目的:研究按照昼夜节律进行正畸加力控制,获得昼夜节律对正畸扩弓治疗中疼痛的影响和作用,为临床上更有效地进行正畸加力治疗后的疼痛控制。方法:34例连续正畸扩弓治疗病例,男18例,女16例,年龄10.8～12.8岁,腕骨片示均处于生长发育高峰期,采用相同固定快速扩弓装置,每日加力时间按照人体昼夜节律规律分为0点、3点、6点、9点、12点、15点、18点、21点8个时段组,每组加力方式相同,利用MPQ疼痛量表进行疼痛程度的观察,通过统计学软件进行余弦拟合及多样本t检验。结果:不同性别对于疼痛的耐受力有区别,女性对于正畸扩弓治疗疼痛的耐受力低于相同情况下男性。正畸加力后疼痛量化结果显示正畸加力后疼痛基本符合昼夜节律规律。峰值出现在0点,而谷值出现在12点的时间节点。结论:人体昼夜节律可以影响正畸扩弓治疗后的疼痛程度。按照昼夜节律进行正畸扩弓矫治可以获得更好的疼痛控制效果。提示正畸扩弓加力较合适在午间进行,这样有利于控制正畸患者的疼痛。
OBJECTIVE: To study the effect of circadian rhythm on orthodontic force control and to obtain the effect of circadian rhythm on the pain in orthodontic expansion surgery, and to control the pain more effectively after orthodontic force therapy in clinical practice. Methods: 34 cases of continuous orthodontic expansion surgery cases, 18 males and 16 females, aged from 10.8 to 12.8 years old, showing the carpal bones were in the peak growth and development, using the same fixed rapid expansion device, daily afterburner time in accordance with the The circadian rhythm of the human body is divided into 0:00, 3:00, 6:00, 9:00, 12:00, 15:00, 18:00, 21:00 period of 8 groups, each with the same mode of force, using the MPQ pain scale for pain level Observe, through the statistical software for cosine fitting and multiple t-test. Results: Different gender differences in the tolerance of pain, women, orthodontic expansion of pain treatment tolerance lower than men under the same conditions. After orthodontic force pain quantification results show that orthodontic force after the pain basically in line with the circadian rhythm. The peak appears at 0 and the valley appears at the 12 o’clock node. Conclusion: The circadian rhythm of the human body can affect the degree of pain after orthodontic augmentation. In accordance with the circadian rhythm of orthodontic expansion surgery can get better pain control. Prompted orthodontic expansion plus force more appropriate in the afternoon, this is conducive to the control of orthodontic patients with pain.
