1 Pulpotomy Access Technique Cynthia Christensen, DDS, MS Department of Pediatric Dentistry

2 Pulp Therapy for Primary Teeth Michael Kanellis, DDS, MS Department of Pediatric Dentistry

3 Pulpotomy Pulpotomy is the extirpation of vital inflamed pulp from the coronal chamber followed by medicament placement over radicular pulp stumps to fix (mummification) or stimulate repair of the remaining vital radicular pulp.

4 Pulpotomy Rationale: The radicular pulp tissue is healthy, and can either heal after the surgical amputation of the coronal pulp, or be fixed/mummified. Signs or symptoms of inflammation extending beyond the coronal pulp is a contraindication for a pulpotomy

5 Pulpotomy - Indications When the pulp is exposed (either through carious exposure or through trauma) When it is desirable to maintain tooth (primarily for space, function, guidance of permanent teeth) When there are no contraindications to pulpal therapy

6 Pulpotomy Procedure 1.Rubber Dam Isolation 2.Remove caries 3.Open pulp chamber and de-roof 4.Amputate pulp with round bur in slow speed running in reverse 5.Control hemorrhage with dry cotton pellet 6.Place Endo Bleach or FMC????? 7.Place Glass Ionomer over floor?????

7 Although the Medicaments and Materials May Change… The Access Opening Technique Will Remain the Same

8 Pulpotomy Access Technique

9 Remove caries Pulp exposed

10 Primary Pulp Chambers Short vertical dimension Thin floor

11 Therefore: Perforation of Floor is Much Greater Risk in Primary Molars

12 What happened here? PrePost

13 Radiographic Appearance Perforation Proper Appearance 11/17/03

14 Access Opening Must Be LARGE Root orafices splayed to accommodate succedaneous tooth.

15 Access Opening Must Be LARGE Convenience Form to Amputate Radicular Orafice

16 Edontontic Department Will Teach You to Do A Conservative Access Opening

17 That is correct for Permanent Teeth!!

18 PRIMARY TEETH ARE DIFFERENT

19 Why Not Do an Access That Conserves Tooth Structure? Has nothing to do with SSC Restoration Retention –Cervical Bulge Intact Convenience Form Needed –Not using flexible files

20 Place cotton pellet and pressure to control initial hemhorrage

21 Remove cotton pellet Irrigate with NaOH? Place GI? Place stainless steel crown

22 Rubber dam isolation

23 Remove caries Deep caries with pulp exposure

24 Open pulp chamber and “de-roof”

25 Amputate pulp with slow speed in reverse.

26 Control Hemorrhage with Cotton Pellet

27 Remove cotton pellet: Residual Bleeding Why???

28 Tissue Tags Remain: Not Amputated at Canal Orafices

29 Let’s Try A Larger Access Opening

30 Caries removal with pulp exposure

31 Outline of access opening

32 Access opening complete and pulp chamber tissue amputated

33 Placement of cotton pellet

34 Hemostasis Acheived

35 Place Medicaments and Liner

36 Restore with SSC

37 Mandibular First Primary Molar

38 Thank You!
