Tribological behavior of dental resin composites: A comprehensive review

In order to meet consumer demand for highly functional and adaptable oral care products, tribology-related technical issues in dentistry must be resolved. Dental tribology literature is fragmented, and clinical and laboratory testing procedures for assessing tooth wear and damage are inconclusive. Therefore, there is a lack of a comprehensive scientific understanding of tooth wear, making it challenging to create effective mitigation techniques. The study of wear analysis for dental resin composites (DRCs) has not received much attention. Only the study of physical, mechanical, chemical, biological, thermal, and dynamic mechanical analysis was investigated. Therefore, the current review is based on the wear/tribology analysis of the DRCs. This review article includes the effect of different commercial dental composites and control factors on the wear property of DRCs. It also demonstrates the various type of medium used in tribological investigation of DRCs. Wear was conducted on the different wear simulators. Each wear simulator was operated by different control factors. Taguchi and analysis of variance (ANOVA) were also employed for the wear analysis. A scanning electron microscope (SEM) was used to surface morphology analysis of the dental composites. Filler content and its size has a significant role in the wear of dental composites.
