1 Pulp Therapy in Pediatric Dentistry Dr. S.E.Jabbarifar Pediatric Dentistry Department Isfahan Dental School

2 Pulp Therapy in Pediatric Dentistry --Vital Pulp Therapy-- Permanent Tooth Pulpotomy –Objectives Maintain vitality of radicular pulp Achieve root-end closure (Apexogenesis) Eliminate need for apicoectomy Facilitate GP obturation with apical stop

3 Pulp Therapy in Pediatric Dentistry --Vital Pulp Therapy-- Permanent Tooth Pulpotomy Agents –F–Formocresol

4 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- Objectives of Non-Vital Pulp Treatment (Primary Teeth) –Maintain tooth free of infection –Achieve biomechanical cleansing and canal obturation –Promote physiologic resorption –Maintain space and function

5 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- Non-Vital Pulp Treatment (Primary Teeth) –C–Choices Pulpectomy (most are partial due to anatomy) Extraction

6 Pulpectomy Indications/Considerations Strategic importance of tooth (2 nd primary molar with unerupted 6-yr molar) Sufficient remaining tooth structure Poor chance of vital pulp treatment success Adequate remaining root Cooperative patient

7 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- Pulpectomy Contraindications –A non-restorable tooth –A tooth with a mechanical or carious perforation of the floor of the pulp chamber –Pathologic root resorption involving more than one- third of the root –Pathologic loss of bone support resulting in loss of the normal periodontal attachment –The presence of a dentigerous or follicular cyst –Radiographically visible internal root resorption

8 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- Pulpectomy Technique 1.Achieve adequate anesthesia and rubber dam isolation. 2.Remove all caries. 3.Remove the roof of the pulp chamber with a high-speed handpiece. 4.Amputate the coronal aspect of the pulp tissue with a large round bur in a slow-speed handpiece. 5.The remaining pulp tissue occupying the root canals is removed using endodontic files at a predetermined working length, approximately 1 to 2 mm short of the root apices. 6.The canals should be enlarged several sizes beyond the size of the first file that fits snugly into the canal to a minimum final size of 30 to Throughout root canal instrumentation, the canals should be irrigated with sodium hypochlorite to aid in debridement.

9 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- Pulpectomy Technique (continued) 8. Dry the canals with sterile paper points. 9.The canals are filled with a treatment paste (Zinc Oxide/Eugenol at UKCD) using a pressure syringe. 10.The tooth is restored with a stainless steel crown.

10 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy--

11 Criteria for an ideal pulpectomy obturant (treatment paste) –A–Antiseptic –R–Resorbable –H–Harmless to the adjacent tooth germ –R–Radiopaque –N–Non-impinging on erupting permanent tooth –E–Easily inserted –E–Easily removed

12 Apexification (Young Permanent Teeth) –Apical closure of an incompletely formed root –Implemented when apexogenesis has failed –Necrotic tissue removal short of the apexification site –Agent is placed in canals to achieve closure/apical stop Apexification Recall Schedule –Calcium Hydroxide Rotation 3-6 month intervals (Andreasen, 1994)

13 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- Action of Calcium Hydroxide in Apexification –Bactericidal –Low grade irritation inducing hard tissue barrier formation –Dissolves necrotic debris Forms of Calcium Hydroxide –Caliscept –Self-mixed (CaOH + sterile water or local anesthetic)

14 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- Evaluation of Success –Asymptomatic –Radiographic absence of pathology –Continued root development –Hard tissue barrier at apex –Responsive pulp

15 Pulp Therapy in Pediatric Dentistry --Non-Vital Pulp Therapy-- In Review...
