Introduction: Endodontically treated teeth which have extensive structural defects due to caries, access cavity preparation require post and core management for retention purpose.The clinical decision is to decide whether an endodontically treated tooth requires a post and a crown poses a challenge to dental practitioners. Aim; The study aims at analysing remaining coronal tooth structure in relation with prefabricated metal posts in molars. Materials and Method: This retrospective clinical study evaluated the patients who received prefabricated metal posts in endodontically treated molars from the department of Conservative Dentistry and Endodontics in a dental college located at Chennai. Total of 373 patient’s records were evaluated from June 2019 to March 2020 and based on inclusion and exclusion criteria, selected data consisted of 219 patients who received prefabricated metal posts in endodontically treated molars.Inclusion criteria consisted of patients aged between 18-60 years who received prefabricated metal posts in endodontically treated molars. Exclusion criteria consisted of patients who received FRC and cast post in endodontically treated teeth other than molars. Results; In this study of 219 patients (104 are females,115 are males with a mean age group of 30 years) were included.It is observed that there is a significant difference among the groups. Group B (coronal tooth structure- 2 to 4 mm) were highly noted in endodontically treated molars with prefabricated metal posts compared to other groups with p value<0.05 . Conclusion : The clinical analysis in relation to endodontically treated molars with prefabricated metal posts showed the remaining coronal tooth structure of 2-4 mm was highly noted although it’s not statistically significant. 2-4mm of remaining coronal tooth structure is essential for preventing root fracture, post dislodgement and fracture.
