In an attempt to determine how the degree of roughness of the polished dentin planes would be affected by several factors under root planing, morphological studies were made scanning-electoronmicroscopically. The results obtained were as follows: 1) Under hand scaling, the folds were observed on the dentin surface followed by 2 strokes of all aplied forces and instrumental angles. 2) The folds were smooth increasing with the strokes, but were gradually observed that the depth of defect was larger under the line-spot technique. 3) On the roughness of the tooth surface under two types of ultrasonic sealers; in CAVITON, the particles of an indeterminate form were observed, on the other hand, many craters were observed in ODONTOSON.
