The objective of the present study is to evaluate the surface texture of root after hand instrumentation with Gracey curette, After Five curette and Mini Five curette.Patients having chronic periodontitis and scheduled for extraction were randomized into four groups. Scaling and Root planing was performed by different curettes. Group 1 didn't under go any instrumentation. Group 2 was instrumented with Gracey curette, Group 3 with After Five curette and Group 4 with Mini Five curette. These hopeless teeth were then extracted atraumatically and the specimens were processed and analyzed under a Scanning Electron Microscope. "Roughness and Loss of Tooth substance index" and "Smear layer index" was evaluated using the Scanning Electron Microscope photographs.Means and frequencies were reported using SPSS Version-21.Cross Tabulation was made between the test groups (Control, Gracey Curette, After five and Mini Five) versus "Roughness and Loss of Tooth substance Index" and "Smear Layer Index". Chi square test was applied to see the grade distribution among groups. Frequencies were reported in percentages and means. P. value of 0.05 or less was considered as significant.
