Lead contens have been determined coloimetrically by the dithizone method on the dental calculi taken from the mouth of seven subjects who were daily exposed to lead materials in the printing bureau of a newspaper office. The results were summarized as follows. 1) The dental calculi used in this study ranged from 15.1 to 57.0 mg in weight. 2) The light transparency of the dental calculi ranged from 57 to 87 per cent. 3) The lead content of the materials ranged from 9 to 833 gamma per gram, all exceeding values of lead content reported by previous authors for the human tooth, bones, blood and gingiva. 4) In view of the great amount of lead found in dental calculi, frequent scaling and oral prophylaxis should be recommended for the persons concerned. It was also concluded that determination of the lead content in dental calculi would make one of the important measures for the early detection and prevention of the systemic lead poisoning in these people.
