An ounce of prevention
Mrs Greene is your last patient of the week. Despite her Class II dentoskeletal relationship, she is an attractive middle-aged woman who was referred by a top-notch periodontist to upright…
Authors’ response
We want to thank Jingyu Li et al for the feedback on our study evaluating asymmetries in Class II subdivision malocclusions using cone-beam computed tomography (CBCT). Dr Li brought up a…
Timely relocation of subapically impacted maxillary canines and replacement of an ankylosed mandibular molar are the keys to eruption disturbances in a prepubertal patient
Eruption disturbances such as impaction and ankylosis complicate orthodontic treatment because soft-tissue and hard-tissue considerations must be taken into account. Treatment is further complicated when such eruption disturbances occur in…
Asymmetries evaluated with cone-beam computed tomography
With great interest and respect, I read the research reported by Minich et al (Minich CM, Araújo EA, Behrents RG, Buschang PH, Tanaka OM, Kim KB. Evaluation of skeletal and dental…
Accurate registration of cone-beam computed tomography scans to 3-dimensional facial photographs
Introduction Registering a 3-dimensional (3D) facial surface scan to a cone-beam computed tomography (CBCT) scan has various advantages. One major advantage is to compensate for the inaccuracy of the CBCT…
Enhancing CONSORT compliance for improved reporting of randomized controlled trials
When one is making clinical decisions, the evidence-based dentistry approach amalgamates the best available evidence, clinical expertise, and patients’ preferences and values. High-quality randomized controlled trials (RCTs) are an integral…
Perceptions of midline deviations among different facial types
Introduction The correction of a deviated midline can involve complicated mechanics and a protracted treatment. The threshold below which midline deviations are considered acceptable might depend on multiple factors. The…
Maxillary arch width and buccal corridor changes with orthodontic treatment. Part 1: Differences between premolar extraction and nonextraction treatment outcomes
Introduction In this retrospective study, we examined and compared the pretreatment and posttreatment arch widths and buccal corridor changes in subjects who had received orthodontic treatment either with or without…
Cephalometric investigation of craniomaxillofacial structures during the prenatal period: A cadaver study
Introduction We aimed to investigate the morphometric development of the cranial base and its related structures, and their growth rate changes from the ninth gestational week to full term in…
Comparison of cephalometric measurements and cone-beam computed tomography-based measurements of palatal bone thickness
Introduction The purpose of this study was to determine the relationships between cephalometric measurements and cone-beam computed tomography-based measurements of the palatal bone thickness. Methods Thirty sets of cone-beam computed…
Reliability of upper airway linear, area, and volumetric measurements in cone-beam computed tomography
Introduction Our objective was to assess the intraexaminer and interexaminer reliabilities of upper airway linear, area, and volumetric measurements in cone-beam computed tomography. Methods Cone-beam computed tomography scans of 12…
Macadamias, pistachios, and filberts
Thanks to all of you who wrote in with questions or problems. Several of our readers sent the following related incidents. They all deal with the issue of how we…
Introduction to observational studies: Part 2
I will continue the introduction to observational studies by explaining some of the common nomenclature that might also be encountered in randomized controlled trials. We often use the terms exposure…
Accuracy, reproducibility, and time efficiency of dental measurements using different technologies
Introduction Historically, orthodontists have taken dental measurements on plaster models. Technological advances now allow orthodontists to take these measurements on digital models. In this study, we aimed to assess the…
Impact of metal and ceramic fixed orthodontic appliances on judgments of beauty and other face-related attributes
Introduction Physical attributes, behavior, and personal ornaments exert a direct influence on how a person’s beauty and personality are judged. The aim of this study was to investigate how people…
Dimensions and morphologic variations of sella turcica in type 1 diabetic patients
Introduction Some chronic diseases are associated with changes in the morphology of sella turcica, and type 1 diabetes is the most common chronic disease in children and adolescents. Therefore, the…
Evaluation of cone-beam computed tomography in the diagnosis of simulated small osseous defects in the mandibular condyle
Introduction In this study, we investigated the impact of defect size and scan voxel size on the accuracy of cone-beam computed tomography (CBCT) diagnoses of simulated condylar defects and assessed…
Antimicrobial effect of Melaleuca alternifoliadental gel in orthodontic patients
The aim of this study was to evaluate the antimicrobial effect and sensorial analysis of the gel developed with the essential oil of Melaleuca alternifolia. Thirty-four volunteers, divided into 2…
Long-term occlusal changes assessed by the American Board of Orthodontics’ model grading system
Introduction The purpose of this study was to assess the long-term posttreatment changes in all criteria of the American Board of Orthodontics’ (ABO) model grading system. Methods We used plaster…
An evidence iceberg
I agree with Dr Kokich’s editorial in the September 2013 issue of the AJO-DO , urging us to join the orthodontic practice-based research network and the higher priority for the…
