American dentists are utilizing more amalgam restorations than composites, according to the results of two studies in the June issue of the Journal of the American Dental Association.
The results are surprising, considering the improvements in resin-based technology and the possible harmful effects of amalgam. Despite this information, amalgam is still a material utilized by dental schools.
Dr. Sonia K. Makhija, an assistant professor of dentistry at the University of Alabama, and her team analyzed nearly 5,600 restorations of carious lesions in the posterior teeth. Amalgam was used in more than 3,000 of the restorations, while composite was used for the rest. This study focused solely on amalgam and composite, not any other material.
