MI concept has been propagated clinically according to the advancement of the adhesive materials and tounderstanding of the caries development. MI diamond points were designed based on this concept to remove theinfected lesions thoroughly, preventing the cavities from extension beyond the sound tooth tissues. The aim of thisstudy was to introduce and evaluate the clinical performance of the experimental MI diamond points, which couldbe expected to totally support the adhesive restorations procedures. This MI diamond point system consists of thepreparation and the finishing & polishing kits. The preparation kit comprises three sizes of round-type long-neckpoint and three sizes of pear-shaped long-neck point. As a result, these points were very useful due to the smallcutting head to remove the active lesions only preserving the sound tooth tissues, to the long neck to access to thedeeper cavity floor visibly, and to the strong mechanical property that did not cause the neck fracture of pointbody. Further, the finishing & polishing kit, consisting of the eight kinds of smooth-cut finishing points and thesilicone point “compo-master” for polishing, could be available for almost all cases of finishing procedures of theadhesive restorations and could contribute to shorten the treatment time.
