Electric field promoted odontogenic differentiation of stem cells from apical papilla by remodelling cytoskeleton

International Endodontic Journal, EarlyView.
Abstract Aim This study examined the impact of direct current electric fields (DCEFs) on the biological properties of stem cells derived from the apical papilla (SCAP) and further elucidated the underlying mechanisms involved in odontogenic differentiation induced by DCEFs stimulation.

Orthodontic Wire Ingestion during Treatment: Reporting a Case and Review the Management of Foreign Body Ingestion or Aspiration (Emergencies)

Case Reports in Dentistry, 2013
Today orthodontic treatment is in growing demand and is not limited to a specific age or social group. The nature of orthodontic treatment is such that the orthodontic wires and appliances, which are used to apply force and move the teeth, are exposed to

Right wire in orthodontics: a review

Journal of Research in Dentistry, 2015
Quality of orthodontic wire such as stiffness, hardness, resiliency, elasticity and working range are important determinants of the effectivenes of tooth movement. Commonly used types of orthodontic arch wire:1) stainless steel(ss) wire, 2) conventional nickel- titanium (NiTi)alloy wire,3) improved super elastic NiTi- alloy wire( also called low ...

Automatic Recognition of Landmarks on Digital Dental Models [PDF]

arXiv, 2020
Fundamental to improving Dental and Orthodontic treatments is the ability to quantitatively assess and cross-compare their outcomes. Such assessments require calculating distances and angles from 3D coordinates of dental landmarks. The costly and repetitive task of hand-labelling dental models impedes studies requiring large sample size to penetrate ...

AI‐Driven Detection and Measurement of Keratinized Gingiva in Dental Photographs: Validation Using Reference Retainers

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To evaluate a deep learning (DL) model for detecting keratinized gingiva (KG) in dental photographs and validate its clinical applicability using reference retainers for calibration. Materials and Methods A total of 576 sextant photographs were selected from 32 subjects, each with three sets of photographs: iodine‐stained, unstained and ...

MECHANICAL ANALYSIS OF ORTHODONTIC WIRES

Diyala Journal of Engineering Sciences, 2012
Orthodontic tooth movement is a physiologic response to externally applied forces; the motive forces are primarily mechanical. The optimal application of orthodontic force enables maximum movement of teeth with minimal irreversible damage of the periodontal ligament (PDL), alveolar bone, and teeth.

Intraoral scanning for implant‐supported complete‐arch fixed dental prostheses (ISCFDPs): Four clinical reports

Journal of Prosthodontics, EarlyView.
Abstract Although there are difficulties with using intraoral scans for implant‐supported complete‐arch fixed dental prostheses (ISCFDPs), several commercially available systems have become helpful in simplifying the treatment process in the prosthetic phase.
