Extraction of the primary (baby) canine (single primary tooth extraction) vs No extraction (non-intervention control)

Number of participants referred for surgical exposure of the PDC · Young people aged 9 to 14 years diagnosed with one or both palatally displaced permanent maxillary canines (PDC)

It is very uncertain whether extraction of the primary (baby) canine (single primary tooth… changes number of participants referred for surgical exposure of the PDC compared with no extraction (non-intervention control) (very low certainty).

Cervical pull headgear vs Minor interceptive procedures (control)

Lower incisors to mandible (relationship of lower front teeth to the mandible) · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth

Cervical pull headgear showed no clear difference in lower incisors to mandible at 2 years compared with minor interceptive procedures (control); GRADE not reported.

Tooth bleaching (combined in-office and home bleaching) vs No bleaching (untreated control)

Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Patients with post-orthodontic white spot lesions and permanent dentition

In the single RCT, all bleached patients were satisfied with the aesthetic outcome, though the trial was at high risk of bias (ungraded).

Bleaching vs No bleaching or alternative control

Colour disparity between carious and non-affected enamel · Permanent teeth with post-orthodontic or artificial white spot lesions

Bleaching may diminish colour disparities between carious and non-affected areas (very low certainty).

Thymosin alpha 1 (10-minute soak prior to replantation) vs Normal saline

Tooth survival · People with avulsed and replanted permanent (front) teeth

It is very uncertain whether thymosin alpha 1 (10-minute soak prior to replantation) changes tooth survival at 12 months compared with control (saline) (very low certainty).

Ledermix root canal medicament (day 0 to 10) vs Ultracal root canal medicament (day 7 to 10)

Aesthetics (discolouration) at 12 months (patient level) · People with avulsed and replanted permanent (front) teeth

It is very uncertain whether ledermix root canal medicament (day 0 to 10) changes aesthetics (discolouration) at 12 months (patient level) compared with ultracal root canal medicament (day 7 to 10) (very low certainty).

Hyperbaric oxygen (following replantation) vs control

Pulpal healing at 12 months · People with avulsed and replanted permanent (front) teeth

It is very uncertain whether hyperbaric oxygen (following replantation) changes pulpal healing at 12 months compared with control (very low certainty).

Professionally-applied 12,300 ppm F APF foam, every 2 months vs 0 ppm F placebo foam

Number of participants with more severe DLs (severity of DLs) · Orthodontic patients of any age with fixed braces (new DLs assessed at debond)

The review found no eligible studies for this question.

Professionally-applied 12,300 ppm F APF foam, every 2 months vs 0 ppm F placebo foam

Number of participants with new demineralised lesions (DLs) · Orthodontic patients of any age with fixed braces (new DLs assessed at debond)

Professionally-applied 12,300 ppm F APF foam, every 2 months may leads to lower number of participants with new demineralised lesions (DLs) compared with 0 ppm F placebo foam (low certainty).

Orthodontic treatment without extraction of permanent teeth vs Orthodontic treatment involving extraction of permanent teeth

Dento-occlusal results of treatment, measured with the PAR index · Children (80% aged <= 16 years) with a Class II division 2 malocclusion (deep bite and retroclined upper front teeth)

The review found no eligible studies for this question.

Fixed functional appliance (FORSUS FRD) vs Fixed functional appliance with mini-implants (FMI)

Final overjet · Adolescents (age 12 to 16 years) receiving orthodontic treatment to correct prominent upper front teeth (Class II malocclusion)

Fixed functional appliance (FORSUS FRD) showed no clear difference in final overjet compared with fixed functional appliance with mini-implants (FMI); GRADE not reported.
