Prosthodontic practice involves procedures in which impressions of the maxillary and mandibular arches are mandatory. Cross infection is one of the major problems that can occur in regular dental practice. Every dentist should take utmost care to prevent cross infection as oral cavity is the source of variety of microorganisms which can often cause diseases that can be fatal. Although precautions, such as wearing of gloves and mask, sterilization of instruments are given importance, the need for disinfection of impressions is often neglected. Hence, the aim of the study was to assess the disinfection potential of radiofrequency glow discharge (RGD) by microbiological studies.
Disinfection potential of RGD on addition silicone (Reprosil, Dentsply, Milford DE, USA) was assessed. Total sample size was 20. Samples were divided into two groups of 10 each. Group I - control group and group II -RGD-treated group. Main groups were subdivided into subgroups A and B. Data collected were analyzed.
The RGD-treated samples were found to be culture sterile which meant that there were no signs of growth of any organisms, thus proving the disinfection potential of RGD.
From this study, we can conclude that RGD is a very rapid and handy device, which can disinfect saliva contaminated elastomeric impression material surfaces.
When compared with the difficulties and lack of efficiency encountered in disinfecting impressions by immersion and spray atomization, RGD can be very handy in dental clinics, as it is a very rapid and convenient method for infection control.
口腔修复实践涉及对上颌和下颌牙弓取印模的操作。交叉感染是常规牙科实践中可能出现的主要问题之一。每位牙医都应格外小心预防交叉感染，因为口腔是多种微生物的来源，这些微生物常常会引发可能致命的疾病。尽管诸如戴手套和口罩、器械灭菌等预防措施受到重视，但印模消毒的必要性却常常被忽视。因此，本研究的目的是通过微生物学研究评估射频辉光放电（RGD）的消毒潜力。
评估了RGD对加成型硅橡胶（Reprosil，登士柏，美国特拉华州米尔福德）的消毒潜力。总样本量为20个。样本分为两组，每组10个。第一组为对照组，第二组为RGD处理组。主要组再细分为A组和B组。对收集的数据进行分析。
经RGD处理的样本被发现无菌培养，这意味着没有任何生物体生长的迹象，从而证明了RGD的消毒潜力。
从本研究中，我们可以得出结论，RGD是一种非常快速且便捷的设备，能够对被唾液污染的弹性印模材料表面进行消毒。
与通过浸泡和喷雾雾化对印模进行消毒时遇到的困难和效率低下相比，RGD在牙科诊所可能会非常方便，因为它是一种非常快速且便捷的感染控制方法。
