Epidemiological Study of Patient With Dentofacial Deformities Treated at San Borja Arriaran Clinical Hospital, Santiago, Chile
Dentofacial deformity is described as a type of deformity that affects primarily the jaws and dentition, and its prevalence is variable, depending on genetic and social factors. Studies of the prevalence of deformities are not very common; most of them have strictly the evaluation of occlusal problems as their final purpose, without major intents concerning skeletal structure and facial patterns (1-2). The purpose of the present study was to retrospectively analyze patients with dentofacial deformities treated from 1997 to 2013 in San Borja Arriarán Cinical Hospital in Santiago de Chile, Chile.
Material and methods
The medical records of 456 patients who were treated from 1997 to 2013 at were analyzed. The exclusion criteria were as follows: patients presenting syndromes and labiopalatal clefts; in addition, incomplete records were excluded from the study. The statistical analysis was performed with the chi-squared analysis.
Results
The prevalence of dentofacial deformities of patients who were treated in the Hospital was greater in women (65.4%) than men (34.5%). As for skeletal pattern, class III was the most incident (71.1%), followed by class II (28.9%). 55.9% of the patients who received treatment were between 20-29 years old, 29.8% were younger than 20 and 14.3% were older than 30.
Conclusions:
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.
