Introduction This study investigated correlations between airway size and age, sex, and skeletal patterns; identified airway change trends; and measured volumetric norms in children via cone-beam computed tomography. Methods Four…
Introduction This study aimed to determine whether single nucleotide polymorphisms in the growth hormone receptor ( GHR ) and insulin-like growth factor 2 receptor ( IGF2R ) genes are associated…
Introduction External apical root resorption is nearly ubiquitous in people treated orthodontically. This study predicted the extent of external apical root resorption by the vector of the incisor movement. Methods…
Introduction This retrospective pilot study assessed the pre- and posttreatment lip profile changes among adult patients with Class II Division 1 malocclusion of varied growth patterns and compared these changes…
Objective The objective of this systematic review and meta-analysis was to compare powered and manual toothbrushes for oral hygiene maintenance in orthodontic patients. Methods Electronic databases, including MEDLINE, Scopus, Google…
Introduction Children with attention deficit hyperactivity disorder (ADHD) have more sleep breathing problems and parafunctional oral habits than individuals without ADHD. However, there is scarce information on the correlation between…
Introduction The present study aimed to evaluate the most common urgencies and emergencies in orthodontics during the coronavirus disease 2019 (COVID-19) pandemic and to assess how orthodontists in Brazil were dealing…
Introduction The purpose of this research was to evaluate the esthetic impact of orthodontic treatment need in adolescents. Methods This cross-sectional study was performed with 1172 adolescents aged 12 (n = 638)…
Introduction This research aimed to compare the estimation error of the root axis using 3-dimensional (3D) tooth models at the midtreatment stage between the whole-surface scan (WSS) and lingual-surface scan…
Introduction This study aimed to investigate the effect of digitally designed aligner thickness on the thickness of the corresponding 3-dimensional (3D)-printed aligner. Methods Digitally designed aligners of 3 different thicknesses…
Introduction The primary aim of this study was to investigate and compare perceived pain intensity and oral health–related quality of life (OHRQOL) results during the activation phase of rapid maxillary…
Introduction White spot lesions are a common side effect of orthodontic treatment. This laboratory study aimed to explore the suitability of chlorhexidine hexametaphosphate (CHX-HMP) as a coating for orthodontic elastomeric…
Introduction This study aimed to assess the stability of compensatory treatment of Class III malocclusion in permanent dentition. Methods Thirty-six patients (21 women and 15 men; mean age, 20 years) with…
