Production of antibacterial dental resins from thyme extract
Researchers at the Azad University have prepared dental materials using thyme extract, which in addition to having antibacterial properties, also has good biocompatibility and its use reduces tooth decay.
The research project of antibacterial dental resins was implemented by researchers of Islamic Azad University, Tehran Branch and with the support of the Fund for Support of Researchers and Technologists.
Preparation of antibacterial dental resins based on the plant bioactive substance thymol and cost-effective, induction of antibacterial properties in dental resins without loss of physical-mechanical properties and maintaining the color stability of dental resins in the presence of thymol and their discoloration.
The growth and activity of bacteria at the site of cracks created at the border of restorative materials and teeth, as well as cracks in the mass of dental material is the main cause of secondary caries.
Secondary caries has no symptoms to be identified in the early stages and usually progresses without any apparent symptoms. As a result, secondary caries are often diagnosed when they have progressed a lot and require composite replacement and recurrence.
Therefore, the use of dental materials with antibacterial properties is one of the most practical methods to prevent the growth and proliferation of bacteria on the tooth surface.
Since the type and structure of antibacterial material is of special importance in the preparation of antibacterial dental materials, in this project, a new type of dental material based on the bioactive extract of Thyme plant called thymol was prepared, which has desirable properties such as Significant antibacterial properties and biocompatibility, good solubility in dental methacrylate resins for the preparation of dental resins, have desirable physical-mechanical properties and low water absorption.
According to the information center of the scientific vice chancellor, in addition to inducing strong antioxidant and antibacterial properties, thymol has a good biocompatibility.
In addition, due to its structural nature and hydrophobic nature, thymol has good solubility in dental resins and its addition to dental materials does not increase the water absorption of samples and thus affects the physicochemical properties of dental materials in wet oral environment. They do not take.
