Abstract: (188 Views)
Introduction: Platelet-Rich Fibrin (PRF) is an autologous biomaterial widely used in regenerative dentistry due to its biocompatibility and ability to promote tissue healing. Despite its clinical relevance, the level of knowledge among dental students regarding PRF remains underexplored. This study aimed to assess the knowledge of dental students at Guilan University of Medical Sciences about PRF and its clinical applications.
Materials and Methods: An analytical cross-sectional study was conducted during the 2023–2024 academic year among 105 fifth- and sixth-year dental students selected through stratified sampling. Data were collected using a researcher-developed, validated questionnaire (Cronbach's alpha = 0.94, ICC = 0.96) distributed electronically. The survey assessed demographic characteristics, familiarity with PRF, and knowledge of its composition, safety, cost, and clinical uses. The ShapiroWilk test, independent-samples t test, and Pearson correlation analysis were used for data analysis. P < 0.05 was considered statistically significant.
Results: The mean age of participants was 25.18 ± 1.70 years. Overall, 39% of students were familiar with PRF, but knowledge regarding its clinical applications, safety, and cost was limited. The mean knowledge score was 2.89 ± 2.59 (range: 0–9). A significant positive correlation was found between age and knowledge scores (P = 0.004, r = 0.28), and sixth-year students scored significantly higher than fifth-year students (P = 0.016). No significant gender difference was observed.
Conclusions: The findings highlight substantial educational gaps in PRF knowledge among dental students, suggesting the need for curriculum reforms and targeted training to enhance clinical readiness in regenerative dentistry.
