Outcome of Partial Pulpotomy in Immature Permanent Teeth with Symptomatic Irreversible Pulpitis: A Prospective Case Series Assessment

Abstract

Introduction

The aim of this prospective case series was to assess the clinical and radiographic outcome of partial pulpotomy in caries-exposed symptomatic, vital, immature, permanent molars.

Methods

Thirty-four immature molars with deep caries and symptoms of irreversible pulpitis were treated by partial pulpotomy and ProRoot MTA as a capping material. After complete caries removal, the inflamed part of the pulp was removed. Complete hemostasis was achieved using a sterile cotton pellet moist initially with sodium hypochlorite 1.5% and then with sterile saline. ProRoot MTA (Dentsply Sirona, Charlotte, NC) was placed as a capping material onto the remaining pulp tissue. The cavity was sealed using a light-curing resin-modified Ca(OH)₂ cavity liner, and patients were referred to a pediatric dentist for permanent restoration. Descriptive statistics and cross tabulations were performed including variables examined before, during, and after the procedure.

Results

All examined teeth presented a favorable clinical and radiographic outcome with normal periapical tissues, complete apical closure, and formation of a dentinal bridge beneath the capping material. Signs of partial pulp chamber calcification were only detected in 2 cases. Postoperatively, most patients did not report any pain (23/34, 67.7%), whereas the rest reported minor intensity pain (11/34, 32.3) and the use of analgesic or anti-inflammatory drugs only for 1 day (10/34, 29.4%).

Conclusions

Partial pulpotomy seems to provide a universally successful outcome when managing symptomatic vital immature teeth with no signs of complications and completion of apical closure. It could be a viable treatment of choice in cases of caries-exposed vital immature teeth with symptoms of irreversible pulpitis.
