OLAECHEA-RAMOS, Maria Alejandra; EVANGELISTA-ALVA, Alexis  and  QUEZADA-MARQUEZ, Milushka Miroslava. Radiographics characteristics of dentigerous cysts diagnosed in the Universidad Peruana Cayetano Heredia. Rev. Estomatol. Herediana [online]. 2019, vol.29, n.1, pp.49-61. ISSN 1019-4355.

Objective: To evaluate the x-rays characteristics of dentigerous cysts diagnosed in the Universidad Peruana Cayetano Heredia between 2010 and 2017. Material and Methods: Retrospective, descriptive, observational, and transversal study based on selected panoramic x-rays of dentigerous cysts cases. Results: Only 37 out of a total sample of 237 dentigerous cysts cases were examined based on an inclusion and exclusion criteria. From this sample, 45.9 percent of cysts were found in the second decade of life with a higher frequency of 51.4 percent for women, and a jaw predilection of 59.5% in all cases. In addition, it was found that 97.3 percent of the cases were radiolucent, defined limits were found in 67.6 percent of cases, corticalized edges in 54.1 percent of cases, and unilocular in 94.6 percent of cases. All dentigerous cysts were associated with a dental piece of which 48.6 percent had a closed apex and dental displacement was observed in 59.5 percent of cases. In 56.8 percent of cases, the adjacent tooth was not affected, but its hard film was affected in 59.5 percent of cases. Moreover, 68.2 percent of the dentigerous cysts did not affect the cortex of the mandibular basal, but 54.5 percent displaced the inferior dental canal and 46.7% displaced the maxillary sinus floor. Conclusions: Most of the results obtained about characteristics in Peruvian population support previous studies reported in America, Europe and Asia. Radiographically, dentigerous cysts displayed characteristics that support their clearly benign behavior.
