Abstract：
The International Caries Consensus Collaboration (ICCC) has published recommendations on carious tissue removal to treat cavitated carious lesions in a manner that preserves hard tissue and retains teeth long term. This study quantifies The National Dental Practice-Based Research Network dentists\' use of selective caries removal.
This cross-sectional questionnaire study assessed reported use of selective caries removal when treating deep caries in asymptomatic and symptomatic teeth in response to clinical case scenarios. Statistical methods included the proportion of respondents concordant with ICCC guidelines at various thresholds and logistic regression to model factors associated with concordance.
A total of 500 dentists responded. The study sample was 57% male, mean (SD) age was 50.9 (12.6) years, and 60% worked in private practice settings. Higher levels of concordance for choosing selective caries removal 50% or greater of the time were found for asymptomatic (62.4%; 95% CI, 57.6 to 67.2) than for symptomatic caries (49.3%; 95% CI, 44.4 to 54.2). These differences were significantly associated with type of practice setting.
The National Dental Practice-Based Research Network dentists reported using selective caries removal strategies when managing deep carious lesions more often than in previous US and Japanese practice-based research network studies and from results of a systematic review and meta-analysis. Nonetheless, substantive discordance with the ICCC guidelines was seen by the authors of this study.
More dissemination and continuing education activities, as well as implementation studies, may further encourage use of selective caries removal to soft or firm dentin when indicated.

摘要：
国际龋齿共识合作组织（ICCC）发布了有关龋齿组织去除的建议，以保留硬组织并长期保留牙齿的方式治疗空洞的龋齿病变。这项研究量化了基于国家牙科实践的研究网络牙医对选择性龋齿去除的使用。
这项横断面问卷调查研究评估了在无症状和有症状的牙齿中治疗深龋时选择性龋齿去除的使用，以应对临床病例。统计方法包括在各种阈值下与ICCC指南一致的受访者比例，以及与一致性相关的模型因素的逻辑回归。
共有500名牙医做出了回应。研究样本为57%的男性，平均（SD）年龄为50.9（12.6）岁，60%在私人执业环境中工作。选择选择性龋齿清除的一致性水平在无症状的情况下（62.4％；95％CI，57.6至67.2）高于有症状的龋齿（49.3％；95％CI，44.4至54.2）。这些差异与练习设置的类型显着相关。
国家牙科实践为基础的研究网络牙医报告说，与以前的美国和日本实践为基础的研究网络研究相比，在管理深层龋齿病变时，使用选择性龋齿去除策略的频率更高，并且来自系统评价和荟萃分析的结果。尽管如此，本研究的作者认为与ICCC指南存在实质性不一致.
更多的传播和继续教育活动，以及实施研究，可能会进一步鼓励使用选择性龋齿去除柔软或坚固的牙本质。
