Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Efficient induction of functional ameloblasts from human keratinocyte stem cells

Stem Cell Research & Therapy, 2018
Background Although adult human tissue-derived epidermal stem cells are capable of differentiating into enamel-secreting ameloblasts and forming teeth with regenerated enamel when recombined with mouse dental mesenchyme that possesses odontogenic ...

Coeliac-type Permanent-tooth Enamel Defects

Annals of Medicine, 1996
Systematic and chronologically distributed permanent-tooth so-called coeliac-type enamel defects are highly prevalent both in children and adults with coeliac disease (gluten-sensitive enteropathy) and dermatitis herpetiformis. Coeliac-type enamel defects were also found in healthy first-degree family members of coeliac disease patients.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

Cdc42 deletion yielded enamel defects by disrupting mitochondria and producing reactive oxygen species in dental epithelium

Genes and Diseases
Developmental defects of enamel are common due to genetic and environmental factors before and after birth. Cdc42, a Rho family small GTPase, regulates prenatal tooth development in mice.

Does chewing xylitol gum improve oral health? [PDF]

, 2013
Popular chewing gum brands such as Orbit and Trident advertise that chewing their gum promotes oral health due to the presence of xylitol. This compound has interested oral health researchers since the 1970 s, but recent advances in research have been ...

The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

The Anatomical Record, EarlyView.
Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

The crucial role of centrioles in tooth growth and development

Journal of the Formosan Medical Association
Background: Tooth development hinged on reciprocal interactions between enamel and dentin, shaping tooth structures. Centrioles influenced cellular direction, critical for stem cell differentiation.

Crystallographic and Colorimetric Analysis of Dental Enamel

Dental Anthropology, 1997
Tooth color and the correlation of the composition of dental enamel with color were investigated in samples of teeth from two medieval Serb cemeteries. Differences in the composition of apatite crystals in the dental enamel of the two samples were found.
