摘要
〕目的：了解锌在正畸牙周组织改建中的作用。方法：利用原子吸收分光光度法（ＡＡＳ）测定在不同时间内，兔牙加力侧与自体非加力侧牙周组织及正畸矫治前后血清锌含量。结果：①在实验的第７ｄ，加力侧牙周组织内锌含量增加显著（Ｐ＜０．０５）；②血清锌在正畸加力后第３天下降明显，第５天基本恢复正常。结论：牙周组织中锌含量变化与牙齿移动过程中组织反应程度有关，锌参与了正畸牙周组织改建活动。
Objective: To observe the changes of zinc level in periodontal tissue and serum during orthodontic treatment in rabbits. Mettods: Experimental orthodontic treatment was given in rabbits and zinc concentration in the periodontal tissue and sersum.was measuse with atomic absorption spectrophotometry(AAS). Results: On day 7 zinc content in periodontium was 58.92±10.76μg/g at the forced side and 44.34±7.66μg/g at the non forced side( P <0.05)。 On day 3 zinc concentration in serum was 1.93±0.22μg/ml in the treated group and 2.28±0.28μg/ml in the control( P <0.05). On day 5 zinc levels in serum in the treated and contrtol groups were 2.24±0.26μg/ml and 2.28±0.28μg/ml respectively( P >0.05). Conclusion: The change of zinc content in periodontium and serum is related to the response of tissue in orthodontic tooth movement. Zinc is involved in periodontium remodeling.
