牙石是龈下各种牙周有害病菌滋生比不可少的"载体"，由于牙龈萎缩，而令厌氧菌在龈下得以滋生、扩散，长期侵袭着牙龈和牙周组织的健康；同时如前面所说的由于牙龈的营养不良，此消彼长之下，进而导致成年人口腔抵抗疾病侵害的能力，随着年龄增长而大幅衰退的结果，从而引发各种牙龈炎、牙周炎、牙髓炎症状。

Methods 184patients（age18～60）with184infected permanent teeth were randomly divided into two groups.The experimental group was filled with the VITAPEX paste plus gutta percha.

The results indicated that the histopathological changes of periodontum occured earlier and more seriously in diabetic rat. This demonstrates the promote effect of diabetes on the occurence and progression of the experimental periodontitis.

而糖尿病大鼠在同样的实验条件下，3周便出现类似的损害，9周时，出现深层组织的炎细胞浸润、牙槽骨吸收和深牙周袋形成，表明糖尿病具有缩短引起实验性牙周炎的时间和加重牙周组织破坏的作用，认为在建立大鼠实验性牙周炎模型的过程中引入糖尿病这一因素是一值得推荐的措施。

结果：Smad1，4，5在正常和龋坏牙髓的成牙本质细胞层呈强阳性表达，在下方的富细胞区及牙髓中心部位为阳性或弱阳性表达，炎症牙髓浸润的炎细胞中Smad1，4，5呈强阳性表达。

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。
