Obturating materials for primary teeth

  1. 1. ROOT CANAL OBTURATING MATERIALS FOR PRIMARY TEETH Dept. Of Pedodontics Govt. College of Dentistry, indore Made by :- Bhumika Sharma Pallavi Sehgal B.D.S. Final year (2015-16)
  2. 2. WHAT IS OBTURATION ? • The purpose of obturation phase of endodontic treatment is to prevent the re-infection of root canals that has been biomechanically cleaned, shaped and disinfected by instrumentation, irrigation and medication procedure. • It is essential that endodontic therapy must include sealing of the root canal system to prevent tissue fluids from percolating in the root canal and prevent toxic by – products from both necrotic tissue and microorganism regressing into the peri-radicular tissues.
  3. 3. FILLING OF THE PRIMARY ROOT CANALS • Developmental , anatomic and physiologic differences between the primary and permanent teeth call for differences in the criteria for root canal filling material.
  4. 4. IDEAL REQUIREMENTS • It should resorb at a similar rate as the primary root. • It should be harmless to the periapical tissues and to the permanent tooth germ, if pressed beyond the apex it should resorb readily. • It should have a stable disinfecting power. • It should not be soluble in water.
  5. 5. • It should be inserted easily into the root canal and be removed easily if necessary. • It should adhere to the walls of the canal and should not shrink. • It should be radio opaque. • It should not cause discoloration of the tooth. • It should not coagulate any organic remnants in the canal.
  6. 6. SOME OBTURATING MATERIALS FOR PRIMARY TEETH • Camphorated parachlorophenol (CPC) mixed with calcium hydroxide. • CPC mixed with zinc oxide. • Formocresol mixed with zinc oxide eugenol (ZOE). • Chlorhexidine mixed with ZOE. • KRI paste. • ZOE paste.
  7. 7. • ZOE mixed with sterile water. • Calcium hydroxide with sterile water. • Vitapex • Frank’s paste • Maisto’s paste • Leonardo’s paste iodoform • Walkhoff paste
  8. 8. MOST COMMONLY USED MATERIALS… • Zinc oxide eugenol paste • Calcium hydroxide • Iodoform paste
  9. 9. ZINC OXIDE EUGENOL PASTE • It is the most commonly used root canal filling material for primary teeth.
  10. 10. • Advantages - it has bactericidal effect. - It decreases tooth pain. • Disadvantages - It’s rate of resorption is slower than that of the primary tooth root. - Overfilling causes a mild foreign body reaction. • Success rate is about 65%.
  11. 11. IODOFORM PASTE • It is used as a component in :- -KRI paste -Maisto’s paste -Vitapex -Endoflas • Advantages :- - It resorbs rapidly. -It has no undesirable effect on successor teeth.
  12. 12. • If material is extruded into periapical tissue, it is rapidly replaced by normal tissue. • It has superior antimicrobial action. • It does not set into hard mass and can be removed if re treatment is required. • Success rate is about 84% .
  13. 13. CALCIUM HYDROXIDE • It is generally not used in pulp treatment for primary teeth. • It is used in the form of calcium hydroxide and iodoform mixture due to the following reasons:- • It is found to be easy to apply. • It resorbs at a slightly faster rate than that of the root.
  14. 14. • It has no toxic effects on permanent successor tooth. • It is radio opaque. • This mixture is a nearly ideal material for obturation of primary teeth.
  15. 15. KRI PASTE Composition :- - Iodoform 80.8 % - Camphor 4.86% - Parachlorophenol 2.025 % - Menthol 1.215 %
  16. 16. VITAPEX Composition :- - Calcium hydroxide - Iodoform - Oily additives
  17. 17. WALKHOFF’S PASTE Composition :- - Parachlorophenol - Camphor - Menthol
  18. 18. MAISTO’S PASTE Composition :- - Zinc oxide 14 g - Iodoform 42 g - Thymol 2g - Chlorophenol - Camphor 3cc - Lanolin 0.5 g
  19. 19. ENDOFLAS • It is a root canal sealer material. • It prevents micro leakage. • Success rate is 70%. Composition - Zinc oxide 56.5% - Barium sulphate 1.63% - Iodoform 40.6% - Calcium hydroxide 1.07 % - Eugenol - Pentachlorophenol
  20. 20. COLLA COTE • It is a soft, white, pliable, biocompatible sponge obtained from bovine collagen. • It can be applied to moist or bleeding canals. • It is an absorbable collagen barrier which prevents or diminish extravasations of root canal filling material during primary molar pulpectomies. • Apart from endodontic therapy, it provides scaffold for bone growth. • It can also be applied on wounds.
  21. 21. GUEDES-PINTO PASTE Composition :- - Iodoform 0.30 g - Calcium hydroxide 0.25 g - Camphorated paramonochlorophenol 0.1 ml
  22. 22. FRANK’S PASTE • Composition - Calcium hydroxide - Camphorated parachlorophenol ( CPC ) • Is well tolerated by the adjacent periapical tissue without any inflammation & with deposition of osteodentin.
  23. 23. GUTTA PERCHA • It is not indicated for primary teeth because it is not a resorbable material.
