The first ICNARA conference (International Conference on Novel Anticaries and Remineralizing Agents) was held in Chile in January, 2008, and the proceedings were published in Advances in Dental Research (Volume 21, 2009). That issue of Advances summarized the state of the science and set a research agenda for the future for two key components of caries management, namely, antibacterial agents and remineralizing agents. The second conference (ICNARA 2, January 2012) provided an update on science and new directions for research and clinical practice. Over the past decade, renewed efforts have been made across the world to establish proven methods of caries risk assessment and to provide direction for improved methods of caries management based upon risk levels. Evidence-based caries risk assessment tools are now available. The need for improved therapy to reduce the bacterial challenge that initiates the caries process, and to enhance remineralization, is now very clear. Fluoride therapy alone is insufficient to control the caries process in high-risk individuals. New remineralizing and anticaries products and new delivery systems are in development, and ICNARA 2 presents future technology for the management of dental caries.
