is by addition of an organic fluoride compound that is chemically bound to the resin to form an ion exchange resin; Teethmate F-1 is based on this method.

  • 44.  The caries preventive effect of a glass ionomer sealant depends on both retention of the sealant and fluoride release.  The poor retention of glass ionomer sealants probably precludes them from use as sealants, particularly in lieu of evidence of superior caries prevention despite the poor retention. Donly KJ, García-Godoy F. The use of resin-based composite in children. Pediatr Dent 2002;24:480-8.

  • 46.  One main reason for the loss of the glass ionomer sealants could be inadequate adhesion of the cement to the enamel surface. Eronat N, Bardakçi Y, Sipahi M. Effects of different preparation techniques on the microleakage of compomer and resin fissure sealants. J Dent Child (Chic) 2003;70:250-3.  In addition, glass ionomer sealants may have been exposed to saliva before it had completely set, which could predispose to surface degradation and early loss of sealant.

  • 49.  The disease susceptibility of the tooth should be considered when selecting teeth for sealants not the age of the individual.  1. Ages 3 and 4 years are the most important times for sealing the eligible deciduous teeth.  2. Ages 6-7 years for the first permanent molars.  3. Ages 11-13 years for the second permanent molars and premolars. Brown LJ, Selwitz RH. The impact of recent changes in the epidemiology of dental caries on guidelines for the use of dental sealants.

Evaluation after 4 years of the combined use of fluoride and dental sealants. Community Dent Oral Epidemiol 1995;23:30-5.  The shallow wide V and U shaped fissures tend to be self-cleansing and somewhat caries resistant.  The deep narrow I and IK shaped fissures are susceptible to caries.
  • 51. CRITERIA INDICATIONS CONTRAINDICATIONS Tooth age Recently erupted Teeth remains caries free for 4 or >4 years Tooth type Molar Premolar except when caries risk is high Occlusal morphology Deep narrow retentive pit and fissures Narrow wide self- cleansing pit and fissures Status of proximal surface Sound Carious General caries activity Many occlusal lesions few proximal lesions Many proximal lesions Other preventive measures Patient receiving approach systemic and topical F therapy and are still caries active
  • 52. Few clinical sealant trials have measured effectiveness on buccal surfaces of mandibular molars and lingual surfaces of maxillary molars. Those few that report on these surfaces generally report greater failures on buccal and lingual sealants than on occlusal sealants. More recent work suggests that sealants can be placed successfully on buccal and Lingual surfaces. Of particular interest is the observation that adding an intermediate layer of bonding agent primer and adhesive is more advantageous on these surfaces than it is on occlusal surfaces.
  • 53. This may be due to the added flexibility and stress-breaking effect afforded by the unfilled adhesive layer and the benefit this flexibility has on the sealant bond to a buccal or lingual surface Undergoing continuous flex in the process of mastication.
  • 54. Cleaning the pit and fissure surfaces  Plaque and debris might interfere with the etching process or sealant penetration.  Historically, it has been advocated to clean the surfaces with bristle brush and pumice.  Use of prophy pastes, especially those with fluoride, have been discouraged because it was thought that the fluoride might make the enamel surface less reactive to the etchant and thereby reduce the bond strength.  Air abrasion also has been suggested for preparation of the occlusal surface before sealant application.
  • 55. For years there existed an opinion that a recent fluoride exposure, such as in-office fluoride treatment, would Interfere with the etching pattern and, therefore, the Retention of sealants. This opinion is not correct. It has been dispelled in several reports using sealant bonding and Orthodontic bracket bonding to test the hypothesis.Therefore, sealant application can be planned to follow fluoride treatment during the same office appointment if desired. Brannstrom M, Nordenvall KJ, Malmgran O. The effect of various pretreatment methods on the enamel in bonding procedures. Am J Orthod. 1955;74:522-530. Warren DP, Infante NB, Rice HC, Turner SD, Chan JT. Effect of topical fluoride on retention of pit and fissure sealants. J Dent Hygiene. 2001;75:21-24.
  • 56.  Adequate isolation is the most critical aspect of the sealant application process.  Salivary contamination of a tooth surface during or after acid etching will have a deleterious effect on the ultimate bond between enamel and resin.  The rubber dam, when properly placed, provides the best, most controllable isolation, and for an operator working alone, it ensures isolation from start to finish.  Cotton roll isolation offers some advantages over rubber dam isolation.
  • 57.  Introduction of acid etch technique has made the sealing of occlusal surfaces more effective.  The most critical step in sealant application technique is acid conditioning or acid etching procedure.  Etching enhances the tooth’s receptivity to bonding with the sealant.
  • 58.  During this critical step, meticulous maintenance of a dry tooth surface is essential for bonding to be successful. Gillet D, Nancy J, Dupuis V, Dorignac G. Microleakage and Penetration depth of three types of materials in fissure sealant: Self-etching primer vs etching: An in vitro study. J Clin Pediatr Dent 2002;26:175-8.  The conventional 60 s etching was first used by Ripa and Cole.
  • 59.  Increased etching time for deciduous teeth is attributed to various reasons like: 1. Deciduous teeth have less mineral and more organic material in the enamel. 2. Deciduous teeth have a larger internal pore volume and thus more exogenous organic material. 3. Deciduous teeth have more prism less enamel on their surface than do permanent teeth. 4. The prism rods in deciduous teeth approach the surface at a greater angle and thus are more difficult to etch.
  • 60. Three characteristic etching patterns occur following exposure of sound enamel to phosphoric acid. Gray GB. An evaluation of sealant restorations after 2 years. Br Dent J 1999;186:569-75. 1. Type 1 etching pattern: Prism cores lost but Prism peripheries remain — honeycomb appearance.
  • 61. 2. Type 2 etching pattern: Prism peripheries are lost, Prism cores appear to be relatively intact — cobble stone appearance. 3. Type 3 etching pattern: Some regions of etched Enamel show a generalized surface roughening and porosity with no exposure of prism cores or peripheries.
  • 62.  Earlier it was recommended that the etching time for primary teeth be doubled than that of the permanent teeth.  Many studies have used different etching timing from 15 to 60 sec.  Tandon S.et al have proposed an etching timing of 15 sec to be sufficient for primary teeth.
  • 63.  Many of the sealant manufacturers recommend rinsing the tooth for 20-30 s to remove the etchant.  An exact rinse time is probably not as important as ensuring that the rinse is long enough and thorough enough to remove all of the etchant from the surface. Drying the tooth with compressed air is likewise done not for a specific time but rather for a specific result.
  • 64.  A tooth that is completely dried will exhibit a chalky, frosted appearance.
  • 65.  During sealant application, all the susceptible pits and fissures should be sealed for maximum caries protection.  This includes buccal pits of mandibular molars and lingual grooves of maxillary molars.  The sealant material can be applied to the tooth in a variety of methods.  Many sealant kits have their own dispensers, some preloaded that directly apply the sealant to the tooth surface.
  • 66.  Some common problems occur during sealant application.
  • 67.  Small bubbles may form in the sealant material.  If these are present, they should be teased out with a brush before polymerization.  Unfilled sealants have a low viscosity that makes them prone to pooling in the distal pit area of maxillary molars due to patient position and gravity.  This can be rectified by applying the sealant judiciously or by removing excess amounts with a brush.
  • 68.  The sealant should be visually and tactually inspected for complete coverage and absence of voids or bubbles.  Attempts should be made to dislodge the sealant with an explorer.  If the sealant is dislodged, the tooth should be carefully inspected to see that no debris has been left in the fissure, which may have interfered with the bond.  Small voids in the sealant can be repaired simply by adding new material to the void and polymerizing.
  • 69.  Some sealants will be completely or partially lost and will require reapplication.  During routine recall examinations, it is necessary to re-evaluate the sealed tooth surface both visually and tactually for loss of material, exposure of voids in the material and caries development.  The need for reapplication of sealants is usually highest during the first 6 months after placement.
  • 70. A previous review of sealant clinical trials show a failure rate (judged by sealants needing repair, replacement or restoration) to be between 5% and 10% each year. This number is supported in many large sealant studies and in numbers from private pediatric practices using the best of sealant procedures.
  • 71. Without appropriate clinical follow-up of these sealants, the failures would compound over a few years, leaving most of the surfaces equally susceptible to caries as surfaces that were never sealed. Long-term success of sealant therapy, therefore, is dependent upon vigilant recall and repair when necessary. With such follow up, sealant success is very high.
  • 72. Caries is a problem for patients of all ages. Along with proper diet, fluoride, and biofilm control, pit and fissure sealants should be considered as part of an overall preventive program rather than an isolated procedure. Ideally, high-risk patients should have sealants placed on all posterior permanent teeth upon eruption.
  • 73. The dental practitioner should be familiar with the various categories of sealants and the specific application methods for each product. With proper placement and maintenance, sealants can last years.
  • 74. The dental literature supports: 1. Bonded resin sealants, placed by appropriately trained dental personnel, are safe and effective in preventing pit and fissure caries on at-risk surfaces. Effectiveness is increased with good technique and appropriate follow up and resealing as necessary. .
  • 75. 2. Sealant benefit is increased by placement on surfaces judged to be at high risk or surfaces that already exhibit incipient carious lesions. Placing sealant over minimal enamel caries has been shown to be effective at inhibiting lesion progression. Appropriate follow-up care, as with all dental treatment, is recommended
  • 76. 3. Presently, the best evaluation of risk is done by an experienced clinician using indicators of tooth morphology, clinical diagnostics, past caries history, past fluoride history and present oral hygiene.
  • 77. 4. Caries risk, and therefore potential sealant benefit, may exist in any tooth with a pit or fissure, at any age, including primary teeth of children and permanent teeth of children and adults.
  • 78. 5. Sealant placement methods should include careful cleaning of the pits and fissures without removal of any appreciable enamel. Some circumstances may Indicate use of a minimal enameloplasty technique. 6. A low-viscosity, hydrophilic material bonding layer as part of or under the actual sealant has been shown to enhance the long-term retention and effectiveness.
  • 79. 7. Glass ionomer materials have been shown to be ineffective as pit and fissure sealants, but could be used as transitional sealants. 8. The profession must be alert to new preventive methods effective against pit and fissure caries. These may include changes in dental materials or technology.
