Randomized Controlled Trial Comparative Study Clinical Trial
Treatment effect on signs and symptoms of temporomandibular disorders--comparison between stabilisation splint and a new type of splint (NTI). A pilot study.
The aim of the investigation was to compare the effect on signs and symptoms of temporomandibular disorders (TMD) of two different interocclusal appliances. Thirty patients with signs and symptoms of TMD received either a stabilisation splint or a new kind of splint based on the concept of nociceptive trigeminal inhibition (NTI). A clinical examination was performed and subjective symptoms were registered before start of treatment and after 3 and 6 months. ⋯ All 14 who had been treated with a stabilisation splint reported some (n = 2) or significant (n = 12) improvement. For all variables registered, the results were in favour for the stabilisation splint. One subject treated with a NTI splint exhibited an impaired occlusion at the 6-month follow-up.

Comparative Study
Symptoms and signs of temporomandibular disorders in individuals with chronic whiplash-associated disorders.
The purpose of this study was to compare the prevalence of temporomandibular disorders (TMD) between individuals with chronic whiplash-associated disorders (WAD) and a group of age- and sex-stratified patients attending a Public Dental Service (PDS) clinic. Fifty-four individuals diagnosed with chronic WAD that were referred to a rehabilitation centre constituted the WAD group. The control group consisted of 66 patients at a PDS clinic (C group). ⋯ Pain on mandibular mobility was reported by 30% in the WAD group and by 3% in the C group (p < 0.001). In conclusion, the prevalence of TMD was higher among individuals with chronic WAD compared with an age- and sex-stratified cohort of patients in a general dental practice. The results indicate that trauma to the neck also affects temporomandibular function.
