Anticaries Agent
• Dental caries or tooth decay is caused by
acid produced by the action of
microorganism or carbohydrates, it
involves decalcification of the tooth
accompanied by foul odour
• Dental caries or cavities are formed by
the growth and implantation of
microorganisms on surface of teeth.
• Dental caries can be prevented by
maintaining the oral and dental hygiene
with the help of dentifrices.
• Enhance the removal of stain and dental
plaque.
• Cleaning Agents or Dentifrices
Dentifrices or cleaning agents are the
inorganic substance which is used for
cleaning teeth and adjacent gums.
These agents are responsible for physically
removing plaque and debris
• Dentifrices contain agents deanting
tooth surface and providing polishing
effect on the cleaned tooth.
• Examples for dentifrices include calcium
carbonate, dibasic calcium phosphate
Desensitizing agents
• Usually teeth are somewhat sensitive to
heat and cold.
• Especially during teeth decay or toothache.
• The perception of heat and cold has been
felt strongly.
• Desensitizing agents are used in dental
preparation so as to reduce sensitivity of
teeth to heat and cold
• The exact mechanism is not known.
• They act probably like local anaesthetic
• Examples: Zinc chloride, strontium chloride.
• Cement and Fillers
Dental cements are used to temporarily
cover or protect the area that has
undergone operation as in dental surgery.
The temporary cement is also
medicated usually with eugenol which is
antiseptic and local anaesthetic.
• Fillers:
• It is used for temporary fillings.
• It can be used as Pulp capping agent and
Cavity Liners
• The secondary use of zinc eugenol
cement is root canal restorations
• The consistency of the cement can be
controlled by additives.
• A cement of suitable consistency finds
use as temporary fillers for cavities.
• Most often noble metal and their alloys
are used as permanent filing materials.
