Participants wanted for trial testing to explore painless caries treatment

BIRMINGHAM, Ala., USA: The University of Alabama at Birmingham School of Dentistry has announced that it will be offering patients with interdental caries a new, less painful treatment option as part of a new clinical trial. The new treatment, which entails infiltrating a preparation gel and then a liquid resin through a perforated plastic sheet between the teeth, allows dentists to treat cavities without administering local anesthesia or drilling, which is conventionally unavoidable to access the cavity.

The resin infiltration system is a commercially available product made in Germany and approved by the Food and Drug Administration, but is mostly being used only in clinical trials in the U.S. The university’s clinical research center is conducting the largest U.S. clinical trial of this product, enrolling 150 patients in the study.

“When we develop cavities between teeth, sometimes we have to go through the tooth, and we end up damaging healthy tooth structure,” said Dr. Augusto Robles, assistant professor and director of the operative dentistry curriculum at the university. “This new system allows us to skip the drilling and helps us preserve that structure.”

With the new procedure, the cavity is first cleaned by pushing a gel that prepares the surface to accept the resin infiltrant through the perforated sheet. The tooth is then filled by pushing a liquid resin through the perforated sheet. Finally, a dental curing light is then applied to the tooth to cure the resin.

Despite the apparent simplicity of the procedure, the treatment works only in between teeth or on smooth surfaces with small cavities. Some large lesions or those on the occlusal surfaces are not suited for this kind of system because the liquid resin cannot be used to build up shapes. Therefore, its application has to be very specific, Robles highlighted.

Dentists with patients interested in participating can advise their patients to make an appointment for a free 20-minute radiographic and screening assessment by email. Participation is free of charge.
