Seq# 198 - How Host-biomaterial and Microbial Interactions Guide Biomaterials Development

This session will be recorded and available through IADR CE On Demand after the meeting for Continuing Education Credit.  

Traditional dental materials developments have focused on physical and mechanical properties. However, dental restorative materials are not inert and interact with host and oral bacteria. The effect of host and microbial degradative activities on the materials and material-tooth interface, and the reciprocal effect of the materials and the material’s by-products on host and bacteria will be discussed. Recent development in addressing the above challenges by developing materials that are more resistance to host and microbial degradation and/or actively counteracting these activities will be presented.

4 experts in the field of development of dental materials and their interactions with host and bacteria will present recent development in the field. Dr. Michel Koo will discuss “Advances in Antibiofilm Materials and Surfaces; Dr. Sharukh S. Khajotia will discuss: “Why the Interface between Biofilms and Dental Biomaterials Matters”; Dr. Jack Ferracane will discuss: “The effect of biofilms and biomechanical loading on the tooth-composite interface”; and Dr. Yoav Finer will discuss: ”Interactions of dental materials with the host and bacteria”.

Learning Objectives:

  • Present recent developments in designing materials and surfaces with anti-adhesion and biofilm disruptive properties
  • Evaluate the effect of new antibacterial and antidegradative biomaterials on biofilm structure and properties under clinically relevant conditions
  • Recognize relevant biomechanical and degradative activities from host and bacteria and the effect of the material's composition on the degradation of the tooth and the tooth-restorative interface
  • The participants will gain valuable knowledge about biologically-relevant factors that are important when developing new dental materials, and how these can be assessed under physiologically-relevant conditions.
