2022 IADR/APR General Session
The 100 th General Session & Exhibition of the IADR was held in conjunction with the 5th Meeting of the Asia Pacific Region. The virtual meeting was attended by individuals from around the world. Those attending the meeting could choose from among 207 Interactive Talk sessions, seven Focused Learning Sessions, three Hands-on Workshops, five satellite symposia, 52 Symposia, one Distinguished Lecture Series and a plenary.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 the IADR Distinguished Lecture Series speaker 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
In 2022, the hybrid layer turns 40 years old. Indeed, Nakabayashi et al., (1982) published the first article about the hybrid-layer formation theory, although Kramer and McLean in 1952 already observed a resin-penetrated zone within the resin-dentine interface created by the glycerolphosphoric acid dimethacrylate. This latter monomer was a revolutionary idea of Oscar Hagger (in 1949), who introduced it within the formulation of the Sevriton Cavity Seal; he had in fact invented a first sort of self-etching adhesive. Nowadays, most of the direct and indirect bonding procedures rely on the chemical bonding properties of functional monomers present in modern resin-based materials. However, even though dental adhesive systems have improved considerably over the last twenty years, several issues regarding premature reductions in bond strength, interface and marginal degradation are still a matter of concern. This symposium will attempt to bring together a number of demonstrations to show the current state of the art on the bonding durability in coronal and root-canal dentine. Moreover, durable adhesion of glassy matrix or oxide-based ceramics is crucial especially for minimally invasive reconstructions. It will be of key importance to highlight the fundamental principles of adhesion to different ceramics, along with the clinical protocols regarding to surface conditioning methods and adhesion promoters to be used in conjunction with different resin-based materials.

Learning Objectives
- Synopsis on dentine adhesion and nanoleakege as the pathway of degradation of hybrid layers created with self-etching or etch&rinse bonding approaches. Moreover, it will be demonstrated a new µTBS testing method to evaluate the advantages of selective-enamel etching.
- Analyse and discuss the fundamental principles of adhesion to different ceramics, and clinical protocols regarding surface conditioning methods.
- Analyse and discuss the clinical performance and longevity data of different bonding strategies to root-canal dentine
