To evaluate knowledge regarding the management of deep carious lesions and exposed pulps among undergraduate and postgraduate endodontic students from ten dental institutions across ten countries, and the impact of operator (material, antibiotic prescription) and patient-related (age, symptoms) factors on their treatment protocols.
An online questionnaire was distributed to evaluate student knowledge of the management of deep caries and exposed pulp related to four clinical scenarios. Simple descriptive statistics were used to describe the data and McNemar tests were employed to identify significant differences between the scenarios. The P-value was set at 5%.
A total of 435 undergraduates and 139 postgraduates from ten dental schools participated in this survey. The final survey included 401 responses from undergraduates and 127 from postgraduates for statistical analysis. When symptoms were present, the majority of undergraduate and postgraduate students preferred non-selective (complete) caries removal over selective (partial) caries removal in young patients. The majority of postgraduates preferred partial pulpotomy in younger patients and pulpectomy and root canal treatment (RCT) in older patients. The majority of undergraduates preferred pulpectomy and RCT in both young/old patients when symptoms were present. The majority of undergraduates and postgraduates opted for mineral trioxide aggregate and Biodentine, respectively, when treating the exposed pulp. Systemic antibiotics were not recommended by both undergraduates and postgraduates, regardless of the patient's age and symptoms.
Among the scenarios surveyed, the majority of undergraduates and postgraduates preferred: a) pulpectomy and RCT for older patients in the presence or absence of symptoms; b) hydraulic calcium silicate cements as pulp capping material; and c) did not recommend systemic antibiotics.
The majority of students choose non-selective (complete) caries removal in all cases and if the pulp is exposed, the use of hydraulic calcium silicate cements iwas the preferred material. Systemic antibiotics are considered unnecessary, irrespective of the patient's age and symptoms.
评估来自十个国家的十所牙科机构的本科和研究生牙髓病学专业学生对深龋病变和露髓处理的知识，以及操作者因素（材料、抗生素处方）和患者相关因素（年龄、症状）对其治疗方案的影响。
发放一份在线问卷，以评估学生对与四种临床情况相关的深龋和露髓处理的知识。使用简单描述性统计来描述数据，并采用McNemar检验来确定不同情况之间的显著差异。P值设定为5%。
来自十所牙科学院的435名本科生和139名研究生参与了此次调查。最终调查纳入了401名本科生和127名研究生的回复进行统计分析。当出现症状时，大多数本科和研究生在年轻患者中更倾向于非选择性（完全）去龋而非选择性（部分）去龋。大多数研究生在年轻患者中更倾向于部分牙髓切断术，而在老年患者中更倾向于牙髓摘除术和根管治疗（RCT）。当出现症状时，大多数本科生在年轻/老年患者中都更倾向于牙髓摘除术和RCT。在处理露髓时，大多数本科生和研究生分别选择了三氧化矿物凝聚体和生物活性玻璃。无论患者年龄和症状如何，本科生和研究生都不推荐使用全身抗生素。
在所调查的情况中，大多数本科生和研究生更倾向于：a）无论有无症状，老年患者采用牙髓摘除术和RCT；b）使用水硬性硅酸钙水泥作为盖髓材料；c）不推荐使用全身抗生素。
大多数学生在所有情况下都选择非选择性（完全）去龋，如果牙髓暴露，水硬性硅酸钙水泥是首选材料。无论患者年龄和症状如何，全身抗生素被认为是不必要的。
