The purpose of this study is to investigate the numerical values of sharpness of dental sealers and ascertain the following 3 points, using the cutting resistance detector as we previously reported. (1) Based on the cutting resistance data, is it possible to classify the sealers into 2 groups; sharp ones and dull ones? (2) Is it possible to notice the difference in the cutting quality of the brand-new scalers compared to the ones sharpened by the EASY-SHARP (Deppeler Inc.)? (3) Is it possible to promote this study in order to present the sharpness of sealers being caused by their physical properties? The brand-new sealers above 2.9 N accounted for 62.5% (525) of all cutting samples (840). In the case of the ones sharpened by the EASY-SHARP, there was a 28.1% increase (in total; 90.6%, 761) in the scalers that measured above 2.9N. This means the ones above 2.9N could be classified as "sharp" and the ones under 2.9N could be classified as "dull". As a result of our experiments, we can conclude by saying that the cutting quality of dental scalers could be evaluated quantitatively by physical change of their resistance.
