女性正畸患者月经周期中最佳加力时机的初步研究
目的:通过在女性月经周期中的不同时期对正畸牙加力,研究龈沟液内雌激素(E2)、骨钙素(OCN)、核因子κB受体活化因子配体(RANKL)、骨保护素(OPG)的时效性表达,从而为临床选择最佳加力时机提供理论依据。方法选取18~28周岁双侧对称拔除第一恒前磨牙青年女性恒牙患者12人。随机选取其中6人为月经期加力组,6人为排卵期加力组,于右侧尖牙单侧使用镍钛拉簧施加1.5N正畸力使之远中移动,对侧尖牙不做处理。使用牙周滤纸分别于加力前,加力后15、30、45d取右侧尖牙远中(压力侧)龈沟液样本。使用化学发光法测定龈沟液中E2、OCN的活性水平。使用酶联免疫法检测龈沟液中RANKL及OPG的活性水平。...

Summary: | 目的:通过在女性月经周期中的不同时期对正畸牙加力,研究龈沟液内雌激素(E2)、骨钙素(OCN)、核因子κB受体活化因子配体(RANKL)、骨保护素(OPG)的时效性表达,从而为临床选择最佳加力时机提供理论依据。方法选取18~28周岁双侧对称拔除第一恒前磨牙青年女性恒牙患者12人。随机选取其中6人为月经期加力组,6人为排卵期加力组,于右侧尖牙单侧使用镍钛拉簧施加1.5N正畸力使之远中移动,对侧尖牙不做处理。使用牙周滤纸分别于加力前,加力后15、30、45d取右侧尖牙远中(压力侧)龈沟液样本。使用化学发光法测定龈沟液中E2、OCN的活性水平。使用酶联免疫法检测龈沟液中RANKL及OPG的活性水平。结果排卵期加力组龈沟液E2和OCN水平高于月经期加力组(P〈0.05)。月经期加力组与排卵期加力组中RANKL水平与OPG水平及RANKL/OPG比值均未见明显差异(P〉0.05)。结论女性正畸拔牙患者于雌激素水平较高的排卵期施加正畸力,骨保护因子E2、OCN表达增强,不利于牙槽骨改建。而于月经期加力,上述因子表达减弱,可能有助于牙齿快速移动。 |

Methods Twelve women (aged 18 years to 28 years) with extracted first premolars had been selected. Six women in the group were randomly selected as the menstrual period group, whereas the remaining six were assigned to the ovulation period group. Right canines were retracted with 1.5 N NiTi close c |
