In an attempt to determine how the degree of roughness of the polished dentin planes would be affected by several factors under root planing, quantitative measurement was made statistically.
The results obtained were as follows:
1) On the roughness of the dentin surface under hand scaling, a statistical analysis showed that strokes proved to the largest affecting factor, followed by applied force.
2) On the roughness of the tooth surface under two different types of ultrasonic sealers, it was found that ODONTOSON resulted in more rough rather than CAVITRON.
In ODONTOSON, a statistical analysis showed that strokes proved to the largest affecting factor, followed by applied force, and the interaction of applied force and strokes.
