Periodontal endoscopy has provided a method of directly visualizing root surfaces during periodontal debridement in an intact pocket without the need for surgical incision. The aim of this study was to determine if periodontal debridement using endoscopic visualization was more effective in improving clinical and radiographic parameters as compared to RSD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thirty\u2010eight subjects were randomized into RSD with perioscope (<jats:italic>n<\/jats:italic>\u00a0=\u00a019) or RSD only (<jats:italic>n<\/jats:italic>\u00a0=\u00a019) groups. A full\u2010mouth evaluation included probing pocket depths (PPDs), clinical attachment levels (CAL), bleeding on probing (BOP) and plaque scores (PI) recorded at baseline, 3 and 12 months and compared among groups. Radiographs were taken at sites with deepest pockets at baseline and 12\u2010month and the change in radiographic bone levels (RBL) compared.
