Values are given as mean ± standard deviation or as a percentage. BOP, bleeding on probing; CALD, clinical attachment loss measured using the direct method; CALI, clinical attachment loss measured using the indirect method; ‘d value’, difference between CALI and CALD measurements; GBI, gingival bleeding index; PPD, periodontal probing depth; VPI, visible plaque index.
*
Data only for sites with gingival recession (n = 4, 757) from patients in the study sample (n = 75).
