  29. 29. LONG TERM TREATMENT PLANNING Overall assessment of the general attitude of the child and parents to dental care “ Delaying the final treatment planning until the acute problems have resolved is very worthwhile” www.indiandentalacademy.comwww.indiandentalacademy.com
  30. 30. Order of treatment: general guidance First visit  Take radiographs.  Introduce the child to operative treatment-'polish' a few teeth or full prophylaxis. www.indiandentalacademy.comwww.indiandentalacademy.com
  31. 31. 2nd visit  Assess tooth brushing technique - observe the child brushing - determine Oral Debris Index Stan oral hygiene instruction  Topical fluoride or fissure sealant or preventive resin restoration.  Provide a diet record leaflet and explain its purpose to the parent and/or child. www.indiandentalacademy.comwww.indiandentalacademy.com
  32. 32. 3rd visit  Collect diet record leaflet.  Continue oral hygiene instructions  Amalgam restoration in maxillary molar-infiltration local analgesia­ www.indiandentalacademy.comwww.indiandentalacademy.com
  33. 33. Fourth visit Continue oral hygiene instruction. At this and subsequent visits, introduce progressively to more complex restorations. Delaying treatment of mandibular teeth if possible until the child happily accepts maxillary infiltrations. Diet counseling. www.indiandentalacademy.comwww.indiandentalacademy.com
  34. 34. Rampant caries • Consider gross caries removal and temporization • Discuss baby bottle syndrome if the patient is young • Consider diet history and extended oral hygiene instructions with parent • Consider fluoride supplementation, either systemic or topical www.indiandentalacademy.comwww.indiandentalacademy.com
  35. 35. Pain • Always treat the area that is painful to the patient, regardless of treatment plan order • Never let a patient leave in pain! www.indiandentalacademy.comwww.indiandentalacademy.com
  36. 36. Two factors significantly reduce the survival rate of restorations ……….walls et al 1985  Lack of local analgesia  Age of the patient  Topical analgesia before giving an injection  Careful measured technique with full explanation to the child through out the local anesthesia procedure flavoured topical gel fine gauge needle warmed analgesia solution slow administration of the solution constant reinforcementwww.indiandentalacademy.comwww.indiandentalacademy.com

  69. 69. Why Ligate the Clamp?  All retainers applied before the rubber dam is in place must be ligated. A 12” piece of floss should be attached to the retainer and threaded though both holes to catch all of the pieces should the retainer break.  Prevents the patient accidentally swallowing the clamp.  Prevents injury to the dental team from flying debris caused by an improper seat of the clamp. www.indiandentalacademy.comwww.indiandentalacademy.com

  80. 80. TECHNIQUE 3 - Clamp placed after the rubber dam  It should be carried out with assistance  Restricted to anterior teeth and possibly pre-molar because of limited access  When large sized clamps are used www.indiandentalacademy.comwww.indiandentalacademy.com
  81. 81. MULTIPLE TOOTH ISOLATION  Clamps should not be placed on a tooth which requires which requires restoration  If the is narrow mesio-distally then the second tooth to the distal is preferable  When several teeth require treatment the operating field is extended mesially or across the arch to provide clear access and maximum retention  Distal tooth will usually be clamped and the mesial is not clamped www.indiandentalacademy.comwww.indiandentalacademy.com

  110. 110.  Method for glass ionomer restorations 1. Local anesthesia may not always be necessary; however, rubber dam isolation should be used where possible 2. The outline of the cavity should follow the extent of the carious lesion. There should be no extension for prevention. An additional retention form for minimal proximal cavities can be achieved by placing grooves into the dentine using very small (size 1 –2 )round burs  3.Remove all soft caries using a slow round burr or hand instruments. Be aware of the large pulp chamber as it is easy to expose the pulp of a primary molar.  4.Pre-condition the dentine using 10%polyacrylic acid for 10 seconds, wash and dry. www.indiandentalacademy.comwww.indiandentalacademy.com
  111. 111. 5.When using encapsulated materials, ensure that the capsules are compressed for atleast 3 seconds to facilitate adequate mixing of the powder and liquid components. Mix for 10 seconds in the amalgamator, discard the rest 3 –4 mm of the mixed materials as this is often unsatisfactory. Place the remainder directly into the cavity. 6.Once the relatively thick material has been placed into the cavity it is compressed with a ball burnisher – the use of a small amount of bonding agent prevents sticking to the instrument. www.indiandentalacademy.comwww.indiandentalacademy.com
