Welcome to the PREP panel

The rapid pace of innovations in new dental materials and techniques, and the short marketing lifetime of new products, makes it hard for a busy practitioner to assess the latest developments in dentistry.

The PREP panel is a group of thirty three experienced General Dental Practitioners (GDPs) who assess new materials and products in the busy surgery environment, and report on their suitability for modern dental practice.

We are paid by the manufacturers to test their products, but we publish exactly what we find. We have published the results of over 50 products since our formation in 1993, with each product evaluated by between 10 and 15 of our dentists. Also the results of one, two, three and five year trials of restorative materials have been published in peer-reviewed journals.

The PREP panel members work all over the UK (together with one member in Germany) and in all types of General Practice.

This website contains the reports of the evaluations and trials of currently available materials and as such we hope will be a valuable resource for the busy GDP.
