Abstract

尿路結石と歯石には, 成分や発現年齢においていくつかの共通点が認められる。本研究では, 尿路結石を有する人の歯石沈着程度を明らかにするために, 尿路結石患者40名および結石の既往のない対照被験者57名の口腔内診査を行い, 歯石沈着指数を調べることによって, 両群を比較検討した。さらに, 尿路結石患者の尿中成分と歯石沈着指数の相関についても検索した。-歯石沈着指数は, OHI指数に基づいた前歯および大臼歯6部位を検査するCI-S指数を採用した。結石群のCI-Sは1.10±0.09 (平均値±標準偏差値) であり, 対照群の0.37±0.05と比べ3.1倍と有意に高い値を示した。また, 下顎前歯舌側部に限定して指数を調べた場合でも, 結石群1.63±0.15, 対照群0.60±0.11と, 2.7倍の有意な高値を示した。この現象は男女の性別にかかわらず認められた。一・方, 尿中Ca量およびPi量とCI-Sとの相関を調べたところ, これらの問には何ら相関関係は認められなかった。以上のように, 尿路結石患者は, 結石をもたない人に比べて, 歯石沈着量が多いことが明らかとなり, 尿路結石患者の尿中Ca量およびPi量と歯石の沈着程度には関連がなかった。今回の調査結果は, 尿路結石および歯石形成機構には何らかめ密接な関連があることを裏付ける興味深い結果であると言うことができる。

There are some common features between urinary stones and dental calculus in terms of contents and the age-related incidence. In this study, we investigated dental calculus condition in patients suffering from urinary stones in order to determine whether or not these patients tend to have any more dental calculus than persons who have never had urinary stones. The subjects were 40 patients (stone group, mean 53 years old) and 57 controls (control group, mean 47 years old). None of the subjects had had a scaling treatment within 6 months. CI-S was applied for the dental calculus index using 6 anterior and posterior teeth, as previously reported. The examination revealed that CIS in the stone group was significantly higher than in the control group, showing 1.10±0.09 and 0.37±0.05, respectively. A three-times higher index was also observed when 6 mandibular anterior teeth were examined (1.63±0.15 vs. 0.60±0.11). Correlations between calcium- or phosphor-contents in urine and CI-S were determined, but there were no correlations between the urinary contents and CI-S, indicating that the incidence of dental calculus does not relate to urinary calcium and phosphor. These findings suggest that there may be a close relationship between urinary stones and dental calculus formations.
