Objective: To compare differences in facial growth in patients with isolated clefts of the hard and/or soft palate treated with the minimal incision technique without (MI) or with muscle reconstruction (MMI). Subjects and method: A consecutive series of 170 Caucasian children born with isolated cleft palate were studied. Individuals with other craniofacial malformations, apart from Pierre Robin sequence (PRS), were excluded. The patients were treated surgically with MI (n = 85) or MMI (n = 85) palatoplasty (mean age: 13 months) and divided further into two subgroups: clefts within the soft palate only (small cleft, n = 51) and within the hard and soft palate (big cleft, n = 119)...

The innovative study presented by Huang and co-workers in this issue of the European Journal of Orthodontics is one of the first giving insight into the mostly disregarded world of non-coding ribonucleic acids in orthodontics. In other fields of science non-coding ribonucleic acids have been shown to play a major role in the regulation of cell metabolism as well as the aetiology of diseases such as cancer, Alzheimer's disease, and periodontitis. Their pilot study on the possible function of differentially expressed long non-coding ribonucleic acids during mechanical compression of periodontal ligament stem cells, as well as methodological approach of whole-transcriptome sequencing with bioinformatory analyses, provides ample possibilities for future basic orthodontic research, which will hopefully greatly expand our knowledge of tooth movement regulation...

Background: Closed and open surgical techniques are two different main approaches to surgical exposure of palatally displaced canines (PDCs). Because there is insufficient evidence to support one technique over the other, there is a need for randomized controlled trials. Objectives: To compare surgery time, complications and patients' perceptions between closed and open surgical techniques in PDCs. Trial design: The trial was a multicentre, randomized, controlled trial with two parallel groups randomly allocated in a 1:1 ratio...
