DIRECT BONDING: THE LATEST EVIDENCE
Over the past two decades dentistry has made important progresses, thanks to advancements in material science, technology and clinical techniques. Dental bonding revolutionized the shape and content of clinical dentistry, presenting a strong and minimally invasive alternative to the traditional materials. Early research in adhesive dentistry was much focused on the bond strength of composite resin to tooth, despite the fact that “sealing” is considered more of a critical issue than “retention” of composite restorations. Polymerization shrinkage of contemporary dental composites still threatens the success of all kinds of adhesive restorations, and is perhaps underestimated from simplified bonding tests. We present a systematic approach for simulation of clinical situation in laboratory research, where the bonded restoration is subject to challenges such as shrinkage stress and fatigue loading. In addition, by real-time imaging using Sadr’s OCT imaging and analytical methodologies, we demonstrate that the integrity of a composite restoration can be visually evaluated and monitored. The visual observations lead to recommendations on clinical procedures for bonding and material selection, leading to a key conclusion; the success of restoring teeth with adhesive technology requires not only an optimal bonding approach, but also a strategy to mitigate the stresses and biomechanically protect the bonded interface and the dental tissue. In this presentation, we will also briefly introduce the latest understanding of Silver Diamine Fluoride, as a new modality to fight against hard-to-treat caries lesions.
