Open surgical exposure vs Closed surgical exposure

Treatment time: time from surgical exposure to eruption/bonding a bracket · People with maxillary palatally displaced (impacted) canines, unilateral or bilateral (children/adolescents; mean ages 14.2 to 17.5 years)

Open surgical exposure led to lower treatment time: time from surgical exposure to eruption/bonding a… compared with closed surgical exposure; GRADE not reported.

Dementia (any type or severity) vs Older people without dementia

Caries experience (mean DMFT) · Older people (aged 60 years or older) with dementia

The DMFT index was similar between groups, with only 1 of 5 comparative studies finding a significant difference; no meta-analysis was performed (ungraded).

Open surgical exposure vs Closed surgical exposure

Aesthetics: canine rated as abnormal position in the dental arch · People with maxillary palatally displaced (impacted) canines, unilateral or bilateral (children/adolescents; mean ages 14.2 to 17.5 years)

Open surgical exposure showed no clear difference in aesthetics: canine rated as abnormal position in the dental arch compared with closed surgical exposure; GRADE not reported.

Dementia (any type or severity) vs Older people without dementia

Denture use (prevalence) · Older people (aged 60 years or older) with dementia

Denture use was similar in older people with and without dementia, though one study reported lower denture use with more severe dementia; no meta-analysis was performed (ungraded).

NSAID (systemic) vs paracetamol

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · People undergoing orthodontic treatment (any age; 9 to 34 years in included studies)

NSAID (systemic) showed no clear difference in pain intensity (VAS 0-100 mm) compared with paracetamol (low certainty).

Gum health: gingival recession (six-point probing) · People with maxillary palatally displaced (impacted) canines, unilateral or bilateral (children/adolescents; mean ages 14.2 to 17.5 years)

Open surgical exposure showed no clear difference in gum health: gingival recession (six-point probing) compared with closed surgical exposure; GRADE not reported.

Open surgical exposure vs Closed surgical exposure

Patient response: total discomfort score (pain, difficulty eating, brushing, speaking, bad taste) · People with maxillary palatally displaced (impacted) canines, unilateral or bilateral (children/adolescents; mean ages 14.2 to 17.5 years)

Open surgical exposure showed no clear difference in patient response: total discomfort score (pain, difficulty eating,… compared with closed surgical exposure; GRADE not reported.

Topical NSAID (ketoprofen lysinate mouthwash, 160 mg) vs Topical NSAID (benzidamine hydrochloride mouthwash, 22.5 mg)

Topical NSAID (ketoprofen chewing gum) vs Local anaesthetic (benzocaine chewing gum)

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · People undergoing orthodontic treatment (any age; 9 to 34 years in included studies)

It is very uncertain whether topical NSAID (ketoprofen chewing gum) changes pain intensity (VAS 0-100 mm) compared with local anaesthetic (benzocaine chewing gum) (very low certainty).
