Abstract

Objectives: This study aimed to relate the presence of mucosal thickening in the floor of maxillary sinuses with periapical lesions in endodontically-treated posterior teeth, regarding sex, age, element and dental root. Materials and methods: The study consisted of 50 samples of cone beam computed tomography (CBCT), and 74 dental elements. The analyses were performed from axial and coronal sections in the i-CAT® Vision software, and the images were classified into four groups: G1: lesions with diffuse characteristics; G2: lesions with circumscribed characteristics; G3: lesions of cystic characteristics and G4: mucosal thickening of the floor of the maxillary sinuses. The distribution according to sex, the presence of mucosal thickening and of periapical lesions were submitted to the Chi-square test or Fisher’s exact test when necessary. The age of the patients concerning the presence of mucosal thickening was analyzed by the Mann-Whitney test and, regarding periapical lesions, it was analyzed by the Kruskal-Wallis and Dunn tests. Results: There were no statistically significant differences (Chi-square, p = 0.5279) between genders, considering the dental elements observed in the study, neither , between periapical lesions and age (Kruskal-Wallis, p = 0.7836). The palatine root was the one that was most involved with periapical lesions and/or mucosal thickening (55.8%). The lesions with diffuse characteristics (47.3%) were more common than the others. Conclusions: There was no relationship between mucosal thickening and periapical lesions, and vice versa (Fisher exact test, p = 0.0678).
