To accomplish these goals, all of our tests are performed in a way that simulates actual clinical procedures as closely as possible. For example, our bond strength tests are done using the exact same equipment, materials, and procedures as we recommend and use on patients treated by our staff. In addition, some of our bond strengths are determined immediately after curing a specimen, since most of us begin finishing a restoration as soon as our curing light goes off. If we start to stress a restoration immediately, we need to know which adhesives are strong enough at that point, not just one day or one week later. In other words, we need both immediate and delayed testing.

All tests performed in the RRL are done by dentists - not by students, not by researchers without a dental degree, and not by any support personnel. This policy does not mean to impugn the competency of these individuals. But, since dentists are the only persons that are legally allowed to restore teeth in most areas of the world, we decided it is only the results of dentists that really matter when it comes to patient care.

The one exception to this policy is when we test laboratory-based materials such as ceramics and indirect resins. Dental laboratory technicians may be involved in testing those materials when it comes to the procedures typically performed in a lab. This includes simulating the procedures that are done to the bonding surface of a restoration before sending it to the dentist. Sandblasting and etching with hydrofluoric acid are two such examples.

Results of our tests are published in REALITY ONLINE and issues of REALITY NOW. Full detailed protocols are posted on this website. This section is password protected for members-only.

The Goals of the RRL

1. To conduct scientifically valid and reliable research in a clinically relevant manner.

2. To provide solutions for common, everyday clinical problems.
