[Quality evaluation of randomized controlled trials on treatment of cognitive-behavioral therapy on temporomandibular disorders].

OBJECTIVE

To evaluate methodological and reporting quality of the randomized controlled trials on cognitive-behavioral therapy(CBT) on temporomandibular disorders(TMD).

METHODS

The electronic databases of Medline via Ovid, EMBASE, Cochrane Central Register of Controlled Trial, CBM and CNKI, and five Chinese stomatological journals were included to collect randomized controlled trial(RCT) and quasi-RCT(qRCT) on CBT on TMD. Data were assessed using the quality assessment criteria recommended by the Cochrane Collaboration, and the reporting quality was assessed using the consolidated standards of reporting trials (CONSORT) checklist.

RESULTS

232 articles were collected by the search strategy, of which 5 (3 RCTs and 2 qRCTs) met the inclusion criteria. The methodological quality varied among the studies with 2 scored as B and 3 as C. The highest score evaluated by the CONSORT checklist was 24.

CONCLUSION

The methodological qualities of included studies on CBT on TMD are generally low, and its reporting quality which is checked by CONSORT is also unsatisfactory yet.
