Effect of 5 years of dental studies on the oral health of Tunisian dental students

This study is a follow-up of one made in 1998–99 on first-year dental students in Monastir. Now in their fifth year, we assessed the effect of dental studies on students’ oral health practices and dental health. Of the 155 students in the first study, 140 were still enrolled. Periodontal troubles, maloccclusion and dental decay affected 84.3%, 80.0% and 43.0% of the students respectively. Compared with the previous study, students had achieved a better dental health status – tooth brushing rate was much higher, prevalence of dental decay and periodontal pockets had decreased, and DMF index had improved. However, the prevalence of smoking, bleeding and calculus had not changed, and the freqquency of malocclusion had increased.
