Long-term Pulpal and Restorative Outcomes of Pulpotomy in Mature Permanent Teeth.

Introduction: Pulpotomy in mature permanent cariously exposed teeth preserves the remaining pulp tissues, but long-term outcomes of the pulp and the restoration are unknown. This prospective study examined the immediate and long-term status of the pulp and the restored tooth and identified potential predictors of early and late failures in teeth that were asymptomatic or experiencing only mild symptoms at the time of treatment.

Methods: Pulpotomy was performed using the aseptic technique and a tricalcium silicate cement under local anesthesia.

Lesion progression in post-treatment persistent endodontic lesions.

Introduction: Radiographic lesions related to root-filled teeth may persist for long periods after treatment and are considered to indicate failure of initial treatment. Persistent lesions are found in a proportion of cases, but information on lesion progression is lacking. This study examined the incidence of lesion improvement, remaining unchanged, and deterioration among persistent lesions in a group of patients recruited from a university-based clinic and identified potential predictors for lesion progression.
