    Abstract:
    INTRODUCTION: Vital pulp therapy (VPT) is a biological approach to minimally invasive endodontics. This randomized clinical trial aimed to evaluate and compare clinical and radiographic success of 4 VPTs (indirect pulp capping [IPC], direct pulp capping [DPC], miniature pulpotomy [MP], and full pulpotomy [FP]) using calcium-enriched mixture cement for deep caries management of mature permanent molars including teeth with clinical signs of irreversible pulpitis and the presence of apical periodontitis. METHODS: Blinded participants (N = 302) were randomly allocated to 4 study arms. Random allocation was disregarded when visible pulp exposures did not happen after complete caries removal and the tooth was transferred to the IPC arm. Pre- and intraoperative data including vitality test results, pulpal/periapical status, and exposure type/location were recorded. Pain was measured using a numeric rating scale before treatment initiation up to 1 week postoperatively. Participants were followed up for 1 year. RESULTS: The groups were homogenous in terms of age, sex, marital status, education, and practitioner; pre- and intraoperative conditions were similar in all arms and did not affect the long-term success. Preoperative pain and apical periodontitis were significantly different among arms (P < .05); however, it was not the case when the IPC group was excluded. After baseline pain adjustment, pain relief was continuous with similar patterns in all treatment groups. The 3- and 12-month success rates of the VPT techniques were comparable in the IPC (98.7% and 100%, respectively), DPC (98.4% and 94.7%, respectively), MP (98.4% and 91.4%, respectively), and FP (93.5% and 95.5%, respectively) arms, respectively (P > .05). CONCLUSIONS: In deep caries management of mature permanent molars, the 4 VPTs were associated with favorable/comparable clinical and radiographic outcomes. The pulpal and periapical status as well as pulpal exposure type/location had no effect on treatment outcomes.
