Maxillary Sinus Floor and Maxillary Posterior Teeth: A Biometric Assessment using Cone Beam Computed Tomography in a Tunisian Population
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2017, Vol 5, Issue 12
Abstract
Abstract: The aim ofthis study to assess the vertical relationship between the maxillary sinus floor (MSF) and maxillary posterior teeth (MPT) roots using cone beam computed tomography in a Tunisian population. In this cross-sectional study, CBCT of 60 patients were selected including 33 males and 27 females. Totally 100 Maxillary sinuses were analyzed; enclosing 500 MPT i.e 1256 root tips. The vertical relationship between each root of the MPT and the MSF was classified into three types: type 1; the roots were in contact with the MSF, type 2; the roots penetrated into the MSF and type 3; the roots were distant from the MSF. For the vertical relationships according to the maxillary teeth, type 3 occurred most frequently in the first premolar (94%). Type 2 was most frequently observed with the second molar (32%). For the vertical relationships according to the each root of these teeth and the MSF, the results were as follow: Type 3 occurred most frequently in the first premolar buccal root (98%). For the type 2, the mesio-buccal root of the second molar had the closest proximity with the MSF with 48%. No statistically significant difference was found between the right and left side assessments but several differences were found between males and females. This relationship between MPT and MSF should be considered in order to prevent an iatrogenic procedure and minimize the risks from an infectious disease within the sinus. Keywords:Premolars; Molars; Maxillary sinus; Cone-beam computed tomography.
