It’s just a phase
A reader wrote me the following. Larry, do you have any insight into the gray area dealing with the transition from phase 1 (early treatment) to phase 2 (secondary treatment)?…
Analysis of the maxillary dental arch after rapid maxillary expansion in patients with unilateral complete cleft lip and palate
Introduction Although rapid maxillary expansion has been extensively studied in noncleft patients, scarce evidence of maxillary effects is found for patients with oral clefts. Our objective was to evaluate the…
Asymmetric molar distalization with miniscrews to correct a severe unilateral Class III malocclusion
Asymmetries are among the most challenging problems in orthodontics. Proper diagnosis is critical to discern first whether the asymmetry is dental or skeletal. If it is dental, one must then…
Role of myosin 1H gene polymorphisms in mandibular retrognathism
Introduction Mandibular retrognathism may be the result of a developmental abnormality or the unfavorable positional relationship of developing jaws. Several lines of evidence suggest that muscles are known to have…
Influence of TNF-α-308 G/A gene polymorphism on temporomandibular disorder
Introduction Tumor necrosis factor alpha (TNF-α) levels are significantly upregulated in the synovial fluid of patients with temporomandibular joint disorder (TMD). The TNF-α influences pain generation and maintenance. Therefore, the…
Relationship of craniofacial morphology in 3-dimensional analysis of the pharynx
Introduction Pharynx dimensions may vary according to the position and morphology of the mandible. The aim of this study was to test the hypothesis that craniofacial morphology affects pharyngeal volume…
Common 3-dimensional coordinate system for assessment of directional changes
Introduction The aims of this study were to evaluate how head orientation interferes with the amounts of directional change in 3-dimensional (3D) space and to propose a method to obtain…
Effects of maxillary protraction therapy on the pharyngeal airway in patients with repaired unilateral cleft lip and palate: A 3-dimensional computed tomographic study
Introduction The purposes of this study were to assess the effects of maxillary protraction therapy on the pharyngeal airways in patients with repaired unilateral cleft lip and palate (UCLP) 3…
Effect of polyvinylsiloxane material and impression handling on the accuracy of digital models
Introduction The objective of this study was to evaluate the accuracy and reliability of measurements on digital models obtained by scanning impressions 5, 10, and 15 days after they were made…
Effects of fixed orthodontic treatment on nickel and chromium levels in gingival crevicular fluid as a novel systemic biomarker of trace elements: A longitudinal study
Introduction Nickel and chromium might induce hypersensitivity. Therefore, they are of interest to orthodontists. Gingival crevicular fluid (GCF) is highly relevant to orthodontic treatments and might reflect systemic changes associated…
Maxillary first premolar inclination in 8- to 11-year-old children: An observational cross-sectional study on panoramic radiographs
Introduction In this study, we examined first premolar inclination in a large sample. Methods First premolar inclination, canine inclination, and mesiodistal location were measured on 797 panoramic radiographs of orthodontically…
Predicting improvement of postorthodontic white spot lesions
Introduction Patients undergoing orthodontic treatment are at greater risk for developing white spot lesions (WSLs). Although prevention is always the goal, WSLs continue to be a common sequela. For this…
Effectiveness of orthodontic treatment with functional appliances on maxillary growth in the short term: A systematic review and meta-analysis
Introduction The aim of this systematic review was to evaluate the treatment effects on maxillary growth of removable functional appliances that advance the mandible to a more forward position in…
Fixed functional appliances with multibracket appliances have no skeletal effect on the mandible: A systematic review and meta-analysis
Introduction Our aim was to assess the skeletal mandibular changes (anteroposterior and vertical) in circumpubertal patients with fixed functional appliances installed on multibracket appliances compared with untreated patients. Methods An…
It’s a rough sport
Your business manager has repeatedly advised you to update your Web site. You have recently added a new associate to your practice, so you agree that a revision is indeed…
Residents’ journal review
Light-curable fluoride varnish may be effective in preventing enamel demineralization during orthodontic treatment for up to 4 months Mehta A, Paramshivam G, Chugh VK, Singh S, Halkai S, Kumar S. Effect…
Start at the beginning
A nostalgic aura haunted me when I read Steven J. Lindauer’s Centennial Guest Editorial, “Where are we going” (Am J Orthod Dentofacial Orthop 2015;148:708-9). I would like to remark. Advances…
Authors’ response
Thank you for spotting an error in the printed formula (Chung DD, Wolfgramm R. Maxillary arch perimeter prediction using Ramanujan’s equation for the ellipse. Am J Orthod Dentofacial Orthop 2015;147;235-41)….
Use of Ramanujan’s equation of ellipse to determine arch perimeter
We want to congratulate Drs Chung and Wolfgramm for their article in the February 2015 issue shining a light on the use of a mathematical equation for ellipse to evaluate…
