Correlação entre a sinusite crônica e alterações endoperiodontais: um estudo por tomografia computadorizada de feixe cônico e avaliação clínica

Abstract

The proximity of the roots of maxillary posterior teeth to the maxillary sinus floor can be associated with the development of chronic maxillary sinusitis (CMS). Therefore, the aim of this study was to evaluate the correlation between odontogenic endoperiodontal change conditions and the proximity of the maxillary posterior teeth to the floor of the maxillary sinus and the presence of chronic maxillary sinusitis. A total of 83 patients (159 maxillary sinuses) were selected and underwent clinical dental examination to assess tooth mobility and tooth pulp condition. In addition, cone beam computed tomography was performed to evaluate the presence of periapical lesions, periodontal bone loss and measure the distance from the root apices to the cortical of the maxillary sinus. . The maxillary sinuses were divided into two groups: GCMS- chronic maxillary sinusitis and GNMS- no maxillary sinusitis. The association between the endoperiodontal changes and the proximity with the maxillary sinus floor in relation to presence or absence of SMC was analyzed by Chisquare test (p < 0.05). Binary logistic regression was used to evaluate the factors associated with the SMC (p < 0.05). The results showed that tooth mobility was positively associated with chronic sinusitis, leading to a 3.45-fold increased association of developing the disorder (p < 0.05). GCMS is associated with teeth with endoperiodontal changes near the maxillary sinus, whereas teeth with endoperiodontal changes were more distant from the maxillary sinus in GNMS (p < 0.05). To the extent that the tooth is more distant from the maxillary sinus floor, the chance risk of presenting chronic sinusitis is reduced up to 2.5-fold (p < 0.05). In conclusion, tooth mobility and proximity to the maxillary sinus are associated with cases of chronic maxillary sinusitis, requiring better interactions between dental surgeons and an otolaryngologyspecialists in pursuit of greater effectiveness in the treatment of the disorder.
