Effect of plaque and calculus removal by scaling and root planing with or without perioscopy in chronic periodontitis

Objective Compare the effect of plaque and calculus removal by scaling and root planing (SRP) with or without perioscopy in chronic periodontitis. Methods Sixteen subjects with 26 loosening teeth were randomly divided into SRP+perioscopy group (groupA, n=13) and SRP group (group B, n=13). Each tooth was extracted after 10 mins’ SRP. Methylene-blue were used to show the residual calculus on four tooth surfaces (buccal, lingual, mesial, distal). A digital camera and image analysis software were used to determine the percentage of residual calculus. Results The percentage of residual calculus in group A and B were (8.34±1.70)% and (13.02±3.36)% (P0.05) respectively. Smoking, bleeding on probing (BOP), and probing depth (PD) between two groups were related with the residual calculus percentage. Conclusion The use of perioscopy can resulted in a statistically significant overall improvement in calculus removal in SRP.
