Investigation of the relationship of the maxillary sinus floor with maxillary posterior teeth using cone beam CT.

Given the proximity of these structures, this study aimed to investigate the relationship between the maxillary sinus (MS) and MPT. Materials and methods: CBCT images obtained from 207 patients (mean age, 45 ± 17 years; age range: 18–92 years) including 99 females and 108 males were examined retrospectively. Patients with sinus pathologies affecting the structure of MS and a history of oral and maxillofacial surgery were excluded from the study. On these images, the relationship of maxillary sinus floor (MSF) with 2 premolars and 3 molars was examined bilaterally for each patient using Kwak H. H. et al.’s classification. The presence, number, frequency and location of septa within the MSF were investigated. Results: Examination of a total of 410 maxillary sinuses on the images of 207 patients with no sinus perforation or pathology revealed that septa were most commonly (48.7%) located in the middle segment (second molars). When the relationship between the MSF and MPT was evaluated, molar teeth were found to have a closer relationship with the MSF than premolars. 1 Conclusions: It is believed that the findings of this study may provide further guidance to the dental practitioners and other clinicians for future studies.eninfo:eu-repo/semantics/openAccessMaxillary SinusMaxillary Sinus SeptaMaxillary Posterior TeethCone-Beam Computed TomographyMorphometryArticleQ3PMID: 38757496Q2
