Ideal mentolabial sulcus depth in long-face, short-face, and normal-face in female individuals.

Purpose: The harmony between the lips and the chin is an essential parameter in facial esthetics, and the mentolabial sulcus (MLS) represents the level of this harmony. This study aimed to assess the effect of MLS depth on facial profile attractiveness in long-face, short-face, and normal-face Iranian female individuals.

Methods: An observational study with a questionnaire was conducted, and a profile photograph of an Iranian female with class I occlusion was altered to create long-face, normal-face and short-face profiles with MLS depth ranging from 1 to 12 mm.

Effects of facial forms and midline deviations and rolls on female facial beauty according to laypeople, orthodontists, and prosthodontists or restorative dentists.

No study has examined the simultaneous effect of facial forms, midline deviations and midline angulations on facial beauty. Therefore, this comprehensive study aimed to evaluate these and many other hypotheses. This psychometric study was performed on 15,042 observations.

Evaluation of alkaline phosphatase in gingival crevicular fluid and saliva of patients with periodontitis and healthy individuals.

Introduction: In recent decades, biomarkers have been used to predict the progression of chronic periodontitis. One of these biomarkers is alkaline phosphatase (ALP). Due to limitations of the performed studies, this study was performed to determine the amount of salivary ALP and gingival crevicular fluid in patients with chronic periodontitis and healthy individuals.

Psychometric and Perceptometric Comparisons of the Perspectives of Orthodontists, Oral and Maxillofacial Surgeons, and Laypeople of Different Ages and Sexes towards Beauty of Female Jaw Angles (Intergonial Widths and Gonial Heights) on Frontal and Three-Quarter Views.

Objectives: The jaw angle plays an important role in facial beauty. Therefore, this study is aimed at comparatively determining the range of most attractive female intergonial widths and gonial heights on Perceptometric frontal-view and three-quarter-view images, from the perspective of orthodontists, oral maxillofacial (OMF) surgeons, and laypeople of different ages and sexes.

Methods: This prospective multivariate Perceptometric study was performed on 4191 esthetic scores given by 127 individuals to 33 Perceptometric face images.

Cell homing strategy as a promising approach to the vitality of pulp-dentin complexes in endodontic therapy: focus on potential biomaterials.

Introduction: Over the last two decades, an increasing body of research suggests that well-designed biomaterials can attract resident stem cells to injured areas and control their behaviors and activities to encourage tissue regeneration. Fabricated biomaterials can enhance cell recruitment, multiplication, and transformation while also acting as a delivery system for targeted cells. These capabilities might play a role in their ability to promote tooth regeneration.

Dynamics, Efficacies, and Adverse Effects of Maxillary Full-Arch Intrusion Using Temporary Anchorage Devices (Miniscrews): A Finite Element Analysis.

Introduction: Absolute anchorages obtained from temporary anchorage devices (TADs, miniscrews) considerably facilitate dental movements and make some very difficult movements such as full-arch intrusions possible. Despite the significance of assessing strategies to fully intrude the arch using mini-implants, there is no study in this regard except a few case reports. Therefore, we simulated/tested 4 scenarios.
