Resin based restorative dental materials: characteristics and future perspectives

Abstract

This review article compiles the characteristics of resin based dental composites and an effort is made to point out their future perspectives. Recent research studies along with few earlier articles were studied to compile the synthesis schemes of commonly used monomers, their characteristics in terms of their physical, mechanical and polymerization process with selectivity towards the input parameters of polymerization process. This review covers surface modification processes of various filler particles using silanes, wear behaviour, antimicrobial behaviour along with its testing procedures to develop the fundamental knowledge of various characteristics of resin based composites. In the end of this review, possible areas of further interests are pointed out on the basis of literature review on resin based dental materials.

Rapid Fabrication of Sterile Medical Nasopharyngeal Swabs by Stereolithography for Widespread Testing in a Pandemic

“…[ 36,37 ] Dental resins are generally based off vinyl, polystyrene, or acrylic resins to be used as relining, die, impression, crown, and with other oral care applications. [ 38 ] Although biocompatibility resists precise definition in areas like tissue engineering, [ 39 ] in dentistry, an extended history of biocompatibility tests and protocols have been designed for local (mucosal and pulpal toxicity) and systemic (allergic, estrogenic, mutagenicity, and more) adverse reactions in vitro, in animals, in clinical studies, as well as occupational cyclic exposure. [ 40–44 ] One notable biocompatible acute toxicity assessment test is performed on fish embryos, where their stages of development are observed for chemical effects from exposure to the material over time.…”

Effect of Different Polishing Systems on the Surface Roughness and Gloss of Novel Nanohybrid Resin Composites

“…The final surface polish of resin composite restorations could be affected by many variables, such as resin composite type, resin monomer type, the load of filler particles, as well as finishing/polishing (F/P) system used. 10,11 When different techniques are proposed, not only their efficiency in maintaining a smooth surface but also their ability to obtain a gloss surface have to be considered. 12 This study aims to evaluate the effect of three F/P systems on the surface roughness and gloss of three nanohybrid resin composites and one microhybrid resin composite.…”

Validation of a Simple HPLC–UV Method for the Determination of Monomers Released from Dental Resin Composites in Artificial Saliva

“…However, BPA can be found as an impurity or as a degradation product from the hydroxylation of Bis-GMA [24]. Bis-GMA is the most widely used monomer in dental resin materials, and its high viscosity is responsible for the reduced degree of conversion of the monomers, which leads to its higher elution in the human body [25].…”

“…UDMA is less cytotoxic and has a higher polymerization rate and degree of conversion than other monomers. Nevertheless, it can cause damage to ovary cell DNA, and, in some cases, induct apoptosis [5,25].…”
