Effects of ultrasonic, electric, and manual toothbrushes on subgingival plaque composition in orthodontically banded molars
Introduction Orthodontic appliances hinder mechanical plaque control. In this study, we evaluated the effect of self-performed supragingival plaque removal with ultrasonic, electric, and manual toothbrushes on subgingival plaque composition in…

In-vitro study of the cellular viability and nitric oxide production by J774 macrophages with ceramic, polycarbonate, and polyoxymethylene brackets
Introduction Studies show that ceramic brackets are chemically inert in the oral cavity, whereas polycarbonate and polyoxymethylene brackets can degrade, releasing bisphenol-A and formaldehyde, respectively. In addition to the traditional…
Morphologic quantification of the maxilla and the mandible with cone-beam computed tomography
Introduction The purpose of this pilot study was to use cone-beam computed tomography (CBCT) to determine the volumes of the maxilla and the mandible in subjects with skeletal Class I,…
Pulp vitality after rapid palatal expansion
Introduction Although it has been suggested that orthodontic treatment might lead to changes in the dental pulp, no clinical study has attempted to investigate the incidence of pulp necrosis after…
Mechanical properties of coated superelastic archwires in conventional and self-ligating orthodontic brackets
Introduction Coated archwires have been introduced to improve esthetics during orthodontic treatment. Our aim was to investigate the mechanical properties of coated superelastic archwires compared with conventional superelastic archwires with…
Proper mesiodistal angles for microimplant placement assessed with 3-dimensional computed tomography images
Introduction To provide information about placement sites and angulations of microimplants between tooth roots, we analyzed 3-dimensional computed tomography images from 25 patients. Methods The patients in the sample had…
Clinical and microbiological findings at sites treated with orthodontic fixed appliances in adolescents
Introduction Fixed orthodontic appliances can alter the subgingival microbiota. Our aim was to compare the subgingival microbiota and clinical parameters in adolescent subjects at sites of teeth treated with orthodontic…
Pretreatment characteristics associated with orthodontic treatment duration
Introduction Pretreatment characteristics can assist orthodontists in accurately estimating treatment duration. Methods This case-control study identified 400 patients, 9 to 18 years of age. Short treatment duration was 20 months…
Survival analysis of orthodontic mini-implants
Introduction Survival analysis is useful in clinical research because it focuses on comparing the survival distributions and the identification of risk factors. Our aim in this study was to investigate…
Apical root resorption in orthodontic patients with en-masse maxillary anterior retraction and intrusion with miniscrews
Introduction The purposes of this retrospective study were to investigate the apical root resorption of maxillary incisors in orthodontic patients with en-masse maxillary anterior retraction and intrusion with miniscrews and the factors…
Longitudinal changes in mandibular arch posterior space in adolescents with normal occlusion
Introduction The purpose of this study was to investigate the changes of available mandibular space in the posterior dental arch of teenagers from 13 to 18 years old. Methods Longitudinal…
Results of a survey-based study to identify common retention practices in the United States
Introduction The purpose of this descriptive study was to use a carefully constructed, pilot-tested survey instrument to identify the most common orthodontic retainers and retention protocols prescribed in the United…
Impact of facial asymmetry in visual perception: A 3-dimensional data analysis
Introduction The aim of this controlled study was to analyze the degree and localization of 3-dimensional (3D) facial asymmetry in adult patients with cleft lip and palate (CLP) compared with…
Editor’s Summary and Q&A
Introduction Miniscrew impants as temporary anchorage devices (TADs) are becoming more popular in orthodontic tretment. Their ease of use allows orthodontists to place them in locations in the mouth that…
Commentary
I congratulate the authors on a well-designed survey identifying common retention practices in the United States. However, I remind readers that this article describes what orthodontists do. The next step…
Retrospective cone-beam computed tomography evaluation of temporary anchorage devices
Introduction Miniscrew impants as temporary anchorage devices (TADs) are becoming more popular in orthodontic tretment. Their ease of use allows orthodontists to place them in locations in the mouth that…
Editor’s Summary and Q&A
