cementum

1 In the years sows are pregnant, their teeth will grow a thick cementum layer from gaining so much weight.

2 In a similar vein, a substance called cementum protects your teeth’s roots, which contain the pulpy center that holds blood vessels and nerves.

3 In the summer, when food is plentiful and stress is minimal, growth happens more quickly and a lighter layer of cementum forms.

4 These findings may contribute to the development of a periodontal treatment that includes cementum regeneration.

这些结果可以有助于牙周治疗的发展，包括牙骨质的再生。

5 Looking at the teeth using polarised light microscopy, the team found the interaction of the cementum with light was not the same throughout the tissue.

6 The researchers are also working with high-resolution CT scans to develop a non-destructive method of studying cementum.

7 A typical reptile has only two kinds of dental tissues—hard enamel and soft dentine—and a typical mammal has four, including cementum and a second kind of dentine.

8 Another way to estimate age is to use a microscope to count the yearly additions of a mineralized tissue called cementum on teeth.

9 Methods Cell culture technique in vitro had been used to study the growth condition of MC3T3-E1 osteoblast line on the surface of cementum treated with various methods.

10 Dentin matrix protein (DMP) -1 is an acidic non-collagenous protein that is necessary for the proper biomineralization of bone, cartilage, cementum, dentin and enamel.

11 "Even though the periodontal tissue is composed of gingiva, periodontal ligament, alveolar bone, and cementum, analyses are usually performed exclusively on gingival samples due to technical and quantitative limitations," remarks lead author Mr. Anhao Liu.

12 Root conditioning by minocycline-HCl could improve PDLC attachment and proliferation on root cementum surface affected by periodontitis.

13 The ligament, a soft tissue that is about 0.2 millimeters wide (about the diameter of four hairs), attaches the cementum of the root on one end to the bone of the jaw on the other end.

14 Meanwhile, Matson’s boasts an extremely high level of accuracy in its cementum annuli analysis work.

15 An annulus, or dark ring, is formed each winter between the cementum formed in spring and summer growth periods.

16 As a result Cerrito and colleagues looked at a different tissue, cementum, that grows throughout an individual’s life.

17 They will target cementum in their next attempt.

18 Dr Nweeia and the team's analysis revealed that the outer cementum layer of the tusk is porous and the inner dentin layer has microscopic tubes that channel in towards the centre.

19 Objective:To analyze the N-terminal amino acid sequence of bovine cementum attachment protein(CAP), which lay a theoretical foundation for cloning and expression of the CAP.

目的：对牛牙骨质附着蛋白进行N末端氨基酸序列分析，为牙骨质附着蛋白的克隆表达提供一定的理论依据。

20 Methods BMSCs were co-cultured with cementum slices and femora slices in vitro, to detect with light microscope at 7 day and 28 day, and to determine ALP activity.

方法将骨髓基质细胞与牙骨质片和股骨片在体外共同培养，分别在第7天、第28天进行光镜观察及碱性磷酸酶的测定。
