Precision and security in restorative dentistry: the synergy of isolation and magnification.

It is often presumed that, since its introduction in 1864, the use of rubber dam in multiple dental procedures has increased. However, its use is not as widespread as one might expect. There still seem to be many obstacles that prevent clinicians from adopting it as a standard of care. Furthermore, it appears very difficult to scientifically prove the impact of its use on the final outcome of a given procedure. The fundamental idea of isolating the operatory field and preventing contamination is simple; the practical execution of it is more demanding. In this article, the authors not only focus on the essential criteria for predictable isolation, they also present an isolation strategy that can be translated into a step-by-step procedure. It is suggested that by adopting this strategy, clinicians can eliminate the most commonly experienced obstacles and optimize the full potential of isolation, even in extremely difficult clinical situations.
