PURPOSE: To determine the association of atypical swallowing (AS) with relapse in patients undergoing combined orthodontic and orthognathic treatment. MATERIALS AND METHODS: In this retrospective cohort study, the clinical data of all patients who underwent combined surgical and orthodontic treatment from 1998 through 2015 at the University Hospital of Geneva (Geneva, Switzerland) were reviewed. The primary outcome variables were 1) AS and 2) post-treatment relapse...

BACKGROUND: Aim of this study was to analyze the efficacy and precision of the completely customized lingual appliance (CCLA) regarding the single tooth torque correction. The study also examined external apical root resorptions as possible side effects of torque correction and the changings of the periodontal situation. METHODS: A case series of three patients were included. The patients showed a single tooth torque problem with a gingival recession and were treated with the CCLA...

Objective: We studied longitudinally the associations of craniofacial morphology, mouth breathing, orthodontic treatment, and body fat content with the risk of having and developing sleep disordered breathing (SDB) in childhood. We hypothesized that deviant craniofacial morphology, mouth breathing, and adiposity predict SDB among children. Materials and methods: The participants were 412 children 6-8 years of age examined at baseline and 329 children aged 9-11 years re-examined at an average 2...

Objective: To evaluate the online visibility of the most popular orthodontic articles in Web platforms in relation to publication details and citations. Materials and Methods: Altmetric Explorer (Altmetric LLP, London, UK) was searched for articles published in 11 orthodontic journals without time limits in publication and citation on social media. The 200 articles with the highest Altmetric Attention Score (AAS) were collected and screened for data related to publication (date, journal, access), authorship (number of authors, affiliation and origin of the corresponding author), and research (type, subject, funding)...

Background: The effect of low-level laser therapy (LLLT) on accelerating orthodontic tooth movement has been extensively studied; however, there is limited knowledge on the use of LLLT on orthodontic root resorption. Objective: To investigate the effect of LLLT on orthodontically induced inflammatory root resorption (OIIRR) and to compare the difference between pulsed and continuous LLLT on OIIRR. Trial design: Double-blind, single-centre 3-arm parallel split-mouth randomized controlled trial...

Background: Self-esteem (SE) is suggested to influence the relationship between orthodontic treatment need and oral health-related quality of life (OHRQoL), but evidence lacks. The aim of the present study was to investigate SE in the relationship between subjective orthodontic need and OHRQoL in children. Methods: This cross-sectional study was embedded in the Generation R Study, a multi-ethnic population-based cohort. In total, 3796 10-year old children participated in the present study...

OBJECTIVES: This study aims to describe morphological peculiarities of maxillary and mandibular first molars in Europeans, Asians and Europeans with cleft lip and palate. MATERIAL AND METHODS: Reflex microscopy was used to obtain three-dimensional morphometric landmarks from 40 models (11 Europeans and 13 Asians without cleft lip and palate, 16 Europeans with unilateral cleft lip and palate). The cases were examined using traditional morphometry and geometric morphometry, and visualized using thin-plate splines...

OBJECTIVE: To investigate the effect of flapless osteoperforation on the tissue response of the atrophic alveolar ridge affected by orthodontic tooth movement (OTM). MATERIALS AND METHODS: An atrophic alveolar ridge model was established in the mandibular quadrants of eight beagle dogs. As a split-mouth design, the quadrants were randomly divided into group C (OTM only) and group OP (OTM with flapless osteoperforation). The rate of OTM for 10 weeks was compared between groups, and micro-CT-based histomorphometric analysis and RNA-sequencing-based gene-enrichment analysis were performed targeting the atrophic ridge...

OBJECTIVES: Gingival crevicular fluid (GCF), the inflammatory infiltrate within the crevicular sulcus, is of great importance for diverse processes in the oral cavity and has a high impact in oral sciences. It is assumed to serve as a source of biomarkers for systemic or periodontal diseases and mediators of orthodontic tooth movement. In order to characterize the protein content of the GCF in an unbiased and complete approach, we employed mass spectrometry (MS), which allows not only the identification, but also the quantification of these proteins...

Tooth replacement in the anterior maxilla is most often indicated after traumatic dental injury or due to congenital missing teeth. Treatment alternatives include implant-supported restorations, conventional fixed bridges, acid-etched bridges, orthodontic space closure, or autotransplantation. Dental implants have gained increased popularity over the last 40 years. However, this treatment modality is contraindicated in patients with continuous growth of the alveolar process due to the risk of severe infrapostion of the dental implant...

BACKGROUND: The objectives of this study were to evaluate retention procedures and protocols which are used by the orthodontists in Lithuania and to identify commonly used types of dental retainers. METHODS: One hundred seven questionnaires in total with 28 multiple-choice questions were sent to all members of the Lithuanian Orthodontic Society. The questionnaire was organized into eight sections representing specific information about socio-demographic status of the respondents, selection of a retention system, details of commonly used fixed and removable retainers, the duration of the retention period, supervision of the retainers, instructions for patients, and necessity of common retention guidelines...

Currently, there are three major groups of dentists who provide orthodontic services to the public: postgraduate trained orthodontists, postgraduate trained pediatric dentists, and general dentists who have taken various orthodontic training courses. All of them can expect to encounter a variety of clinical situations that require a proper understanding of how normal temporomandibular joints (TMJs) function, and also how the masticatory system can develop pain-dysfunction problems; those problems are classified and defined as temporomandibular disorders (TMDs)...

PURPOSE: This study determined and compared the distances from the maxillary root apices of posterior teeth to the floor of the maxillary sinus, or maxillary sinus distances (MSDs), and the distances from the mandibular root apices of the posterior teeth to the mandibular canal, or mandibular canal distances (MCDs), in Thai subjects with skeletal open bite and skeletal normal bite. MATERIALS AND METHODS: Pretreatment cone-beam computed tomography (CBCT) images were obtained from 30 Thai orthodontic patients (15 patients with skeletal normal bite and 15 with skeletal open bite) whose ages ranged from 14 to 28 years...

To investigate the effect of growth hormone on osteopontin expression during orthodontic tooth movement in rats.
 Methods: Forty male Wistar rats (2 weeks, average weight 200 g) were randomly divided into a control group and an experimental group (n=20 per group). The experimental group received subcutaneous injections of growth hormone at a dose of 0.15 U/(kg.d), and the control group received equivalent volumes of saline. A nickel-titanium spring was fixed between the maxillary incisors and the left upper first molar with a force of 0...

INTRODUCTION: There exist a number of factors that affect the outcome of orthodontic treatment. These factors can be assessed by various gingival markers. One such maker is myeloperoxidase (MPO). Hence, we planned the present study to assess and compare the MPO activity in the gingival crevicular fluid (GCF) of subjects undergoing orthodontic treatment by different aligning arch wires. MATERIALS AND METHODS: The present study included assessment of patients who underwent orthodontic treatment for crowding of anterior teeth...

BACKGROUND: Orthodontic treatment is one of the commonly used dental treatments. Orthodontic forces act on the bone by modulating the biomolecules, chiefly the osteoprotegerin (OPG), osteopontin (OPN), receptor activator of nuclear factor kappa-B (RANK), and RANK ligand (RANKL) (OPG ligand). Hormonal changes are known to cause marked alteration in the levels of these biomolecules. Hence, we planned this study to evaluate the response of bone biomarkers in the gingival crevicular fluid (GCF) in postmenopausal women undergoing fixed orthodontic therapy...
