INTRODUCTION: Our objective was to develop a photographic setup that would simultaneously capture subjects' smiles from 3 views, both statically and dynamically, and develop a software to crop the produced video clip and slice the frames to study the smile at different stages. METHODS: Facial images were made of 96 subjects, aged 18 to 28 years, in natural head position using a standardized setup of 3 digital single lens reflex cameras, with a reference sticker (10 × 10 mm) on the forehead of each subject...

INTRODUCTION: The objectives of this study were to examine adverse clinical events after the use of the Invisalign system and to provide an overview of the actions taken by the manufacturer to address these events. METHODS: A retrospective analysis of the Manufacturer and User Facility Device Experience database of the United States Food and Drug Administration was used. All medical device reports reported to the United States Food and Drug Administration pertaining to products of Align Technology from November 1, 2006, to November 30, 2016, were analyzed...

Patients with a severe gummy smile and a skeletal Class II profile are difficult to treat. This case report describes an effective treatment alternative for improving a gummy smile in a patient with a severe Class II molar relationship, severe crowding, and lip protrusion using zygomatic anchorage devices and improved superelastic nickel-titanium wires. A 36-year-old woman had an excessive overjet and a deep overbite with a bilateral Angle Class II molar relationship. The cephalometric analysis demonstrated a Class II skeletal relationship (ANB, 9...

This article describes the complex dental treatment of a 43-year-old man with skeletal Class II, mandibular asymmetry, severe brachyfacial pattern, Class II Division 2, canting of the occlusal plane, and an increased curve of Spee. To achieve optimal results, we adopted a multidisciplinary approach to treatment, involving periodontics, oral surgery, orthodontics, maxillofacial surgery, and prosthetics specialists. After periodontal treatment, miniscrews were placed to correct the occlusal plane canting and the excessive curve of Spee with orthodontic treatment...

INTRODUCTION: There has been no epidemiologic study of malocclusion prevalence and treatment need in the United States since the Third National Health and Nutrition Examination Survey, conducted from 1988 to 1991. In this descriptive study, the authors sought to estimate orthodontic treatment prevalence by examining a nationally representative survey to assess current pediatric dental and orthodontic utilization. METHODS: The 2009 and 2013 Medical Expenditure Panel Surveys were used to categorize and compare all types of pediatric dental and orthodontic procedures in children and adolescents up to 20 years old...

INTRODUCTION: Treatment of Class II Division 1 malocclusion with orthopedic devices combined with fixed orthodontic appliances has shown excellent results when used in growing patients. We aimed to evaluate the long-term stability of the cephalometric changes obtained during Class II malocclusion correction with the Jasper jumper associated with fixed appliances. METHODS: The treatment group comprised 24 patients who were evaluated at 3 stages: pretreatment, posttreatment, and long-term posttreatment...

INTRODUCTION: The purpose of this study was to investigate the mechanical loading-induced changes in protein and mRNA expressions of interleukin-6 (IL-6) and its key signaling factors glycoprotein 130 (gp130), signal transducer and activator of transcription 3 (STAT3), and the Src homology phosphotyrosine phosphatase (SHP2) at the tension and compression sides of the teeth in mouse models. METHODS: A total of 55 C57B/6 mice (10 weeks old) were divided into 3 groups...

INTRODUCTION: A routine diagnosis of a patient's breathing status performed by an orthodontist normally includes visual assessment, medical history, clinical examination of habitual lip posture, size and shape of the nostrils, reflex control of the alar muscle and respiratory tests, and the dental mirror test. The objective of this study was to test the recognition of mouth breathers in young persons by an orthodontist and agreement with an otolaryngologist's reference diagnosis when routine assessments were carried out...

INTRODUCTION: We investigated whether ACTN3, ENPP1, ESR1, PITX1, and PITX2 genes which contribute to sagittal and vertical malocclusions also contribute to facial asymmetries and temporomandibular disorders (TMD) before and after orthodontic and orthognathic surgery treatment. METHODS: One hundred seventy-four patients with a dentofacial deformity were diagnosed as symmetric or subdivided into 4 asymmetric groups according to posteroanterior cephalometric measurements...

INTRODUCTION: The aim of this study was to evaluate the effect of low-level laser irradiation applied at 3-week intervals on orthodontic tooth movement and pain associated with orthodontic tooth movement using self-ligating brackets. METHODS: Twenty-two patients (11 male, 11 female; mean age, 19.8 ± 3.1 years) with Angle Class II Division 1 malocclusion were recruited for this split-mouth clinical trial; they required extraction of maxillary first premolars bilaterally...

INTRODUCTION: Pregnancy in adolescence has long-term consequences that can negatively influence oral conditions. In this study, we aimed to assess malocclusion in deciduous dentition and its association with prolonged breastfeeding, pacifier use, and perinatal health indicators pertaining to the periods immediately before and after birth. METHODS: This cross-sectional study was nested in a cohort of adolescent mothers who became pregnant from 13 to 19 years of age (mean age, 17...

INTRODUCTION: Although many attempts have been made to simulate orthodontic tooth movement using the finite element method, most were limited to analyses of the initial displacement in the periodontal ligament and were insufficient to evaluate the effect of orthodontic appliances on long-term tooth movement. Numeric simulation of long-term tooth movement was performed in some studies; however, neither the play between the brackets and archwire nor the interproximal contact forces were considered...

INTRODUCTION: An electromechanical device was used to experimentally characterize the movement of a single tooth within the periodontal ligament space. The force magnitude leading to the complete compression of the periodontal ligament is considered a critical force and is designated Fc. We investigated the effectiveness of the electromechanical device to repeatedly determine the critical force magnitude Fc. METHODS: The study comprised 12 tests conducted on 11 subjects...

INTRODUCTION: The purpose of this 2-arm parallel trial was to assess the effects of pulsed electromagnetic field (PEMF) on the reduction of pain caused by initial orthodontic tooth movement. METHODS: Thirty-three female patients (mean age, 16.8 ± 3.8 years) who began orthodontic treatment using fixed appliances were examined. In the pilot study, male patients were less likely to use the PEMF device (epatchQ; Speed Dental, Seoul, Korea) and answer a survey consistently, so eligibility criteria were female patients who were periodontally and systemically healthy at the initiation of treatment and had no history of dental pain in the prior 2 weeks or who used no medications (anti-inflammatory or analgesic drugs) during the experiment period...
