This review aiming to provide information about the association between a superior labial frenum and maxillary midline diastema included 11 cross-sectional studies. The findings suggest that papillary and papillary penetrating frenum may be associated with maxillary midline diastema but the evidence is limited.

This overview of systematic reviews of evidence for the prevention of enamel demineralization during fixed appliance orthodontic treatment included 29 reviews. Most of the reviews were considered to have methodological issues with the findings suggesting that professional fluorides, sealants, reminders, and lasers might be useful interventions to prevent enamel demineralization.

This Cochrane review update of interceptive procedures included 4 RCTs to promote the eruption of palatally displaced permanent canines (PDCs) involving a total of 199 patients. The findings indicate that extraction of the primary canine man increase the the proportion of erupted PDCs but the evidence is very uncertain.

This Cochrane review update of the effects of different orthodontic treatments for posterior crossbites included 31 RCTS eight of whihc were at low risk of bias. They found that for children iaged 7 to 11 years old), quad-helix and expansion plates were more beneficial than no treatment for correcting posterior crossbites.

This review of the the treatment duration required to achieve whole-arch alignment of the mandibular dentition using fixed appliances included 35 RCTs. The pooled duration for whole-arch alignment in the mandible was 263.0 days/8.8 months (95%CI: 6.2 to11.3 months). Mandibular incisor alignment was achieved in 100.7 days/3.4 months (95%CI: 2.8 to 3.9 months).
