【摘要】：目的：探讨青年女性患者在月经期与排卵期加力对正畸牙移动影响,观测两组加力后疼痛程度是否具有统计学差异,以了解女性患者在月经期与排卵期正畸加力后牙齿的移动特征、疼痛程度的改变,丰富正畸学临床理论和方法。方法： 1.首先选取60例于2012年1月至2013年6月间来重庆医科大学附属口腔医院正畸科就诊的青年女性患者,18-23岁、未婚、无生育史,需减数第一双尖牙,采用种植钉支抗的青年女性患者进行月经周期问卷调查、基础体温测定及排卵试纸测定排卵期,筛选出月经周期长度在28-32天,月经量稳定而规律的受试者。按照试验的纳入标准和排除标准,筛选出24例符合试验条件的受试者。2.符合条件的受试者临床中采用统一的矫治技术和方法排齐上颌牙列后,随机分为月经期加力组和排卵期加力组,应用种植体支抗远中移动尖牙。两组受试者均分别于加力前,加力后4周、8周及12周测量两组尖牙向远中移动的距离,同时取模型测量尖牙旋转角度,进行两组间尖牙移动距离和旋转角度差异的统计分析。3.应用目前较为公认的描述疼痛程度级别的视觉模拟评分法(VAS)让受试者分别于加力后的6小时、1天、2天、3天、4天、5天、6天及7天对加力后疼痛的程度进行问卷调查记录。以上研究均采用SPSS18.0软件包对两组尖牙向远中移动的距离、尖牙移动中旋转角度的改变和加力后疼痛程度及延续时长进行进行独立样本t检验统计学分析比较。结果：1、月经期加力组尖牙向远中移动距离明显大于排卵期加力组,差异有明显统计学意义(p0.05)。2、月经期加力组尖牙旋转度大于排卵期加力组,有明显统计学差异(p0.05)。3、两试验组间加力后产生疼痛的程度无明显统计学差别(p0.05)。结论：1、青年女性月经期加力尖牙远中移动距离及旋转角度的改变明显大于排卵期加力,提示在青年女性患者月经期加力牙齿移动较快,可以提高矫治效率,同时也需密切关注该时期支抗控制。2、两试验组间加力后产生的疼痛程度无明显差异,提示在本试验条件下,疼痛不能作为女性月经期正畸加力的禁忌症。
[Abstract]:Objective: to investigate the effect of postmenopausal stress on orthodontic tooth movement in young female patients during menstrual period and ovulatory period. To understand the characteristics of tooth movement and the change of pain degree of female patients after orthodontic treatment during menstrual period and ovulation stage, and to enrich the clinical theory and methods of orthodontics. Methods: 1. From January 2012 to June 2013, 60 young female patients, aged 18-23 years, who were admitted to the Orthodontics Department of the affiliated Stomatology Hospital of Chongqing Medical University, were selected. They were unmarried, had no history of childbearing, and needed to reduce their first bicuspid teeth. The menstrual cycle questionnaire was conducted in young female patients with implant nail Anchorage, the ovulation period was measured by basic body temperature test and ovulation test paper, and the subjects whose menstrual cycle length was 28-32 days and menstrual volume stable and regular were selected. According to the inclusion criteria and exclusion criteria, 24 eligible subjects were selected. The subjects were randomly divided into two groups: postmenopausal stress group and ovulatory stress group. Implant Anchorage was used to resist distal canine movement. The distance between the two groups was measured before, 4 weeks, 8 weeks and 12 weeks after the application. The model was used to measure the rotation angle of the canine teeth, and the statistical analysis was made on the distance and rotation angle of the canine teeth between the two groups. The visual analogue scale (VAS), which is widely used to describe the degree of pain, was used to record the degree of pain at 6 hours, 1 day, 2 days, 3 days, 4 days, 5 days, 6 days and 7 days. SPSS18.0 software package was used to analyze and compare the distance between the canine teeth to the distal distance, the rotation angle during the canine movement and the pain degree and duration of the canine movement. Results: 1. The distance of distal movement of canine in menstruating group was significantly longer than that in ovulatory group (p0.05). 2. The rotation degree of canine in menstruating period was greater than that in ovulatory poststimulation group. There was significant statistical difference (p0.05). 3. There was no significant difference in the degree of pain after adding force between the two groups (p0.05). Conclusion: 1. The change of the distance and rotation angle of extra force canine teeth in young women during menstrual period is obviously larger than that in ovulatory period, which suggests that the tooth movement of young female patients during menstrual period is faster and can improve the efficiency of correction. At the same time, we also need to pay close attention to the control of Anchorage in this period. 2. There is no significant difference in pain degree between the two groups after adding force, which suggests that pain can not be regarded as contraindication of orthodontic stress in female menstrual period under this experimental condition.
