Brief Summary

Myofascial pain is one of the common symptoms in patients with temporomandibular joint disorders. Occlusal splint use, trigger point injections and the combination of this two methods are primary treatment options. Patients were divided into 3 groups and this three treatment was applied. We aimed to investigate the clinical and ultrasonographic effects of the treatments. Patients in the treatment groups were reexamined at 1st and 3rd months, and their clinic and ultrasonographic records were repeated. 16 healthy volunteers were also included in the study. No treatment was applied, only clinical and ultrasonographic records were taken once.

Outcome Measures

Primary Outcomes (4)

  • The change of the elasticity of masseter muscle

    masseter muscle elasticity was evaluated by shear-wave sonoelastography

    Before the treatment (day 0), in the 1st and 3rd months of the treatment

  • The change of the pain score

    Severity of the pain evaluated by the visual analog scale (VAS), rated from 0 (no pain) to 10 (the worst pain)

    Before the treatment (day 0), in the 1st and 3rd months of the treatment

  • The change of the maximum mouth opening

    maximum mouth opening was measured by the reference of right upper and lower central incisors.

    Before the treatment (day 0), in the 1st and 3rd months of the treatment

  • The change of the volume of masseter muscle

    masseter muscle volume was measured by ultrasonography

    Before the treatment (day 0), in the 1st and 3rd months of the treatment

Study Arms (4)

Occlusal Splint Group

ACTIVE COMPARATOR

Only occlusal splint was made for this patients.

Device: Occlusal splint treatment

Masticatory muscle injection group

ACTIVE COMPARATOR

Only intramuscular injection was applied to this patients. Intramuscular injectable form of Lidocaine Hydrochloride (20mg/ml, Jetokain Simplex, ADEKA, Samsun, Turkey) was injected. 0,3 ml was injected to all trigger points.

Procedure: Masticatory muscle injection

Occlusal splint and masticatory muscle injection combination group

ACTIVE COMPARATOR

Intramuscular injectable form of Lidocaine Hydrochloride (20mg/ml, Jetokain Simplex, ADEKA, Samsun, Turkey) was injected. 0,3 ml was injected to all trigger points. Patients were started to use their occlusal splints in the evening of the injection day.

Combination Product: Combination of occlusal splint and masticatory muscle injection treatments

Control group

NO INTERVENTION

16 healthy volunteers was involved. Not given any treatment to these volunteers.

Interventions

Occlusal splint was made for 16 patients and they used just this occlusal splint for 3 months.

Occlusal Splint Group

Lidocaine was injected on 16 patients' three trigger point in the masseter muscle. Injection was repeated 3 times, once a week.

Masticatory muscle injection group

Lidocaine was injected on 16 patients' three trigger point in the masseter muscle. Occlusal splint was also made and they started to use the day which first injection was made. And continue to use the occlusal splint for 3 months. Injection was repeated 3 times, once a week.
