Abstract

Aim: The present study aimed to evaluate the anatomical relationship between the maxillary sinus (MS) floor and the root apices of maxillary posterior teeth in the Egyptian population using panoramic radiograph evaluation. Materials and methods: Radiographic images of 208 patients obtained from the archives of the Department of Oral and Maxillofacial Radiology at the British University in Egypt were analyzed by an oral and maxillofacial radiology specialist to determine the distance between the deepest point of the MS floor and the root tips of the maxillary first and second premolars and first, second, and third molars using PDI-Viewer Version 2.20 R03 (Konica Minolta Inc., Tokyo, Japan). Data were recorded and statistically analyzed using Statistical Package for the Social Sciences (SPSS) Statistics, version 26 (IBM Corp., Armonk, New York, United States). Results: The measurements of the distance between the floor of the MS and root apices were variable among different teeth, with the first premolar showing the furthest relationship and the palatal roots of the upper first and second molars showing the closest. This distance decreased with age but showed no difference between the right and left sides of the same patient. Conclusion: The anatomical relationship between the MS floor and the maxillary posterior teeth is variable among different ages and genders, so it must be determined before adopting dental treatment. Clinical significance: Many clinical procedures depend on the routine panoramic X-ray; the hassle of upper teeth extraction and its complications are a major concern for dentists. The clinical significance of the current study is to provide guidance to clinicians during different dental procedures.
