Like all concerned dentists, Dr. Plascyk is concerned about the interaction of dental materials with the biology of his patients (biocompatable). Dr. Plascyk uses quality filling materials that have been reviewed and researched by his peers for the best clinical performance. In addition to the clinical performance of materials, many patients who seek Dr. Plascyk's care are concerned about the biocompatibility of the materials.
Some people use the unofficial term of "biologic dentist" or "biological dentist" to describe dentists who are more concerned about the biocompatibility of dental materials. In Dr. Plascyk's opinion, all dentists using quality dental materials that have excellent clinical performance are biological or biologic dentists. This is because the materials that have excellent clinical properties (color stability, polishablility, esthetics, wear) tend to be more chemically stable also. Better chemical stability means less corrosion and breakdown of the material in the body.
Here is one definition of biocompatibility:
"Biocompatibility has been defined as the state of mutual coexistence between
the biomaterials and the physiological environment such that neither has an
undesirable effect on the other. It is the ability of a material to perform with
an appropriate host response in a specific application. This means that the
tissues of the patient that comes into contact with the materials does not
suffer from any toxic, irritating, inflammatory, allergic, mutagenic or

There are three types of compatability concerning dental materials. These include general biocompatibility, immunologic biocompatibility and bio-energetic biocompatibility.
General biocompatibility: Certain materials are not biocompatible at all. These materials are toxic or poisonous to cells in every person. These materials would not be biocompatible for any one.
Bio-energetic biocompatible: Some health care providers believe in meridians in the body. Meridians are pathways of energy flow in the body. There is no physically verifiable anatomical or histological basis for the existence of these pathways. Nonetheless, according to health care practitioners who believe in this, certain energy incompatible dental materials can interfere with the healthy energy flow of these meridians and make someone less healthy. Electrodermal Screeening (EDS) and Applied Kinesiology or Muscle Testing is used by certain health care practitioners to determine how dental materials react with the body on an energy level
Immunologic Biocompatability: This is the compatibility of a dental material on an immunological level. In order for a dental material to elicit an immunologic or allergic response it must corrode or chemically react with its surroundings (become bio-available). The chemicals produced in this corrosion reaction will be different than the original molecules in the dental material. The Clifford Reactivity Test is a blood test that determines if your body has made antibodies to the corrosion product of a particular dental material. Ideally, you do not want to have antibodies against dental materials that are in your mouth. The results of the Clifford Reactivity Test will label materials as S (satisfactory) or NS (not satisfactory) based on whether a person’s serum had antibodies against the dental material. The official name of the test used in the Clifford Reactivity Test is Immunoassay Qualitative By Percipitant Method. The official medical procedure code (CPT) is 83516. It is used in the Rubella Test, baterial identification and used for detection of exposure to toxins and noxious materials. The test is also used for orthopedic surgical replacements.The Clifford Reactivity Test is available to Dr. Plascyk’s patients if they want it. Dr. Plascyk does not require this test before dental treatment is completed. The typical patient requesting this test suffers from chronic or serious medical problems or patients that have been diagnosed by a physician with multiple chemical sensitivity. For more information about the Clifford test go to www.ccrlab.com. Dr. Plascyk does not charge for this test. You are billed directly from the Clifford group.
The International Academy of Oral Medicine and Toxicology (IAOMT) has a term for dentists concerned about biocompatibility of dental materials. They call them "biological dentists". They define a biological dentist as follows:
"Biological dentists recognize the impact of toxic materials and relate it to dental
and physiological health. These dentists are concerned with the integrity of the
oral cavity and use materials and procedures in their practices that are systemically
When I speak about biocompatibility I am focusing on general biocompatibility and immunologic biocompatibility (see above). If a patient determines (through their own means of testing) that they are not bio-energetically compatible with materials that I routinely use, then I will not be able to treat them.
Many of our new patients are concerned about the biocompatibility of dental materials. Therefore, they want to know the ingredients of the dental materials that I use. However, I explain to patients that the starting compounds in a dental material do not determine the biocompatibility of the material. It is the chemical stability of the material in the oral environment that determines whether it is biocompatible or not. Fortunately, the vast majority of traditional dental materials are extremely stable in the oral environment. Another way of stating this is as follows:
No one can claim that any dental material is not biocompatible just
because it contains certain ingredients (again, just considering
general and immunological biocompatibility here). The initial
ingredients do not determine the compatibility of a dental material.
The corrosive by-products (which are chemically different from the
original chemical structure of a material) and the corrosion rate
(or half life) are the most important information in determining
whether a dental material is compatible or not. If a material remains
chemically intact and does not break down on a molecular level to
any consequential degree, it cannot harm you. The corrosive by-
products (if not compatible) have to be bio-available to the cells in
enough quantity to cause a problem for your body.
