Pediatric Dentists' Practice Patterns in the Screening, Diagnosis, and Management of Temporomandibular Disorders

Pain associated with temporomandibular disorders (TMDs) is the main non-odontogenic cause of orofacial pain among youth. Pediatric dentists are often the first healthcare practitioners to perform a comprehensive oral examination in children, which should include evaluation of the temporomandibular joint, masticatory muscles, and surrounding structures for signs and/or symptoms of TMD. This study assessed pediatric dentists' practice patterns in the screening, diagnosis, and management of TMD.

A 19-item online survey was used to assess pediatric dentists' clinical practice patterns and perceived knowledge and comfort levels in the screening, diagnosis, and management of TMD. The survey was distributed in July 2024, with a one-month window open for the study. Confidence levels and perceived knowledge were compared according to years from graduation and frequency of TMD screening assessment with ANOVA or independent t-test, as appropriate. Open-ended items were analyzed thematically.

A total of 206 pediatric dentists and pediatric dentistry residents participated in this study. A share of 72.8% of respondents reported that up to 25% of their patients per week present with signs and symptoms of TMD. About one-fifth of pediatric dental providers never complete a screening history for TMD (22.1%) or a clinical assessment of TMD-related structures (21.6%). There was overall low self-perceived knowledge and confidence among pediatric dentists regarding the diagnosis, screening, and management of TMD in children and adolescents, regardless of the number of years from graduation. Respondents who reported seeing up to 50% of TMD patients reported significantly more knowledge and confidence in diagnosing pediatric TMD than those who encountered fewer TMD patients. An overwhelming majority (81.6%) indicated a need for continuing education courses and training focused on the management of TMD in pediatric patients.

Providers reported low confidence and self-perceived knowledge about TMD in pediatric populations, a high rate of referral of patients with TMD, and a particular interest for professional development opportunities focused on management of TMD.
