Liners, bases and varnishes

One of the most controversial areas of restorative dentistry is the subject of liners, varnishes and bases. Currently, there is no single protocol, with respect to the use of liners, varnishes and bases, for clinicians to follow. This article is an in-depth literature review that discusses the use of liners, varnishes and bases and the types of materials that are available to the restorative dentist. The new emerging concept of minimally invasive dentistry will require new restorative techniques. These changes will require the clinician to revaluate their use of liners, varnishes and bases. Other clinical considerations and findings from recent research are discussed.
