Abstract

The purpose of this study was to determine the effects of scaling and root planing with the modified P-10 CavitronR tip and curet instruments on root surface topography. Sample specimens included 20 periodontally involved extracted human teeth. Specimens were carved into a three split root design, each sample specimen acting as its own control. Control and experimental surfaces were randomly assigned to each specimen. Scaling techniques were applied on the assigned experimental surfaces for 2 minutes and 14 seconds. A scanning electron microscope was used to examine and micrograph root surface topography of experimental surfaces. Photomicrographs were evaluated using categories of root smoothness and scored by an examiner blind to the assigned specimen groups. Surface measurements from the modified ultrasonic P-10 tip were compared to surfaces hand scaled with curets. Data were analyzed at the 0.05 level of significance using a one-way analysis of variance and Newman-Kuels multiple comparison tests. Findings concluded that scaling and root planning with the modified P-10 resulted in smoother root surfaces than curets. However, both methods of instrumentation produced a significantly smoother root surface than the control group.
