Abstract
Three-week-old male rats of the Wistar strain given standard formed food (MF formed food) were grouped as controls. Those given calcium-deficient food for three weeks and then standard formed food after experimental osteoporosis induced in the rats were grouped as the experimental group. Experimental periods were for 4 and 6 weeks and the effect of the food on osteoporosis was investigated.
The results were as follows:
1. Bone density of the alveolar bone showed significantly lower values for the experimental group than for the controls.
2. In comparison of relative Ca ratios (Ca/[Ca]c) and of P ratios (P/[P]c) on an X-ray microanalyzer, the controls showed higher values each week than the experimental group.
3. Compressive strength of the mandible in the experimental group decreased compared with the controls.
