The purpose of this study was to evaluate the exent of the penetration of a periodontal probe during clinical assessment of periodontal pocket depth and the relationship between loss of attachment and subgingival plaque in advanced periodontitis. 22 teeth above second degree tooth mobility were selected. Clinical periodontal pocket depths were compared to the distances from gingival margin to the apical border of the plaque, and the distances from gingival margin to the occlusal border of attached connective tissues, and the distances from the apical border of the plaque to the occlusal border of attached connective tissues as evaluated on extracted teeth. The obtained results were as the follows: 1. Clinical periodontal pocket depth were deep on the average 0.77mm (±1.33) than the distance from gingival margin to the occlusal border of attached connective tissues as evaluated on extracted teeth. 2. The mean distance from the apical border of the plaque to the occlusal border of attached connective tissues as evaluated on extracted teeth was 0.30mm (±0.53) 3. The distances from the apical border of the plaque to the occlusal border of attached connective tissues as evaluated on extracted tooth were decreased as pocket depths were increased. 4. The distances from the apical border of the plaque to the occlusal border of attached connective tissues as evaluated on extracted tooth were decreased as loss of attachment were increased.
