臭氧应用于口腔器械消毒

随着人们健康水平的提高,口腔器械的消毒问题正日益受到医务人员的重视。尤其是手机、超声波洗牙机头、假牙托盘等特殊器械的消毒现在还没有一个较理想的消毒方法。常规的消毒方法往往不尽如人意,例如高压蒸汽、气体薰蒸、消毒溶液浸泡、紫外线辐射等,这些方法有的会影响器械的使用寿命;有的消毒效果欠佳;有的价格高,毒性散发过程长。因此目前对部分特殊的口腔器械消毒尚不够严格。口腔内各种细菌、病原体都可能存在,据初步估计,现在世界上乙肝表面抗原(HBsAg)的携带者超过 2亿。乙肝病毒的传染性很强。近来有人报告在急性乙型肝炎患者和慢性HBsAg携带者的唾液标本中检测到HBsAg及Dane颗粒。因此,HBsAg随唾液经口传播的途径应引起重视。在此,我们介绍一种最近研制成功的消毒仪器—“GY901型口腔器械气体消毒器”,该仪器由上海师范大学研制,华东医院监制。仪器采用高浓度臭氧气体对口腔器械进行消毒,与常规的消毒方法比较有其独特的优点。

部分口腔外科常用器械消毒后的细菌学研究

本文就1983—1987年间部分口腔外科消毒器械作需氧细菌培养及存放这些器械的消毒柜作空气细菌培养,其结果,器械细菌培养均属正常范围,空气细菌培养数除少数几次超出正常范围外,绝大部分属正常范围。器械细菌培养阳性率有上升的趋势,可能与就诊人数的增加和消毒不严有关,应加强器械的消毒工作。而空气细菌培养阳性数则有下降的趋势,这与加强了空气的消毒有关。

口腔诊疗器械的消毒灭菌措施及体会

口腔科诊疗器械种类繁多、结构复杂、材质各异,应根据其不同特点采用不同的消毒方法,既要达到消毒的目的,还要满足临床上用量大周转快的需求,同时还要考虑尽可能延长诊疗器械的使用年限。针对以上三点我科在临床工作中就不同的器械采用不同的消毒方法积累了一些经验。本文就我科诊疗器械的消毒灭菌措施及体会作一总结。

口腔扁平苔藓诊断标准的发展与中国化

口腔扁平苔藓(oral lichen planus,OLP)是一种常见的口腔黏膜慢性炎性疾病,其诊断标准是临床诊治和科学研究的基石,但目前对诊断标准的认识并不统一,特别是国际的诊断标准如何与我国具体国情结合,应用于临床,指导我国的临床工作和科学研究,这些问题亟待解决。本文对国际上OLP诊断标准的发展、内容特点、差异度等进行系统介绍和讨论,并结合切身临床和研究经验以及我国临床医师的具体实际,提出OLP诊断中活检适应证选择的"23原则",并对其他与OLP诊断相关的热点问题提出建议。     

Classification and diagnostic criteria for oral lesions in HIV infection

A consensus has been reached on the classification of the oral manifestations of HIV infection and their diagnostic criteria, based on presumptive and definitive criteria. The former relate to the initial clinical appearance of the lesion and the latter are often the result of special investigations. Candidiasis, hairy leukoplakia, specific forms of periodontal disease [linear gingival erythema, necrotising-(ulcerative) gingivitis and necrotising(ulcerative) periodontitis], Kaposi's sarcoma and non-Hodgkin's lymphoma are strongly associated with HIV infection. Lesions less commonly associated with HIV infection and lesions seen in HIV infection, but not indicative of the disease, are also listed.     

Development of a validated process for manual preparation of dental transmission instruments

The goal of the study was to develop a validated manual preparation process that conforms to the requirements of validation guidelines. Twelve dental transmission devices from various manufacturers (turbines, handpieces, and contra-angle handpieces) were artificially contaminated with bovine hemoglobin for the test. Ten microliters (corresponding to 800 μg) of bovine hemoglobin solution (concentration 80 mg/ml) was pipetted into the spray water and spray air channels. The manual preparation was conducted by blowing air through the spray channels of the transmission instruments through an attachment to a treatment unit (model 1060T, KaVo, Biberach, Germany) for 5 s. The spray channels were cleaned with WL-Clean (Alpro, Georgen, Germany) as directed by the manufacturer. The spray channels were disinfected with WL-Cid (Alpro) and the spray channels were blow-dried with WL-Dry (Alpro) at the end of the exposure time as directed by the manufacturer. To determine the protein content (protein residue analysis) in the channels of the transmission instruments, 2 ml of an alkaline SDS solution (1%; pH 11) was flushed through the channels. For the quantitative protein residue analysis, the Biuret method was used as described in DIN EN 15883-1:2006. After the application of this method, all results of the protein residue analysis were within the acceptance criteria of the validation guideline. The newly developed manual preparation process is therefore confirmed as suitable from a hygienic viewpoint for preparation of transmission instruments in the dental practice.
