High blood pressure and maxillofacial surgeries

Normal 0 false false false EN-US X-NONE AR-SA This article is aimed to evaluate blood pressure changes in 100 patients (Normotensive and hypertensive) of dental clinics. Blood pressure changes were recorded in particular stages: before surgery, 2 minutes after receiving local anesthesia, during surgery and 15 minutes post surgery. Results were analyzed via student paired T test to identify if there were any significant difference between two groups of normotensive and hypertensive and this was dangerous or significant enough to prohibit patients from receiving dental treatments.

R. Amirlo

Normal 0 false false false EN-US X-NONE AR-SA In general, there is a direct relationship between dental restorations and periodontal condition of the mouth. During tooth preparation, it should be considered that gingival tissues (specially biologic width) must be preserved. Incorrect tooth preparation and therefore incomplete impression results in wrong contour of the final cast, plaque accumulation and gingivitis. Hence, Cervical anatomy of the teeth which determines final contour of the restoration is very important. The amount of tooth tissue that should be removed relates to cervical contour of it before preparation. Over contoured restorations inhibit uscular movements and self cleasnsing mechanism. Shoulder finish line is preferred to knife edge due to the final convexity of tooth contour resulted from shoulder preparation. In teeth with cingulum, preparation should be parallel to cervical third of buccal surface. This brings more retention. Final preparation and impression making should not be performed in the same visit.

The role of cytokines in pathogenesis of periodontal and periapical lesions

Normal 0 false false false EN-US X-NONE AR-SA Cytokines are glycoproteins produced specifically by lymphocytes, macrophages, monocytes and many other cells. In fact, They act nonspecifically. Cytokines are not immunoglubolins and unlike them, have not high molecular weight. They regulate immuneresponse as well as in diagnosis and treatment of diseases. Cytokines role in periodontal diseases as well as identifying them in the pathogenesis of some dental and oral diseases and bone loss process is an important issue in dentistry. Hence, this article presents cytokine's role and developments of immunology science in dentistry.

Evolutions of dental caries prevalence and prevention in Iran and other countries

Normal 0 false false false EN-US X-NONE AR-SA During the recent century, the prevalence of dental caries has been changed widely. Therefore, following industrial revolution of Europe in 19th century and industrialization of European countries as well as population increase in the cities and changes in nutritional diets of people, dental caries prevalence has rapidly increased. Thus, by feeling danger and improving awareness, These countries decided to prevent caries. This , lead to a considerable decrease in DMF indices. In developing countries, the situation was reversed and although industrial developments have happened, dental caries prevalence has been gradually increased. In this article, the etiology of these transitions is discussed and analyzed and practical solutions are mentioned.
