Dental CLAIRES: Contrastive LAnguage Image REtrieval Search for Dental Research [PDF]

AMIA 2023 Informatics Summit, 2023
Learning about diagnostic features and related clinical information from dental radiographs is important for dental research. However, the lack of expert-annotated data and convenient search tools poses challenges. Our primary objective is to design a search tool that uses a user's query for oral-related research.

Ontogeny reveals function and evolution of the hadrosaurid dinosaur dental battery [PDF]

, 2016
BACKGROUND: Hadrosaurid dinosaurs, dominant Late Cretaceous herbivores, possessed complex dental batteries with up to 300 teeth in each jaw ramus. Despite extensive interest in the adaptive significance of the dental battery, surprisingly little is known

Bi‐Layered Biphasic Calcium Phosphate Bone Substitute to Improve Bone Formation in Lateral Jaw Defects Applying the Principle of Guided Bone Regeneration (GBR)—A Pre‐Clinical Randomized Controlled Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Aim To evaluate the application of a synthetic bi‐layered biphasic calcium‐phosphate (BBCP) bone substitute for its capacity for new bone formation in Guided Bone Regeneration (GBR) in an acute‐defect model in Beagle dogs. Material and Methods Standardized bone defects were created following the extraction of the maxillary 1P1, 2P2, 4P4 and ...

Trace element distribution in human teeth by x-ray fluorescence spectrometry and multivariate statistical analysis [PDF]

arXiv, 2014
X-ray fluorescence spectrometry (XRFS) was used as a multielement method of evaluation of individual whole human tooth or tooth tissues for their amounts of trace elements. Measurements were carried out on human enamel, dentine, and dental cementum, and some differences in tooth matrix composition were noted.

Forensic determination of dental age by cementum thickness of human teeth.

The Journal of forensic odonto-stomatology, 2021
The purpose of this study was to assess the correlation between the known chronological age and the dental cementum thickness (DCT) in male and female subjects in different age groups.The study sample consisted of 57 donor teeth of both sexes. Teeth were classified by donors' sex and divided into three age groups: 10-19, 30-39 and 60-69 years.

Sirt3 Rescues Porphyromonas gingivalis‐Impaired Cementogenesis via SOD2 Deacetylation

Cell Proliferation, EarlyView.
Sirt3 deacetylated SOD2 via K68 to orchestrate P.g.‐impaired cementogenesis. Reestablishment of the Sirt3/SOD2 axis by honokiol reduced SOD2 acetylation and facilitated cementogenesis. ABSTRACT The keystone pathogen Porphyromonas gingivalis (P.g.) is responsible for cementum resorption in periodontitis; however, the mechanism involved in it remains ...
