The Myths and Realities of Bioactivity

The Roundtable video series is a forum for discussion and debate on key topics, trends, and techniques in dentistry. For each edition, Inside Dentistry's editor-in-chief, Robert C. Margeas, DDS, and a panel of experts examine a subject to help expand your knowledge and improve your practice. This month, our panel takes a look at one of the most ubiquitous buzzwords in clinical dentistry, "bioactivity."

As the discussion begins, the panel explores what constitutes a bioactive material. Thomas E. Dudney, DMD, notes that years ago, there was a lot of confusion surrounding the word bioactive, but now, it has become a term that is used more frequently in dentistry, so more people are starting to understand it. Chad C. Duplantis, DDS, agrees and defines a bioactive material as "a material that has a positive biologic effect on the surrounding tissues." He asserts that all dentists should be looking to incorporate bioactive materials into their practices because dentists are oral physicians, not tooth mechanics, and they need to start looking at the things that provide benefit to the patient's oral cavity and body.

The conversation then turns to research. There have been independent studies on bioactive composites that demonstrate successful long-term results in terms of retention rates and the absence of secondary caries, failures, and postoperative sensitivity. Fay Goldstep, DDS, says that research very much influences her decisions when she is choosing restoratives, but it isn't the only thing that she takes into account. "I like the research, but the most important thing is the handling properties and the way the materials perform inside my practice. So, you get the clinical results from the studies, and then you form your own opinions."

The panel members agree that the bioactive restoratives that are on the market now can be just as esthetic as those marketed as "esthetic," while offering the added bonus of bioactivity. To conclude, they share what they believe is on the horizon for the future of bioactive materials.
