乳歯列の口腔衛生状態-パイロット調査

Oral health status for primary dentition - A pilot study.

抄録

はじめに:

小児専用の口腔衛生指標（OHI），巧緻性指標，白点病変（WSL）の発生率を含む口腔健康状態を策定することで，検者は小児の現在の口腔健康状態を容易に評価することができ，予防戦略の立案に役立てることができる．この指標には、過去のう蝕経験、現在の口腔衛生状態、将来のう蝕予測が含まれており、小児の口腔衛生状態を包括的かつ迅速に評価することができる。

Introduction: Formulating an oral health status which will include oral hygiene index (OHI) exclusively for children, deft index, and the incidence of white spot lesions (WSL) will make it easier for the examiner to assess the current oral health status of a child and help in planning preventive strategies. This index will provide a comprehensive yet quick way to assess the oral health status of children as it includes past caries experience, present oral hygiene status, and future prediction of caries.

材料と方法:

本研究では，3～5歳の乳歯列を有する200名の小児（男性100名，女性100名）を対象とした．OHI，記録された歯と歯節のインデックス，デフトインデックス，WSLs分類を全児童に記録した．受信者動作特性（ROC）曲線を用いて，小児のOHIの記録精度を指標歯牙単位とセグメント単位で評価した．

Materials and Methods: Two hundred children (100 male, 100 female) aged 3-5 years (primary dentition) were included in this study. OHI, recorded index tooth wise and segment wise, deft index, and the WSLs classification were recorded in all the children. Receiver operating characteristics (ROC) curve was used to evaluate the accuracy of recording OHI in children index tooth wise and segment wise.

結果:

200名の被験者を対象に3つの指標を記録し，受信者動作特性曲線下面積から，乳歯列のOHIは歯牙単位またはセグメント単位で記録可能であることがわかった．乳歯列の指標となる歯は，唇側表面が54，61，64，舌側表面が82，75，85であった．

Results: All the three indices were recorded for the 200 subjects, and based on the area under the curve of receiver operating characteristics, it was found that the OHI for primary dentition can be recorded tooth wise or segment wise. Index teeth chosen for primary dentition were labial surfaces of 54, 61, and 64, lingual surfaces of 82, 75, and 85.

まとめ:

過去のう蝕の経験、現在の衛生状態、将来のう蝕の予測を含む、健全な指標である。この累積指標は、疫学研究に広く利用することができ、公立学校の歯科保健プログラムにおける評価を迅速に行うことができる。

Conclusion: It includes the past caries experience, present hygiene status, and the future prediction of caries, making it a wholesome index. This cumulative index can be widely used in studies of epidemiology and ensure quicker evaluation during dental health programs in public school systems.
