This cross sectional type of descriptive study was conducted among the students of a Dental College, Rajshahi, Bangladesh with a view to estimate the proportion of dental plaque associated with oral hygiene. A total of 300 students were interviewed and examined which were selected purposively. The respondents were selected purposively. Data were collected from the respondents by face to face interview according to a partially structured questionnaire. The mean age of the respondents was 20.97 (SD ± 1.76) years. Majority of the respondents (96.7%) were under graduate students. The average monthly income of the family was BDT 24293.33 (SD ± 6809.44). Most of the respondents (60.7%) brushed their teeth twice a day and 72% of them brushed up and down and both surface of the teeth. About 88% used tooth paste and 96.3% used tooth brush. Among the respondents, 40.3% had no plaque, 43.7% had separate flecks at the cervical margin, 15.7% had plaque up to 1 mm and 0.3% had plaque wider than 1 mm. In this study dental plaque had significant relationship with monthly family income (p < 0.05), residence (p < 0.001), frequency of tooth brushing (p < 0.001), technique of tooth brushing (p < 0.001), materials used for tooth brushing (p < 0.001) and chewing habit (p < 0.05). This study provided some important information which might help the concerned people to take appropriate measures and might be the basis for further in-depth study on this issue. 7. Javed F., et al.
