Should teeth be built up for crowns?
Article Abstract:
A variety of methods for preparing teeth before placing crowns are discussed. The major methods of preparing teeth for crowns are with the use of composite resins, dental amalgams, glass ionomers and glass ionomer resins. There are also a number of ways to attach the build-up materials to the tooth. These include mechanical means such as the use of channels, grooves, metal pins or bonding agents. Some materials also have molecular bonding agents in them. The two most popular methods of preparing teeth are with bonded amalgam or composite resin. Glass ionomer resins are new and show promise, but further research is needed before they can be recommended unreservedly.

Overcoming challenges with resin in Class II situations
Article Abstract:
Careful placement and finishing techniques can improve the performance of composite resin in Class II situations. Since 1985, improved resin materials, which can be tinted to match tooth color, offer an alternative to traditional silver amalgam fillings. Although resins do not wear as long as amalgam, their longevity is clinically-acceptable. Techniques to improve resin performance are described, and the use of resin is encouraged.

Compomers vs. resin-reinforced glass ionomers
Article Abstract:
Compomers are replacing resin-reinforced glass ionomers (RRGI) for many tooth restorations. Both of these compounds release fluoride, which prevents cavities from developing. RRGI comes in the form of a powder and liquid which must be mixed together. Compomers come in the form of putty in a syringe and are thus easier to use. However, compomers must be light-cured and therefore cannot be used in areas too deep to be light-cured.
