Main facial anatomical concerns of dentists to perform botox injections

The increasing demand for minimally invasive aesthetic procedures, particularly botulinum toxin type A (BTX-A) injections, has expanded the scope of dental practice to include facial aesthetics. However, the safe and effective administration of BTX-A requires a thorough understanding of facial anatomy, including the topographic relationships of muscles, skin layers, and vascular structures. This cross-sectional study aimed to identify the primary anatomical concerns and knowledge gaps among dentists performing BTX-A injections.

A structured questionnaire was distributed to 316 dentists, assessing their confidence and knowledge regarding facial anatomy and BTX-A application.

A total of 62% of participants had specialized training, while 37% had attended BTX-A-specific courses. Notably, professionals with specialized training demonstrated significantly greater confidence and anatomical knowledge compared to their non-specialized counterparts. Key areas of concern included the corrugator supercilii, levator labii superioris alaeque nasi, orbicularis oculi, frontalis, and platysma muscles, as well as the facial artery's location and depth. Over 80% of respondents reported limited or insufficient knowledge in these areas, highlighting a critical need for enhanced anatomical education and practical training.

The study underscores the importance of integrating facial anatomy and injection techniques into dental curricula and continuing education programs to ensure patient safety and optimize treatment outcomes. By addressing these knowledge gaps, dentists can confidently expand their practice to include BTX-A applications, contributing to the growing field of orofacial harmonization.
