ABSTRACT
Objective To evaluate the effect of repair and chewing function recovery of fiber post and casting metal post in the restoration of large area tooth defect .Methods 100 cases of patients with large area tooth defect from August 2011 to June 2013 in our hospital were chosen to research , and were divided into the control group and the experimental group.The control group were treated with casting metal post , and the experimental group were trea -ted with fiber post.The effect of repair, bite force, chewing function and inflammatory factor levels in gingival crevic -ular between two group were compared .Results Chewing efficiency and bite force of experimental group were higher than the control group, and the difference had significant significance (p <0.05).Off, loose, discoloration and frac-ture repair effect decline rate of experimental were lower than the control group , and IL -6 and IL -8 of the experi-mental group were lower than the control group .The difference were significant(p <0.05).Conclusion Fiber post could effectively improve treatment effects in the restoration of large area tooth defect , chewing functions, and the effect of repair could be greatly improved .
ABSTRACT
In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin B2 intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.

Occlusion is a term for the contact relation between upper and lower dentitions.It is a three dimensional relationship.The vertical occlusal contact relation includes convex-to-concave contact relation between structures on occlusal surfaces of the upper and lower teeth at status of intercuspal occlusion,as well as that during protrusion,retrusion and lateral excursive movements.Occluding function depends on the contact condition of occlusion.However,the morphological criterion of the vertical occlusal contact is still lacking.Widely practical criterion for dental treatment includes only mesial-distal relation,such as one-to-two teeth contact relation between upper and low dentitions,and labial/buccal-lingual relation,such as over jet and over bite.To establish a vertical occlusal contact criterion that meets the need for individual occlusal treatment is one of the main subjects in Occlusion field.
