Usage of the Combination of Self-ligiated bracket,Paracetamol,and Orthodontic-wax to Relieve The Incipient Pain of Fixed Orthodontic Therapy

目的探索减轻固定正畸治疗初始疼痛的方法。方法随机选择42例患者作为治疗组,在安放Clippy自锁托槽矫治器前后,嘱患者口服必理通,并发放正畸保护蜡,嘱患者在口腔颊部软组织受到矫治器刺激时自行使用。选择42例采用传统直丝弓矫治器矫治的患者作为对照组。通过问卷调查表了解初始疼痛的发生强度和持续时间,并对其进行统计学分析。结果对照组初始疼痛发生率为92.8%,治疗组初始疼痛发生率为71.4%,两组初始疼痛发生率差异有统计学意义(P<0.05)。治疗组初始疼痛的平均强度减弱,疼痛持续时间缩短。结论自锁托槽、必理通和正畸保护蜡联合应用可有效减轻固定正畸治疗伴发的初始疼痛。
