Resumen

Introduction: Stafne’s bone cavity is a rare, radiolucent, well-demarcated anatomic variant that usually occurs in the molar region near the mandibular angle and below the canal for the inferior dental nerve. It is frequently mis-diagnosed with other pathological entities. Objective: To determine the frequency of Stafne’s bone cavity in panoramic radiographs of the Oral and Maxillofa-cial Radiology Service of the Teaching Dental Care Center “Cayetano Heredia”, from 2015 to 2019. Methods: An observational, descriptive, cross-sectio-nal and retrospective study was performed on a sample of 17875 panoramic radiographs. Demographic variables such as gender, age, location and shape were considered; subsequently tables of contents were performed for data analysis. Results: Among the 17875 patients, only 24 (0.13 %) had Stafne’s bone cavity, including 16 males and 8 females. The eighth decade of life presented the highest number of cases with 6 (0.4 %). The right posterior location ac-counted for 13 (54.17 %), the left posterior with 7 (29.17 %) and the anterior with 4 (16.67 %). The oval shape with 23 (95.83 %) and round with only 1 (4.17 %). Conclusions: The frequency of Stafne’s bone cavity was 0.13 % with male sex predilection, eighth decade of life, right posterior location and oval shape.
