A Cross-Sectional Study Examining Andrews' Analysis in Caucasian and African American Subjects.

Background: Andrews' analysis is a commonly utilized instrument to aid in esthetic positioning of the anteroposterior position of the maxillomandibular complex; however, there is limited data regarding use in non-Caucasian subjects.

Purpose: The purpose of this study was to document laypersons preferences of anteroposterior position of the maxillomandibular complex in relation to Andrews' lateral profile analysis in African American (AA) and Caucasian subjects.

Study Design, Setting, Sample: A cross-sectional study was implemented to evaluate the esthetics of AA and Caucasian subjects.

The Impact of Orthodontic Retainers on Gingival Recession: A Best-Evidence Review.

Retention is a critical phase of orthodontic therapy and aims to maintain occlusal stability and avoid crowding relapse. This best-evidence article reviews the effects of the different types of orthodontic retention appliances, fixed and removable, on the development and progression of gingival recession at the mandibular anterior teeth. Searched databases included PubMed, Scopus, Cochrane Library, Embase, and Dentistry and Oral Sciences.

The new periodontal disease classification: Level of agreement on diagnoses and treatment planning at various dental education levels.

Purpose/objectives: Using the periodontal diseases classification published in 2018, this study evaluated the level of agreement among predoctoral and postgraduate students of different education levels and specialties in the diagnosis and treatment planning of periodontal conditions.

Methods: Second-year (D2) and fourth-year (D4) dental students, postgraduate orthodontic students (OS), and periodontology students (PS) were presented with an anonymous survey of 10 cases, each with five choices of diagnosis and seven therapeutic approaches. The cases included a patient summary, photographs, radiographs, periodontal charting, and ranged from health to periodontitis.

Evaluation of preferred lip position according to different tip rotations of the nose in class I young adult subjects.

Introduction: The mouth plays an important role in the overall aesthetic appearance of the face. The aims of this study were to determine the optimal antero-posterior (AP) lip position relative to various rotations of the nasal tip and assess the impact of the nasolabial angle on facial aesthetics.

Material And Methods: Three-dimensional facial volumes, in motion, of one Caucasian male and one Caucasian female with a Class I malocclusion and an orthognathic profile were modified to alter the nasal tip rotation (3 rotations) and the AP lips position (6 positions).
