2021 IADR/AADR/CADR General Session

The 99th General Session & Exhibition of the IADR was to be held in conjunction with the 50th Annual Meeting of the American Association for Dental Research and the 45th Annual Meeting of the Canadian Association for Dental Research, from July 21-24, 2021 as a Virtual Experience.

The recordings in this library from the meeting are a selection of the science that was to be presented as part of the General Session. These recordings give you the opportunity to participate in the meeting and hear from leading researchers. The recordings include IADR Distinguished Lecture Series speakers, the IADR Academy and symposia from a collection of scientific groups and networks.

This session can be purchased as part of the full meeting recordings within the product bundles

Session Description 
Dental biomaterials, such as methacrylate-based resin composites and dental implants, face a significant challenge after placement: surviving in the complex host environment of the oral cavity composed of saliva, epithelial cells, the innate immune system, and a plethora of microbial cells organized within the dental biofilm. This environment challenges the integrity of dental biomaterials, leading to a higher than desirable failure rate and shortened service life. Progress in dental materials research towards enhanced service life can be achieved by appropriate modeling of the biomaterial-biofilm interface that includes relevant oral microbes and biofilm growth conditions. However, standards for testing the influence of dental biofilms on biomaterials and vice versa are currently missing, thus hindering advancement in materials development.

The symposium will address the imminent need for a consensus for adequate models and set forward the discussion on how to develop methods to test biomaterial-biofilm interactions. Current problems will be identified and addressed from the microbial and dental materials side, combining the expertise of both fields with the goal to set experimental standards for biomaterial-biofilm interface research.

Learning Objectives
  • Identify the current problems and limitations of dental materials testing and understand the process of methods standardization and define a desirable outcome for the integration of biological and dental material aspects in the development of future biomaterials.
  • Critically evaluate test methods for current materials and how they could be modified for the development of future materials and testing modalities.
  • Identify microbiological determinants of biofilm formation and how they might influence dental materials.
