1 Conclusions: Lactobacillus could promote the progression of dentinal caries for its adhering to dentin and producing lactic acid and causing dentin demineralization.

2 The lumina of the dentinal tubules were lined with a sheet-like lamina limitans which may play a role in the control of dentinal formation.

3 Methods:The mechanism of cryotherapy for dentinal hypersensitivity and the dose of cryosurgery were studied in guinea pigs.

4 Finally the opened area was closed by dentinal bridge. Conclusion: Polysaccharide and collagen protein biomembrane is effective in promoting the formation of reparative dentin.

5 Objective The dentinal tubules were patent after cavity preparation in the treatment of caries.

6 Objective: To determine the cariogenic bacteria in deep dentinal caries.

7 Objective To investigate the effect of a new desensitizer on the treatment of dentinal hypersensitivity.

8 Objective: To study how the depth and morphology of affected the dentinal stress distribution of the root of maxillary central incisor using three-dimensional-finite-element analysis.

9 Objective: To observe the mutual adsorption of hydroxyapatite(HA) particles and the sealing effect of HA microparticles on dentinal tubules.

10 AIM:To evaluate the effect of early Fluor Protector application after non-surgical periodontal treatment on root dentinal hypersensitivity.

11 Objective: To observe the relationship between the odontoblast process and the dentinal tubules.

12 In order to integrate the facts now know concerning the actual development of a dentinal caries,[] let us visualize some literatures.

13 In order to provide the scientific basis for the prevention and treatment on dentinal caries, the changes of the collagenous proteins in carious dentin was investigated.

14 Aim In order to provide the scientific basis for the prevention and treatment on dentinal caries, the changes of the collagenous proteins in carious dentin was investigated.

15 Characteristic:Xeno?III Single Step Self Etching Dental Adhesive avoids sensitivity by sealing dentinal tubules and eliminating problems of over drying and over- etching of dentin.

16 Although irrigants of group 3 could remove smear layer effectively, it resulted in moderate erosion of dentinal tubules.

17 In the cap stage, odontoblast, ameloblast and the adjacent dental papilla expressed the OSX protein strongly. OSX protein also existed in enamel-dentinal junction(), the new enamel and dentinal tubule.

18 The review presents the advances in researching at present and further researching direction on the common desensitizers of dentinal sensitivity.

19 CONCLUSION:Shanghai Anti-cavity toothpaste for Sensitive Teeth (Plus) has significant clinic efficacy on the treatment of dentinal hypersensitivity.

20 Results: Quartz fiber post would not change the inclination of dentinal stress distribution on the whole.

21 RESULT: The SEM pictures showed that the process formed a uniform layer covering and occluded with crystalloid substances in dentinal tubules.
