The aim of this study was to determine the levels of knowledge and attitude of dental practitioners (DPs) toward vital pulp therapy (VPT) of young permanent teeth in Riyadh city, Saudi Arabia.
A descriptive cross-sectional study was carried out by taking convenient sample of general DPs and specialist attending Saudi International Dental Conference, Riyadh, Saudi Arabia. A total of 200 DPs administered a structured, self-administered questionnaire to evaluate their knowledge and attitude toward VPT. The questionnaire comprised four parts: Part I: Characteristics of the study participants; Part II: Items related to indications and diagnosis of VPT; Part III: Questions related to the different VPTs for immature permanent teeth; and Part IV: Dental materials used in VPT and restoration. All the data were entered into the statistical analysis software Statistical Package for the Social Sciences version 21.0 (IBM, Armonk, NY) and analyzed by using descriptive statistics of frequency distribution and percentages for the categorical variables.
A total of 193 (men = 57% [110] and women = 43% [83]) DPs participated in this study with a response rate of 96.5%. Less than half of correct responses were observed with (Item 1) related to the duration of complete closure of root apex (43%) and (Item 14) use of sodium hypochlorite to serve as an excellent diagnostic tool to differentiate irreversible from reversible pulpitis. A high percentage of correct responses were seen with the (Item 9) indirect pulp capping--a procedure performed in a tooth with a deep carious lesion without signs or symptoms of pulp degeneration (75%). All other item responses ranged in between 52% and 72%.
DPs showed fair-to-good knowledge and attitude toward VPT of young permanent teeth. In general, there is a need to improve knowledge and attitude of dental professionals about the VPT by attending continuing dental educational programs.
本研究旨在确定沙特阿拉伯利雅得市牙科从业者（DPs）对年轻恒牙活髓治疗（VPT）的知识水平和态度。
采用描述性横断面研究，选取参加沙特阿拉伯利雅得国际牙科会议的普通DPs和专科医生作为方便样本。共有200名DPs填写了一份结构化的自填问卷，以评估他们对VPT的知识和态度。问卷包括四个部分：第一部分：研究参与者的特征；第二部分：与VPT适应证和诊断相关的项目；第三部分：与未成熟恒牙不同VPT相关的问题；第四部分：VPT及修复中使用的牙科材料。所有数据均录入社会科学统计软件包第21.0版（IBM，纽约州阿蒙克），并使用分类变量的频率分布和百分比描述性统计进行分析。
共有193名DPs（男性 = 57% [110名]，女性 = 43% [83名]）参与了本研究，应答率为96.5%。观察到正确回答率低于一半的情况有：与根尖完全闭合持续时间相关的（第1项）（43%）以及使用次氯酸钠作为区分不可逆性牙髓炎与可逆性牙髓炎的优秀诊断工具的（第14项）。对于间接盖髓术（第9项）——在有深龋病变且无牙髓退变体征或症状的牙齿上进行的操作，正确回答率较高（75%）。所有其他项目的回答率在52%至72%之间。
DPs对年轻恒牙VPT表现出中等至良好的知识水平和态度。总体而言，需要通过参加继续牙科教育项目来提高牙科专业人员对VPT的知识水平和态度。
