ABSTRACT
BACKGROUND: It is well known that following root surface debridement (RSD) residual deposits remain. 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 utilizing endoscopic visualization was more effective in improving clinical and radiographic parameters as compared to root surface debridement (RSD).
METHODS: Thirty-eight subjects were randomised into RSD with perioscope (n = 19) or RSD only (n = 19) groups. A full mouth evaluation included probing pocket depths (PPD), clinical attachment levels (CAL), bleeding upon probing (BOP) and plaque scores (PI) recorded at baseline, three and twelve months and compared between groups. Radiographs were taken at sites with deepest pockets at baseline and 12-months and the change in radiographic bone levels (RBL) compared. An independent samples T-test was used to assess statistical significance.
RESULTS: Both groups had significant improvements in clinical outcomes. The test (T) group had a significantly lower percentage of PPDs 7-9 mm at three (0.72±1.2%) and twelve months (0.5±1.0%) as compared to the control (C) group (2.25±2.9%; 1.84±2.3%). At twelve months, the test group recorded a significantly lower mean PPD (T: 2.70+0.2 mm; C: 2.98±0.4 mm), BOP% (T: 4.3±3.2%; C: 11.95±7.1%), PI% (T: 25.61±3.9%; C: 30.11±6.3%) and less change in gingival recession (T: -0.13±0.2 mm; C: -0.50±0.6 mm) (p<0.05). More radiographic bone gain was observed in the test group (0.69±0.3 mm) as compared to the control group (0.49±0.2 mm). This was also observed around multi-rooted teeth (T: 0.83±0.45 mm; C: 0.46±0.36 mm).
CONCLUSION: The adjunctive use of the perioscope provided a slight benefit to the outcomes of non-surgical therapy particularly at deeper probing depths. This article is protected by copyright. All rights reserved.
