Study of Dental Surface Roughness Resulting from Periodontal Debridement Instruments

Objectives: Comparing of the surface roughness resulted from periodontal debridement with manual, sonic and ultrasonic instruments. Materials and methods: The study samples consist of 40 single rooted teeth with advanced periodontal disease. It was divided into 4 groups: Ultrasonic group, Sonic group, Gracey curettes group which has been treated clinically and extracted immediately after the treatment, and Control group. Surface Roughness parameters have been measured by Surface Roughness Measuring Instrument, which included: Roughness average (Ra), Maximum height of the profile (Rt), Spacing mean (Sm), Rz and maximum Roughness (Rmax). The One way ANOVA test (P=0.05) was used for statistical analysis. Results: There were no significance statistical differences in parameters' roughness between experimental groups (P>0, 05). Conclusion: The periodontal therapy doesn't have any effect on surface root roughness regardless the type of used instrument.
