目的:评价丁硼乳膏在固定正畸中预防牙龈炎发生的临床效果。方法:选择黄石市疾病预防控制中心口腔门诊2011年7月~2013年9月就诊前未患牙龈炎的青少年固定正畸患者120例为研究对象,随机分为干预组(丁硼乳膏刷牙)和对照组(普通牙膏刷牙),每组60例,分别检测正畸治疗前和治疗4周后牙周指数(牙龈指数GI、菌斑指数PLI、龈沟出血指数SBI),并进行组间均数的t检验分析。结果:对照组治疗4周后GI、PLI和SBI均显著上升,治疗前后有统计学差异(P0.001),而干预组未见明显改变,治疗前后亦无统计学差异(P0.05)。结论:丁硼乳膏对口腔中常见细菌有抑制作用,能有效维护固定正畸治疗中的牙周健康及预防牙龈炎的发生。
