Summary:While root resective therapy may extend the longevity of a molar, data on patient selection and outcomes of root resection are scarce. The purpose of this retrospective cohort study was to analyze the survival of root-resected molars and investigate factors affecting the decision and outcomes of the therapy. Patient- and tooth-related data from participants who had received root resection between 1999 and 2022 were collected. Cox regression was used to build predictive models for time-to-tooth loss based on predictors—initial diagnoses (carious, endodontic, periodontal, or endodontic-periodontal lesions), the presence of a complete-coverage crown, and the location of the tooth in the arch (P
