Aim: The aim of this study was to compare the efficacy of various magnifying tools in periodontal mechanotherapy. Materials and Methods: A total of 30 single-rooted extracted teeth were equally divided into six groups. The root surfaces were subjected to manual as well as ultrasonic instrumentation under unaided eye, magnifying loupes, and dental operating microscope (DOM). Then, the teeth samples were evaluated for the surface properties and for the presence of smear layer with a scanning electron microscope using magnification of ×100 and ×3000. Statistical Analysis: Data were subjected to statistical analysis using Kruskal–Walli's Analysis of variance and Mann–Whitney's test. Results: The mean roughness and loss of tooth substance index scores for the manual instrumentation performed under unaided, loupe, and surgical microscope were 1.8, 1, and 1, respectively. The mean scores for the power-driven instrumentation performed under unaided, loupe, and surgical microscope were 1.2, 1.2, and 1, respectively. Statistically significant (P < 0.05) difference was found when root planing was performed by hand instrumentation under DOM when compared to unaided vision. Comparison between manual and ultrasonic instrumentation was nonsignificant (P > 0.05) under magnification. Conclusions: All treatment modalities were effective in mechanical debridement of the root surface. The result favored the use of ultrasonic instrumentation as compared to manual instrumentation under unaided vision. Whereas under magnification, both manual instrumentation and ultrasonic instrumentation produced similar root surface smoothness.
