Abstract

Introduction: Aim of the study was to assess the relationship between maxillary sinus floor and maxillary posterior teeth. Materials and Methods: Retrospectively 50 cone beam computed tomographic images in the age group of 20 to 60 years were procured from CBCT archives randomly, based on the inclusion and exclusion criteria set forth for the study. Results: Palatal root of right maxillary 1st premolar was farthest & mesiobuccal root of maxillary right 2nd molar was nearest to maxillary sinus (MS). Mean thickness of the distobuccal root for left maxillary 2nd molar with buccal cortical was maximum whereas mean thickness for the mesiobuccal root with buccal cortical plate for left maxillary 1st molar was minimum. Conclusion: Adequate radiographic investigations are required before any surgical procedure in maxillary posterior teeth region. We recommend to use CBCT a 3-dimensional imaging modality when required. Keywords: Cone beam computed tomography (CBCT), Maxillary posterior teeth, Maxillary sinus floor (MSF).

Abstract

Introduction: Determination of gender is an important aspect of forensic odontology. CBCT measurement of maxillary sinuses can be useful in determination of gender. Aim: To assess the sexual dimorphism using dimensions of maxillary sinus in CBCT images. Objectives: 1) To determine whether there are morphological and morphometric variations among genders. 2) To assess which the most reliable predictor of sex among width, length & height. Materials and Method: The present study was conducted in Department of Oral Medicine and Radiology. Retrospectively 40 CBCT scans of bilateral maxillary sinus were retrieved from the database after excluding the subjects with pathologies of maxillary sinus like cyst, tumours and fractures and images with errors or artefacts obscuring maxillary sinus. Two independent observer measured three distances of the maxillary sinus (width, length, height) in axial and coronal view. Results: Parameters of Maxillary Sinus for male were greater than females. Width and height was better predictor than length with 60% accuracy than 50% accuracy for length. Conclusion: We suggest that CBCT measurement of Maxillary Sinus can be used as supplementary tool for gender determination in forensic science.
