Comparison of the personality characteristics of males and females with jaw deformities using the MINI automatic psychology analysis system

Abstract

We examined how jaw deformities affected personality in males and females using the MINI psychology analysis method Ver 6.0 with patients who visited the Orthodontic Department of Osaka Dental University between 1999 to 2002. We studied 19 males between the ages of 18 and 27 years with a median are of 22, and 27 females between the ages of 18 and 39 years with a median age of 23. The results for the two genders were compared. Males had siginificantly higher scores than people without jaw deformities for Hy (hysteria), Pd (psychopathic deviation), and Pa (paranoia). However, no siginificant difference were observed in the females. We concluded the jaw deformity might be associated with mental disorder in males.
