Researchers carefully assessed and recorded participants' oral health status using the OHI-S criteria. The findings revealed interesting results: Dental students excelled in the plaque index, followed by nursing and operating room students. In terms of the calculus index, nursing students led, followed by dental and operating room students. Statistical analysis indicated a significant association between the field of study and the OHI-S index. Dental students achieved higher scores compared to their peers. Additionally, there was a notable relationship between gender and oral health behaviors, with females demonstrating better practices than males. In conclusion, the study highlights the impact of education on improving oral health habits. Dental students' specialized knowledge contributed to their superior oral hygiene routines. These findings can be valuable in promoting oral health awareness among various medical student groups.
