Fixed tooth-borne expansion (quad-helix) vs Removable tooth-borne expansion (expansion plate)

Molar expansion · Children and adults with a posterior crossbite, without a Class III skeletal relationship, cleft lip or palate (or both), or other…

Fixed tooth-borne expansion (quad-helix) leads to higher molar expansion (inter-molar distance) compared with removable tooth-borne expansion (expansion plate) (high certainty).

Self-ligating brackets vs Conventional brackets

Time to alignment · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth

Self-ligating brackets showed no clear difference in time to alignment (days) compared with conventional brackets; GRADE not reported.

Lower lingual arch vs No active treatment (control)

Size of the lower jaw (arch length) · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth

Lower lingual arch led to higher size of the lower jaw (mandibular arch length) at 1 year compared with no active treatment (control); GRADE not reported.

ARP with allograft plus synthetic cell-binding peptide P-15 vs ARP with allograft without P-15

Changes in bucco-lingual/palatal width of alveolar ridge (mm) · Adults aged 18 years or older, in good general health (including well-controlled systemic disease), requiring extraction of one or more…

It is very uncertain whether ARP with allograft plus synthetic cell-binding peptide P-15 changes changes in bucco-lingual/palatal width of alveolar ridge (mm) compared with ARP with allograft without P-15 (very low certainty).

Extraction of lower deciduous canines vs No active treatment (control)

Lower incisor inclination (lingual tipping and retrusion) · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth

Extraction of lower deciduous canines showed no clear difference in lower incisors to mandible (inclination, degrees) at 1 year compared with no active treatment (control); GRADE not reported.

ARP with alloplast vs ARP with xenograft

Need for additional augmentation prior to implant placement · Adults aged 18 years or older, in good general health (including well-controlled systemic disease), requiring extraction of one or more…

It is very uncertain whether ARP with alloplast changes need for additional augmentation prior to implant placement compared with ARP with xenograft (very low certainty).

Dental caries prevalence · General population in Ethiopia (all ages, age range 6-100 years)

The pooled prevalence of dental caries in Ethiopia (2000-2020) was 40.98% (95% CI 31.62 to 50.34), with very high heterogeneity (I2=98.6%); certainty not graded.

Schwarz appliance vs No active treatment (control)

Position of the incisors (upper incisor inclination) · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth

Schwarz appliance showed no clear difference in upper incisors to maxilla (inclination, degrees) at 9 months compared with no active treatment (control); GRADE not reported.
