Temporomandibular
Disorders &
Orofacial Pain

Overview: Describe the functional anatomy and physiology of the masticatory system, temporomandibular joint (TMJ), and craniofacial and cervical structures. Explain peripheral and central pain mechanisms, sensitization, and referred pain; review epidemiology and major classification frameworks; and distinguish supported pain mechanisms from unsubstantiated structural explanations.

Core topics

• Pain neurobiology, referred pain, peripheral and central mechanisms, and sensitization.
• Gross and functional anatomy relevant to temporomandibular disorders (TMD).
• Epidemiology and terminology; introduction to the Diagnostic Criteria for TMD (DC/TMD) and the International Classification of Orofacial Pain (ICOP).
• Odontogenic and nonodontogenic pain; clinical interpretation of occlusal and skeletal variation.

Overview: Conduct a comprehensive pain interview integrating medical, dental, sleep, behavioral, and psychosocial information. Perform a standardized examination, identify red flags, develop a prioritized problem list and differential diagnosis, and document findings clearly to support clinical decisions and continuity of care.

Core topics

• Pain history, functional impact, and patient goals.
• Musculoskeletal, TMJ, cervical, cranial nerve, oral, head and neck, and vital sign screening.
• Range of motion, palpation, symptom provocation, and interpretation of examination findings.
• Red flags, urgent referral, diagnostic uncertainty, and Subjective, Objective, Assessment, and Plan (SOAP) documentation.

Overview: Differentiate primary headache disorders, warning features of secondary headache, cranial neuralgias, painful trigeminal neuropathies, persistent idiopathic facial pain, and conditions that mimic odontogenic pain. Recognize medication-overuse headache and coordinate urgent or routine referral according to the clinical presentation.

Core topics

• Primary and secondary headache disorders, mechanisms, and warning features.
• Trigeminal neuralgia and painful post-traumatic trigeminal neuropathy.
• Persistent idiopathic facial pain and other nonodontogenic pain presentations.
• Medication-overuse headache and indications for urgent or routine referral.

Overview: Interpret pain-related disability and psychosocial risk using validated screening tools within the dental scope of practice. Communicate without stigma, incorporate self-management and behavior-change principles, recognize sleep dysfunction, and screen for sleep-related breathing disorders when referral is appropriate.

Core topics

• Biopsychosocial formulation, pain-related disability, pain behavior, and contextual factors.
• Depression, anxiety, somatic symptom burden, and pathways for safety escalation and referral.
• Education informed by cognitive behavioral therapy (CBT), habit reversal, relaxation, stress management, and sleep strategies.
• Use and interpretation of validated screening tools; sleep-related concerns and referral coordination.

Overview: Select imaging and other tests when the results are expected to influence care. Interpret common TMJ imaging findings within their limitations, recognize indications for laboratory studies, psychometric assessment, sleep testing, or specialist consultation, and communicate a focused clinical question to the receiving clinician.

Core topics

• Panoramic imaging, cone beam computed tomography (CBCT), computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound: indications and limitations.
• Incidental findings and correlation of imaging with clinical findings.
• Laboratory studies, systemic disease evaluation, and indications for psychometric assessment and sleep testing.
• Consultation with radiology, neurology, rheumatology, sleep medicine, otolaryngology, behavioral health, and surgery.

Physical Therapy and Cervical Evaluation

Overview: Develop treatment goals linked to the diagnosis and obtain informed consent. Integrate education, self-management, physical therapy, cervical assessment, intraoral appliances, and behavioral strategies. Use shared decision-making, monitor outcomes, coordinate rehabilitation, and revise or discontinue ineffective interventions.

Core topics

• Patient education, reassurance, activity pacing, and self-management.
• Physical therapy, cervical evaluation, home exercise, and rehabilitation referral.
• Selection and monitoring of intraoral appliances and behavioral strategies; sequencing of multimodal care and measurement of outcomes.

Overview: Differentiate the goals and indications of oral appliances used for TMD from those used for obstructive sleep apnea (OSA). Select patients and appliance designs, establish baseline dental and TMJ findings, and plan delivery, adjustment, monitoring, and interdisciplinary follow-up.

Suggested core topics

• TMD appliances: indications, stabilization and other designs, evidence, and limitations.
• OSA appliances: mandibular advancement devices, patient selection, and coordination with the diagnosing sleep clinician.
• Appliance selection, fitting, adjustment, and mandibular advancement titration; comfort and adherence.

Overview: Explore the relationships among sleep, bruxism, TMD, and orofacial pain. Review sleep physiology, differentiate sleep and awake bruxism, recognize sleep-related breathing disorders and other relevant sleep problems, and apply assessment, patient education, and referral strategies within an interdisciplinary model of care.

Suggested core topics

• Bidirectional relationship between sleep disruption and pain.
• Sleep and awake bruxism: definitions, mechanisms, contributing factors, and potential clinical consequences.
• Bruxism assessment using patient reports, clinical findings, and device-based measures when indicated; limitations of tooth wear as a stand-alone marker.
• Snoring, OSA, insomnia, and excessive daytime sleepiness: screening and referral pathways.
• Relationships among bruxism, TMD, headache, and sleep-disordered breathing; interpreting associations without assuming causation.
• Individualized management of bruxism-related consequences, patient education, and follow-up in collaboration with sleep medicine and behavioral health.
