BACKGROUND
To establish the extent of using nickel titanium rotary instruments (NiTi-RIs), to identify reasons for using / not using NiTi-RIs, to explore usage modalities and to identify factors and measures that can increase implementation of NiTi-RIs in general dental practice.
METHODS
Two pilot questionnaires were conducted on academic staff members at College of Dentistry, Taibah University, general dentists (GDs) and endodontists to finalise the questionnaire. A sample size was calculated considering the expected and minimum accepted response rates (60 and 48%, respectively) and a 99.9% Confidence Level. The online-questionnaire was sent to 600 GDs and all endodontists (175) working in Saudi Arabia. A reminder was emailed after 10 weeks to encourage non-respondents to complete the questionnaire. Responses, were collected and converted into numerical data which were analysed using the Chi-square test (p = 0.05).
RESULTS
Significantly most respondents (71.9%) used NiTi-RIs (p < 0.001); with more endodontists (96.9%) than GDs (60%). Most users (62.5%) had been using NiTi-RIs for More than 3 years (p < 0001). The trend of using NiTi-RIs increased as participants' experience and the number of root-canal treatments performed per week increased (p = 0.021). While most respondents (45.3%) used NiTi-RIs because of faster root-canal preparation, the majority of non-users (85.3%) didn't do so because of high cost. The highest proportion (43.3%) reported better undergraduate education as the most important factor that can significantly increase NiTi-RIs usage. The majority (91.8%) prepared glide-path before using NiTi-RIs; especially with stainless steel hand-files (63.3%).
CONCLUSIONS
NiTi-RIs are relatively well adopted in Saudi dental practice. However, better education, especially during undergraduate training and lower cost can increase their usage. Overall, clinicians showed good awareness of NiTi-RIs usage aspects which reflected on usage modalities.
背景
确定镍钛旋转器械（NiTi-RIs）的使用程度，确定使用/不使用 NiTi-RIs 的原因，探索使用方式，并确定可以增加一般牙科实践中 NiTi-RIs 实施的因素和措施。
方法
在塔伊巴大学牙科学院的学术人员、普通牙医（GDs）和牙髓病学家中进行了两项试点问卷，以确定问卷的最终形式。考虑到预期和最低可接受的回复率（分别为 60%和 48%）和 99.9%置信水平，计算了样本量。在线问卷发送给了 600 名 GDs 和在沙特阿拉伯工作的所有牙髓病学家（175 名）。在 10 周后通过电子邮件发送提醒，以鼓励未回复者完成问卷。将回复转换为数值数据，并使用卡方检验（p=0.05）进行分析。
结果
大多数受访者（71.9%）确实使用了 NiTi-RIs（p<0.001）；牙髓病学家（96.9%）的使用率高于 GDs（60%）。大多数使用者（62.5%）使用 NiTi-RIs 的时间超过 3 年（p<0.0001）。随着参与者的经验和每周进行的根管治疗次数的增加，使用 NiTi-RIs 的趋势增加（p=0.021）。虽然大多数受访者（45.3%）因为更快的根管预备而使用 NiTi-RIs，但大多数非使用者（85.3%）因为成本高而不这样做。报告说更好的本科教育是最重要的因素，可以显着增加 NiTi-RIs 的使用率，这一比例最高（43.3%）。大多数受访者（91.8%）在使用 NiTi-RIs 之前准备了滑模，特别是使用不锈钢手用锉（63.3%）。
结论
NiTi-RIs 在沙特牙科实践中得到了相对较好的采用。然而，更好的教育，尤其是在本科培训期间和更低的成本可以增加它们的使用。总体而言，临床医生对 NiTi-RIs 使用方面表现出了良好的认识，这反映在使用方式上。
