The fascinating world of non-coding RNA and how it may help to unravel the mysteries of tooth movement regulation.

Eur J Orthod 2018 Oct 13. Epub 2018 Oct 13.

Department of Orthodontics, University Medical Centre of Regensburg, Regensburg, Germany.

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.

Treatment of missing maxillary lateral incisors: a clinical and aesthetic evaluation.

Eur J Orthod 2018 Sep 11. Epub 2018 Sep 11.

Department of Orthodontics, The Institute for Postgraduate Dental Education, Jönköping, Sweden.

Objective: The aim of this study was to evaluate whether implant therapy or orthodontic space closure was the best treatment option for patients with missing maxillary lateral incisors.

Subjects And Methods: The implant group (I group) consisted of 22 patients aged <26 years who had one or both maxillary lateral incisors substituted by a single implant-supported crown. The space-closure group (SC group) consisted of patients matched with I group patients based on diagnosis, gender, and number. Read More

A geometric morphometric evaluation of hard and soft tissue profile changes in borderline extraction versus non-extraction patients.

Eur J Orthod 2018 Sep 13. Epub 2018 Sep 13.

Department of Orthodontics, School of Dentistry, National and Kapodistrian University of Athens, Athens, Greece.

Objectives: To evaluate the hard tissue and facial profile changes in matched extraction and non-extraction Class I patients by the use of geometric morphometrics.

Subjects And Methods: From a parent sample of 542 Class I patients, previously subjected to discriminant analysis, a subsample of 68 borderline cases was obtained, 34 treated with extraction and 34 without extraction of 4 first premolars. Geometric morphometric methods (Procrustes superimposition and Principal Component Analysis) were applied on cephalometric tracings to assess the validity of the discriminant analysis in successfully identifying a morphologically homogeneous group and to evaluate inter- and intra-group skeletal and facial profile shape changes.

Reliability of upper airway assessment using CBCT.

Eur J Orthod 2019 01;41(1):101-108

Division of Orthodontics, Faculty of Dentistry, University of British Columbia, Vancouver, British Columbia, Canada.

Background: Upper airway analysis is an often-cited use of CBCT imaging by orthodontists; however, the reliability of airway measurements using this technology is not fully established.

Objective: To determine the intra-examiner and inter-examiner reliability of the complete process of volumetric and cross-sectional area assessments of the upper airway using CBCT imaging.

Materials And Methods: Six examiners of varying levels of education and clinical experience performed the steps necessary for airway analysis, including manual orientation, slice and threshold selection and measured nasopharyngeal, oropharyngeal, hypopharyngeal and total upper pharyngeal airway volumes in addition to minimum cross-sectional area on the CBCT images of 10 patients.

Bracket slot size selection: after all a matter of taste?

Authors:
Theodore Eliades

Eur J Orthod 2018 Aug 31. Epub 2018 Aug 31.

Clinic of Orthodontics and Pediatric Dentistry, Center of Dental Medicine, University of Zurich.

The publication of the three-paper series on the effects of two slot sizes on treatment parameters in this issue, targets a topic, which has attracted a lot of discussion based primarily on anecdotal evidence. The conclusive evidence contribute to the lack of variation of treatment variables with slot size selection, clarifies one of the traditional beliefs on this issue; several others still hold strong however. This commentary has the objective of highlighting some points, which could be taken into consideration in interpreting the results of this three-part trial. Read More

Department of Orthodontics, Peking University School and Hospital of Stomatology, Beijing.

Objective: The role of long non-coding ribonucleic acids (lncRNAs) during orthodontic tooth movement remains unclear. We explored the lncRNA landscape of periodontal ligament stem cells (PDLSCs) subjected to compressive force.

Materials And Methods: PDLSCs were subjected to static compressive stress (2 g/cm2) for 12 hours. Read More
