Bhubaneswar: Researchers have developed a bioactive peptide that coats tooth surfaces, helping prevent new cavities and heal existing ones in lab experiments.
The study has been published in the ACS Applied Materials & Interfaces. The researchers based their anti-cavity coating on a natural antimicrobial peptide called H5.
Produced by human salivary glands, H5 can absorb onto tooth enamel and destroy a broad range of bacteria and fungi.
To promote remineralisation, the team added a phosphoserine group to one end of H5, which they thought could help attract more calcium ions to repair the enamel than natural H5.
