The Revolution of Remineralizing Biomaterials in Dentistry
The main challenge facing dental research is finding minimally invasive solutions that promote tooth preservation. New findings based on remineralizing biomaterials reveal that they are capable of reducing the degradation of dentin caused by tooth decay.
1. How Tooth Decay Affects Dentin and Collagen Fibers
The acid produced by bacteria when tooth decay occurs has the ability to demineralize dentin. This degrades the collagen fibers and initiates the deterioration of the teeth. Recent discoveries have demonstrated the effectiveness of remineralizing biomaterials in this situation.
Remineralizing biomaterials consist of bioactive glass. In the studies conducted, experimental resins based on this material were used. On the one hand, Bioglass 45S5 microparticles were used, and on the other, glass enriched with phosphates and fluoride.
Their effectiveness was tested by applying both materials to completely demineralized dentin. After being immersed in artificial saliva, an immunohistochemical analysis was performed. Through this analysis, the action of proteolytic enzymes and the subsequent deterioration of the dentin could be observed.
In turn, infrared spectroscopy was used on the samples in which the remineralizing biomaterials were applied. This technique was used to evaluate the remineralization induced by the experimental resins.
2. Findings from the Use of Remineralizing Biomaterials
After examining the samples, it was concluded that the remineralizing biomaterials containing fluoride and phosphates were the most effective. It is the fluoride and phosphate ions that succeed in slowing the degradation of collagen and dentin fibers.
These findings open up a new avenue of research for treating dental caries. Thanks to the use of remineralizing biomaterials, it would be possible to preserve tooth tissue and reduce the damage caused by caries.
These minimally invasive treatments reduce the amount of dentin tissue that needs to be removed. At the same time, the preserved tissues are remineralized using bioactive composites. An example of these remineralizing biomaterials is halloysite.
The studies were published in the Journal of Dental Research, a prestigious journal of scientific research.
