Avaliação da relação de diversas condições dentárias com a presença de sinusite maxilar crônica uni ou bilateral: estudo por tomografia computadorizada de feixe cônico

Abstract

The anatomical relationship of the maxillary sinus (MS) involves the maxillary dental roots, explaining the easy extension of infectious processes from some teeth to the sinus. This study aims to correlate odontogenic causes to the presence of uni- or bilateral maxillary sinusitis in cone beam computed tomography images. For this study, 41 patients from the Otorhinolaryngology Clinic of the University Hospital, diagnosed with chronic maxillary sinusitis, were included and divided in two groups: BMS: patients with bilateral maxillary sinusitis; UMS: patients with unilateral maxillary sinusitis. Different dental conditions were considered in both groups, like distance from apex root to the sinus, periapical radiolucency and alveolar bone loss. Data were analyzed with Chi Square and Fisher Exact tests. The confidence interval was 95% (P ≤ .05). No statistical difference was observed between uni- or bilateral maxillary sinusitis with the proximity of the teeth to the MS; presence of periapical radiolucency and alveolar bone loss (p>.05). In this study, odontogenic causes are present in uni- and bilateral maxillary sinusitis cases and the molars showed closer relationship to the MS in the UMS group, although without significant association.
