Abstract :
Objective: This study was done to determine if polishing the exposed root surfaces would decrease the surface
roughness after SRP.
Materials and Method: Twenty four single rooted teeth that were extracted due to periodontitis were selected. the
surface roughness was determined using a contact profilometer before SRP, after SRP and after polishing.
Results: The study showed that SRP resulted in a rough surface that was significantly reduced after polishing which
creates a less favorable environment for plaque accumulation.
Statistics: Intragroup analysis for change in surface roughness was done using t-test.Intergroup analysis to evaluate the
effectiveness of polishing agent was done using Kruskal- wallis test.
Conclusions: Polishing of the exposed root surfaces should be done mandatorily after SRP to prevent plaque
accumulation
