STATEMENT OF PROBLEM The modern dentistry approach is moving toward preventive dentistry, an approach that has decreased the prevalence of caries within the past decades. Since some reports imply that dentists are not knowledgeable enough in this issue. PURPOSE This study aimed to evaluate the attitude and awareness of future dental graduates toward preventive dentistry regarding gender and e...

AIM This was to determine the prevalence of primary tooth fluorosis in the dentitions of 5-year-old schoolchildren. A subsidiary aim was to investigate whether an association existed between the presence of primary tooth fluorosis, fluoridation status, infant feeding practices or the oral hygiene practices of the child. STUDY DESIGN A cross-sectional and stratified by fluoridation status stud...

OBJECTIVES To compare prevalence and incidence of caries between fluoridation-ended and still-fluoridated communities in British Columbia, Canada, from a baseline survey and after three years. METHODS At the baseline (1993/4 academic year) and follow-up (1996/7) surveys, children were examined at their schools. Data were collected on snacking, oral hygiene, exposure to fluoride technologies, ...

Fluoridation of water supplies has proven to be an effective preventive measure for dental caries. Many developing countries in the Americas have multiple water systems and economies that do not permit the viable application of this approach. Some of the highest dental caries prevalence in the world was evident in the Americas. Fluoridated salt was considered as a potential solution on account ...

The widespread availability of fluoride from many sources is accepted as a major reason for the caries decline among children in developed countries. There is still controversy, however, about its principal mode of action. This article reviews the evidence on fluoride's preeruptive and posteruptive effects, and suggests reasons for its continuing role in the caries decline. Early fluoridation s...

The decline in dental caries prevalence and incidence in developed countries over the last two decades is considered to be largely due to the widespread use of fluoride. Simultaneously, with the decline in caries, an increase in the prevalence of dental fluorosis has been noticed. The increase is in the mild and very mild forms of fluorosis, and is proportionally greater in non-fluoridated area...

BACKGROUND The quantification of fluorosis using fluorescence imaging (QLF) hardware and stain analysis software has been demonstrated in selected populations with good correlation between fluorescent image metrics and TF Index scores from photographs. The aim of this study was to evaluate the ability of QLF to quantify fluorosis in a population of subjects (aged 11-13) participating in an epid...

概要:歯 周疾患 の蔓延は齲蝕 とともに著 しい 高率を示 してい る、この疾患の原 因は 複雑であるが, 日常の習慣でこれを予防す る場合,重 要 視 しなければな らないのは,歯 ブラシと歯磨 を用い て歯口清 掃 を適正に行 うことである.こ こにおいて,歯 牙付着物除去 と歯肉疾患 の予防や治療 に効果あ ると思 われ る3薬 剤 を歯磨 中に添加 して,そ の薬剤 の効果について比較検討 した。研究対象 および研究方法 と しては,健 康 な る成 人女子 を選び,そ の中の21名 にアラ ン トイ ンを,24名 にイプシ ロンを,ま た25 名 にジ ヒトロコレステ リンをそれ ぞれ添加 した歯磨 を28日 間連続使用せ しめた。そ して,使 用直前 と 使用後7日 間お きに5回,歯 周組織 の健康診断 を行 い,自 ・他覚的症状 を観察 した。その結果,歯 牙 付着物...
