Introduction This in-vitro study presents the development and validation of an artificial tooth-periodontal ligament-bone complex (ATPBC) and comparison of its behavior with that of rigid dowels during third-order torque simulation….
Introduction The purpose of this study was to analyze the effect of mesiodistal angulation of the maxillary central incisors on the smiling esthetics in young adults. Methods Frontal smile photographs…
Introduction Our objective was to investigate the effect of low-frequency mechanical vibration (LFMV) on the rate of tooth movement, bone volume fraction, tissue density, and the integrity of the periodontal…
Introduction In this study, we evaluated the reproducibility of natural head position for pitch and roll acquired using 3 methods. Methods The participants were 30 Chinese adults (ages, 23-28 years) who…
The approach to orthodontic diagnosis has changed gradually but steadily over the past 2 decades. The shift away from diagnosis based entirely on hard tissue evaluations has been a result of…

Introduction Fluoxetine is a widely used antidepressant. Its various effects on bone mineral density are well described. The aim of this study was to evaluate the effect of fluoxetine on…
In the sciences, scholars emerge from time to time to lay down principles and crystallize the information of their day. Such a scholar was Dr Robert Murray Ricketts (1920-2003) (…
Orthodontic practice results in relatively few patient challenges and litigations. This often leads to a false sense of security and encourages orthodontists to optimize practice management techniques that may be at…
The palate has been reported to be a suitable skeletal anchorage site in adolescents and adults. This article introduces new treatment modalities for correction of sagittal discrepancies by molar protraction…
Introduction The aim of this study was to assess the incidence of white spot lesions (WSLs) in subjects treated with customized lingual multibracket appliances—separately for maxillary anterior teeth 12 to…
Introduction To obtain the balance and harmony of the soft tissue facial profile in orthodontic treatment, it is necessary to identify the characteristics of overlying soft tissues according to the…
This article is a review that enumerates the causes of impaction of the maxillary permanent canines, including hard tissue obstructions, soft tissue lesions, and anomalies of neighboring teeth, and discusses…
As part of the Centennial Celebration of the AJO-DO , approximately 2500 images published in the Journal between 1915 and 2001 have now been identified, scanned, and cataloged. These images…
A mandibular functional shift usually poses a challenge for orthodontists, especially when it is accompanied by a temporomandibular disorder (TMD). Accurate diagnosis and complete elimination of the etiologic factors are…
