Calcium amount in the deposit on clinical crown of 1|1 during one month will be considered to express the individual activity of supragingival calculus formation (ACF). It will be more reasonable that geometric mean is adopted in the case of statistical treatment of the results, when the test for some preventive measure against calculus formation will conduct with some population group.<BR>Application of a dentogingival splint has been proved to be a new effective measure to prevent supragingival calculus formation. Eventhough the tightness of the splint depends upon the material and method to prepare it, it is the most important requirement to insure its effectiveness.
