"Bioactive Dental Materials... What's up with that?" 

 head_ferracane

Jack L. Ferracane, PhD
Professor and Chair, Department of Restorative Dentistry, OHSU School of Dentistry

Synopsis: The word “bioactive” is becoming widespread to describe materials used in various aspects of oral healthcare. The definition of “bioactive” is a subject of debate, with some arguing that materials should have a direct effect on a biological system, as opposed to toxic or chemical effect. This presentation will describe the different views of “bioactivity” and provide examples of how this interesting and important concept is being pursued in dentistry. 

Learning Objectives: 
1. Describe the different interpretations of what “bioactivity” means for dental biomaterials.
2. Explain the mechanism of action of materials that claim “bioactivity” for the purpose of in situ mineral formation.
3. Explain the mechanism of action of materials that claim “bioactivity” for the purpose of affecting microorganisms to inhibit caries or mitigate inflammatory processes.
4. Identify a useful working definition for “bioactivity” as it relates to dental biomaterials.

Ana Bedran-Russo, DDS, MS, PhD 
Professor and Chair, Department of General Dental Sciences in Restorative Dentistry, Marquette University School of Dentistry 

Synopsis: The use of dental adhesive systems is essential to restorative dentistry and is often seen as a quick step during placement of direct and indirect restorations. However, this routine step is key for the longevity of dental restorations. Here we will provide an overview of the status of dental adhesive systems, clinical shortcomings, and tips to improve performance. The presentation will also cover future trends. 

Learning objectives: 
1. Review and differentiate types of dental adhesive systems for bonding to enamel and dentin
2. Learn about current pitfalls with adhesive-based restorations leading to secondary caries
3. Develop an understanding of technological advancements of bonding systems and limitations
4. Learn strategies to improve sealing and strength of adhesive-based restorations.

Dr. Bedran-Russo utilizes her experience as dentist and biomaterials researcher to understand functional aspects of dental tissues towards the goal of strengthening and sustaining the natural dentition. Her clinical efforts center on preserving tooth structure and minimally invasive interventions and include leading clinical trials. Her research lab is focused on studies of dentin and its relationship with dental biomaterials. Her group has pioneered the use of bioinspired strategies to modulate properties of dentin and dentin-resin interfaces with high translational impact in the repair of dentin and disease prevention. Dr. Bedran-Russo has published over 145 peer-reviewed papers and 4 book chapters. Her research is supported largely by federal research grants. She lectures nationally and internationally is various topics in restorative dentistry and dental research. She is actively involved in the leadership of many dental organizations.

Luiz Bertassoni, DDS, PhD 
Associate Professor, Division of Biomaterials and Biomechanics, OHSU School of Dentistry

Synopsis: In this talk, the interface of tissue engineering, regenerative biology and restorative dentistry will be described as a means to stimulate a discussion about the future of dental care. Recent innovations in tissue engineering strategies to fabricate mineralized tissues with precision will be presented, and discussed regarding their ability to create dentin/enamel substitutes.
