Dentine sialophosphoprotein signal in dentineogenesis and dentine regeneration [PDF]
European Cells and Materials, 2021 Dentineogenesis starts on odontoblasts, which synthesise and secrete non-collagenous proteins (NCPs) and collagen. When dentine is injured, dental pulp progenitors/mesenchymal stem cells (MSCs) can migrate to the injured area, differentiate into odontoblasts and facilitate formation of reactionary dentine.

Sex bias in Neolithic megalithic burials
American Journal of Biological Anthropology, Volume 180, Issue 1, Page 196-206, January 2023., 2023 Abstract Objectives A statistical study comparing osteological and ancient DNA determinations of sex was conducted in order to investigate whether there are sex biases in United Kingdom and Irish Neolithic megalithic burials. Materials and Methods Genetic and osteological information from human individuals from 32 megalithic sites in the UK and Ireland

Elemental models of primate nursing and weaning revisited
American Journal of Biological Anthropology, Volume 180, Issue 1, Page 216-223, January 2023., 2023 Abstract Objectives Intra‐tooth patterns of trace elements barium (Ba) and strontium (Sr) have been used to infer human and nonhuman primate nursing histories, including australopithecine and Neanderthal juveniles. Here, we contrast the two elemental models in first molars (M1s) of four wild baboons and explore the assumptions that underlie each ...

Dentin degradomics in dentin erosion
STOMATOLOGY EDU JOURNAL, 2022 Background Dentin degradomics are the enzymes found in dentin endogenously and are aimed at attacking organic compounds of the relevant tissue. During dentin demineralization, these enzymes could turn into the reaction phase and may step up the degradation. Thus, their connection with dentin erosion and tissue loss should be explained.

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1533-1539, December 2022., 2022 Abstract Background The main purpose of this experimental study was to determine the in vitro effects of two calcium phosphate‐containing agents (Remin Pro® and GC Tooth mousse™) on the enamel resistance of permanent molars to demineralization. Methods Fifty extracted human third molars were randomly divided into four groups; that is the control group ...

Dentin sialoprotein and dentin phosphoprotein have distinct roles in dentin mineralization [PDF]
Matrix Biology, 2009 Dentin sialophosphoprotein (DSPP), a major non-collagenous matrix protein of odontoblasts, is proteolytically cleaved into dentin sialoprotein (DSP) and dentin phosphoprotein (DPP). Our previous studies revealed that DSPP null mice display a phenotype similar to human autosomal dominant dentinogenesis imperfecta, in which teeth have widened predentin ...

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1575-1581, December 2022., 2022 Abstract Objective Effective bond strength of composite resin restoration leads to its durability, so evaluation of dentin surface treatment with enzymes and laser for higher bond strength is an important factor. Materials and Methods Sixty human molar teeth were cut at a depth of 2 mm of occlusal part and divided into six groups (n = 10).

Dentin Sialophosphoprotein (DSPP) and Dentin [PDF]
Journal of Oral Biosciences, 2008 The revolution in genetics disclosed the types of malformations that occur when expression of a particular gene is lost. In the case of tooth dentin, mutations in the two genes encoding type I collagen cause osteogenesis imperfecta, a bone condition that often includes dentin malformations.

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1582-1590, December 2022., 2022 Abstract Introduction The effectiveness of root canal therapy in endodontic practice is largely determined by providing a compact fluid‐tight closure at the apex of the root canal, which inhibits irritant entry and buildup, which leads to a biological breakdown of the attachment mechanism and failure.
