Superelastic NiTi arch wire vs Titanium-niobium-tantalum-zirconium (TiNbTaZr) arch wire

Alignment rate · People receiving orthodontic treatment with fixed appliances (upper and/or lower full arch)
1 finding from 1 review

Coated superelastic NiTi wire (BioCosmetic, Titanol, TP Aesthetic or Tooth Tone) vs A different coated superelastic NiTi wire

Alignment rate · People receiving orthodontic treatment with fixed appliances (upper and/or lower full arch)

Fluoride toothpaste 440 ppm (lower concentration) vs 1450 to 1500 ppm F toothpaste

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

Fluoride toothpaste 440 ppm (lower concentration) probably leads to lower fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1450 ppm (higher concentration) (moderate certainty).

Facemask with rapid maxillary expansion (RME) vs Reverse Twin Block with lip pads and rapid maxillary expander (RME)

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

Facemask with rapid maxillary expansion (RME) led to lower wits appraisal compared with reverse Twin Block with lip pads and rapid maxillary expander (RME); GRADE not reported.

Facemask (RME) or modified facemask vs Surgically-anchored appliance (miniscrews or miniplates)

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

Facemask (RME) or modified facemask showed no clear difference in ANB compared with surgically-anchored appliance (miniscrews or miniplates) (low certainty).

SDF (given at a particular frequency, concentration, or duration) vs SDF (given at a different frequency, concentration, or duration)

Secondary prevention of caries · Children and adults (with or without carious lesions)

It is very uncertain whether SDF (given at a particular frequency, concentration, or duration) changes secondary prevention of caries compared with SDF (given at a different frequency, concentration, or duration) (very low certainty).
