Evaluation of maxillary buccal alveolar bone before and after orthodontic alignment without extractions: A cone beam computed tomographic study.

Objectives:: To assess the changes in the maxillary buccal alveolar bone during alignment without extractions. Secondarily, to evaluate the changes in arch dimensions and buccolingual inclinations of teeth and to identify risk factors for bone loss.

Materials And Methods:: Twenty-two adolescents with crowded permanent dentitions were treated without extractions with Damon 3MX brackets.

Soft tissue treatment changes with fixed functional appliances and with maxillary premolar extraction in Class II division 1 malocclusion patients.

Objective: The aim of this study was to compare the soft tissue changes and post-treatment status after complete fixed functional appliance non-extraction and maxillary premolar extraction treatment in patients with Class II division 1 malocclusion.

Materials/methods: The sample consisted of 96 lateral cephalograms of 48 patients, divided into two groups. Group 1 consisted of 23 patients treated with fixed functional appliance associated with fixed appliances, with initial and final mean ages of 12.

Risk factors for respiratory complications after adenotonsillectomy in children with obstructive sleep apnea.

Objective: To identify risk factors for respiratory complications after adenotonsillectomy in children ≤ 12 years of age with obstructive sleep apnea who were referred to the pediatric ICU (PICU).

Methods: A cross-sectional historical cohort study analyzing 53 children after adenotonsillectomy who met predetermined criteria for PICU referral in a tertiary level teaching hospital. The Student's t-test, Mann-Whitney test, and chi-square test were used to identify risk factors.

Postretention stability after orthodontic closure of maxillary interincisor diastemas.

Unlabelled: Anterior spaces may interfere with smile attractiveness and compromise dentofacial harmony. They are among the most frequent reasons why patients seek orthodontic treatment. However, midline diastema is commonly cited as a malocclusion with high relapse incidence by orthodontists.

Intraoral distalizer effects with conventional and skeletal anchorage: a meta-analysis.

Introduction: The aims of this meta-analysis were to quantify and to compare the amounts of distalization and anchorage loss of conventional and skeletal anchorage methods in the correction of Class II malocclusion with intraoral distalizers.

Methods: The literature was searched through 5 electronic databases, and inclusion criteria were applied. Articles that presented pretreatment and posttreatment cephalometric values were preferred.

Influence of orthodontic treatment, midline position, buccal corridor and smile arc on smile attractiveness.

Objective: To assess the scientific evidence of the influence of some variables on smile attractiveness: orthodontic treatment, midline position, axial midline angulation, buccal corridor, and smile arc.

Materials And Methods: Literature was searched through PubMed, Web of Science, Embase, and All EBM Reviews. The inclusion criteria consisted of studies written in English; published in the past three decades; concerning the influence of orthodontic treatment, midline position, axial midline angulation, buccal corridor, and smile arc on smile esthetics; and judged by a minimum of 10 raters.
