Dr. Mitra, an associate professor, introduces a session on cavity liners, bases, and varnish, emphasizing their importance in dental exams. The session covers the definition, classification, composition, and clinical applications of these materials. It also discusses the importance of protecting the pulp through chemical, electrical, thermal, and mechanical means. The session highlights the role of liners and bases in providing pulp protection and their placement between dentin and restoration.
