A questionnaire survey was recently undertaken among French dental students (FDSs) to investigate their practices, knowledge and opinions in various domains of minimal intervention (MI) in cariology. The present work focuses on management of deep carious lesions (DCLs).
The questionnaire was administered (Spring 2018) to all the fifth-year students of the 16 French dental schools. Descriptive analyses were performed.
Among 1370 FDSs (response rate: 84.5%), hardness was the most commonly reported criterion for assessing the endpoint of carious tissue removal (53.9%), followed by firm dentin (40.0%). Regarding FDSs' opinion of leaving carious dentine under a restoration, 41.9% of the respondents agreed that carious tissues should always be removed completely. For an asymptomatic tooth with DCLs and exposed pulp, direct pulp capping was mainly chosen (93.9%). In a clinical case correctly diagnosed as a reversible pulpitis by 79.7% of respondents, nearly half of FDSs chose a one-step complete excavation (48.3%) followed by selective excavation (25.1%), then two-step complete excavation (20.9%) and a minority (5.7%) opted for pulpal therapy (biopulpotomy or endodontic treatment).
The present results suggest an inadequate dissemination of MI concepts among FDSs towards DCL management. The present results show the need for a harmonisation and a reinforcement of teaching evidence-based MI according to the latest European recommendations.
最近对法国牙科学生（FDS）进行了问卷调查，以调查他们在龋病学的各个微创（MI）领域的实践、知识和观点。本研究重点关注深龋病损（DCL）的管理。
该问卷于 2018 年春季向法国 16 所牙科学校的所有五年级学生发放。进行了描述性分析。
在 1370 名 FDS 中（应答率：84.5%），硬度是评估龋坏组织去除终点最常报告的标准（53.9%），其次是硬组织（40.0%）。关于 FDS 对在修复体下保留龋坏牙本质的看法，41.9%的受访者认为应始终彻底去除龋坏组织。对于有 DCL 和暴露牙髓的无症状牙齿，主要选择直接盖髓术（93.9%）。在由 79.7%的受访者正确诊断为可逆性牙髓炎的临床病例中，近一半的 FDS 选择了一步法完全挖除（48.3%），其次是选择性挖除（25.1%），然后是两步法完全挖除（20.9%），少数（5.7%）选择牙髓治疗（活髓切断术或根管治疗）。
目前的结果表明，FDS 对 DCL 管理的 MI 概念传播不足。目前的结果表明，根据最新的欧洲建议，需要协调和加强基于证据的 MI 教学。
