Thirty-two patients with burning mouth syndrome and 32 matched control subjects 
were evaluated for their personality profile using a comprehensive, reliable, 
and validated inventory. All subjects were requested to complete the Neo PI-R 
questionnaire that measures the 5 dimensions of personality and their facets. A 
t-test and univariate correlations (Pearson's correlation coefficient) were used 
to compare the 2 groups. Results show high significant differences in some 
personality factors. Neuroticism and all its facets, which include anxiety, 
angry hostility, depression, self-consciousness, impulsiveness and 
vulnerability, were significant at P<.001. Other domains like extraversion, 
openness, and conscientiousness showed significant differences also (P<.05). 
Many personality characteristics differentiate burning mouth syndrome patients 
from controllers according to the Neo PI-R and this should affect the treatment 
plan according to the identified characteristics.
