Increased knowledge about the carious process and the beneficial effects of multiple fluoride application has resulted in a decrease in caries incidence. Likewise, the increasing professional emphasis on caries prevention is as important as the recent technologic and scientific advancements. The recognition that most dental disease is preventable has resulted in better patient self-care and more conservative efforts by dentists in treatment. Increased research on biomaterials has led to the introduction of vastly improved dental materials. Developments in impression materials and gold foil and advancements in knowledge about liners and sealers are also factors that have resulted in better care and treatment for patients. Advances in metallurgy have resulted in a variety of improved alloys that are either already available or are being developed.
Corrosion-resistant amalgam alloys have been developed that will enhance the oral health of the population by providing longerlasting restorations.All of the factors just mentioned have played an important role in the development of operative dentistry. They have resulted in a reduction of the incidence of caries and a more conservative and effective approach toward treatment, with the ultimate result of improved oral health for all populations.
FACTORS AFFECTING THE FUTURE DEMAND FOR OPERATIVE DENTISTRY
Because of the dynamic status of operative dentistry,many future developments and advancements will undoubtedly occur. These advances in technology, science,and materials will have a significant effect on the future practice of and demand for operative dentistry. However, there are other factors that will also affect the future of operative dentistry. To project the future demand for operative dentistry treatment, both current and projected dental health in the United States must be identified. This necessitates a
projection of demographic changes, economic factors, and dental health and the effect of these on the future demand for dental services.
