Conference paper


It is needless to say that diagonosis for dental caries is the most important aspect in dentistry, and roentgenographic examination has been the essential diagonostic method for dental caries. However, strictly speaking, even the roentgenographic examination do not have enough resolution to detect a fine decay in the teeth of primary caries, and the multiple roentgenography is disliked for the safety reasons1). From the results of the spectral analyses of enamel, dentin and dental caries2), the authors had presumed that the remarkably different photo-thermal reaction to laser exposure in each dental structure may lead to a new diagonostic technique for dental caries.
