Mandibular propulsion appliance for adults with Class II malocclusion: a systematic review and meta-analysis.

Background: The effects of mandibular propulsion appliances in adults have some controversial results. While some authors claim that its use in non-growing patients could produce some dentoskeletal effects, other studies indicate that Class II correction occurs only through significant dental effects.

Objective: To evaluate the effects in non-growing Class II patients with mandibular retrusion, promoted by the treatment with mandibular propulsion appliances and determine if they produce mandibular changes.

Lower fixed retainers: bonded on all teeth or only on canines? .

Objective: To evaluate the stability after orthodontic treatment between two types of lower fixed retainers: those bonded onto all anterior teeth or those bonded only onto the canines.

Materials And Methods: The following electronic databases were consulted: PubMed, Scopus, Web of Science, Cochrane Library, Lilacs, OpenGrey, ClinicalTrials, and Google Scholar. No restriction of language or year were applied.

miRNAs as biomarkers of orofacial clefts: A systematic review.

Orofacial clefts are facial malformations caused by the improper development of the lips and palate. Many genetic and epigenetic molecules have been involved in the mechanisms of orofacial clefts, one of which are miRNAs. This systematic review aimed to identify miRNAs associated to non-syndromic orofacial clefts in humans.
