Periodontium including zones of gingiva and periodontal fiber groups: A mandibular left first premolar is sus- pended in its alveolus by the five groups of periodontal ligament fibers: apical, oblique, horizontal, alveolar crest, and free gingival fibers are visible. A sixth group, called transseptal fibers, not visible in this drawing, attaches from the cementum of one tooth to the cementum of the adjacent tooth at a level between the free gingival and alveolar crest fibers. The fibers of the periodontal ligament are much shorter than depicted here, averaging less than ¼ of a millimeter. The periodontal ligament is made As discussed in detail in Chapter 7 (Periodontics), up of four groups of fibers with differing directions and healthy gingiva varies in appearance from individual attachments and different names.

A healthy papilla conforms to the space between two teeth (interproximal space), so from the facial view it comes to a point near where the adjacent teeth contact. The papilla also has the hidden sulcus (potential space) next to each tooth where dental floss can fit once it passes between the teeth. Attached gingiva is a band or zone of gray to light or coral pink (possibly with melanin pigmentation) keratinized masticatory mucosa that is firmly bound to the underlying bone (Fig. It extends between the free gingiva (at the free gingival groove if present) and the more movable alveolar mucosa.

These databases are compiled as follows: published papers are scrutinized and allocated keywords which are then indexed zyprexa 7.5 mg mastercard symptoms for bronchitis. Normally buy zyprexa american express medications recalled by the fda, the reference is given in the form of name purchase 10 mg zyprexa free shipping medications vs grapefruit, date of pub- lication purchase cheap zyprexa symptoms 5dp5dt fet, title of publication, title of journal in which the information is held and possibly an abstract for the paper. As an added bonus, some databases provide a link to an electronic copy of the full version of the paper. Electronic journal databases are useful when you know exactly what you are looking for and have a reference for a particular journal article. You can locate the journal you need and from that you can locate the particular article you need to get hold of. It is usually organized via an A–Z section which con- tains access to the electronic copy of the papers (journal articles). It is impor- tant to note that the electronic journal database does not allow you to search for what is written on your topic (the subject specifc database is better for this) but is useful to locate the sources identifed from the subject specifc databases. Getting started using databases Identify relevant databases to which you have access. Various health and social care databases will be available through professional websites, univer- sity or organizational libraries to which you belong. Different databases access literature from different countries or groups of countries or focus on specifc specialities or interest areas. Cochrane have a collection of databases in their ‘webliography’ available at http://www. Joanna Briggs Institute: systematic reviews, evidence summaries and best practice information sheets in nursing and allied health from the Joanna Briggs Institute. Web of Science: includes Science Citation Index and Social Sciences Citation Index. Covers about 20,000 current journals and conference proceedings in many key subject areas. This will reduce the number of hits you get as each term must be included in the article for it to be recognized. This will increase the number of hits you get as you only need to identify one of the terms for the article to be selected. There is also the ‘* facility’ which enables you to identify all possible end- ings of the key term you write. You need to identify the ‘root’ of the word for example, the part of the word that doesn’t change – and put the * after that last letter. For example: child* will identify articles containing child, children, children’s and so on. If you are a practice assessor/mentor, ask your student to show you how to search. Try and identify search terms for a question you have using this table (you can add rows or columns as you need to). You will fnd that you will develop new ideas as you undertake the searching pro- cess. You might fnd, for example, a key theme is called by a different name or phrase that you had not previously thought of. Once you have identifed the key literature on your topic using one data- base, you could repeat the search using another database. If you fnd that the same references are thrown up, then you can be confdent that your strategy is well focussed and that you are accessing the relevant literature on your topic.
