Introduction Our objective was to determine the perception of smile esthetics among orthodontists and laypeople with respect to asymmetries in the maxillary canines’ gingival margins in full-face and close-up smile…
To all my readers: Thanks for sending in topics that you want to see covered in this column. So far, they have fallen into 4 categories, and for brevity’s sake,…
Introduction Root resorption is an undesirable sequela of orthodontic treatment. It is necessary to establish sensitive methods for identification of teeth at risk for resorption. The x-ray is the traditional…
Introduction The objective of this study was to determine whether dental calcification can be used as a first-level diagnostic tool for assessment of skeletal maturity. Methods A total of 150…
Introduction This study was a cephalometric evaluation of the growth changes in untreated subjects with minimal overbite at 4 time points during 4 developmental stages from the early mixed dentition…
This article reports the comprehensive, interdisciplinary treatment of a 50-year-old periodontally compromised adult patient with multiple missing posterior teeth. After initial periodontal treatment, the maxillary first molars and right central…
Orthodontic space closure during treatment of skeletal Class III malocclusions Kim JW, Lee NK, Yun PY, Moon SW, Kim YK. Postsurgical stability after mandibular setback surgery with minimal orthodontic preparation…
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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
