Special Issue Information

Dear Colleagues,

In the early 1960s, Dr. Rafael Bowen of the American Dental Association pioneered the development of methacrylate-based resin composites. Over a decade later, dentists began utilizing these composites in the treatment of caries. Fast forward six decades from their inception, and methacrylate-based restoratives continue to maintain their dominance in the realm of dental adhesives and restorative composites. Their enduring popularity can be attributed to their natural tooth-like appearance, strong bonding capabilities with natural teeth, and versatility for use in both small and large restorations. This has propelled them into the limelight, surpassing alternatives such as amalgam and glass ionomer cements.

Modern dental composite restorative systems, in tandem with the associated adhesives for dentin and enamel, are typically composed of three essential components: 1) a resin network, 2) reinforcing filler particles, and 3) additives that supply unique functions. Dentists and scientists creatively blend these three components, akin to artists mixing RGB colors, to address a wide array of complex dental cases. With over half a century of clinical data and ongoing development, new materials and advanced technologies continue to emerge.

In this Special Issue, our objective is to provide a comprehensive review and witness the evolution of dental adhesives and resin composites. We will delve into the artistry involved in crafting functional dental restoratives, explore the excitement of applying cutting-edge materials and technologies, and take immense satisfaction in contributing to the overall well-being of humanity.

Root caries caused by cariogenic bacteria are a burden on a large number of individuals worldwide, especially the elderly. Applying a protective coating to exposed root surfaces has the potential to inhibit the development of caries, thus preserving natural teeth. This study aimed to develop a novel antibacterial coating to combat root caries and evaluate its effectiveness using the antibacterial monomer dimethylaminohexadecyl methacrylate (DMAHDM). DMAHDM was synthesized and incorporated into a resin consisting of 55.8% urethane dimethacrylate (UDMA) and 44.2% TEG-DVBE (UV) at a 10% mass fraction of glass filler. Multiple concentrations of DMAHDM were tested for their impact on the resin’s mechanical and physical properties. S. mutans biofilms grown on resin disks were analyzed for antibacterial efficacy. Cytotoxicity was assessed against human gingival fibroblasts (HGFs). The results showed an 8-log reduction in colony-forming units (CFUs) against S. mutans biofilm (mean ± sd; n = 6) (p < 0.05) when 5% DMAHDM was incorporated into the UV resin. There was a 90% reduction in metabolic activity and lactic acid production. A low level of cytotoxicity against HGF was observed without compromising the physical and mechanical properties of the resin. This coating material demonstrated promising physical properties, potent antibacterial effects, and low toxicity, suggesting its potential to protect exposed roots from caries in various dental procedures and among elderly individuals with gingival recession.

This review article will discuss the origin of resin-based dental composite materials and their adoption as potentially useful adjuncts to the primary material used by most dentists for direct restorations. The evolution of the materials, largely driven by the industry’s response to the needs of dentists, has produced materials that are esthetic, strong, and versatile enough to be used in most areas of the oral cavity to replace or restore missing tooth structures. Significant advancements, such as the transition from chemical to light-curing materials, refinements in reinforcing particles to produce optimum polishing and wear resistance, formulating pastes with altered viscosities to create highly flowable and highly stiff materials, and creating materials with enhanced depth of cure to facilitate placement, will be highlighted. Future advancements will likely reflect the movement away from simply being a biocompatible material to one that is designed to produce some type of beneficial effect upon interaction within the oral environment. These new materials have been called “bioactive” by virtue of their potential effects on bacterial biofilms and their ability to promote mineralization of adjacent tooth structures. Full article
