This Cochrane review of the effects of psychological therapies in people (aged 12 years and over) with painful temporomandibular disorders (TMD)lasting 3 months or longer included 22 RCTs. Cognitive behaviour therapy (CBT) was the most frequently studied but overall there was insufficient evidence on which to base a reliable judgement about the efficacy of psychological therapies for painful TMD
This review of the prevalence of tooth grinding and/or clenching in children and adolescents with neurodevelopmental disorders and other developmental anomalies included 77 studies from 2 countries. However a large proportion of the studies were at high risk of bias so the findings need to be interpreted with caution.
This review of cranio-mandibular manual therapy (CMMT) on pain and maximum mouth opening in people with temporomandibular disorders included 6 RCTs. While the available evidence supports the use of CMMT it is of very low quality so should be interpreted cautiously.
This review of the the prevalence of temporomandibular disorders (TMD) in musicians included 13 cross-sectional studies. The finding estimate a pooled prevalence = 53.9% (95%CI; 36.6% to 70.7%) however the certainty of the evidence is graded as very low.
This review the efficacy of stabilisation appliances in the management of painful temporomandibular disorders (TMDs) included 24 RCTs. The findings suggest they have an efficacy beyond the placebo effect however the evidence of low to very low certainty.
This review was to evaluate the prevalence of temporomandibular joint disorders (TMD) among the general population. 21 studies involving a total of 11,535 patients were included with the findings suggesting a prevalence of 29.3% (95%CI; 6.1–72.3%) in adults assessed using the RDC/TMD Criteria.
The review of the use of botulinum toxin type A injections in the management of primary bruxism in adults included 10 studies. Only 6 of the included studies were RCTs and the studies were generally small are very hetrogeneous so additional well designed and conducted RCTs are needed.
This network meta-analysis assessing the effectiveness of various types of occlusal splint in the management of temporomandibular disorders (TMDs) included 48 RCTs suggesting that a hard stabilisation splint achieves superior results in patients with myogenous TMDs. However, many of the included studies are small so teh quality of the evidence is low.
54 patients with temporomandibular joint (TMJ) arthralgia were randomised to recieve either methylprednisolone or saline to reduce pain. Findings suggest no difference in TMJ pain
This review the prevalence of degenerative joint disease (DJD) of the temporomandibular joints included 32 studies only 6 being considered at low risk of bias. While a high prevalence of DJD was seen in patients with juvenile idiopathic arthritis and rheumatoid arthritis the findings should be viewed cautiously.
