“…Our study showed higher prevalence in all sub‐diagnoses in both groups compared to the NFBC study population, which showed a prevalence of less than 10% in all sub‐diagnoses. The NFBC subjects also showed lower levels of pain‐related TMD symptoms (18%) compared to our study, where 57% of the controls (Group 2) and 50% of the treated patients (Group 1) had TMD‐related pain.…”

Summary Background Severe malocclusions may cause functional and aesthetic problems and symptoms of temporomandibular disorders (TMD). Studies have investigated association between malocclusions and TMDs and shown controversial findings. Objective Purpose of this investigation was to examine the prevalence of TMD sub‐diagnoses, using Diagnostic Criteria for the TMD (DC/TMD), in patients with Class II malocclusion and retrognathic mandible who had undergone mandibular advancement surgery 4‐8 years previously, and to compare their frequencies with non‐treated patients with a similar pre‐existing condition. Methods Study cohort comprised 151 patients who had orthognathic treatment due to mandibular retrognathia in 2007‐2011. Seventy‐seven (51%) participated in the study (Group 1). Group 2 comprised 22 patients who were planned for orthognathic treatment but had not started their treatment. Patients filled in the Finnish version of the DC/TMD Symptom Questionnaire and were examined using to the DC/TMD Axis I. DC/TMD Symptom Questionnaire were inquired by phone from 24 of the 74 patients who did not participate in the study. Results Results showed that Group 2 had more myalgia (13% vs 50%, P < 0.001) and arthralgia (18% vs 65%, P < 0.001) sub‐diagnoses than Group 1. A tendency was noted that Group 2 had more pain‐related TMD symptoms than Group 1. No differences were found between Groups 1 and 3 in gender and age distribution or frequency TMD symptoms. Conclusion Prevalence of especially pain‐related TMD diagnoses was higher in Group 2 compared to Group 1, thus indicating a possible beneficial effect of this treatment for TMD.

Background Exercises are used to treat temporomandibular disorders (TMD), but they are often assessed with other therapies. Local endurance exercises may alter the resistance to fatigue and pain. Objective To assess the effects of an 8‐week protocol of local endurance exercises of masticatory muscles on muscle excitation, force response, perceived pain and over muscle efficiency. Design Randomised controlled trial. Setting Ambulatory care. Subjects In a placebo randomised controlled trial, 46 women with TMD and oro‐facial pain were randomised into intervention group and placebo group. The intervention group received a protocol of biting endurance exercises, controlled by biofeedback. The placebo group received a placebo (simulated laser therapy). Main Outcome Measures The primary outcomes were collected at baseline, 4 weeks and 8 weeks. Pain was assessed through visual analogue scale (VAS) and pressure pain thresholds (PPT). Bite force was collected by a load cell synchronised with surface electromyography of masticatory muscles, bilaterally. Results Pain scores decreased for both groups, but the intervention group showed lower values at 8 weeks. No differences were noted between groups for PPT, but the results increased for both overtime. Time until fatigue and muscle efficiency were higher in the intervention group vs placebo group in both within‐ and between‐subject analysis. Force increased from 4 to 8 weeks in the PG, without differences between groups. Temporal muscle excitation was higher on 8 weeks compared with baseline for the intervention group, without differences between groups. Conclusion Eight‐week exercise protocol of muscle endurance alleviates the pain and improves the resistance to fatigue and muscle efficiency in TMD subjects.
