Effect of S-PRG particles on demineralization and remineralization of dentin: a clinical case report

Abstract

It is known that the production of acid by oral bacteria dissolves mineral phases on the enamel surface, facilitating the formation of dental caries, with lactic acid being the main cause of caries, followed by acetic and propionic acids. Fluoride-containing materials play an important role in preventing demineralization and remineralization and these are widely used in dentistry. Although the benefits of fluoride in terms of reducing the incidence of dental caries are well established, fluoride cannot prevent caries in all patients; thus, the development of new anti-caries agents with remineralization properties is necessary. Thus, new products are emerging with this purpose and in this article, a material with Surface Pre Reacted Glass ionomer (S-PRG) particles will be addressed, these are produced by the acid-base reaction of fluoroboroaluminosilicate glass and polyacrylic acid and are known to have a potential to release 06 ions, such as Al, B, Na, Si, Sr and F, where these released ions played an important role in pH neutralization, leading to inhibition of enamel demineralization early point, where strontium (Sr) is becoming as a strong inducer of dentin matrix remineralization. Thus, this work aimed to demonstrate with a clinical case using S-PRG materials that can become an ally in the remineralization of the dental element. In conclusion, among the innovations that promote the concept of preventive and minimally invasive management, the bioactivity containing S-PRG can avoid invasive and definitive procedures such as tooth extraction.
