Background: In the past, there have been several studies which have evaluated the relation between the proximity of the molars to maxillary sinus and its influence over the success of the endodontic surgery in that region. However, all that studies used two-dimensional radiographic techniques for evaluation. There are certain limitations of these two-dimensional radiographic techniques such as shortening, elongation, and superimposition of images. Recently, three-dimensional technique like cone-beam computed tomography (CBCT) has been introduced in which these disadvantages have been eliminated. Aim: Analysis of the anatomical relation of the maxillary molars with maxillary sinus and its influence over success of the endodontic surgery in the maxillary posterior region using CBCT. Materials and Methods: Patients who underwent a microsurgical endodontic surgery on their upper molar teeth between 2018 and 2020 were included in this retrospective analysis. The study enlisted the participation of 42 patients. Only those patients with a CBCT radiographic image were included in the study. The proximity of the root of maxillary molar teeth to the membrane of the maxillary sinus, as well as periapical disease, was assessed both clinically and radiographically using CBCT. Results: It was observed in this study that the overall success rate of the periapical endodontic surgical process was 89.3%. In this study, a total of 42 patients were evaluated. Overall, 31 roots and 31 canals were managed endodontically. It was observed at follow-up of 12 months that 89.3% of patients showed successful results with the endodontic surgery irrespective of the level of proximity of the root and periapical lesion with the maxillary sinus. Conclusion: Within the limitations of this study, it can be concluded that success of the endodontic surgery is not affected by the level of proximity of the root of maxillary molar and periapical pathology with the membrane of the maxillary sinus but on the condition when it is performed by the skilled and experienced clinician and there is proper pre-operative radiographic assessment using CBCT.
