Effect of tea root-derived proanthocyanidin fractions on protection of dentin collagen
Journal of International Medical Research, 2020 Objectives Proanthocyanidins (PAs) have been widely used as effective agents for dentin collagen cross-linking to enhance the biomechanics and biostability of dentin in vitro.

Measure of the hygroscopic expansion of human dentin [PDF]
arXiv, 2022 Background: Direct dental restoration implies a drying of the dentin substrate. This drying may induce significant strain in the dentin, affecting the bonding efficiency of the restoration. Objective: We measure the dilatation of dentine under changes of relative humidity as well as the impact of humidity on dentin elastic properties. This investigates

Ecological Hypothesis of Dentin and Root Caries
Caries Research, 2016 Recent advances regarding the caries process indicate that ecological phenomena induced by bacterial acid production tilt the de- and remineralization balance of the dental hard tissues towards demineralization through bacterial acid-induced adaptation ...

Hereditary dentine disorders: dentinogenesis imperfecta and dentine dysplasia [PDF]
Orphanet Journal of Rare Diseases, 2008 Abstract The hereditary dentine disorders, dentinogenesis imperfecta (DGI) and dentine dysplasia (DD), comprise a group of autosomal dominant genetic conditions characterised by abnormal dentine structure affecting either the primary or both the primary and secondary dentitions. DGI is reported to have an incidence of 1 in 6,000 to 1 in 8,000,

Effect of glazing and polishing on opalescence and fluorescence of dental ceramics
Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1645-1654, December 2022., 2022 Abstract Objective Tooth enamel has opalescence and fluorescence, which should be mimicked by esthetic dental restorations. The purpose of this study was to compare the effects of glazing and polishing on the opalescence and fluorescence of dental ceramics. Materials and Methods Twenty‐four discs were fabricated of feldspathic, IPS e.max, zirconia, and

Comparison of the microstructure of crown and root dentin by a scanning electron microscopic study
Journal of Dental Sciences, 2010 Detailed information of the dentin microstructure is essential in order to interpret data from investigations on dentin adhesive materials. Most studies of dentin microstructure focused on the crown dentin, and few compared microstructures of the crown ...

The dynamics of TGF-β in dental pulp, odontoblasts and dentin
Scientific Reports, 2018 Transforming growth factor-beta (TGF-β) is critical for cell proliferation and differentiation in dental pulp. Here, we show the dynamic mechanisms of TGF-β in porcine dental pulp, odontoblasts and dentin.

Antibacterial effects of natural compounds on biofilm formation of Streptococcus mutans
Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1426-1433, December 2022., 2022 Abstract Streptococcus mutans is the main cariogenic pathogen in the oral cavity, considered to contribute toward oral diseases. S. mutans is predominantly entrapped in plaque biofilms. Objectives In this study, we surveyed the antibacterial activity of natural compounds in terms of the biofilm production of S. mutans. Material and Methods We extracted
