Objective : To evaluate the prevalence of oral mucosal lesions of Thai elderly dental patients and to determine its association with
age, gender, medical conditions, oral habits, and denture wearing.
Materials and Methods : Two hundred eleven patients who were 60-years-old or older and attended Dental Hospital, Naresuan
University, Thailand participated in the present study. The prevalence of oral mucosal lesions as well as the medico-demographic
data were collected. Intraoral examination and diagnosis were done according to the World Health Organization Guideline. The
association and the correlation between variables were analyzed using Pearson’s Chi-square test.
Results : The overall prevalence of oral mucosal lesions was 61.6%. There was no statistically signi(cid:976)icant difference between age
groups, genders, medical conditions, smoking, alcoholic beverage consumption, areca nut chewing, and denture wearing. The three
most common lesions were traumatic ulcer (12.8%), frictional keratosis (10.9%), and melanotic macule (9.5%).
Conclusion : Thai elderly dental patient group in Thailand has slightly high prevalence of oral mucosal lesions. Age, gender, medical
conditions, oral habits, and denture wearing are not associated with overall prevalence, but speci(cid:976)ically associated with some
individual lesions.
