To investigate self-reported preventive practice of Iranian senior dental students in dental caries management.
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.
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.
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.
调查伊朗高年级牙科学生在龋齿管理方面自我报告的预防措施。
为获得估计250名受试者的样本量，采用分层随机抽样方法选择了7所国立牙科学校。所有高年级牙科学生（n = 327）被要求在2005年春季学期自愿填写一份预先测试过的自填式问卷。问卷中呈现了两个假设的患者病例（一个高风险患者和一个低风险患者），并要求学生用五点李克特量表表达他们对在患者治疗计划中纳入九个给定选项中每一个的看法。还评估了受访者自我报告的口腔自我护理（OSC）、预防知识、对预防的态度以及在提供预防护理方面的自我感知能力。采用卡方检验和逻辑回归模型进行统计分析。
共有270名学生填写了问卷（回复率 = 82%）。在报告推荐的OSC的学生（P = 0.007）和态度得分较高的学生（P < 0.001）中，通过患者病例评估获得高预防措施得分的情况更为常见。此外，报告有能力提供预防护理的学生与其他学生相比，预防措施得分更高（P = 0.02）。在回归模型中，推荐的OSC（P = 0.05，OR = 1.9）和对预防牙科的积极态度（P = 0.001，OR = 3.）与获得最高预防措施得分显示出显著关联。
为了在未来提高他们的预防措施，应更加重视牙科学生自身的口腔健康行为及其相关态度。
