Comparison of self-perception in relation to the normative need for orthodontic treatment in a population of dental students in Brazil: A cross-sectional study.

Introduction: This study aimed to identify predictive factors of having a positive or negatively divergent self-perception from the normative orthodontic treatment need (N-OTN).

Methods: All eligible undergraduate students from the School of Dentistry of the XXX were recruited through convenience sampling. They were clinically evaluated to determine their N-OTN using the IOTN and were asked about their self-perceived orthodontic treatment need (S-OTN) using the same scale for both evaluations.

A clinical approach to managing open-bite malocclusion associated with severe crowding.

Open bite has been identified as one of the most challenging malocclusions in orthodontics. The treatment approach is complex, the resulting esthetics may not meet the patient's expectations, and the chance of recurrence is high. A 13-year-old girl presented a skeletal Class II malocclusion associated with anterior and posterior open bite, maxillary transverse deficiency, severe anterior crowding, and a hyperdivergent facial pattern.

The influence of cigarette smoke on colour stability and friction property of aesthetic orthodontic wires-In vitro study.

Objective: To evaluate the colour stability and friction property of aesthetic orthodontic wires when exposed to cigarette smoke.

Materials And Methods: Forty-eight samples of aesthetic orthodontic wires (0.019″×0.

Evaluation of facial soft tissue thickness in symmetric and asymmetric subjects with the use of cone-beam computed tomography.

Introduction: The aims of this study were to evaluate facial bilateral soft tissue thickness in symmetric and asymmetric subjects and to investigate whether soft tissue compensates for skeletal asymmetry.

Methods: Cone-beam computed tomography (CBCT) scans of 97 subjects were divided into a symmetry group (GSm) and an asymmetry group (GASm). Seven bilateral points were established.
