本文利用邻苯三酚改良法测定４７名健康人牙髓组织活性。结果表明，人牙髓组织ＳＯＤ活性与年龄有关，老年人（＞６０岁）ＳＯＤ活性显著低于青少年人（＜３０岁）和中年人（３０～６０岁）。并且人牙髓组织ＳＯＤ活性无性别差异。此外，长期吸烟喝酒者牙髓组织ＳＯＤ活性低于对照组，但无显著差异。
In this paper, pyrogallol modified method was used to determine the activity of pulp in 47 healthy people. The results showed that the activity of SOD in human dental pulp tissue was related to age. The activity of SOD in the elderly (> 60 years old) was significantly lower than that in the adolescent (<30 years old) and middle age (30-60 years old). And there is no gender difference in SOD activity of human dental pulp tissue. In addition, long-term smoking drinkers dental pulp SOD activity was lower than the control group, but no significant difference.
