This report describes the orthodontic treatment of a woman, aged 34 years 2 months, with several missing teeth and atrophic mandibular first molar extraction sites. We had planned to close…
Introduction The aims of this study were to investigate the relationship between dental age and maxillary canine displacement with 2 methods, to study differences in dental development between the displaced…
Introduction The aim of this study was to investigate the frequency of dental anomalies in orthodontic patients with different patterns of third-molar agenesis, comparing them with patients without third-molar agenesis….
Introduction The purpose of this study was to compare the soft-tissue profiles of matched Class I adolescent European Americans and Mexican Americans. The secondary aim was to explain profile differences…
Introduction Posterior unilateral crossbite treatment is usually oriented to the maxilla. The aims of this retrospective investigation were (1) to study the maxillary arch morphology in patients with posterior unilateral…
Introduction With the recent changes in scoring of the National Board Dental Examinations and grading systems in some dental schools, ranking prospective orthodontic applicants has become a challenge. Methods A…
Introduction Evidence comparing periodontal conditions in orthodontic patients who regularly use or do not use dental floss is scarce. Methods The subjects were 330 patients who had been under fixed…
Introduction Cortical bone thickness and bone depth are important factors when placing an orthodontic mini-implant. The objective of this study was to investigate both variables for the palatal alveolar process….
Introduction The purpose of this study was to examine the effect of a new cryopreservation method with a magnetic field on periodontal regeneration in vitro and in vivo. Methods Human periodontal ligament…
Introduction Bone-anchored maxillary protraction has been shown to be an effective treatment modality for the correction of Class III malocclusions. The purpose of this study was to evaluate 3-dimensional changes…
Introduction In this study, we assessed the changes in bisphenol A (BPA) levels in saliva and urine after placing lingual bonded retainers. Methods Liquid chromatography/mass spectrometry was used to examine…
Introduction The use of space maintainers after the premature loss of deciduous molars is routine in pediatric dentistry. However, there is a need for evidence offering a better scientific basis…
Introduction Microcomputed tomography offers a unique opportunity to accurately examine orthodontically induced inflammatory root resorption. The aims of this study were to quantify, in 3 dimensions, the amount of root…
