Sixteen studies were included in this review of oral appliances for sleep bruxism. The included studies were small and mainly short term and only 7 studies were RCTs . Although the availabel evidence suggests a short term benefit further high-quality studies of longer duration are needed.
This review of pharmacological management of orofacial pain included 41 studies. Evidence suggests that for TMD joint pain NSAIDs, corticosteroids and hyaluronate injections are beneficial and that clonazepam and capsaicin are effective for burning mouth syndrome.
This review of the association between temporomandibular disorders and dental occlusion included 25 observational studies. No consistent association was found.
Only 5 small low quality studies were included in this review of botulinum toxin (BoNT-A ) injections for sleep bruxism. 3 of the included studies were RCTs and while a potential benefit from use of BoNT-A treatment was suggested the findings should be treated very cautiously.
This review of TMJ lavage for temporomandibular disorders only included 5 small RCTs a majority of which were at high risk of bias. While the findings suggest a benefit from lavage this should be interpreted cautiously because of the limited quality of the available evidence.
This review of otologic signs & symptoms in patients with temporomandibular disorders included just 8 studies and highlights a high frequency but the findings should be interpreted with caution because of the limited quality of available studies.
This review of intra-articular injections of hyaluronic acid (HA) for temporomandibular disorder only identified 8 small studies of limited quality providing no consensus that HA injections were better than other agents.
Eight studies were included in this review of the effect of conservative temporomandibular therapies on otologic symptoms . While most suggested an improvement the quality of the available evidence is limited.
This review included 8 RCTs with some evidence to show that manual therapy improves pain and maximum mouth opening in patients with TMD. However, the limited number of studies and the heterogeneity of the interventions require further studies with standardised evaluations and better study designs.
The review of sleep bruxism was only able to identify 12 small low quality RCTs covering a range of treatments. Most evidence was available for oral appliances but there is no sufficient evidence to state that the occlusal splint is effective for treating sleep bruxism.
