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…
