我国乳牙牙髓切断术临床应用现况调查

A survey on the current status of pulpotomy in primary teeth among dentisits in China

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。

Objective To evaluate the recognition and clinical applications of pulpotomy in primary teeth in 44 public stomatological hospitals, and the theraputical decisions of Chinese dentists on cariously exposed pulps in symptomfree primary teeth. Methods A total of 103 dentists from 44 different hospitals in China completed the questionnaire.The questionnaire consisted of two parts, doctors filled out ＂part A＂ or ＂part B＂ depending on whether they performed pulpotomy in primary teeth. The questionnaire assessed the decision of performing direct pulp capping, pulpotomy or pulpectomy when the pulp was exposed, as well as the materials used for pulp capping. Chi-square test was used for the longitudinal analysis of data. Results 46.6of the dentists answered Part A. Pulpotomy was selected by 17.39of dentists in group A when encountered the situation. 97.72dentists used Calcium Hydroxide as pulp capping agent.There was difference between the two groups in the recognition of the importance of vita pulp treatment in primary teeth.Conclusion Pulpotomy for primary teeth is not widely used in China. Most pediatric dentists use calcium hydroxide as pulp capping agent. The results of this survey also suggest that there is a need for relevant continuing education and clinical training in pediatric dentists in China.
