您要查找的是不是：
- outer enamel surface [医] 釉质外表面
- It was expressed focally in the oral epithelium, dental lamina, outer enamel epithelium, stratum intermedium and stellate reticulum at cap and bell stages. 结果 :COX - 2在牙胚发育期间存在特异的时空分布模式 ,其阳性表达主要在牙胚发育帽状期、钟状期的口腔上皮、牙板上皮、外釉、中间层和星网状层。
- Demineralization continues.Enamel starts to break down.Once the enamel surface is broken, the tooth can no longer repair itself. 去矿化继续，釉质开始崩解，一旦釉质受到破坏，牙齿将不可自行修复。
- Objective To study the influence of various active groups grafted on the enamel surface by means of self assembly on enamel biomineralization. 目的通过自组装技术在牙釉质表面接枝不同活性基团,进而研究不同基团对牙釉质表面生物矿化的影响,为深入探讨牙釉质的再矿化提供基础。
- And the calcium in the vinegar were analyzed by EL 312e microplate.The enamel surface microhardness was measured by a microhardness tester. 采用维氏显微硬度仪测定经食醋涂擦后乳牙牙釉质表面显微硬度的变化。
- In bell stage(E19),the positive staining was detected in both inner and outer enamel epithelium,but the inner was less than that of the outer and less positive staining was also found in the cells of stratum intermedium and stellate reticulum. 钟状期(胚胎19d),内、外釉上皮阳性表达,但内釉上皮较外釉上皮表达弱,中间层及星网状层细胞弱阳性表达;
- CONCLUTION: Toothpastes containing polyphosphate can increase wetting of enamel surface, which can improve consumer's tooth-brushing experience. 结论：含有多聚磷酸钠的佳洁士皓爽白牙膏在提高釉质表面润湿性方面优于一般防蛀牙膏，能明显提高刷牙者牙齿滑爽的程度。
- Results show that outer enamel of corona dentis has an excellent tribological resistance, and mixed layer between enamel and dentine zone has better abrasive resistance than dentine zone. 结果表明牙冠外层的釉质具有优良的摩擦学特性,牙釉质/牙本质交界面的耐磨性稍逊于外层釉质,但明显高于牙本质。
- Conclusion: BEYOND cold light bleaching can immediately induce demineralization of dental enamel surface and changes of dentin morphology. 结论：BEYOND冷光漂白可使牙釉质表层脱矿，并能透入到牙本质层使其微结构发生轻微改变。
- The proposal is used but as graininess as water compound cleaner comes cleanness massages bath crock, avoid to use the cleaner that is used at ceramic tile or enamel surface. 建议使用可与水混合的粒状清洁剂来清洁按摩浴缸，避免使用用于瓷砖或搪瓷表面的清洁剂。
- Thisdifference between the Mutans group and Sobrinus group was signifcant stayistically. Effect of measurement of hardness in enamel surface showed clea in the Mutuans group decreased by 35%and sobinus group by45%. 结果 变形链球菌和远缘链球菌均可使牙釉质表面显微硬度下降 ,下降率分别为 35%25和 4 5%25 ,且远缘链球菌组随时间下降高于变形链球菌。
- When installing the holding-down clip, you should tighten is smmetrily and orderly, put forth your steength evenly to avoid strong local stress, which will deform flange and injure enamel surface. 安装卡予时，要求对称按顺序拧紧，用力均匀以免局部应力适大，使法兰变形而破坏瓷面。
- The hard outer portion or surface area of bread. 面包皮面包的表面区域的硬皮
- Milk proteins could adsorb to tooth enamel surfaces selectively and form an acquired protein pellicle, which is closely related to tooth demineralization and remineralization. 牛奶可以在釉质表面形成一层获得性蛋白膜,与牙表面的脱矿和再矿化密切相关。
- Dust the repair to prevent adhesion to outer cover. 清整修补处以防与外胎粘连。
- AIM: To evaluate the effect of dentifrice (Crest Whitening-containing polyphosphate, and Crest anti-cavity, P&G Co.) on wetting of enamel surfaces in vitro by measuring contact angles. 摘要目的：研究比较佳洁士皓爽白牙膏、防蛀牙膏对离体牙釉质表面润湿性的影响。
- An outer coat of glaze on a piece of pottery. 外层釉陶器釉面上的第二层釉
- The outer walls of the building were painted blue. 这座建筑的外墙被漆成了蓝色。
- The pots are made with blue enamel. 这些锅上有蓝色的搪瓷。
- Some of the enamel on this pan is chipped off. 这平底锅上的搪瓷有些已脱落。
