目的探讨接受正畸治疗的患者,放置镍钛丝矫治器后,患者疼痛不适的变化规律及其与年龄、性别、进食、说话、时间的关系。方法对接受正畸治疗的56例患者正畸疼痛程度的变化情况分组进行跟踪调查。结果小于16岁组与大于16岁组差异有统计学意义(Z=﹣2.109,P=0.035)。正畸疼痛严重程度的性别差异无统计学意义(Z=-0.479,P=0.632)。疼痛、进食障碍、说话障碍的疼痛度不完全相同,差异有统计学意义(H=10.326,P=0.000)。正畸青少年组及成人组的患者,且部分男女,疼痛的持续时间均以前4 d为明显,9 d后多数患者已基本正常。结论 16岁以下的患者疼痛程度较重;疼痛、进食障碍、说话障碍的疼痛度不完全相同,差异有统计学意义;正畸疼痛高峰期为1~2 d,5 d后明显减轻;而性别与疼痛严重程度均无关。
Objective To investigate the variation of pain discomfort and the relationship with age, sex, eating, speaking and time in patients undergoing orthodontic treatment after placement of nickel-titanium wire appliance. Methods The changes of orthodontic pain in 56 patients receiving orthodontic treatment were followed up. Results There was significant difference between the group less than 16 years old and the group over 16 years old (Z = -2.109, P = 0.035). Sex differences in the severity of orthodontic pain were not statistically significant (Z = -0.479, P = 0.632). Pain, eating disorders, dysarthria were not exactly the same pain, the difference was statistically significant (H = 10.326, P = 0.000). Orthodontic adolescent group and adult group of patients, and some men and women, the duration of pain were 4 days before the obvious, after 9 days most of the patients have been normal. Conclusion The pain of patients under 16 years of age is severe. The pain degree, eating disorder and speaking disorder are not the same, the difference is statistically significant. The peak of orthodontic pain is 1 ~ 2 days and obviously reduced after 5 days. Not related to the severity of the pain.
