This book provides a comprehensive and scientifically based overview of the biocompatibility of dental materials. Dr. Yuriy May, voted Hartford’s Top Holistic Dentist, uses several dental material tests to ensure that the dental materials selected for his patients are biocomptatible with their unique biochemistry, avoiding unnecessary negative reactions. Biocompatibility test protocols include those for cytotoxicity, hemocompatibility, genotoxicity, irritation, implantation, sensitization, and system toxicity. Biocompatibility Test for Dental Materials The reactive or non-reactive effects to dental materials may vary in each of us, especially in patients with special health concerns.In my office, everyone is tested for biocompatability of potential dental materials, to develop their “dental menu” of dental materials for use, when dentistry is required. 4 grams if surface area cannot be determined 1 – 2 weeks GPMT (Kligman) Sensitization material thickness of ≥0.5 mm = 180 cm2. The new standard is less rigid and may even enable manufacturers to skip some biocompatibility tests altogether—as long as they can provide solid evidence for doing so. Material interactions may cause a medical device to fail biocompatibility testing. It includes testing of pharmacological agents that are an integral part of the device under test.

TING OF DENTAL MATERIALS The selection and evaluation of any material or device intended for use in humans requires a structured assessment. This procedure involves sending a sample of the patient’s blood to a lab for analysis where technicians test the blood serum against thousands of dental products and materials to ascertain if they elicit an immune response or not. As well as the internal chemical structure, the chemical properties of the surface frequently determine the degree of biocompatibility.
