Prevention‐oriented practice of Iranian senior dental students

OBJECTIVES: To investigate self-reported preventive practice of Iranian senior dental students in dental caries management. SUBJECTS AND METHODS: To obtain an estimated sample size of 250 subjects, seven state dental schools were selected based on a stratified random sampling approach. All the senior dental students (n = 327) were asked to voluntarily fill in a self-administered pre-tested questionnaire during the spring term in 2005. In the questionnaire two hypothetical patient cases (a high-risk and a low-risk patient) were presented and the students were asked to express their conceptions on a five-point Likert scale about including each of nine given alternatives in the patients' treatment plans. The respondents' self-reported oral self-care (OSC), preventive knowledge, attitude towards prevention and self-perceived competency in giving preventive care were also assessed. Chi-squared test and logistic regression model served for statistical analyses. RESULTS: A total of 270 students filled in the questionnaire (response rate = 82%). Acquiring high scores of preventive practice as assessed by patient cases was found to be more frequent among those reporting recommended OSC (P = 0.007) and those with higher attitude scores (P < 0.001). Also, those reporting being competent in giving preventive care had higher scores of preventive practice compared with the others (P = 0.02). In the regression model, recommended OSC (P = 0.05, OR = 1.9) and positive attitudes towards preventive dentistry (P = 0.001, OR = 3.3) showed significant association with acquiring highest scores of preventive practice. CONCLUSION: To improve their preventive practice in the future, more emphasis should be placed on the dental students' own oral health behaviour and attitudes related to it.
