Occlusal splint vs Physical therapy (ultrasound, exercise, sensorimotor training, laser, TENS, manual therapy)

Depression · People with temporomandibular disorders (TMD)

CC+CT genotypes vs TT genotype

Dental caries · Children (<18 years) with vs without dental caries

CC+CT genotype at FokI(rs10735810) was associated with ~1.87-fold higher caries risk than TT (dominant model, OR 1.87); ungraded.

Orthodontic removable traction appliance (ORTA) vs no intervention

Overjet · Children and adolescents (aged 16 years or younger) with prominent lower front teeth (Class III malocclusion)

Used a pea-sized amount of fluoride toothpaste or less vs Used more than a pea-sized amount

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years

It is very uncertain whether used a pea-sized amount of fluoride toothpaste or less changes fluorosis (percentage prevalence in permanent teeth) compared with used more than a pea-sized amount (very low certainty).

Second molar distally inclined at extraction vs Second molar upright at extraction

Spontaneous space closure · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)

In the mandible, distal inclination of the second molar vs upright was not significantly associated with space closure (OR 1.18; not GRADE-rated).

Wits appraisal · Children and adolescents (aged 16 years or younger) with prominent lower front teeth (Class III malocclusion)

Non-surgical orthodontic treatment (any: facemask, chin cup, tandem… led to higher wits appraisal compared with no treatment; GRADE not reported.

Intralesional steroid injections vs Alternative medicinal treatments

Maximal mouth opening (interincisal distance) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

Maximal mouth opening (interincisal distance) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

It is very uncertain whether surgery plus Heister jaw opener changes maximal mouth opening (interincisal distance) compared with surgery plus wooden tongue depressors (very low certainty).
