OBJECTIVES To analyze the spatiotemporal expression pattern of mmu-miR-181a-5p during palatogenesis and identify possible mRNA targets and their involved molecular pathways. MATERIAL AND METHODS The expression of mmu-miR-181a-5p was analyzed

Self-correction of posterior crossbite in childhood: a systematic review of long-term follow-up studies. Eur. J. Orthod. (IF 2.6) Pub Date : 2023-11-30 Bianka Costa do Nascimento,Cibelle Cristina Oliveira Dos Santos,Milena Cristina Costa Dos Santos,David Normando
BACKGROUND The concept that posterior crossbite is not self-correcting has been controversial in the literature. OBJECTIVE To evaluate the incidence of self-correction of crossbite in different stages of dentition in childhood. SEARCH METHODS AND SELECTION CRITERIA A bibliographic search using the acronym PECOS was performed in five databases and in partial grey literature. Studies evaluating children

Mandibular second premolar distoangulation: a longitudinal follow-up from the mixed to the permanent dentition Eur. J. Orthod. (IF 2.6) Pub Date : 2023-07-15 Beatriz Quevedo, Felicia Miranda, José Roberto Pereira Lauris, Flavio Mauro Ferrari Junior, Daniela Garib
Objective The aim of this study was to assess the frequency of mandibular second premolar (MnP2) distoangulation among orthodontic patients and the angular changes after a longitudinal follow-up. Methods The sample was collected from the orthodontic records of 865 patients. The distoangulation group was composed of 42 patients (mean age 9.29 ± 1.24 years, 16 male, 26 female) with distoangulation of

Do pooled estimates from orthodontic meta-analyses change depending on the meta-analysis approach? A meta-epidemiological study Eur. J. Orthod. (IF 2.6) Pub Date : 2023-07-12 Zacharias Tatas, Ourania Koutsiouroumpa, Jadbinder Seehra, Dimitrios Mavridis, Nikolaos Pandis
Background In meta-analyses involving a few trials, appropriate measures should be employed to assess between-study heterogeneity. When the number of studies is less than five and heterogeneity is evident, the Hartung and Knapp (HK) correction should be used. The aim of this study was to compare the reported estimates of published orthodontic meta-analyses with the pooled effect size estimates and

Risk factors for gingival recessions after orthodontic treatment: a systematic review Eur. J. Orthod. (IF 2.6) Pub Date : 2023-07-11 Maria Cadenas de Llano-Pérula, Ana Belén Castro, Margaux Danneels, Alix Schelfhout, Wim Teughels, Guy Willems
Summary Background/objectives To systematically review the available evidence concerning the risk factors for gingival recessions (GR) after orthodontic treatment (OT). Data collection and analysis Data was obtained and collected by systematically searching 3 data bases: Pubmed, EMBASE, and Web of Science until 20 April 2023. Controlled trials, cohort, case-control or cross-sectional studies describing

Reliability and time-based efficiency of artificial intelligence-based automatic digital model analysis system Eur. J. Orthod. (IF 2.6) Pub Date : 2023-07-07 Jae-Hun Yu, Ji-Hoi Kim, Jing Liu, Utkarsh Mangal, Hee-Kap Ahn, Jung-Yul Cha
Summary Objectives To compare the reliability, reproducibility, and time-based efficiency of automatic digital (AD) and manual digital (MD) model analyses using intraoral scan models. Material and methods Two examiners analysed 26 intraoral scanner records using MD and AD methods for orthodontic modelling. Tooth size reproducibility was confirmed using a Bland–Altman plot. The Wilcoxon signed-rank

Under pressure-mechanisms and risk factors for orthodontically induced inflammatory root resorption: a systematic review. Eur. J. Orthod. (IF 2.6) Pub Date : 2023-09-18 Hassan M Dawood,Annika Kroeger,Vinay Chavda,Iain L C Chapple,Moritz Kebschull
BACKGROUND The application of orthodontic forces causes root resorption of variable severity with potentially severe clinical ramifications. OBJECTIVE To systematically review reports on the pathophysiological mechanisms of orthodontically induced inflammatory root resorption (OIIRR) and the associated risk factors based on in vitro, experimental, and in vivo studies. SEARCH METHODS We undertook an

Core outcomes for orofacial clefts: reconciling traditional and ICHOM minimum datasets Eur. J. Orthod. (IF 2.6) Pub Date : 2023-06-09 Peter A Mossey, Jason Lai, Maria Costanza Meazzini, Corstiaan Breugem, Hans Mark, Aebele B Mink van der Molen, Martin Persson, Gareth Davies, Terumi Okada Ozawa
Summary Objective/Design/Setting This retrospective study sought voluntary participation from leading cleft centres from Europe and Brazil regarding core outcome measures. The results of this study would inform the debate on core outcome consensus pertaining to the European Reference Network for rare diseases (ERN CRANIO) and achieve a core outcome set for cleft care providers worldwide.

Early prevention of maxillary canine impaction: a randomized clinical trial Eur. J. Orthod. (IF 2.6) Pub Date : 2023-06-02 Guy Willems, Charlotte Butaye, Margot Raes, Chen Zong, Giacomo Begnoni, Maria Cadenas de Llano-Pérula
Summary Objectives To investigate the effect of three interceptive measures (slow maxillary expansion (SME) with removable plates (1), extraction of both upper deciduous canines (DC) (2) and no intervention (3)) on maxillary canine (MC) position in patients with early mixed dentition (EMD) and lack of upper arch space. These three groups were additionally compared to a control group (4) with adequate

Biological characteristics of microRNAs secreted by exosomes of periodontal ligament stem cells due to mechanical force. Eur. J. Orthod. (IF 2.6) Pub Date : 2023-07-31 Xiaowen Zheng,Ning Zhao,Liying Peng,Zhenxia Li,Chao Liu,Qingling You,Bing Fang
BACKGROUND Orthodontic tooth movement (OTM) has previously been considered an inflammatory process. However, recent studies suggest that exosomes may play an important role in the cellular microenvironment of OTM. microRNAs (miRNAs) are one of the major constituents of exosomes. This study aims to investigate the biological characteristics of miRNAs secreted by exosomes of periodontal ligament stem
