Abstract
This report describes a questionnaire-based study on 309 adult patients attending the Dental Outpatients
Department of Bangladesh Medical College and Hospital, Dhaka during December 2000 to March 2001. The
aim of the study was to determine the oral health knowledge of the patients in relation to their age, gender,
economic and educational status. Almost two third (63.1%) of the subjects correctly said that pan chewing was
bad for teeth. Three fourth (78.3%) of the subjects gave correct answer on question of how to prevent teeth
decay. When question was asked about cause of teeth decay, bleeding gum and action of fluoride on teeth, only
38.2%, 41.4% and 32.3% could give correct answer respectively. With a few exceptions, knowledge of oral
health was comparatively poor among the older generation, females, less educated and less privileged group.
