Background and Aim: Botulinum neurotoxin (BoNT) has gained increasing importance in dental practice for both therapeutic and aesthetic applications. However, its safe and effective use requires adequate knowledge and training. This study aimed to evaluate the knowledge, attitudes, and clinical intentions regarding the use of BoNT among dental students. Materials and Methods: This cross-sectional study was conducted using an online, self-administered questionnaire distributed to dental students at two foundation universities in Turkey. The questionnaire assessed demographic characteristics, knowledge of BoNT (definition, indications, contraindications, and adverse effects), and attitudes toward its clinical use. Data were analyzed using descriptive statistics and Chi-square tests, with statistical significance set at p < 0.05. Results: A total of 506 students participated. Only 34.4% of students correctly identified BoNT as a toxin, and 18.6% correctly identified all clinical indications of BoNT. Knowledge regarding contraindications was particularly limited, with only 2.8% answering correctly. Despite these gaps, 76.7% of students reported willingness to use BoNT in clinical practice, and 77.1% expressed interest in attending training courses. Students who expressed willingness to undergo BoNT injections themselves were significantly more likely to report willingness to administer BoNT clinically (p < 0.05). No consistent increase in knowledge levels was observed across academic years. Conclusion: Dental students demonstrated limited knowledge of BoNT despite a high level of interest in its potential clinical use. These findings provide preliminary information regarding undergraduate dental students' awareness and perceptions of BoNT.
