Towards Interdisciplinary Collaboration: Surveying Dentists' and Orthodontists' Perspectives on Orofacial Myofunctional Disorders and Therapy.

Introduction: Children with malocclusion, combined with orofacial myofunctional disorders (OMDs), show increased risk of developing orthodontic problems and needs later in life. Speech-language therapists typically provide orofacial myofunctional therapy (OMT) after referral by dentists, orthodontists or ENT specialists. Interdisciplinary treatment is often advisable to prevent relapse after orthodontic treatment. OMDs and OMT are often found to be controversial topics by dentistry professionals. This study aimed to investigate self-reported knowledge and attitudes of Flemish dentists and orthodontists towards OMDs and OMT.

Methods: A survey containing 32 items on demographics, self-reported knowledge of OMDs and OMT, attitudes towards OMDs, OMT, and its use in clinical practice, and referral behaviour was filled out by 48 general dentists (48/79, 61%) and 31 orthodontists (31/79, 39%). The impact of specialization, degree of experience and educational programme was also evaluated.

Results: Fifty-six percent of all participants (44/79) reported insufficient to non-existent knowledge of OMT. Nevertheless, the general attitude towards the use of OMT was neutral (47%, 37/79) to (very) positive (48%, 38/79). Although they found correct, evidence-based knowledge on OMDs and OMT important, the majority indicated their formal training did not provide adequate information on OMDs (52%, 41/79) and OMT (62%, 49/79). Specialization showed significant effects, as orthodontists reported themselves knowledgeable on this topic significantly more often than general dentists (p < 0.001), and generally reported a more positive stance towards OMT (p = 0.022).

Conclusion: Dentists and orthodontists indicated a general interest in the topic of OMDs and OMT, alongside an overall lack of information provided by formal education. Current findings suggest the necessity of re-evaluating current curricula on OMDs and OMT.
