To evaluate the surface roughness of subgingival area of S. P. crown margins
subjected to various polishing procedures, the study was performed by use of
metallograph and surface roughness tester.
The following results were obtained;
1) Abrasive stone wheel produced the roughest surface (16.0¥ìm).
2) Final polish with rouge after polishing with rubber wheel, subsequent to abrasive
stone wheel, produced the smoothest surface (0.3¥ìm).
3) Both polish with rubber wheel after polishing with abrasive stone wheel, and polish
with pumice (coarse¡æmedium¡æfine) produced same surface roughness(0.8¥ìm).
