To analyze the clinical application and limiting factors of the Hall technique (HT) preformed metal crowns in caries of primary molars and to provide reference for its clinical application based on a questionnaire survey.
From June to December 2022, a questionnaire was distributed to pediatric dentists through the WeChat platform using "Questionnaire Star" to analyze the clinical application and influencing factors of the HT preformed metal crowns in caries of primary molars.
A total of 700 survey questionnaires were distributed, and 650 valid questionnaires were recovered, with a effectiveness rate of 92.86%. In terms of the awareness level of the HT, only 11.08% of pediatric dentists fully understood, while 19.85% of those were completely unaware; In terms of the understanding methods, classes study accounted for 47.60%, and 28.79% of pediatric dentists understood through literature; In terms of the application of the HT, 46.15% of pediatric dentists had applied it, only 11.23% had frequently applied it, and 53.85% had never applied it; In terms of the usage time, the highest proportion was between 1 and 3 years, accounting for 40.33%, and only 9.67% were over 5 years; In terms of the choosing of indications, only 26.62% of pediatric dentists could select indications correctly; Regarding the choice of treatment methods for children who do not cooperate, only 19.54% of pediatric dentists chose the HT. The education background and nature of the workplace had a statistically significant difference in the application of the HT, the number of years of application, the selection of indications, and the choice of treatment methods for children who do not cooperate.
The survey showed that the awareness level and application frequency of the HT were relatively low in China. The understanding methods mainly learned through classes study.
It is necessary to further promote the development of continuing education projects with the theme of clinical application of the HT and the guidance of clinical operation standards, in order to promote the clinical popularization of it in China.
通过问卷调查分析霍尔技术（HT）预成金属冠在乳牙龋病中的临床应用及限制因素，为其临床应用提供参考。
2022年6月至12月，通过微信平台使用“问卷星”向儿童牙医发放问卷，分析HT预成金属冠在乳牙龋病中的临床应用及影响因素。
共发放调查问卷700份，回收有效问卷650份，有效率为92.86%。在HT的认知水平方面，仅有11.08%的儿童牙医完全了解，而19.85%的儿童牙医完全不了解；在了解途径方面，课堂学习占47.60%，28.79%的儿童牙医通过文献了解；在HT的应用方面，46.15%的儿童牙医曾应用过，仅有11.23%的儿童牙医经常应用，53.85%的儿童牙医从未应用过；在使用年限方面，占比最高的是1至3年，为40.33%，超过5年的仅占9.67%；在适应证选择方面，仅有26.62%的儿童牙医能正确选择适应证；对于不配合患儿治疗方法的选择，仅有19.54%的儿童牙医选择HT。学历背景和工作单位性质在HT的应用、应用年限、适应证选择以及不配合患儿治疗方法的选择上存在统计学差异。
调查显示，HT在我国的认知水平和应用频率相对较低。了解途径主要是通过课堂学习。
有必要以HT临床应用为主题、以临床操作规范为指导，进一步推动继续教育项目的开展，以促进其在我国的临床普及。
