Calcium phosphate nanoparticles for potential application as enamel remineralising agent tested on hydroxyapatite discs

Abstract

Calcium phosphate nanoparticles (hydroxyapatite, 63.9 ± 15.9 nm, rod-shaped, Ca/P: 1.39, low crystallinity, calcium-deficient, carbonated) were shown to increase the surface microhardness and step height of eroded hydroxyapatite discs.

A Remineralizing and Antibacterial Coating for Arresting Caries

“…The antibacterial activity was evaluated with the plate count method as previously described (He et al 2019). Crystal violet (Beyotime) and the LIVE/DEAD BacLight Viability Kit (Life Technologies Corporation) were used to determine the anti-biofilm effect according to the recommended protocol (He et al 2019; Mok et al 2021). Details are provided in the Appendix.…”

Modification of the crystallographic parameters in a biomaterial employing a series of gamma radiation doses

“…The prepared sample was separated by utilizing a vacuum filtration apparatus and subsequently stored in a polyethylene bag maintaining an air seal. Eqn (1) shows the relevant reaction that occurred in the HAp synthesis.…”

“…There has been emerging interest in hydroxyapatite (HAp) due to its morphology, crystallinity, and chemical composition which are very similar to those of human hard tissue, 1 60–70% of which is composed of this biomaterial. 2 It is being widely used as a potential bone graft substitute material in orthopedic and dentistry fields, 3 and thus controlling its properties is very crucial for fruitful applications, notably 2.2 million people need bone grafting per year.…”

A multifunctional polymeric coating with self-adsorbed, antifouling and in situ remineralization properties for caries management

“…The acid-etching process changed the regular structure of the enamel surfaces and loosened the HA structure, 57 providing the enamel surfaces with countless tiny pores (Fig. S2, ESI †), which will be beneficial for the deposition of exogenous Ca and P. 58 As can be seen from Fig. 5A-D, the newly formed minerals of all groups treated with DIW, PEG-PAsp and PEG-PAsp-ALN increased with the immersing time going by, indicating that three groups of enamel samples had certain remineralization ability.…”
