Introduction The aim of this study was to evaluate the morphologic differences in the mandibular arches of Egyptian and North American white subjects. Methods The sample included 94 Egyptian subjects…
Introduction Orthodontic force duration can affect the severity of root resorption. The aim of this clinical study was to investigate the amounts of root resorption volumetrically after the application of…
Introduction The information that details dental changes accompanying presurgical and postsurgical orthodontic treatment during orthognathic surgery treatment is disappointing and results in less than ideal surgical change, but it is…
Introduction Correlations between cephalometric measurements are frequently assumed to represent biologic associations. However, a significant portion of such correlations might arise from purely geometric dependencies, when measurements share common landmarks….
Studies show that our brains use 2 modes of reasoning: heuristic (intuitive, automatic, implicit processing) and analytic (deliberate, rule-based, explicit processing). The use of intuition often dominates problem solving when…
Introduction Although the detrimental health effects of cigarettes are well known, many people, including some orthodontic patients, continue to smoke. Nicotine can affect bone resorption and apposition. Therefore, the aim…
Introduction Our aim was to investigate the effect of rapid maxillary expansion and transpalatal arch therapy combined with deciduous canine extraction on the eruption rate of palatally displaced canines (PDCs)…
Introduction Palatal expansion can potentially affect alveolar bone and circummaxillary sutures. In this study, we characterized their mechanical strain during acute expansion. Methods Eight 3- and 6-month-old fresh pig heads…
Introduction The objective of this study was to assess the relationship between anterior tooth width and the presence or absence of maxillary lateral incisors. Methods Reference models of 106 subjects,…

In retrospect, you realize you should have seen this coming. After 30 months of complex orthodontic therapy, your young patient’s previously impacted maxillary left canine is fully corrected. His occlusion…
I want to make a few observations about the recent discussion on malocclusions and temporomandibular disorders (TMDs) (Point/Counterpoint. Am J Orthod Dentofacial Orthop 2011;139:10-6). I agree that trying to improve…
We appreciate Drs Mangano and Mangano’s interest in our article. We agree with their remark that, before undertaking any prospective clinical trial (either randomized or nonrandomized), a power analysis for…
The online article, “Long-term stability of surgical-orthodontic open-bite correction” (Maia FA, Janson G, Barros SE, Maia NG, Chiqueto K, Nakamura AY. Am J Orthod Dentofacial Orthop 2010;138:254.e1-10), and the associated…
We read with interest the article in the November 2010 issue on tooth color after orthodontic treatment (Karamouzos A, Athanasiou AE, Papadopoulos MA, Kolokithas G. Tooth-color assessment after orthodontic treatment:…
Cranial base foramen location accuracy and reliability in cone-beam computerized tomography Manuel O. Lagravère, Jillian M. Gordon, Carlos Flores-Mir, Jason Carey, Giseon Heo, and Paul W. Major. Am J Orthod…
We appreciate the interest in our article. Initially, a Planas appliance was placed, which allowed raising of the bite provided by the tracks of the maxillary and mandibular appliances due…
