Building up tooth preparations for full crowns--2000.

Many factors influence whether teeth planned for crowns or fixed prosthesis abutments need to be built up. Teeth may now be treated more conservatively with minimal fillers because of the greater strength of current cements, including hybrid ionomers and resins. Teeth planned as fixed prosthesis abutments require more remaining tooth structure and greater buildup strength than those designed for single full crowns. It appears that crown buildup is still necessary, but this procedure is needed less frequently than it was in previous years. Fillers can be used to fill holes left when previous restorations were removed, and are more commonly placed than build-ups.

The inevitable maladies of the mature dentition.

Patients who are in their mature years should be advised about the numerous ways in which teeth and supporting structures degenerate in the later years of life. This knowledge will allow patients to make special efforts to prevent, reduce, eliminate or treat the oral problems associated with aging.

Discoveries of importance in restorative dentistry over the past 40 years.

The advancements in restorative dentistry over the past several decades have been impressive. It is now possible to prevent dental caries on a predictable basis. If prevention is not carried out in early life and teeth are lost, it is now possible to restore mutilated or missing teeth with high efficiency and effectiveness. The future for restorative dentistry is extremely bright and has never been better in its history.

The high-speed handpiece dilemma.

High-speed handpieces are perhaps the most important piece of equipment in a dental office. They have provided more than 40 years of great service to dental patients. However, handpieces' lack of ability to withstand the heat involved in sterilization has caused significant problems for practitioners. Improvements and changes are needed immediately. Manufacturers, the profession needs your help.

Sorting out the confusing array of resin-based composites in dentistry.

Several categories of useful restorative resin-based composites have evolved over the past 40 years. Some of them are indispensable; others are clearly not as necessary. It is possible that dental practitioners could practice successfully with only one type of resin-based composite: hybrid. But each type added to a clinical armamentarium provides possibilities for better esthetic results, easier and better clinical placement, or better long-term function. Undoubtedly, even more categories of restorative resin-based composite will evolve in the future. Dentists are advised to observe them carefully before buying to see if they satisfy any additional needs.
