本文用大白鼠研究牙齿缺失对衰老的影响。用实验分组法将动物分成两组(实验组和对照组),分别将实验组大白鼠牙齿部分拔除,然后进行三年的对照观察,结果发现两组有明显的差异性。与此同时,将正常年龄组中60岁的正常人也通过实验分组法分成两组,选出牙齿缺失者与未缺失者进行为期三年的观察和比较,结果发现两组有很大的差别。衰老均与牙齿缺失有关。
In this paper, the effects of tooth loss on aging were studied in rats. The animals were divided into two groups (experimental group and control group) by experimental grouping method. The rats in the experimental group were partially removed and then observed for three years. The results showed that there were significant differences between the two groups. At the same time, the normal age group of 60-year-old normal subjects were also divided into two groups by experimental method, selected teeth missing and non-deleted for a period of three years of observation and comparison, the results found that there is a big difference between the two groups . Senescence and tooth loss are related.
