试验目的

1. Study Objectives 1.1. Primary Objective 1.1.1. To compare the primary clinical outcome variable, i.e. change of clinical attachment level, and secondary clinical outcome variables at primary surgical site. i.e. periodontal defects with periodontal pocket depth ≥6mm and an intra-bony component ≥3mm, treated by Periodontal Endoscope Assisted Root Surface Debridement or conventional periodontal surgery - Open Flap Debridement. 1.2. Secondary Objectives 1.2.1. To compare the clinical outcome variables at secondary surgical site, i.e. periodontal defects with periodontal pocket depth ≤5mm, treated by Periodontal Endoscope Assisted Root Surface Debridement or conventional periodontal surgery - Open Flap Debridement. 1.2.2. To compare the patient-centered outcomes, during intra-operative and recovery period, from Periodontal Endoscope Assisted Root Surface Debridement and conventional periodontal surgery - Open Flap Debridement. 1.2.3. To compare the time required for Periodontal Endoscope Assisted Root Surface Debridement and conventional periodontal surgery - Open Flap Debridement.
