Author’s response
We thank Professor Peck and the Editor for the opportunity of discussion. Approaching this research, we considered it to be unethical not to treat patients at risk for ectopically erupting…
Study clubs
In a recent editorial, editor Vincent Kokich wrote about the importance of study clubs for life-long learning (The key to adult orthodontics. Am J Orthod Dentofacial Orthop 2011;139:289). Our study…
Problematic sample in the study of interception of palatally displaced canines
The March 2011 cover article (Bonetti GA, Zanarini M, Parenti SI, Marini I, Gatto MR. Preventive treatment of ectopically erupting maxillary permanent canines by extraction of deciduous canines and first…
Heuristic reasoning and cognitive biases
Bravo! Encore! The Special Article on heuristic reasoning in the March 2011 issue is very interesting and thought-provoking with excellent use of limited space (Hicks EP, Kluemper GT. Heuristic reasoning…
How good are you?
As orthodontists, most of us believe that we are among the best in our community at what we do—straightening teeth. Of course, we know that alignment is not the only…

Suppose for a minute that you have had some trouble with the state board of dentistry in the jurisdiction in which you practice. Maybe it was only 1 or 2…
Impacted maxillary central incisor: Surgical exposure and orthodontic treatment
This case report describes the treatment of a patient with a horizontally impacted maxillary central incisor, a canine in the same quadrant, and an inclusion tendency. Due to severe crowing…
Developing skeletal Class III malocclusion treated nonsurgically with a combination of a protraction facemask and a multiloop edgewise archwire
For a girl, aged 12 years 3 months, with a skeletal Class III malocclusion, negative overjet, severe maxillary crowding, and hyperdivergent pattern, orthognathic surgery combined with orthodontic treatment is often…
Displacement pattern of the maxillary arch depending on miniscrew position in sliding mechanics
Introduction This clinical study was performed to evaluate the anteroposterior and vertical displacement patterns of the maxillary teeth in sliding mechanics depending on the position of interradicular miniscrews after the…
Accuracy and reliability of cone-beam computed tomography measurements: Influence of head orientation
Introduction The purpose of this research is to determine the accuracy and reliability of measurements obtained from 3-dimensional (3D) cone-beam computed tomography (CBCT) for different head orientations. Methods Stainless steel…
Stability of Class II treatment with an edgewise crowned Herbst appliance in the early mixed dentition: Skeletal and dental changes
Introduction The objectives of this research were to assess skeletal and dental changes in patients with Class II malocclusion treated with the edgewise crowned Herbst appliance in the early mixed…
Accidental swallowing of orthodontic expansion appliance key
Ingestion of a foreign object, including a dental object, can lead to a trip to the emergency room. This article describes the accidental swallowing of a key that was used…
Agreement between the index of complexity, outcome, and need and the dental and aesthetic components of the index of orthodontic treatment need
Introduction This was a cross-sectional study to investigate the agreement between assessments of orthodontic treatment need of the index of complexity, outcome, and need (ICON) and the index of orthodontic…
Force system evaluation of symmetrical beta-titanium T-loop springs preactivated by curvature and concentrated bends
Introduction The objective of this research was to compare the effect of preactivation on the force system of beta-titanium T-loop springs (TLSs). Methods Twenty TLSs with dimensions of 6 ×…
Effects of stress relaxation in beta-titanium orthodontic loops
Introduction This study evaluates the changes in the force system of the beta-titanium T-loop spring (TLS) caused by stress relaxation. Methods Ninety TLSs with dimensions of 6 × 10 mm,…
Effect of loading force on the dissolution behavior and surface properties of nickel-titanium orthodontic archwires in artificial saliva
Introduction For orthodontic applications, equiatomic nickel-titanium (NiTi) wires are used to level and align the teeth under bending conditions in the oral environment for long periods. The aim of study…
