Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

ElementPlanned (methods)Found (results)
PopulationAdults aged 18 years or older with clinically diagnosed TMD (exhibiting two or more of the listed signs and/or symptoms); no age restriction for prevention trials provided follow-up extended into adulthood; TMD required clinically absent at baseline for prevention studies; any signs/symptoms associated with pain of dental origin excludedNo studies met the inclusion criteria; four retrieved full texts were all excluded (n=0)
InterventionOrthodontic treatment with appliances that could induce stable, permanent orthodontic tooth movement; patients receiving splints for 8 to 12 weeks excluded; studies using splints prior to orthodontic appliances excluded; surgical interventions excludedNo studies met the inclusion criteria (n=0)
ComparisonControl groups receiving no treatment, placebo, or reassuranceNo studies met the inclusion criteria (n=0)
OutcomesPrimary: overall symptoms, pain and headache (relief from symptoms by global measures; frequency/severity/duration). Secondary: limitation of movement. Also adverse effects on oral health and quality of life. Outcome measurement at least 6 months after interventionNo studies met the inclusion criteria; no outcomes could be assessed (n=0)
Study designsAll randomised controlled trials (RCTs), including quasi-randomised trialsNo studies met the inclusion criteria (n=0)
TimingAt least 6 months after the intervention (prevention trials followed into adulthood)No studies met the inclusion criteria (n=0)
