EVALUATING THE RELATIONSHIP BETWEEN MAXILLARY MOLAR ROOTS AND MAXILLARY SINUS FLOOR – A RETROSPECTIVE STUDY USING CONE-BEAM COMPUTERIZED TOMOGRAPHY
Journal Title: International Journal of Medical Science and Diagnosis Research (IJMSDR) - Year 2018, Vol 2, Issue 5
Abstract
Objectives: The aim of the present study was to assess the relationship between the maxillary sinus floor and the maxillary molar root tips using CBCT. The relation of maxillary posterior teeth roots to the maxillary sinus floor is important for diagnosing and planning of many surgical procedures. Methods: A total of 45 maxillary first molars and 45 maxillary second molars from 50 patients were examined with CBCT. For each root the shortest distance to the maxillary sinus was determined in sagittal, coronal and axial planes, using in-built measurement tools. Means, standard deviations, minimum and maximum values and frequency of root protrusion were calculated for all roots. Results: The distance between sinus floor and root tip was longest for the first molar mesiobuccal root and shortest for the second molar distobuccal root. Conclusions: Knowledge of the anatomical relationship between the maxillary sinus floor and the maxillary posterior teeth root tips is important for the preoperative treatment planning of maxillary posterior teeth. Keywords: CBCT, Maxillary molar roots, Maxillary sinus, Endodontic implications
