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.
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
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
Pulpotomy Procedure • Rubber Dam Isolation • Remove caries • Open pulp chamber and de-roof • Amputate pulp with round bur in slow speed running in reverse • Control hemorrhage with dry cotton pellet • Place Endo Bleach or FMC????? • Place Glass Ionomer over floor?????
Although the Medicaments and Materials May Change… The Access Opening Technique Will Remain the Same
Remove caries • Pulp exposed
Primary Pulp Chambers • Short vertical dimension • Thin floor
Therefore: Perforation of Floor is Much Greater Risk in Primary Molars

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
Place cotton pellet and pressure to control initial hemhorrage
Remove cotton pellet • Irrigate with NaOH? • Place GI? • Place stainless steel crown
