 note = {application/pdf, The application of fissure sealants have been highly appreciated to prevent the development of caries in immature permanent teeth such as first molars immediately after their eruption. However, the sealant often breaks and peels off due to the insufficient cleansing of the surface and pits and fissures of the teeth. We newly developed diamond fixed scratch point (DFSP) for the cleansing of pits and fissures of immature permanent teeth. In this study we aimed to have good prognosis of the condensation of fissure sealant and to suppress the progress of early fissure caries, and made a comparison of this method with conventional methods using brushcone and air-flow in term of the components of fissure debris after cleansing. The effects of cleaning for the three cleaning methods were examined comparatively by usting EMPA. The results obtained were as follows: 1. It was difficult to remove the contents in deep narrow fissures of types I and IK by the methods using brushcone or air-flow. Cleansing effect could not be recognized in the narrow base, for debris and organic residue were found. 2. DFSP developed by authors removed all of the organic debris in the fissures to result in excellent cleansing effect. 3. It was confirmed that extremely mild mechanical cleansing by use of DFSP brought good cleansing effect in deep narrow fissures which seemed to be unable to be cleansed sufficiently by the conventional methods.},
