Estudo da ocorrência de recidivas após enucleação, seguida de ostectomia periférica e solução de carnoy no tratamento das lesões odontogênicas benignas agressivas

Abstract

Retrospective sectional study with the objective of investigating the occurrence of relapses in aggressive benign odontogenic lesions after the surgical enucleation protocol, followed by peripheral ostectomy and Carnoy's solution. The sample used was of convenience and consisted of thirty patients attended in Oral and Maxillofacial Surgery Department of UFRN between 2008 and 2018. The data were collected through the medical records and then the patients were contacted to perform of clinical and radiographic exams in order to verify the presence of relapses. Descriptive and statistical analyzes were performed using the Stata / IC version 14.0 program (StataCorp, College Station, TX). The Mann-Whitney test, the Fisher's exact test and the Chi-square test, as well as the Kaplan Meier method and the Log-rank test were used to verify the possible prognostic factors for relapses, using p <0 , 05. The sample consisted of 12 male patients (40%) and eighteen female patients (60%) and the mean age was 37.23 years (37.23 ± 17.01, 12-77). Among the lesions, 22 patients had CO (73.3%), 3 MO (10%) and 5 ameloblastomas (16.7%). Most of the lesions affected the posterior maxilla and mandible (93.3%). The relapse affected 7 patients (23.3%), all cases in OC, with a minimum recurrence time of 12 months and a maximum of 34 months and a maximum follow-up of 9 years and 5 months. There was no statistical difference between the factors evaluated and the development of relapses, but patients who remained with adjacent teeth after the surgical procedure presented less recurrence time. Kaplan-Meier curves showed a cumulative risk of more than 80% for recurrence after 29 months postoperatively and after 36 months of followup, only 37.50% of these patients would be free of relapses (p = 0.023), in addition this group were 5.5 times more likely to develop recurrences than patients who had their teeth extracted. The protocol is effective in the treatment of benign aggressive odontogenic lesions when compared to isolated treatments, such as marsupialization and enucleation/curettage, considering the same lesions.
