Evaluation of knowledge, attitude and self-reported practice of final year dental students regarding preventive care and caries risk assessment in the comprehensive care clinic

Background and Aims: Supporting the preventive approach is important in training future dentists. The purpose of the present study was to evaluate the knowledge, attitude and practice of senior dental students regarding non-invasive management of dental caries. Materials and Methods: A cross-sectional study was conducted in 2019 using total sampling method and a valid and reliable questionnaire. Knowledge, attitude and self-reported practice of senior dental students regarding caries risk assessment (CRA) and management of lesions in two paper patients were assessed. The data analysis was performed using SPSS20 and the descriptive and analytical statistics were reported. Results: In overall, 86 students (response rate=91%) were responded. In the knowledge section, caries history in the previous year, having frequent fermentable carbohydrate, xerostomia, and low socio-economic status were considered by more than half of students as factor for caries risk assessment. More than 90% of students had a positive attitude towards CRA in children. Nearly 50% of students tend to restore enamel lesions in proximal and occlusal surfaces in high-risk scenarios. There was significant association between the OHI instruction and debris index improvement (P=0.04) in the integrated comprehensive care clinic (TUMS). The linear regression analysis showed that there was no significant association between the demographic characteristics, place of education, previous course on the level of knowledge and attitude. Conclusion: Senior dental students despite their general knowledge and positive attitude toward caries risk assessment, tended to aggressively manage the incipient lesions in the enamel and DEJ. Delivering prevention as integrated in the comprehensive care unit in order to improve oral hygiene status of patients is recommended.
