| 中文摘要: |
| 本论文使用灰度法在数字化曲面体层片上比较牙周炎治疗前与基础治疗后2 个月牙槽骨密度的变化情况, 初步评价
了计算机灰度法对牙槽骨密度变化检测的敏感性。研究结果表明, 灰度法提示基础治疗后2 个月牙槽骨密度显著增加(P=0 .
003), 揭示了计算机灰度法对评价牙槽骨密度改变具有较高的灵敏度。 |
| 英文摘要: |
| To compare the changes of alveolar bone density before treat and after two months' initial therapy .This paper evaluates the
sensitivity of grey values for scaling the change of alveolar bone density .It has been shown by grey values that there is a distinct increase in alveolar
bone density after two months' initial therapy , which has revealed that the grey values are sensitive to evaluating the change of alveolar bone
density |
