The aim of this study was to investigate the current knowledge and attitude of deep caries removal method among dental students in Malaysia.
A total of 303 students ( = 303) responded to the online questionnaire. The first part of questionnaire was to evaluate the demographic data of the respondents and focused on the technique and management approach used for deep caries lesion. The second part investigated the preferred treatment used for deep caries based on the designated clinical case, while the third part assessed the factors that affected the decision on deep caries management.
Independent -test was used to compare difference between the two groups.
Seventy four percent of the students have the knowledge of the different methods of caries removal, while 25.8% were only familiar with complete caries removal. The preferred method for deep caries removal in permanent teeth was partial caries removal (53%). For primary dentition, 45.6% of the students prefer to perform pulpotomy as compared with other techniques. There was no significant difference in caries removal method for permanent teeth between undergraduate year of study ( > 0.05), which was partial caries removal at 52.7 and 53.5%, respectively. For primary dentition, the preferred caries removal method was pulpotomy for year 4 (39.8%) and year 5 (52%) students. The popular material to restore deep caries was resin composite (42%) followed by glass ionomer cement (23.3%).
This study showed that partial caries removal was the preferred method despite partial understanding on the identification of the clinical indicators of the technique.
本研究旨在调查马来西亚牙科学生对深龋去除方法的现有知识和态度。
共有303名学生（n = 303）回复了在线问卷。问卷的第一部分用于评估受访者的人口统计学数据，并聚焦于深龋病变所采用的技术和管理方法。第二部分根据指定的临床病例调查深龋的首选治疗方法，而第三部分评估影响深龋管理决策的因素。
采用独立样本t检验比较两组之间的差异。
74%的学生了解不同的龋病去除方法，而25.8%的学生仅熟悉完全去除龋坏组织。恒牙深龋去除的首选方法是部分去除龋坏组织（53%）。对于乳牙，45.6%的学生相比于其他技术更喜欢进行牙髓切断术。在不同本科学习年份的学生中，恒牙的龋病去除方法没有显著差异（P > 0.05），分别为部分去除龋坏组织，比例为52.7%和53.5%。对于乳牙，四年级（39.8%）和五年级（52%）学生首选的龋病去除方法是牙髓切断术。用于修复深龋的最常用材料是树脂复合材料（42%），其次是玻璃离子水门汀（23.3%）。
本研究表明，尽管对该技术临床指标的识别存在部分理解，但部分去除龋坏组织仍是首选方法。
