An electrochemical study on the human dental enamel with special reference to isoelectric point.

abstract：:This paper aims to present a simple overview of potential new diagnostic methods for dental caries. There are several novel methods of caries detection (with potential application to diagnosis) which have been proposed in the last few years, in addition to those that are gaining some commercial exposure and clinical a...
