Introduction: With the advancement of laser technology in dentistry, ensuring that dental professionals possess adequate knowledge and adhere to proper safety practices is essential. This study aimed to assess the awareness of final-year dental students at Guilan University of Medical Sciences regarding the use of lasers in dentistry. Materials and Methods: This analytical cross-sectional study was conducted in 2024 and included 78 final-year dental students. Data were collected using a structured and validated questionnaire (content validity index = 0.98, content validity ratio = 1.0, Cronbach’s alpha = 0.79) comprising three sections: demographic information (age, gender, GPA [Grade Point Average]), general questions (3 items), and clinical awareness (17 items). Each correct response was scored as 1 and incorrect or unanswered items as 0, yielding a total score range of 0–17. Awareness levels were categorized as poor (0–6), moderate (7–12), and good (13–17). Data were statistically analyzed (α=0.05). Results: Of the participants, 46.2% were male and 53.8% female. The mean age was 26.99 ± 2.18 years, and the average GPA was 16.08 ± 0.73. Most students (73.1%) demonstrated a moderate level of awareness, while 25.5% had poor awareness and only 6.4% showed good awareness of laser applications. No significant association was found between awareness and age (P > 0.05); however, a statistically significant relationship was observed between GPA and awareness (P = 0.011). Conclusions: The overall awareness of dental laser applications among final-year students was moderate. Students with higher academic performance exhibited significantly greater awareness levels.
