Statement of Problem: Teeth are weakened after endodontic treatment and should, preferably, be crowned, especially posterior teeth. However, this is not always possible due to certain reasons. Information about the appropriate treatment modalities. This retrospective study was carried out to evaluate the survival of endodontically treated teeth (ETTs) without crown coverage on the basis of various parameters in the region of Vidarbha in Maharashtra, India. Purpose: The aims of this cohort study were to evaluate the survival rate for endodontically treated molars without crown coverage and to identify possible related factors. Materials and Methods: Relevant data from 300 subjects for 148 ETTs was recorded at the Department of Conservative Dentistry and Endodontics, Sharad Pawar Dental College, Wardha, Maharashtra. Follow-up data were derived from a clinical examination and review of the dental record and radiographs. Subjects were not included in the study if teeth had provisional crowns, definitive restorations with cuspal coverage, or with dowel and core and/or crown restorations. The outcome evaluated was defined as a failure if there were negative findings in the condition of a tooth that required a restoration, tooth repair, or extraction. Tooth loss due to endodontic and periodontal reasons was excluded. The independent variables assessed were patient age, gender, location (maxilla or mandible), the existence of an opposing dentition and adjacent teeth, remaining tooth structure, and types of restorative material. One hundred and forty-eight teeth restored using glass-ionomer cement (GIC), SF, and composites were considered successful during the observation time of 3 years because no intervention was needed in these teeth were labeled as “survived.” The teeth restored with composite were 90. The teeth restored with GIC were 14. The teeth restored with silver amalgam were 44. Out of 148 teeth were considered successful during the observation time of 3 years because no intervention was needed in these teeth were labeled as “survived.” Follow-up was done at regular intervals after 5, 7, and 10 years, respectively. At the end of 10 years, the number of teeth survived was 26. The teeth restored with composite were 14. The teeth restored with GIC were 4. The teeth restored with silver amalgam were 8. Results: At the end of the observation time period (10 years), 13 teeth had to be extracted at the end of 6 years and 19 restorations were repaired or replaced at 5, 7, and 9 years. Conclusion: Within the limitations of this study, the amount of remaining tooth structure and types of restorative material have a significant association with the longevity of endodontically treated molars without crown coverage. ETTs evaluated after 10 years showed positive survival and success in long time period. Various parameters were significantly seen to influence the outcome and thereby survival of teeth in the arch when no crowns were placed on ETTs.
