ネパール中央部カスキ郡・デタール村住民の生活習慣を含めた健康調査、歯科検診、歯周病原細菌に関して 調査し、以下の結果を得た。 1.う蝕罹患状況・未処置かつ重症化したう蝕歯をもつ者が多い。一人平均う蝕本数が加齢とともに増加していた。う蝕処置 をしている者が少なく、抜去している歯が多かった。 2.歯周疾患罹患状況・歯周組織検査ではCPI:0(健全)の者はどの年代でも少なく、加齢に伴い重症化していた。・喫煙者と非喫煙者の比較では、CPI値が喫煙者の方が高く、喫煙と歯周病の関連性が示唆された。・ブラッシングの回数は2回者が最も多く、回数が多い者ほどCPI値は低値を示した。 3.唾液潜血反応検査と歯周病原細菌検査・唾液潜血反応陽性者は95%だった。また、ブラッシング時出血自覚症状の有無と唾液潜血反応の結果は、ほぼ一致した。・歯肉に炎症ある者にPorphyromonas gingivalis ( Pg 菌)に対する血漿抗体価陽性の傾向が認められ、唾液潜血反応結果では潜血反応陽性者の Pg 菌に対する血漿抗体価は陰性の傾向が認められた。このことから、この地域の歯周病罹患率ならびにう蝕罹患率は高く、重症化していることが示唆された。A health check including an interview about life habits, dental checkup and investigation of periodontopathic bacteria of periodontal disease among the residents of Dhital village, Kaski District,Nepal was conducted. The results are as follows: 1.Prevalence of dental caries・There were many residents who had serious tooth decay resulting from lerving it untreated.The average number of tooth decay has increased with aging.There were not many people who treated their tooth decay,and many of their teeth were extracted. 2.Prevalence of periodontal disease・The survey of periodontal tissue showed that there were only a few people with CPI:0(healthy periodontal tissue)in every generation,and prevalence rate was rising with aging.・The comparison between smokers and non-smokers showed that the average CPI values of smokers were higher than that of non-smokers, and it suggested a correlation between smoking and progression of periodontal disease.・There were a large number of people who brushed their teeth twice a day. The more examination they brushed their teeth, the lower the value of average CPI became. 3.Salivary occult blood test and periodontopathic bacteria test・Positive persons of occdlt blood examination were 95%. The presence of the subjective symptom with respect to bleeding during brushing teeth almost agreed with the result of the salivary occult blood test.・A positive trend for plasma antibody value against Porphyromonas gingivalis was found among the people with gingival inflammation. As a result of reaction against salivary occult blood, there was a negative trend for the plasma antibody value against Porphyromonas gingivalis . From there results,it was suggested that among people living in thie district, prevalence of both periodontal disease and tooth decay were high,and their conditions were serious
