Introduction A significant objective of orthodontic treatment is to achieve proper and stable tooth positions that involve not only the crowns, but also their roots. However, the current methods of…
Introduction Juvenile idiopathic arthritis in temporomandibular joints (TMJs) is often treated with intra-articular steroid injections, which can inhibit condylar growth. The purpose of this study was to compare simvastatin (a…
Bimaxillary protrusion in a 28-year-old woman was complicated by multiple missing, restoratively compromised, or hopeless teeth. The maxillary right central incisor had a history of avulsion and replantation that subsequently…
Introduction The purpose of this study was to analyze the relationship between the mandibular dental and basal bone arch forms for severe skeletal Class III patients by using 3-dimensional digital…
Introduction Severe incisor root resorption (SIRR) associated with impacted maxillary canines is rare but has important implications. Early diagnosis and treatment are imperative. In this investigation, we aimed to identify…
We report the successful treatment of a woman aged 25 years 3 months with bilateral cleft lip and palate. She had a protruded premaxilla, collapsed posterior segments, wide alveolar defects with oronasal…
Introduction Mechanical interlocking between a mini-implant (MI) and the bone substrate reflects directly on the primary stability achieved. The purposes of this study were to evaluate MI design performance in…
Introduction The purpose of this study was to evaluate craniocervical posture and hyoid bone position in orthodontic patients with temporomandibular joint (TMJ) disc displacement. Methods The subjects consisted of 170…
In orthodontic research, investigators often design studies in which the main response variable is measured repeatedly over time. Compared with cross-sectional designs, repeated-measures designs allow a more definitive evaluation of…
Introduction The aim of this longitudinal 32-year follow-up investigation was to analyze the very long-term effects of Herbst treatment on the dentoskeletal structures. We followed 14 patients from a sample…
Introduction Cone-beam computed tomography (CBCT) gives orthodontists and other dental clinicians 3-dimensional information for planning treatment in the craniofacial region. Often overlooked are incidental findings outside the treatment region of…
How do you explain difficult problems in orthodontics and traumatic injuries to the teeth in an easy and comprehensible way for the clinician? This has been done in a new…
In my risk management courses, a topic I discuss is how to document that you received a patient’s informed consent. In reality, there is a hierarchy of documentation methods. Think…
Introduction Orthognathic patients appear to be increasingly using the Internet to obtain information about their proposed treatment. The aim of this study was to investigate the information that orthognathic patients…
Introduction The aims of this study were to quantitatively evaluate the changes in arch widths and buccolingual inclinations of the posterior teeth after asymmetric rapid maxillary expansion (ARME) and to…
Introduction Our objective was to quantitatively assess and compare the bisphenol A (BPA) released from an orthodontic adhesive using a light-emitting diode device (LED) or a halogen light-curing unit (HLC)…
Effects of surface preparation on shear bond strength Elnafar AA, Alam MK, Hasan R. The impact of surface preparation on shear bond strength of metallic orthodontic brackets bonded with a…
Ms Samson returns to your office to discuss—again—the orthodontic options to address her maxillary anterior crowding. You gave her a diagnosis and several treatment options about a year ago, but…
I was rather taken aback to read an article in the September 2014 issue that used cone-beam computed tomography (CBCT) to measure airway changes in subjects with obstructive sleep apnea….
We wish to thank Dr Yongwen Guo for his interest and thoughtful review of our article in the AJO-DO . The exposures or interventions we used in our study were…
