Improvements in methods of periodontal probing: comparison of relative attachment level data selected by outlier reduction protocols from Florida disc probe measurements

Objectives:  To compare relative attachment level data (RAL) selected by the Option‐4 algorithm (O‐4), Modified Option‐4 algorithm (MO‐4), Option‐3 method (O‐3) and Double Pass method (DP) from a common dataset and to determine the most efficient method in eliminating outliers. Material and methods:...

Description
Summary:Objectives:  To compare relative attachment level data (RAL) selected by the Option‐4 algorithm (O‐4), Modified Option‐4 algorithm (MO‐4), Option‐3 method (O‐3) and Double Pass method (DP) from a common dataset and to determine the most efficient method in eliminating outliers. Material and methods:  A single clinician recorded full mouth RAL with the Florida Disc Probe on four occasions over 6 months in 16 subjects (mean age 48.1 years) with untreated moderate Chronic Adult Periodontitis (mean Probeable Crevice Depth 2.9 mm). Results: 2312 sites were available for analysis. Within‐visit correlation coefficients for the two selected RAL measurements were 0.98 (P
