BACKGROUND

To evaluate the effectiveness of three minimally invasive techniques for managing patients with myofascial pain dysfunction, determine their association with sociodemographic factors, habits, medication usage, comorbidities, treatment history, pain duration, complaint intensity, and diagnosis limitations.

MATERIAL AND METHODS

This five-year observational study scrutinized 1,000 medical records from individuals treated at the TMD Orofacial Dental Research Center. TMD treatments were organized into Group 1 (thermotherapy, exercises, and CBT), Group 2 (Group 1 plus intramuscular manual therapy), and Group 3 (Group 1 and Group 2 plus occlusal appliances) and correlated with sociodemographic factors, habits, prior medication usage, comorbidities, history of prior treatments, duration of pain, intensity of complaint, and diagnosis limitations or without limitations regarding the symptoms of muscular temporomandibular disorders (TMD).

RESULTS

Treatment durability was proportionally higher in Groups II and III (p<0.05). Although no significant differences were found for habits (p= 0.051) and pain duration (p= 0.001), clenching was more prevalent in Groups II n= 77 (57.0%) and III n= 39 (63.9%) and among those with therapy duration equal to or greater than 6 months for n=102 (59.3%). Statistically significant correlations were noted between age and education (rho=-0.198; p<0.001) and between pain duration and treatment durability (rho=0.317; p<0.001).

CONCLUSIONS

Intraoral devices do not constitute the primary treatment for myofascial pain. For cases of prolonged pain, comorbidities, limited mouth opening, and a history of prior medication or treatments, a splint combined with other therapies is recommended for effective management. Key words:Temporomandibular disorders, myofascial pain, occlusal appliances, clinical diagnosis, thermotherapy, exercise therapy, cognitive behavioral therapy.
