KNOWLEDGE OF THE CONCEPTS OF FUNCTIONAL JAW ORTHOPEDICS AMONG ORTHODONTISTS AND PEDIATRIC DENTISTS IN BRAZIL

Abstract

Objective: To evaluate the knowledge of Functional Jaw Orthopedics (FJO) concepts among Orthodontists and Pediatric Dentists in Brazil. Materials and Methods: A cross-sectional, observational, and descriptive study conducted with 605 specialists recruited via social media, referrals, and professional associations. A structured online questionnaire with five objective questions regarding fundamentals, principles, natural forces, neural excitation, and periodontal ligament receptors was applied. Data were analyzed using JASP software via the chi-square test (p < 0.05). Results: Overall knowledge to understand FJO was declared by 72.5% of participants, and 60.3% stated knowing its fundamental principles. However, declared knowledge regarding natural forces (48%), neural excitation (43.7%), and periodontal receptors (44%) was below 50%. Orthodontists showed significantly higher proportions of affirmative responses than Pediatric Dentists in these topics (p < 0.05). No significant association was found between specialty and geographic region. Discussion: A pattern of decreasing affirmative responses was observed as concepts became more specific. This variation highlights a significant gap between self-perceived general knowledge and the actual mastery of essential physiological and neurofunctional aspects of FJO. Conclusion: Findings highlight the need to improve academic education and continuing education, strengthening evidence-based clinical practice.
