牙龈

Evaluated, in the four stages of one month, 3 months, 6 months and 12 months after restoration, their Plaque Index, Gingival Index, Gingival Bleeding Index, Probing Depth and X-ray bone absorption. Subgingival plaque samples were isolated and cultured by the selective medium of black-pigment bacteria, F. nucleatum, Actinomyces viscosus and anaerobium.

临床选取32名种植患者的44枚种植体，记录了修复后1个月，修复后3个月，修复后6个月，修复后12个月四个时段，入选种植牙的菌斑指数，牙龈指数，牙龈出血指数，探诊深度；采用产黑菌、放线菌、具核梭杆菌及厌氧菌的选择性培养基对龈下菌斑标本进行了分离培养。

Three cross-sections were made through crown and gingiva of the model tooth. Curve functions of axial buccal crown and gingiva contour of each section were acquired by means of curve fitting, and the angle of emergence pofile was calculated, which represents the degree of undercut.

以下颌第二前磨牙为研究对象，在牙列模型上通过牙冠部、牙龈作3个纵断面，用曲线拟和的方法得到每个断面的牙齿轴面外形及相应牙龈外形的曲线方程，以此分析两者之间的关系并计算牙冠起始外形角度，即倒凹程度的大小。

To maintain healthy teeth and gums it is important that bristles contact both the tooth surface and the gumline.

为了保持健康的牙齿和牙龈重要的是，无论是刷毛接触牙齿表面和牙龈线。

A total of one hundred fifty three healthy male and female adults were entered into a six month,doubleblind clinical study designed to evaluate the effect of a dentifrice containing 0.3% triclosan and 2.0% PVM/MA copolymer in a 0.243% sodium fluoride/silica base, relative to a 0.243% sodium fluoride silica base control dentifrice on supragingival plaque accumulation and gingivitis.

本研究的目的是证实含0.3％三氯羟苯醚，2.0％PVM／MA及0.243％氟化钠以二氧化硅磨料牙膏在减少菌斑积聚和牙龈炎形成方面对中国成年人群的效果。153名健康男女分为实验组及对照组，用双盲法评价6月后临床效果。采用纳入和排除的评价标准后进行了基线检查，实验对象每日使用分配的牙膏和软毛牙刷早晚刷牙一次，3个月和6个月再次检查。检查结果表明，使用含有三氯羟苯醚－共聚体牙膏组与使用不含该成分的对照组相比，实验对象的牙菌斑、牙龈炎指数分别减少16.1％及24.3％，均有统计学显著性意义（P＜0.001）。

Great majority tooth week the burning sufferer all accompanies with the gum atrophies of symptom, the survey discovers, in the crowd over 45 years of age, above 90% exists the gum of different degree to atrophy a phenomenon, while the gum atrophy, also always drive mouth cavity medical science the field see to deteriorate a phenomenon for the physiology that can not converse.

绝大多数牙周炎患者都伴随着牙龈萎缩的症状，调查发现，在45岁以上的人群，90％以上存在不同程度的牙龈萎缩现象，而牙龈萎缩，也一向被口腔医学界视为不可逆转的生理退化现象（对于不可逆转的观点，显得已经有点过时了，对于这个问题，将在以后的文章部分专门说明）。

The reason that the gum atrophies, though knows to is a vitamin to lack, but usually atrophies a sufferer in the gum body up, hardly discover the whole body comprehensive symptom that the vitamin lacks, at clinical up, pass a great deal of food vitamin, cure the effect that the gum atrophies also poor.

牙龈萎缩的原因，尽管知道是维生素缺乏，但是通常在牙龈萎缩患者身上，很少发现维生素缺乏的全身综合症状，在临床上，通过大量服食维生素，来治疗牙龈萎缩的效果也不佳。

The width of keratinized gingiva was measured at every canine according to the method explained by [10] where every single measurement was made from the free gingival edge to the muco-gingival conjunction on the buccal surface of the canine.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
