[Relevance of the Periotest as a function of root shape and cross-section].
In the laboratory extracted teeth were provided with an artificial periodontal ligament. Subsequently periotest values were measured around the complete circumference of the crown. When plotted in a graph the relationship between root cross-section and damping value can be demonstrated. At the present level of knowledge only comparative measurements, in particular in teeth with low periotest values, seem reliable.
