Twenty-four-month clinical trial of visible-light-activated cavity liner in young permanent teeth.

A clinical study of young permanent teeth for twenty-four months evaluated the use of a new product, VLC-Dycal, as a cavity liner. VLC-Dycal is a light-activated calcium hydroxide cavity liner. After twenty-four months, VLC-Dycal had a 91 percent success rate used as a liner with young permanent teeth. From the fifty-four teeth evaluated at twenty-four months, only five were failures. Failure occurred more frequently with DPC. Of the five teeth that became devital over the twenty-four months, three were DPC. The success rate for DPC was 70 percent. IPC had a success rate of 85 percent. None of the CCR procedures failed in the study. Because of the improved physical properties, VLC-Dycal was evaluated in a clinical trial for biological properties and proved to be a useful cavity liner for young permanent teeth.
