Abstract: Periodontal endoscope is a minimally visual non-surgical adjunctive method for periodontal treatment. The use of periodontal endoscope can improve clinical results in contrast to traditional scaling and root planning (SRP) alone. In this paper, a patient with stage Ⅲ grade B periodontitis and malocclusion (Angle Class Ⅱ) who had deep residual periodontal pockets (PD≥5 mm) after traditional SRP obtained significantly improved periodontal results after adjunctive use of periodontal endoscopic.

Key words: periodontitis stage Ⅲ grade B, periodontal endoscope, periodontal basic treatment, malocclusion
