 note = {application/pdf, In order to prevent pits and fissures caries and to improve sealant's retention rate, various cleaning methods on pits and fissures of newly erupted permanent teeth have been tested in the present study. Therefore, authors, using a brush-cone, tooth surface polisher (air flow) and a diamond fixed scratch point (D. F. S. P.) which was newly developed by our laboratory, cleaned the extracted human teeth which had no or slightly enameled caries. The authors also applied etching solution to the enamel surface of pits and fissures after cleaning. The effects of cleaning for the three cleaning methods and the resin tags of the sealant replicas were examined comparatively by using a scanning electron microscope. The results obtained were as follows: 1. When the pits and fissures were cleaned by brush-cone and tooth surface polisher, the residual deposit was found. However, when the cleaning of pits and fissures were done by a D. F. S. P., the residual deposit had been totally removed within the reach of the D. F. S. P. 2. From the observation of the etching effect on the enamel surface of pits and fissures and surface of sealant replicas, the penetration of sealant materials and the formation of the resin tags were found to be more certain when the D. F. S. P. was used. 3. With the use of the D. F. S. P., the improvement of the cleaning and etching effect resulted from slightly shaving the enamel. Therefore, the better retention of the pits and fissures sealant can be expected.},
