Comparative evaluation of various biomaterials as pulpotomy agents in molars with symptomatic irreversible pulpitis: A randomized single-blinded single-center control trial.

Introduction: Untreated tooth decay in mature permanent dentition is a prevalent global issue, affecting 34.1% of people with 2.5 billion cases annually. Extensive decay often leads to irreversible pulpitis, characterized by pulp inflammation and pain. Pulpectomy, the standard treatment, involves complex procedures with potential complications. Modern endodontics favors minimally invasive treatment such as pulpotomy, which preserves pulp vitality. This study aims to compare the clinical as well as radiographic outcomes of different pulpotomy agents: Biodentine, mineral trioxide aggregate (MTA), Bio-C repair, and Endosequence Bio-ceramic root repair material (BCRRM) in mature permanent molars.

Methodology: This single-blind, single-center study involved 80 participants randomly assigned to four groups, each receiving one of the biomaterials. Ethical approval was obtained. Participants aged 14-60 years with symptomatic irreversible pulpitis were selected. Pulpotomy procedures were performed, and follow-up evaluations occurred at 24 h, 1 week, 4 weeks, 3, 6, and 12 months. Clinical success was measured by the absence of pain, sensitivity, and tenderness. Radiographic evaluation used the periapical index (PAI) scoring system.

Results: Pulpotomy significantly reduced postoperative pain in all groups. Endosequence BCRRM showed the maximum pain reduction at 24 h with a statistically significant difference from all the groups (at 1% probability level), followed by Bio-C repair, Biodentine, and MTA. At 1 week, Bio-C repair led in pain reduction with statistically nonsignificant results. All groups reported no pain at 3, 6, and 12 months. Endosequence BCRRM had the highest improvement in periapical findings at 1 year. Sensitivity to hot and cold improved significantly in all groups, with Endosequence BCRRM performing best.

Conclusion: Endosequence BCRRM provided the best overall outcomes, emphasizing the importance of material choice in pulpotomy treatments. Further research on biomaterials' long-term clinical and radiographic outcomes is needed to enhance treatment efficacy.
