The Variation of Lysozyme Activity in the Pocket Exudate and Clinical Findings on Scaling and Brushing-Instruction

The effects of scaling and brushing-instruction on the variation of lysozyme activity in the exudate of periodontal pockets and clinical findings such as gingival index, debris-index score, pocket depth (mm) and quantity of exudate in the patients with periodontal disease was investigated at weekly intervals for a month.The following results were obtained:1. The gingival index, debris-index score, pocket depth and quantity of exudate were more significantly decreased by scaling+brushing-instruction than only by scaling to treated patients.2. The lysozyme activity in the exudate of periodontal pockets was more significantly decreased by scaling+brushing-instruction than by scaling to treated patients.3. The lysozyme activity in the exudate of pkriodontal pockets was not found to have difference between the maxilla and mandibula.
