You enjoy teaching in a nearby orthodontic specialty program. One morning, your department chair calls you up to her office and asks whether you would consider heading the department’s admissions…
Ankylosed maxillary incisor with severe root resorption treated with a single-tooth dento-osseous osteotomy, vertical alveolar distraction osteogenesis, and mini-implant anchorage
Dentoalveolar ankylosis interferes with the vertical growth of the alveolar process, which can lead to an open bite, an unesthetic smile, and occlusal disharmony. This case report presents a new…

Although the writer has the right to choose the title and content of his letter, it seems as if the purpose of the letter is not to allow the authors…
Statistical errors in a recent article: Sella turcica in patients with type 1 diabetes
I read with interest the article by Bavbek and Dincer (Dimensions and morphologic variations of sella turcica in type 1 diabetic patients. Am J Orthod Dentofacial Orthop 2014;145:179-87). Although it…
Maxillary arch width and buccal corridor changes with orthodontic treatment
With great interest and respect, we read the research reported by Anna H. Meyer et al (Meyer AH, Woods MG, Manton DJ. Maxillary arch width and buccal corridor changes with orthodontic…
Author’s response
Thank you to Drs Yan and Tian for the comments and question regarding Part 2 of our work regarding arch-width and buccal corridor changes. Drs Yan and Tian suggested that…

We are grateful to the Dr Todd Connell for his careful reading and relevant comment on our article. We agree that there was a miswriting in the Abstract and the…
Reproducibility and accuracy of linear measurements on dental models derived from cone-beam computed tomography compared with digital dental casts
Introduction The aim of this study was to determine the reproducibility and accuracy of linear measurements on 2 types of dental models derived from cone-beam computed tomography (CBCT) scans: CBCT…
Dental arch dimensional changes
Please review the article entitled “Dental arch dimensional changes after adenotonsillectomy in prepubertal children” (Caixeta ACP, Andrade I Jr, Pereira TBJ, Franco LP, Becker HMG, Souki BQ. Am J Orthod…
Pitching speed
X-rays were discovered in 1895, closely followed in 1898 by the discovery of the radioactive properties of radium. Almost immediately, a flood of medical products were introduced, marketed, and purported…
Morphologic variability of nonsyndromic operated patients affected by cleft lip and palate: A geometric morphometric study
Introduction In this study, we compared patterns of morphologic variations of the craniofacial skeleton between patients affected by clefts who were operated on and unaffected subjects, aiming to discuss possible…
Three-dimensional upper-airway changes with maxillomandibular advancement for obstructive sleep apnea treatment
Introduction Airway size increases are associated with maxillomandibular advancement (MMA) surgery and improvement or elimination of obstructive sleep apnea (OSA). The 3-dimensional morphologic, volumetric, height, cross-sectional surface area, and diameter…
Mastication markedly affects mandibular condylar cartilage growth, gene expression, and morphology
Introduction Mandibular growth is believed to be strongly related to mastication. Furthermore, mandibular condylar cartilage is known to be derived from neural crest cells. We examined whether the degree of…
Thermomechanical properties of nickel-titanium closed-coil springs and their implications for clinical practice
Introduction The aim was to study nickel-titanium closed-coil springs in a clinically relevant test setting with respect to the accuracy of the “preactivation” for nickel-titanium closed-coil springs application and whether…

Arbitration agreement By signing this agreement, you are: 1. Waiving your statutory right to a jury trial, and 2. Agreeing to arbitrate all claims arising out of or 3. Related…
Case-control studies: Part 2
In the previous article, I defined the case-control study and discussed issues regarding the selection of controls. In this second article devoted to case-control studies, I will discuss bias and…
Prediction of 3-dimensional pharyngeal airway changes after orthognathic surgery: A preliminary study
Introduction Recent studies have shown some contradictory results when evaluating the consequences of orthodontic-surgical treatments on the pharyngeal airway. Therefore, the purpose of this study was to correlate the amount…
A “midline dilemma” in an adult mutilated dentition
Orthodontic treatment for adult patients who have mutilated dentitions can be clinically challenging. A 58-year-old man with several occlusally abraded teeth, a congenitally missing maxillary lateral incisor, and prior implant…
Mandibular incisor inclination, tooth irregularity, and gingival recessions after Herbst therapy: A 32-year follow-up study
Introduction The aim of this study was to analyze the very long-term results after Herbst treatment with respect to changes in the mandibular incisor segment: incisor inclination, incisor alignment, and…
Evaluation of pharyngeal airway space changes after bimaxillary orthognathic surgery with a 3-dimensional simulation and modeling program
Introduction The aims of this study were to use 3-dimensional simulation and modeling programs to evaluate the effects of bimaxillary orthognathic surgical correction of Class III malocclusions on pharyngeal airway…
