This textbook covers all aspects of materials science relevant to the practice of dentistry. It is aimed primarily at undergraduate dental students, although it will also be useful for practising dentists, dental technicians and dental assistants. The 9th edition has been extensively revised to include the many advances in dental materials and their use that have occurred during the past nine years. The chapters on Resin-based filling materials and Adhesive restorative materials have been expanded significantly with new coverage of fibre reinforcement of composite structures and polymerisable luting agents. A brand new chapter has been added on endodontic materials.
