Aim and background: To present a case report on partial pulpotomy as an alternative to root canal therapy in a young adult patient with irreversible pulpitis and a normal periodontium. Case description: A case of a young adult patient presenting with a symptomatic irreversible pulpitis in a mature permanent molar tooth was managed with a partial pulpotomy procedure. Following caries removal, pulpal exposure, and haemorrhage control, the exposed pulp tissue was covered with mineral trioxide aggregate (MTA) and a bonded composite restoration.The patient remained asymptomatic at the 1-week, 1-month, and 3-month follow-up visits. Radiographic evaluation showed the presence of a dentinal bridge along the pulp-MTA interface, indicating successful pulp capping and continued root development. Conclusions: Partial pulpotomy can be considered an effective alternative to root canal therapy in young adult patients with irreversible pulpitis and a healthy periodontium. The preservation of pulp vitality, continued root development, and favourable long-term prognosis make it a viable treatment option in appropriate clinical scenarios.
