Current developments in dentin bonding systems: major progress found in today's products
Article Abstract:
New procedures and materials have improved dentin bonding systems. Dentin bonding systems were first introduced to restorative dentistry in the late 1960s. Restorative dentistry is the restoration of existing teeth that are defective through disease, damage or abnormal development. Dentin bonding systems involve the bonding of different types of materials to the surface of etched tooth enamel. Cervident was a bonding system that was introduced in the 1950s. This system was characterized by detachment of the bonding material from the tooth after a short period of time. Scotch Bond was introduced as a new type of bonding material, but it failed to meet original expectations. Bonding materials with increased strength were introduced in the early 1980s. Several new adhesives have increased bonding strength and protect the tooth from microorganisms.

New developments in resin restorative systems
Article Abstract:
Polymers are being developed that can compete with ceramic restorations. Polymer resins were introduced in the 1950s and '60s. They can be used for crowns, dentures and as pit and fissure sealants. In the 1990s, several polymer resins have been introduced which are more resistant to wear. They include Artglass, Belleglass HP and a polymeric rigid inorganic matrix material, known as PRIMM, developed by Medical Equipment Distributors. Unlike ceramics, polymers can mold themselves to better fit the space they occupy.

Is it possible to control the directional shrinkage of resin-based composites?
Article Abstract:
Resin-based composites will shrink toward the center of the restoration if etching and bonding procedures are not used. If etching and bonding is used, the preparation will shrink toward the walls of the preparation. The direction of shrinkage is not dependent on the method of curing.
