What are the test for biocompatibility in dental materials?
Usage tests have been developed specifically for the evaluation of the biocompatibility of dental materials. The pulp and dentine test, the pulpotomy test and the endodontic usage test are widely recognized.
How do you evaluate the biocompatibility of dental restorative materials?
The MTT assay is the most common test to evaluate the cytotoxicity of dental materials [23,34,41,50,67,68,75,76] because it is a rapid and inexpensive method.
How is the biocompatibility of dental biomaterials evaluated?
New materials should be evaluated using initial cytotoxicity and secondary tissue screening tests prior to extensive animal experimentation testing and clinical trials. (iv)The test result should always be evaluated and interpreted with consideration for the manufacturers stated use for the material.
What do you mean by biocompatibility of dental materials?
ABSTRACT: Biocompatibility is the ability of a material to elicit a biological response, when applied to the body, without causing a chronic inflammatory reaction, foreign body reaction or toxicity, is related to the interaction of the cell or any biomaterial.
How do you test for biocompatibility?
Cell culture assays are used to assess the biocompatibility of a material or extract through the use of isolated cells in vitro. These techniques are useful in evaluating the toxicity or irritancy potential of materials and chemicals. They provide an excellent way to screen materials prior to in vivo tests.
Why should dental materials be biocompatible?
The oral cavity presents a harsh environment in which restorative and implant materials must be able to withstand. Aside for meeting the appropriate physi- cal and chemical standards, it is important that dental materials be biocompatible.
What is biocompatibility testing for medical devices?
Sensitization biocompatibility testing for medical devices is used to determine the allergic or sensitizing capacity to the repeated or prolonged exposure of a test material. Sensitization is characterized by delayed reactions that are not localized, independent of dose.
What makes a material biocompatible?
In a simple sense, materials are biocompatible when they exert the expected beneficial tissue response and clinically relevant performance. The other components of biocompatibility are cytotoxicity, genotoxicity, mutagenicity, carcinogenicity and immunogenicity.
Why is biocompatibility testing important?
Purpose of Biocompatibility Testing It is essential to make sure that the finished device is challenged to ensure that human use of the device does not result in any harmful effects.
Is amalgam biocompatible?
However, dental amalgam is probably the most controversial dental material because of biocompatibility concerns related to its high mercury content. Approximately 50% (wt.) of dental amalgam is elemental mercury, and a low level of it is released as mercury vapor that can be inhaled (US FDA, 2015).
What is the most biocompatible material?
Most biocompatible material is Titanium as it possess very good strength and low density value….REFERENCES:

How is biocompatibility determined?
The basic factors that influence biocompatibility are [3,5,8]: 1. Interaction with the surroundings—influence of cytotoxins, toxicological or allergic reactions, carcinogenic or mutagenic reactions, inflammatory processes, degree and quality of the biodegradation, contact with human blood.
