Probing depth (PD) is measured at 2, 4 or 6 sites per tooth. We sought to ascertain whether or not more measurements increase the sensitivity of assessing the severity of periodontitis. 2 probings compared with 4 probings per tooth resulted in 68% sensitivity for PD greater than 2 mm and 77% for PD greater than 4 mm. The mesio-buccal PD explains only 16% of the variance of the buccal/oral PD. Comprehensive examination of pockets should consist of a minimum of 4 probings per tooth.
