One of the key aspects of improving the dental care we offer to our patients is in basing our practice on the best available evidence.
The main purpose of this paper is to present some basic ways of searching reliable papers on Internet and to introduce some techniques to facilitate the development of strategic search skill to improve the quality of dental care, using dental trauma as an example.
After formulation of a clinical question on a dental trauma issue, a comparison was made between: data collected in PubMed using a given term; data collected in PubMed using the Medical Subject Headings vocabulary (Mesh) and data collected using the principles of evidence-based research, all by an independent researcher. A number of papers searched about a clinical question on dental trauma and a brief commentary about each Internet research database is presented. The authors reported that the best sites available to perform the sample search were those produced by academic centers, professional organizations and government-sponsored. To get evidence-based clinical papers we did internet search on PubMed, Cochrane, Center of Evidence-Based Dentistry and Knowledge Finder using the clinical question "Emergency Treatment for Avulsed Tooth".
All searched databases were efficient for scientific journals, but when we used the PI strategy, the search seemed to be more relevant and specific. The Cochrane, Center of Evidence-Based Dentistry and Knowledge Finder presented more reliable papers to answer our clinical question about dental trauma treatment.
It is imperative that dentists understand the advantages of searching the Internet and learning to use it effectively to guide practice and assist their patients in their pursuit for better oral health.
改善我们为患者提供的牙科护理的关键方面之一是将我们的实践建立在现有最佳证据的基础上。
本文的主要目的是以牙外伤为例，介绍一些在互联网上搜索可靠论文的基本方法，并介绍一些有助于发展策略性搜索技能以提高牙科护理质量的技巧。
在就牙外伤问题提出临床问题后，由一名独立研究人员对以下各项进行比较：使用特定术语在PubMed中收集的数据；使用医学主题词表（Mesh）在PubMed中收集的数据；以及使用循证研究原则收集的数据。展示了一些关于牙外伤临床问题搜索到的论文，并对每个互联网研究数据库进行了简要评论。作者报告称，进行样本搜索的最佳网站是学术中心、专业组织和政府资助机构制作的网站。为了获取循证临床论文，我们使用临床问题“脱位牙的急诊治疗”在PubMed、Cochrane、循证牙科中心和知识查找器上进行了互联网搜索。
所有搜索的数据库对科学期刊都很有效，但当我们使用PI策略时，搜索似乎更相关、更具体。Cochrane、循证牙科中心和知识查找器提供了更可靠的论文来回答我们关于牙外伤治疗的临床问题。
牙医必须了解在互联网上搜索的优势，并学会有效地利用它来指导实践，帮助患者追求更好的口腔健康。
