Optimal outcomes of pulpotomy in young patients: Long-term prospects for permanent molars with signs and symptoms indicative of irreversible pulpitis.

Objectives: Limited literature addresses the long-term success of complete pulpotomy in permanent molars with signs of irreversible pulpitis in young patients. The aim of this observational study was to prospectively evaluate the long-term outcomes of complete pulpotomy using mineral trioxide aggregate (MTA) over an average period exceeding 11 years.

Methods: Out of 27 molars displaying signs suggestive of irreversible pulpitis which underwent MTA pulpotomy, 24 molars were followed-up for a mean duration of 11.0 ± 2.2 years (range 8.2 to 14.8 years). Clinical and radiographic assessments were periodically conducted, tailored to each patient's specific circumstances. Treatment failure criteria included clinical signs and symptoms and radiographic evidence suggesting a lack of pulpal or periapical healing.

Results: 83 % of molars had signs and symptoms of symptomatic irreversible pulpitis, with 83 % displaying apical periodontitis. Clinically and radiographically, all pulpotomies (100 %) were considered successful. A hard tissue barrier was observed in 71 % of teeth, and continued root maturation was evident in all molars with open apices. Complete pulp canal obliteration (PCO) was present in 21 % of the molars. All radiographic apical radiolucencies completely resolved.

Conclusions: This study demonstrates a 100 % success rate over an average 11-year follow-up for complete pulpotomy in managing permanent molars with signs and symptoms of irreversible pulpitis in young patients. It offers evidence for its long-term efficacy in promoting healing of pulp and periapical tissues.

Clinical Significance: This study showed high long-term success for complete pulpotomy in young permanent molars with irreversible pulpitis, with clinical and radiographic success over 11 years. Despite initial symptoms of pulpitis and apical periodontitis, the treatment resulted in tissue healing, root maturation, and resolution of periapical radiolucencies, suggesting it as an alternative to root canal therapy.
