The risk of dental assistants acquiring injury and infections from the dental clinics has received little attention, especially in South Africa.
To determine the prevalence of occupational exposures among dental assistants working in public health care facilities in Limpopo Province.
A cross-section study on infection control practice and occupational exposures was conducted among 73 dental assistants.
The sample was predominantly female (95%) with a mean age of 40.2 years (age range 23-54 years). Almost half the respondents (49.1%) had no formal training for their occupation, 22% were nursing assistants and only 10.2% had qualified at a technical college (Technicon). The mean number of clinicians assisted by each participant was 3.8 (SD +/- 1.9). Nearly half of the dental assistants (n = 26) reported an occupational exposure, half of which in turn occurred while handling instruments and 42.3% while assisting. The most common type of injury was a direct puncture (65.3%). Treatment included antiretroviral therapy (19.2%) and wound-cleaning (38.4%), while 42.3% reported that they had had no treatment at all. About 23% of incidents were not reported. Eighty percent changed gloves routinely between patients but 67% did not use protective eye glasses; 62.7% were not vaccinated against HBV.
Occupational exposure was found to be unacceptably high and compliance of infection control guidelines was low.
牙科助理在牙科诊所面临受伤和感染的风险很少受到关注,尤其是在南非。
确定林波波省公共卫生保健机构中牙科助理职业暴露的患病率。
对73名牙科助理进行了一项关于感染控制实践和职业暴露的横断面研究。
样本主要为女性(95%),平均年龄40.2岁(年龄范围23 - 54岁)。几乎一半的受访者(49.1%)没有接受过正式的职业培训,22%是护理助理,只有10.2%毕业于技术学院(理工学院)。每位参与者协助的临床医生平均人数为3.8(标准差±1.9)。近一半的牙科助理(n = 26)报告有职业暴露,其中一半是在处理器械时发生的,42.3%是在协助时发生的。最常见的损伤类型是直接穿刺(65.3%)。治疗包括抗逆转录病毒疗法(19.2%)和伤口清洗(38.4%),而42.3%的人报告说他们根本没有接受治疗。约23%的事件未报告。80%的人在患者之间常规更换手套,但67%的人未使用防护眼镜;62.7%的人未接种乙肝疫苗。
发现职业暴露程度高得令人无法接受,感染控制指南的依从性低。
