Precision of manual landmark identification between as-received and oriented volume-rendered cone-beam computed tomography images
Introduction The objective of this study was to evaluate the effect of the orientation of cone-beam computed tomography (CBCT) images on the precision and reliability of 3-dimensional cephalometric landmark identification….
Cone-beam computed tomographic evaluation of the long-term effects of orthodontic retainers on marginal bone levels
Introduction Fixed retainers are widely used after orthodontic treatment, sometimes for extended periods, despite insufficient knowledge of their possible long-term adverse effects on the periodontium. The aim of this study was…
Effect of piezocision on root resorption associated with orthodontic force: A microcomputed tomography study
Introduction The purpose of this study was to investigate the effect of piezocision on orthodontically induced inflammatory root resorption. Methods Fourteen patients were included in this split-mouth study; 1 side…
Orthodontic postgraduate education: A global perspective
Orthodontic education is often questioned when it is obtained from unfamiliar institutions. The intent of this book is to answer the questions related to this uncertainty; moreover, it gives the…
Matched analysis for paired binary data (McNemar test)
Sometimes we are interested in comparing pairs of observations within the same subjects. Then we should bear in mind that those observations are not independent and should be treated accordingly. Let…
Displacement and stress distribution by different bone-borne palatal expanders with facemask: A 3-dimensional finite element analysis
Introduction The purpose of this study was to analyze displacement and stress distribution in the maxilla during maxillary expansion followed by protraction using bone-borne and conventional tooth-borne palatal expanders and…
Cephalometric landmark identification consistency between undergraduate dental students and orthodontic residents in 3-dimensional rendered cone-beam computed tomography images: A preliminary study
Introduction The aim of this study was to compare 3-dimensional landmark consistency and precision in skeletal structures in groups with different levels of experience with 2-dimensional cephalometrics. Methods Sixteen observers,…

Effects of casein phosphopeptide-amorphous calcium phosphate application after interproximal stripping on enamel surface: An in-vivo study
Introduction The aim of this study was to investigate the effects of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) application after interproximal stripping on enamel surface structures in vivo. Methods Fifteen patients with…
Quantitative evaluation of maxillary alveolar cortical bone thickness and density using computed tomography imaging
Introduction Primary stability is essential to the success of orthodontic mini-implants (OMIs) and heavily depends on the mechanical retention between OMIs and their supporting bone. Alveolar cortical bone commonly serves…
Effects of local platelet-rich plasma injection on the rate of orthodontic tooth movement in a rat model: A histomorphometric study
Introduction The aims of this study were to determine the effects of different concentrations of platelet-rich plasma (PRP) on alveolar bone density and orthodontic tooth movement. Methods Seventy-six rats were…
Influence of quality of life, self-perception, and self-esteem on orthodontic treatment need
Introduction In this study, we aimed to assess the relationship between normative and perceived orthodontic treatment need associated with quality of life, self-esteem, and self-perception. Methods The sample included 248…
Assessing the feasibility of yttria-stabilized zirconia in novel designs as mandibular anterior fixed lingual retention after orthodontic treatment
Introduction The purpose of this study is to explore the feasibility of yttria-stabilized zirconia (Y-TZP) in fixed lingual retention as an alternative to stainless steel. Methods Exploratory Y-TZP specimens were…
Early orthodontic treatment for Class III malocclusion: A systematic review and meta-analysis
Introduction Class III malocclusion affects between 5% and 15% of our population. The 2 most common dilemmas surrounding Class III treatment are the timing of treatment and the type of…
Indirect vs direct bonding of mandibular fixed retainers in orthodontic patients: Comparison of retainer failures and posttreatment stability. A 2-year follow-up of a single-center randomized controlled trial
Introduction The objectives of this 2-arm parallel trial were to compare the numbers of failures of mandibular fixed retainers bonded with indirect and direct methods and to investigate the posttreatment…
