Authors’ response
We appreciate the interest of Drs Ye, Li, and Lai in the controversial topic of airway volume assessment with CBCT. Below are our responses to their questions. The aim of…
Evaluating airway volume with CBCT
With interest, we read the Techno Bytes article on analyzing airway volume by using cone-beam computed tomography (CBCT) in the May 2012 issue of the AJO-DO . The authors used…
Esthetic periodontal surgery for impacted dilacerated maxillary central incisors
Clinicians do not frequently see impacted dilacerated maxillary incisors in their patients. When they do, there are several diagnostic and management challenges for correcting root dilacerations. An unfavorable esthetic outcome might…
Three-dimensional ultrashort echo magnetic resonance imaging of orthodontic appliances in the natural dentition
Introduction The purpose of this study was to determine whether ultrashort echo time magnetic resonance imaging technology could be used to image teeth with orthodontic appliances in place. Methods High-resolution…
Functional improvements after orthodontic-surgical reconstruction in a patient with multiple maxillofacial fractures
Patients with multiple craniofacial fractures often suffer from stomatognathic problems after their primary treatment, because administering emergency care is the clinician’s highest priority. Therefore, optimal bone repositioning is sometimes difficult…
Treatment effects of bonded spurs associated with high-pull chincup therapy in the treatment of patients with anterior open bite
Introduction The aim of this prospective clinical study was to investigate the cephalometric changes produced by bonded spurs associated with high-pull chincup therapy in children with Angle Class I malocclusion…
Orthodontic correction of a transposed maxillary canine and first premolar in the permanent dentition
The patient was a 16-year-old Japanese girl whose chief complaints were crowding and transposition of the maxillary canine and first premolar. A setup model was used to preoperatively align the…
Severe facial asymmetry and unilateral lingual crossbite treated with orthodontics and 2-jaw surgery: 5-year follow-up
A 33-year-old woman with severe facial asymmetry and unilateral lingual crossbite was treated with orthodontics combined with differential maxillary impaction and intraoral vertical ramus osteotomy. After 12 months of preoperative…
Bone stress when miniplates are used for orthodontic anchorage: Finite element analysis
Introduction The success rate of miniplates is superior to that of other temporary anchorage devices; nevertheless, the biomechanical behavior of miniplates during orthodontic use is not totally understood. The aim…
Finite element analysis of the effect of force directions on tooth movement in extraction space closure with miniscrew sliding mechanics
Introduction Miniscrews placed in bone have been used as orthodontic anchorage in extraction space closure with sliding mechanics. The movement patterns of the teeth depend on the force directions. To…
Photography in Dentistry: Theory and Techniques in Modern Documentation
It is generally accepted that well-composed images are necessary for proper diagnosis and treatment planning. In their book, Photography in Dentistry: Theory and Techniques in Modern Documentation , Drs Pasquale…
Sample calculations for comparing rates
In a previous article, we outlined the required steps for sample size calculations when comparing 2 proportions. In this article, we will perform a sample calculation for comparisons of 2…
Paying the piper
One of the more vexing problems for new, younger doctors and the senior doctors who employ them concerns restrictive covenants. Most states allow them unless they are found to be…
Deep overbite malocclusion: Analysis of the underlying components
Introduction A deepbite malocclusion should not be approached as a disease entity; instead, it should be viewed as a clinical manifestation of underlying discrepancies. The aim of this study was…
Kinetics of interleukin-6 and chemokine ligands 2 and 3 expression of periodontal tissues during orthodontic tooth movement
Introduction Mechanical loading induces remodeling of the periodontal ligament and the alveolar bone and is mediated by cytokines and chemokines. In this study, we investigated the kinetics of interleukin-6 and…
Molecular detection of Aggregatibacter actinomycetemcomitanson metallic brackets by the checkerboard DNA-DNA hybridization technique
Introduction The purpose of this randomized clinical study was to evaluate the presence of the periodontal pathogen Aggregatibacter actinomycetemcomitans on metallic brackets and the effectiveness of a 0.12% chlorhexidine digluconate…
Effects of buccal corridors on smile esthetics in Japanese and Korean orthodontists and orthodontic patients
Introduction The purpose of this study was to evaluate the influence of the size of buccal corridors on the assessment of attractive smile esthetics by Japanese and Korean orthodontists and…
Dental crowding as a caries risk factor: A systematic review
Introduction The association between dental crowding and dental caries has long been accepted because of increased food accumulation and plaque retention in areas of crowding. The aim of this review…
Reporting quality of abstracts of randomized controlled trials published in leading orthodontic journals from 2006 to 2011
Introduction Optimal reporting of randomized trials and abstracts enhances transparency and facilitates assessment and identification of trials. The purpose of this study was to investigate the quality of reporting of…
Treating obstructive sleep apnea: The case for surgery
Obstructive sleep apnea (OSA) is a chronic, progressive, and potentially life-threatening disorder that can be effectively treated with surgery. It is also a condition that orthodontists see in their offices…
