This edition has been updated to provide an all-inclusive perspective of the entire syllabus of Operative Dentistry as prescribed by various universities in the country. Both the fundamental concepts and the recent developments in the field have been emphasized adequately. Most of the chapters have been extensively reviewed and revised to benefit the students. The chapters on Smart materials and 3D printing in Conservative Dentistry are new additions to this edition. The original style of the previous editions including boxes and tables has been retained to facilitate easy reading and many new photographs have been added to illustrate new clinical concepts.
