目的了解全国44家分布在地级以上城市的公立口腔医疗机构医师对乳牙牙髓切断术的认识,开展情况及乳牙深龋洞时的治疗倾向。方法本研究采用研究者自行设计的调查问卷,调查对象根据自己的情况选择填写A卷或B卷。结果共回收了来自44家医疗机构的103份有效问卷。46.6的调查对象有乳牙牙髓切断术的临床经验。有牙髓切断术诊疗经验的医师中,只有17.39在适应证时选择牙髓切断术。有乳牙牙髓切断术临床经验的医师普遍更认同乳牙也应尽量保存活髓。进行乳牙牙髓切断术诊疗的医师有97.72使用氢氧化钙作为盖髓剂。两组医师对乳牙是否也应尽量保存活髓认知有差异。结论乳牙牙髓切断术在我国开展不普遍,且操作不够规范。氢氧化钙是乳牙牙髓切断术中主要使用的盖髓剂。调查结果显示应加强此项技术的临床教学与培训工作。
