Comparison of Oral Hygiene Levels and Behaviors Between First and Final Year Dental Students in Jordan

Background: Achieving and maintaining good oral hygiene is essential for gingival health. However, oral hygiene attitudes and behaviors may vary according to knowledge, beliefs, and education. Objective: To compare and quantify discrepancies in oral health attitudes and self-care levels between first and final year dental students. Methodology: Two hundred and seventy seven dental students at the University of Jordan were recruited in this study. The sample involved 162 first year and 115 final year students with age ranges of 18-19 and 21-22 years, respectively. Subjects were asked to fill a structured questionnaire about their oral hygiene habits. Clinical examinations were performed at the Periodontal Department of Jordan University Hospital. Oral hygiene levels were clinically assessed by the plaque index (PI) and gingival index (GI). Results: Analysis showed that final year students brushed their teeth, flossed, and maintained regular dental visits. They also brushed their teeth twice more frequently and changed the brush more often per year. However, both first and final year students used mouthwash almost equally. Final year students also have less bacterial plaque and suffered less gingival inflammation in prevalence and severity. Conclusion: It was concluded that final year dental students have a significantly better gingival status than first year students.
