The purpose of this study was to investigate the effect of instrumentation with curette, ultrasonic instrument and CO_(2) laser on root surface and result of rubber cup polishing. Eighteen extracted human teeth were used in this study, and divided into six groups, and instrumented as follows. GroupⅠ : Use of curette only Group II : Use of ultrasonic instrument only Group Ⅲ : Use of CO_(2) laser only Group Ⅳ : Rubber cup polishing followed by curette Group Ⅴ : Rubber cup polishing followed by ultrasonic instrument Group Ⅵ : Rubber cup polishing followed by CO_(2) laser After observation of the teeth with scanning electron microscope, the results obtained were as follows : 1. In normal teeth, under same condition, curette produced smooth root surface while ultrasonic instrument and CO(2) laser did not remove calculus completly. 2. In the comparison of polishing between three groups on each root surface, the use of ultrasonic instrument and CO_(2) laser resulted in significantly smoother root surface than curette.
