Abstract

Background: Senior dental students are more aware of the harmful effects of cariogenic snacks and are expected to better watch their diet compared with freshmen dental students. This study aimed to compare the frequency of consumption of cariogenic snacks by senior and freshmen dental students of Tehran city and the related factors.

Methods: This cross-sectional study evaluated the senior and freshmen dental students attending dental schools in Tehran in 2018, who were selected by census sampling. A cariogenic snack record form was used to collect information regarding the frequency of consumption of cariogenic snacks both prospectively (within the upcoming week) and retrospectively (previous 24 hours). We also collected information on the demographic characteristics of the participants. The plaque-producing and decay-producing potential of the diet (PAP) index was calculated for each dental student. Data were analysed by the backward regression model using SPSS.

Results: A total of 294 dental students with a mean age of 22±2.85 years participated in this study. The mean PAP score was 76.48±49.91 for the freshmen and 89.87±49.41 for the senior dental students with a significant difference between them (p=0.023). Older dental students (p=0.008) and those not living with their parents (p=0.001) acquired a higher PAP score.

Conclusion: The mean PAP score of freshmen and senior dental students in Tehran was slightly higher than the optimal level. So the instructional techniques of dental curricula are better to be revised to improve the performance of dental students to cut down the consumption of cariogenic snacks.
