FAQ

洗牙到底在洗什么？跟自己刷牙差在哪？
**差在对象的物理状态：自己刷牙处理的是未矿化的生物膜，专业层处理的是已经钙化、附着力被强化过的牙结石 [F62][F63]。** 牙结石的形成是一个从未矿化生物膜开始、逐渐钙化的动态过程，矿化过程本身会强化生物膜对牙面的附着 [F62]；而从临床角度看，牙结石始终带着一层活的、未矿化的生物膜 [F63]。文献对「常规洗牙抛光」的定义，是对牙冠与牙根表面进行牙结石清除或抛光、或两者兼具，以移除牙菌斑、牙结石、残屑与染色等局部刺激因子 [F35]。实际需要处理到什么程度，须由牙医师检查后评估。
歯石除去（スケーリング）は結局のところ何を落としているのですか？ 自分で磨くのと何が違うのですか？ — **違うのは対象の物理的な状態です：自分で磨くときに扱っているのは未石灰化のバイオフィルムであり、専門的レイヤーが扱うのはすでに石灰化し、付着力が強められた歯石です [F62][F63]。** 歯石の形成は未石灰化のバイオフィルムから始まり、やがて石灰化していく動的な過程であり、石灰化の過程そのものがバイオフィルムの歯面への付着を強めます [F62]；そして臨床的な観点から見ると、歯石は常に生きた未石灰化のバイオフィルムを抱えています [F63]。文献の「ルーティンのスケーリングとポリッシング」の定義は、歯冠と歯根の表面に対して歯石除去または研磨、あるいはその両方を行い、プラーク、歯石、残渣、着色といった局所の刺激因子を除去することです [F35]。実際にどの程度まで処置する必要があるかは、歯科医師の検査による評価が必要です。
What is a scaling actually removing? How is it different from brushing my own teeth? — **The difference lies in the physical state of what is being dealt with: brushing at home handles nonmineralized biofilm, while the professional layer handles calculus that has already calcified and whose attachment has been strengthened [F62][F63].** The development of dental calculus is a dynamic process that starts with a nonmineralized biofilm and gradually calcifies, and the process of mineralization itself strengthens the attachment of the biofilm to the tooth surface [F62]; from a clinical point of view, dental calculus always harbours a living, nonmineralized biofilm [F63]. The literature defines a routine scale and polish as scaling or polishing, or both, of the crown and root surfaces of teeth, in order to remove local irritational factors such as plaque, calculus, debris and staining [F35]. How far treatment actually needs to go must be assessed by a dentist after examination.
「每天两次、每次两分钟」这个数字是怎么来的？
**是三个国际来源一致的建议，但它的证据性质需要一起知道 [F5][F13][F24]。** 世界卫生组织建议每日两次使用含氟牙膏（1000 至 1500 ppm）刷牙 [F5]；美国牙医学会的一般建议是每天两次、含氟牙膏、两分钟 [F13]；欧洲牙周病学会的共识报告支持所有人每日两次、每次至少 2 分钟、使用含氟牙膏 [F24]。关于「两分钟」，现有系统综述发现两分钟相较一分钟与较大幅度的牙菌斑减少有关 [F16]，但这类资料依赖的是牙菌斑指数这个替代指标，不是龋齿或牙龈炎的直接测量 [F17]。另外要注意：研究中被评估的是「使用含氟牙膏刷牙的频率」，不是单独的刷牙动作 [F15]。
「1 日 2 回、毎回 2 分間」というこの数字はどこから来たのですか？ — **三つの国際的な出典が一致している推奨ですが、そのエビデンスの性質も一緒に知っておく必要があります [F5][F13][F24]。** 世界保健機関はフッ化物配合歯磨剤（1000 から 1500 ppm）による 1 日 2 回のブラッシングを推奨しています [F5]；米国歯科医師会の一般的な推奨は 1 日 2 回、フッ化物配合歯磨剤、2 分間です [F13]；欧州歯周病学会の合意報告は、すべての人が 1 日 2 回、毎回少なくとも 2 分間、フッ化物配合歯磨剤を用いることを支持しています [F24]。「2 分間」については、既存のシステマティックレビューが 2 分間は 1 分間と比較してより大きなプラークの減少と関連していることを見いだしていますが [F16]、この種のデータが依拠しているのはプラーク指数という代替指標であって、う蝕や歯肉炎の直接的な測定ではありません [F17]。もう一つ注意すべきなのは、研究で評価されたのは「フッ化物配合歯磨剤を用いたブラッシングの頻度」であって、ブラッシングという行為単独ではないということです [F15]。
Where does the “twice a day, two minutes each time” figure come from? — **It is a recommendation on which three international sources agree, but the nature of its evidence needs to be known alongside it [F5][F13][F24].** The World Health Organization recommends twice-daily tooth brushing with fluoride-containing toothpaste (1000 to 1500 ppm) [F5]; the American Dental Association's general recommendation is twice a day, with a fluoride toothpaste, for two minutes [F13]; and the consensus report of the European Federation of Periodontology supports all people brushing twice a day for at least 2 minutes with fluoridated dentifrice [F24]. On the two minutes: the available systematic reviews found that two minutes was associated with a greater reduction in plaque than one minute [F16], but the data of that kind rely on plaque indices, a surrogate measure rather than a direct measure of caries or gingivitis [F17]. One further point: what was evaluated in the studies was the frequency of tooth-brushing with a fluoride toothpaste, not the act of brushing on its own [F15].
牙线和牙间刷，该用哪一个？
**证据方向指向牙间刷，但选择还取决于牙缝条件与你会不会持续做 [F25][F44][F18]。** Cochrane 纳入 35 篇随机对照试验、3,929 位成人的回顾记载，牙间刷可能比牙线更有效 [F44]；欧洲牙周病学会的共识报告写明牙间刷是牙邻面牙菌斑清除时所选用的器械（原文 device of choice），牙线则用于牙间刷无法无创通过邻面区的情形 [F25]。但同一份 Cochrane 回顾自评证据为低至极低确定性、效应量可能不具临床重要性 [F46]，且没有试验评估邻面龋齿 [F48]。执行面上，牙线是技术敏感的介入 [F18]，而对任何特定病人而言，适合的方法会是他们愿意规律执行的那一个 [F18]。牙缝条件属临床检查项目，须由牙医师评估。
デンタルフロスと歯間ブラシ、どちらを使うべきですか？ — **エビデンスの方向は歯間ブラシを指していますが、選択は歯と歯の間の条件と、あなたが続けられるかどうかにも左右されます [F25][F44][F18]。** Cochrane が 35 篇のランダム化比較試験、3,929 人の成人を組み入れたレビューは、歯間ブラシがデンタルフロスより効果的である可能性があると記録しています [F44]；欧州歯周病学会の合意報告は、歯間ブラシが隣接面のプラーク除去において選択される器具である（原文 device of choice）と明記し、デンタルフロスは歯間ブラシが隣接面を無傷で通過できない場合に用いるとしています [F25]。しかし同じ Cochrane レビューは自己評価としてエビデンスを低いから非常に低い確実性とし、効果量は臨床的に重要でない可能性があるとしており [F46]、また隣接面のう蝕を評価した試験は一つもありません [F48]。実行の面では、フロッシングは技術に敏感な介入であり [F18]、ある特定の患者にとって最も適した方法は、その人が規則的に実行するであろう方法です [F18]。歯と歯の間の条件は臨床検査の項目であり、歯科医師の評価が必要です。
Floss or interdental brush — which should I use? — **The evidence points towards interdental brushes, but the choice also depends on the condition of your interdental spaces and on whether you will keep it up [F25][F44][F18].** The Cochrane review of 35 randomised controlled trials with 3,929 adults records that interdental brushes may be more effective than floss [F44]; the consensus report of the European Federation of Periodontology states that interdental brushes are the device of choice for interproximal plaque removal, and that floss is for sites where an interdental brush will not pass through the interproximal area without trauma [F25]. But the same Cochrane review judges its own evidence to be of low to very low certainty and notes that the effect sizes may not be clinically important [F46], and no trials assessed interproximal caries [F48]. On the doing of it, flossing is a technique-sensitive intervention [F18], and for any given patient the method that works will be the one that they will regularly perform [F18]. The condition of your interdental spaces is a matter for clinical examination and must be assessed by a dentist.
