Iranian Researchers Produce Biocompatible Anti-Bacterial Dental Resins
TEHRAN (FNA)- Iranian scientists at Islamic Azad University’s Tehran branch developed a new type of dental material based on the bioactive extract of thyme called thymol, which, in addition to having antibacterial properties, is biocompatible.

The purpose of this project was to provide antibacterial dental resins based on thymol and the cost-effective bioactive material, induction of antibacterial properties in dental resins without loss of physical-mechanical properties and maintaining color stability of dental resins in the presence of thymol.

Due to its structural nature and hydrophobic nature, thymol has good solubility in dental resins, and adding it to dental materials does not increase the water absorption of the samples, and as a result, the physical-chemical properties of dental materials in the wet environment of the mouth are not affected.

In a relevant development last month, Iranian scientists at Tehran University succeeded in the production of a new type of dental implants by production of a strong alloy using nanotechnology.

“At present, these types of implants are made of titanium alloy containing vanadium metal and aluminium which are harmful,” Qader Faraji, the executor of the plan, said.

He added that they have applied advanced technology of ‘severe plastic deformation’ to produce the new implants.

“The new product has a nano structure and the toxic metals have been filtered out but the product is as strong as the titanium alloy containing vanadium metal and aluminium. The product is now in the state of commercialization,” Faraji said.

Iran is a leading nation in nanotechnology. Only in 2018, Iranian researchers published 9,662 papers and articles in the field of nanotechnology, bringing the country among the top 4 in the world in this area of technology.
