Tooth decay or caries keeps on moving as the most widespread infectious disease all around the world. In this disease, the hard tissues of the tooth begin to loss because of the inflammation and necrosis of the underlying pulp. Only in the U.S., more than 20 million dental restorations are done every year that have a failure rate of more than 60%. And therefore, it is significantly required to develop some new therapeutics to recover the original form and function of the damaged dentin-pulp. If compared with other fields of recovery medicines, the progress in this connection is somewhat slow.
Tissue-development procedures that lead to taking off the normal extra-cellular matrix have used non-synthetic and synthetic braces to guide cell separation and in the case of bone matrix mineralization. Synthetic peptide hydrogels are considered v=quite promising in the new advancement of delivery systems. The short peptides are designed to assemble into nanofibers that capture living cell and produce macroscopic gels. These materials are non-inflammatory and non-toxic because of the single amino acids serve as building blocks. Now the modular concept has become quite versatile and highly controllable as well.
A team of researchers from Baylor College of Dentistry, Dallas; Rice University, Houston and the University of Regensburg Germany presented the results of studies on hydrogels peptides developed with amphiphiles in the 86th General Session of the International Association for Dental Research. They told that a short peptide sequence offers a driving force for self-assembly and it is attached with fatty acid. However, a different design concept has also been presented by them in which the self-assembling of peptide chains is obtained without joining a hydrophobic tail. Under this new design, the chains have the ability to add bioactive peptide sequences for cell union.
