Advances in Dental Cementation

Thomas E. Dudney, DMD; Jack D. Griffin Jr, DMD; and Gregg Helvey, DDS, CDT

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 discusses cementation materials and techniques. To watch the whole conversation, go to:

According to panelist Jack D. Griffin Jr, DMD, lithium disilicate and zirconia are the frontrunners in restorative materials because of their esthetic qualities, straightforward preparations, and affordability.

Although the panel agrees that certain clinical situations call for these materials to be adhesively bonded, cementation is generally the preferred technique "because it's simpler and easier," says Thomas E. Dudney, DMD. In addition, careful material-driven preparations are paramount in order to achieve successful results.

Our experts also touch on the emergence of bioactive cements and how they're changing restorative dentistry. "These materials provide ions that stimulate dentin repair and remineralization, and they have the potential to be kind to the surrounding tissues," says Griffin.

Secondary decay in restorations is one of the biggest problems that today's dentists face, notes Gregg Helvey, DDS, CDT, and bioactive cements are an available solution. "They can grow hydroxyapatite into the microgaps where bacteria would normally infiltrate," he explains. "Bioactivity is something that I hope research will continue to focus on as a newer approach to cementing." The discussion concludes with some troubleshooting tips for restoring with modern cements.
