6. Search Engines Definition Tool for finding information, especially on the Internet o r World Wide Web. Most consist of three parts:  at least one program, called a spider, crawler, or bot, which “crawls” through the Internet gathering information;  a database, which stores the gathered information;  a search tool, with which users search through the database by typing in keywords describing the information desired. 6

17. Check your Knowledge Question What are the differences between search engines Google and Google Scholar? 17

18. Answer Check your Knowledge Answer  Google Scholar offers scientific articles whilst  Google collects websites containing various document types, formats and quality. 18

19. Module 1 Take-home-message 1. Before information retrieval, formulate research questions, get ready proper search terms. 2. Search engine Google : use Advanced search. 3. Search engine Google Scholar : use to locate journal articles 4. Quality of health-related websites : European Commission policy paper (2002). 19

37. 37 Module 2 Take-home message 1. Use bibliographic database MEDLINE/PubMed to answer research question „Dental caries risk and prevention in schoolchildren“ 2. Tools for precise building search strategy (occurrence of search terms in different database fields, application of Boolean operators, additional filters). 3. Navigation across results (citation – structured abstract – fulltext sources).

38. Modul 2 Take-home message 4. Knowledgebases are convenient for searching more complex research questions, eg. interaction betwen oral and general health, in particular cardiovascular risks. 5. DYNAMED is a synoptic database, fee-based. Hyperlinked references with some fulltext, navigated to PubMed). 6. UPTODATE is a fulltext knowledgebase; hyperlinked graphs, tables, images, PubMed references. 38
