Abstract

Abstract: Background: The purpose of this study was to evaluate the results of adjunctive Er, Cr:YSGG laser therapy with scaling and root planing (SRP) as compared with SRP alone in the treatment of moderate to severe periodontitis. Methods: Fifteen adults (aged 27 to 65 years) with 90 nonadjacent sites probing ≥ 5 mm were treated in split‐mouth design with SRP and laser therapy versus SRP alone. Probing pocket depth (PPD), gingival recession (GR), clinical attachment level (CAL), plaque, and bleeding on probing were collected at baseline, 1, 3, 6, 9, and 12 months. Patient reported outcomes were measured to assess pain, sensitivity, and satisfaction. Results: Clinical improvements were similar for test and control sites with no statistically significant difference. At 12 months, the average PPD reduced from 6.1 to 4.2 mm for test and 6.2 to 4.3 mm for control sites. GR increased by 0.4 mm at test and control sites. CAL increased from 6.8 to 5.3 mm for test and 6.9 to 5.5 mm for control sites. Clinical outcomes were stratified by baseline PPD ( = 5, = 6 and ≥7 mm) and analyzed for number of sites that reduced (≤4 mm). No significant difference was observed when the baseline PPD was 5 or 6 mm. Test sites with baseline PPD ≥7 mm demonstrated a statistically significant difference in the percentage of reduced sites when compared with controls at nine ( P = 0.001) and 12 months ( P = 0.044). Conclusions: Adjunctive Er, Cr:YSGG laser therapy with SRP provides similar clinical improvement in the treatment of moderate‐severe periodontitis as SRP alone and may offer some advantage for deeper (≥7 mm) pockets.
