The maintenance of good oral hygiene is considered a salient issue in dental health promotion. Personality is the combination of characteristics or qualities that form an individual's distinctive character. Various personality traits have been proposed to influence the oral health. The purpose of the present study was to assess the influence of personality characteristics using questionnaire on oral hygiene performance and gingival health.


In total, 155 patients were subjected to personality questionnaire using Eysenck Personality Questionnaire. Clinical parameters such as Patient oral hygiene performance index and gingival index were recorded. Based on Eysenck Personality Questionnaire, the subjects were divided into three groups: Psychoticism, extroversion, and neuroticism.


Data analysis showed that subjects in psychoticism and neuroticism groups displayed moderate gingivitis, whereas subjects in extroversion group had severe gingivitis. Subjects in all the three groups demonstrated poor oral hygiene status. No statistically significant relation was found.


A considerable clinical correlation was observed between the different personality traits and gingival health status of the subjects. It was not statistically significant. Further trials need to be conducted so as to ascertain this association so that psychological interventions may be undertaken to improve the oral hygiene condition of the population.
