Prevalence and treatment of dentofacial deformities on a multiethnic population: a retrospective study

The purpose of the present study was to retrospectively analyze patients with dentofacial deformities attending a reference center in a Brazilian educational institution who sought orthosurgical treatment.

The medical records of 251 patients who sought treatment from 2003 to 2011 at Piracicaba Dental School, State University of Campinas (Unicamp) were analyzed. The exclusion criteria were as follows: patients presenting syndromes and labiopalatal clefts; in addition, incomplete records were excluded from the study.

The prevalence of dentofacial deformities was greater in women (60.93 %), as well as leukoderma patients (69.22 %). The main motivation for treatment was functional (52 %), followed by esthetics (27 %). As for skeletal pattern, class III was the most incident (55 %), followed by class II (29.5 %) and class I (15.5 %). Regarding the type of deformity, class I patients had predominantly maxillary atresia (53 %). In the case of class II patients, the main deformity was anteroposterior mandibular deficiency (89 %), and in class III, anteroposterior maxillary deficiency (51 %).

The results of the present study suggest that the profile of patients bearing dentofacial deformities in this population is composed of mostly young women motivated by functional issues, and class III skeletal deformity is the most common.
