Effect of probing depth and bleeding tendency on the reproducibility of probing depth measurements.

The aim of this study was to determine the influence of the probing depth and the bleeding tendency on the reproducibility of probing depth measurements. Duplicate probing depth and bleeding tendency measurements were performed at 717 interproximal sites in 13 subjects. Analysis indicated that the factor probing depth had a larger effect on the accuracy of probing depth measurements than the factor bleeding tendency.
