PURPOSE/OBJECTIVES: Dental care providers are at risk of percutaneous exposure injuries (PEIs) due to the intimate nature of the patient-dentist environment and the routine use of sharp instruments. They are the most vulnerable to accidental exposure of blood-borne viruses. The aim of this study was to determine the types of PEIs sustained by staff and students at the Griffith University Dental Clinic over a 6-year period.
Data were collected regarding PEIs sustained amongst dental staff and students between 2014 and 2019. Data were obtained from the risk incident reporting system (GSafe) and the patient management Software (Titanium), and then analysed using IBM SPSS. The chi-squared tests and multinomial logistic regressions were performed with significance set at <.05.
Over the 6-year period, there were 308 PEIs with an incidence rate of 0.109%, with 67 being needle stick injuries (0.023%). These injuries happened more often in restorative procedures, followed by local anaesthesia and oral surgery. Dental students were at a greater risk of sustaining PEIs (65.6%) when compared with professional staff (34.4%). Most common instruments included needles (21.8%), probes (20.5%) and burs (18.2%).
Overall, the incidence of percutaneous injuries at the Griffith University Dental Clinic was low. The most common instruments were needles, probes and burs, and dental students were at greatest risk of sustaining injuries. Prevention of injuries by not recapping needles, immediate removal of burs from handpieces, the use of cassettes and single-use instruments has effectively decreased PEIs experienced by dental students and staff.
目的/目标：由于医患环境的亲密性以及锐器的常规使用，牙科医护人员面临经皮接触性损伤（PEI）的风险。他们最容易意外暴露于血源性病毒。本研究旨在确定格里菲斯大学牙科诊所工作人员和学生在 6 年内遭受的 PEI 类型。
收集了 2014 年至 2019 年间工作人员和学生遭受的 PEI 数据。数据来自风险事故报告系统（GSafe）和患者管理软件（Titanium），然后使用 IBM SPSS 进行分析。使用卡方检验和多项逻辑回归，显著性水平设为<.05。
在 6 年期间，有 308 例 PEI，发病率为 0.109%，其中 67 例为针刺伤（0.023%）。这些损伤更常发生在修复程序中，其次是局部麻醉和口腔手术。与专业人员（34.4%）相比，牙科学生遭受 PEI 的风险更大（65.6%）。最常见的器械包括针头（21.8%）、探针（20.5%）和车针（18.2%）。
总体而言，格里菲斯大学牙科诊所的经皮损伤发生率较低。最常见的器械是针头、探针和车针，牙科学生受伤的风险最大。通过不回套针头、立即从机头取下车针、使用盒式器械和一次性器械，有效减少了牙科学生和工作人员的 PEI 发生。
