Comparative evaluation of treatment outcome of partial pulpotomy using different agents in permanent teeth-a...

To compare and evaluate the clinical and radiographic performance, post-operative pain, and anti-inflammatory intake after partial pulpotomy (PP) with calcium hydroxide (CH), mineral trioxide aggregate (MTA), Biodentine (BD), and Emdogain (EMD) as pulp capping agents in mature permanent molars with definitive diagnosis of reversible pulpitis.

As part of this prospective, randomized clinical trial with four parallel arms (CTRI Registration No.: CTRI/2020/11/029329 dated 24/11/2020), hundred and ten permanent molars with a clinical diagnosis of reversible pulpitis and normal apical tissues, from patients between the ages of 15 and 45 years, were recruited and randomly assigned to four groups-CH, MTA, BD, and EMD. Operative procedure was performed under local anesthesia and dental dam isolation. After carious pulpal exposure, 2 mm of superficially inflamed coronal pulp tissue was amputated and either of the four pulp capping materials was placed. The outcome assessment was carried out at 1, 3, 6, and 12 month(s) and was categorized as success (asymptomatic patients with PAI score = 1) or failure (symptomatic patients or PAI score > 1).

There was a significant difference in post-operative pain and anti-inflammatory medication intake after partial pulpotomy with Emdogain vis-à-vis other three capping agents. No difference in both clinical and radiographic performances was observed among the four capping agents.

Partial pulpotomy when performed following evidence-based guidelines results in high success rates regardless of capping agent employed. EMD can be considered a valid and suitable pulp capping agent in PP.

Meticulous examination and removal of superficially inflamed pulp under magnification and complete asepsis lead to successful pulpal healing regardless of capping agent employed.
