Relación de la comunicación bucosinusal con la exodoncia de molares superiores extraídos en la clínica odontológica de la Universidad Católica Santiago de Guayaquil.

Abstract

Introduction: The Oro-antral communication (OAC) has been reported as the most frequent complications treated in upper molar extractions. Its a pathology characterized by the loss of bone continuity between the alveolar bone and the maxillary sinus’s mucous membrane. Objective: Determine the relationship between oro-antral communication and the extraction of upper molars in the UCSG dental clinic. Materials and Methods: The sample selection consists of a universe of 423 extractions. After applying inclusion and exclusion criteria, a sample of 167 extractions remained. These aspects were considered in data collection: preoperative, diagnostic imaging, transoperative, postoperative. Results: 88.62% (148 cases) presented a negative Valsalva test, while 11.38% (19 cases) were positive. In addition, within the 19 cases mentioned, it should be noted that 63.16% (12 cases) were female, while 36.84% (7 cases) belonged to the male gender. The most frequently piece extracted from CBS was piece 28 with 36.84%, followed by piece 16 with 26.32% and, in third place, piece 18 with 21.05%. Conclusion: The results of the study are very similar to the analized literature based on pathologies associated with CBS, treatment methods and the importance of diagnosis, however, they disagree with the incidence of the affected piece.
