Abstract

Abstract: Aim: The study aimed to compare the outcome of complete pulpotomy (CP) and partial pulpotomy (PP) techniques when utilised for the management of mature permanent teeth with carious pulpal exposure and symptomatic irreversible pulpitis (SIP). Methodology: The study protocol was registered with ClinicalTrials.gov (NCT04397315). One hundred and six permanent mandibular molars with carious pulpal exposure and clinical diagnosis of SIP with periapical index ≤2, from patients aged between 18 and 40 years were randomly allocated in equal proportion to either CP or PP group. Allocated procedures were performed using standardised protocols. The allocated procedure was abandoned in cases where pulpal bleeding could not be controlled within 6 min using cotton pellets soaked in 3% sodium hypochlorite. MTA was used as a pulpotomy agent and teeth were restored using a base of glass ionomer followed by composite restoration. The pain was recorded by the patient preoperatively before administration of local anaesthesia and postoperatively every 24 h for 1 week using visual analogue scale. Success was analysed at 12 months based on clinical and radiographic examination. Mann–Whitney U test was used to compare age, pain scores and mean analgesic consumption between the groups. Categorical data were analysed using chi‐square test. Fisher's exact test was used to assess the clinical and radiographic success and incidence of pain. Kaplan–Meier analysis was used to assess the survival of teeth. A p ‐value <.05 was considered as statistically significant. Results: One hundred and one patients were analysed at follow up. Higher success was observed in CP (89.8%) in comparison to PP group (80.8%), but the difference was non‐significant statistically ( p = .202). Although no significant difference was observed in pain incidence between the groups at 24 h ( p = .496), a significant difference in pain intensities was observed between groups at all the tested time intervals, with lower values reported in CP group ( p < .05). Conclusions: Both CP and PP resulted in favourable outcomes in the management of cariously exposed permanent teeth with signs indicative of SIP. Given the more conservative nature of PP, it may be attempted first before proceeding to CP in such cases.
