Automated dentition segmentation: 3D UNet-based approach with MIScnn framework.

Introduction: Advancements in technology have led to the adoption of digital workflows in dentistry, which require the segmentation of regions of interest from cone-beam computed tomography (CBCT) scans. These segmentations assist in diagnosis, treatment planning, and research. However, manual segmentation is an expensive and labor-intensive process.

Genetic and environmental impact on mandibular growth in mono- and dizygotic twins during adolescence: A retrospective cohort study.

Introduction: This study aimed to discover the genetic and environmental factors that contribute to the mandibular development of untreated monozygotic and dizygotic twins.

Material And Methods: The sample, taken from the Forsyth Moorrees Twin Study, included 52 untreated monozygotic twins (36 male, 16 female) and 46 untreated dizygotic twins (23 male, 23 female). At the ages of 12 and 17, lateral cephalograms were collected and traced to assess total mandibular length, mandibular ramus length, mandibular corpus length, gonial angle, SNB, and bony chin prominence.

Multinational study on profile preference of laypersons.

Background: This study aimed to assess the facial profile preferences of lay people in seven locations from different countries and whether their place of residence, sex, age, race, education, or income influenced the decision.

Methods: After altering the lip and nose in 1 mm increments in the sagittal and sagittal/vertical directions, 50 profile silhouettes with white-like facial features were rated by evaluators. The soft tissue values were integrated into the profiles, and profile preferences were identified for each location.

Three-dimensional morphometric analysis of anterior cranial base in growing patients.

Introduction: The growth of the sphenoethmoidal and sphenofrontal suture in the anterior cranial base (ACB) terminates around 7 years old; therefore, ACB is used as a reference structure for superimposing radiographs in 2-dimensions (2D) and 3-dimensions (3D). The data in the literature regarding the cessation of growth of ACB in 3D is insufficient. The study aimed to evaluate the volumetric changes of ACB in growing patients on cone-beam computed tomography (CBCT) data in 3D.
