Dental development in children with mild-to-moderate hypodontia
Introduction The aim of this study was to compare dental development in a group of children with mild-to-moderate hypodontia with a matched group. Methods A study group of 70 children…

Do long-term changes in relative maxillary arch width affect buccal-corridor ratios in extraction and nonextraction treatment?
Introduction Our aims were to evaluate long-term maxillary arch width changes in orthodontic patients treated with and without premolar extractions and to provide a potential link to the buccal-corridor ratios….
Comparison of overjet among 3 arch types in normal occlusion
Introduction The purposes of this study were to examine the amounts of overjet in the anterior and posterior segments of 3 arch forms by using facial axis points on 3-dimensional…
Does psychological well-being influence oral-health-related quality of life reports in children receiving orthodontic treatment?
Introduction Although the associations between oral biologic variables such as malocclusion and oral-health-related quality of life (OHRQOL) have been explored, little research has been done to address the influence of…
Effect of fixed appliances on oral malodor
Introduction The objective of this study was to evaluate the effect of fixed appliances on oral malodor. Methods Forty-one patients participated in this study. They were randomized into 2 groups:…
Comparison of arch forms between Egyptian and North American white populations
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…
Physical properties of root cementum: Part 16. Comparisons of root resorption and resorption craters after the application of light and heavy continuous and controlled orthodontic forces for 4, 8, and 12 weeks
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…
Dental and skeletal outcomes for Class II surgical-orthodontic treatment: A comparison between novice and experienced clinicians
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…
Permutation method for evaluating topographic craniofacial correlations
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….
Heuristic reasoning and cognitive biases: Are they hindrances to judgments and decision making in orthodontics?
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…
Effect of nicotine on orthodontic tooth movement in rats
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…
Effect of rapid maxillary expansion and transpalatal arch treatment associated with deciduous canine extraction on the eruption of palatally displaced canines: A 2-center prospective study
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)…
Mechanical strain at alveolar bone and circummaxillary sutures during acute rapid palatal expansion
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…
Relationship between bilateral congenital absence of maxillary lateral incisors and anterior tooth width
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,…
Cranial base foramen location accuracy and reliability in cone-beam computerized tomography
Introduction The purpose of this study was to evaluate the reliability and accuracy in locating several different foramina in the cranial base by using cone-beam computerized tomography (CBCT) images for…
Residents’ journal review
Short term outcomes with early protraction facemask use Mandall N, DiBiase A, Littlewood S, Nute S, Stivaros N, McDowall R, et al. Is early Class III protraction facemask treatment effective? A…
When patients don’t pay
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…
An endless discussion
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…
Authors’ response
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…
Informed consent and open-bite correction
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…
