摘　　要：目的基于问卷调查分析乳磨牙金属预成冠的临床应用情况及影响因素,为金属预成冠的临床普及提供参考。方法选择2013年6至12月及2022年6至12月来自全国各地的儿童口腔医师,通过线上、线下结合的方式发放调查问卷,分析乳磨牙金属预成冠临床应用情况及其影响因素。结果2013和2022年分别发放调查问卷712及580份,回收有效问卷608及512份,问卷有效回收率为85.4%及88.3%。2022年金属预成冠的使用率[78.1%(400/512)]显著高于2013年[52.6%(320/608)](χ^(2)=78.68,P<0.001)。2013年未选择金属预成冠修复的主要原因为技术敏感性高[52.8%(152/288)],其次为冠边缘对牙龈的影响[50.0%(144/288)]及美观性差[27.8%(80/288)];而2022年未选择金属预成冠修复的主要原因为医院或诊所尚未配备[53.6%(60/112)]及美观性差[21.4%(24/112)]。2013及2022年选择金属预成冠修复的主要原因为保护作用好、牙齿折裂少,分别占78.1%(250/320)及82.5%(330/400),其次为脱落率低,分别占62.5%(200/320)及68.0%(272/400)。2013及2022年乳磨牙根管治疗后选择金属预成冠修复的比例分别为51.3%(312/608)和76.6%(392/512),2022年显著高于2013年(χ^(2)=75.88,P<0.001)。乳磨牙深龋盖髓后选择金属预成冠修复的比例分别为13.2%(80/608)和53.1%(272/512),2022年亦显著高于2023年(χ^(2)=206.01,P<0.001)。结论从2013至2022年金属预成冠的技术敏感性降低,在我国的应用占比提高,但部分医院尚未配备,限制了金属预成冠的应用,金属预成冠的临床普及还需要进一步推动。Objective To provide references for the clinical popularization of stainless steel crowns by analyzing the clinical application and affecting factors of stainless steel crowns used in primary molars based on a questionnaire survey.Methods Pediatric dentists from all over the country in June to December 2013 and June to December 2022 were selected to answer the survey questionnaire through the online or offline methods for analyzing the clinical application and influencing factors of stainless steel crowns used in primary molars.Results A total of 712 and 580 questionnaires were distributed,and 608 and 512 valid questionnaires were recovered respectively in 2013 and 2022.The effective rates of the questionnaires were 85.4%and 88.3%.Among them,the usage rates of stainless steel crowns in 2013 and 2022 were 52.6%(320/608)and 78.1%(400/512)respectively,with a statistically significant difference(χ^(2)=78.68,P<0.001).The main reasons for not selecting stainless steel crowns in 2013 were high technical sensitivity[52.8%(152/288)],followed by the impact of crown edge on gingiva[50.0%(144/288)]and poor aesthetics[27.8%(80/288)],while in 2022 were the inadequate equipage in hospitals[53.6%(60/112)]and poor aesthetics[21.4%(24/112)].The main reasons for choosing stainless steel crowns restoration were good protection effect,less tooth fracture[78.1%(250/320)in 2013 and 82.5%(330/400)in 2022],followed by low dropout rate[62.5%(200/320)in 2013 and 68.0%(272/400)in 2022].The proportions of stainless steel crowns restoration for primary molars after root canal therapy were 51.3%(312/608)and 76.6%(392/512)respectively with statistically significant(χ^(2)=75.88,P<0.001).The proportions after pulp capping treatment for deep caries were 13.2%(80/608)and 53.1%(272/512)respectively,and the difference was statistically significant(χ^(2)=206.01,P<0.001).Conclusions During the 10 years from 2013 to 2022,the technical sensitivity of stainless steel crowns had gradually decreased,and the application in China had gradually increased.Ho
