O country has the distinction of being the second most populous countries in the world and it will not be too long to be the numero uno. As has been estimated by the WHO and similar statistical data which has been reported in the literature, we have a very high prevalence of periodontal diseases amongst the masses which in fact has been figured out to be greater than the dental caries. This pos...

Composition of subgingival microbiotas has long been seen as being of primary importance in the etiology of periodontal diseases. Development of advanced molecular methods has improved our knowledge about the role of traditional periodontal pathogens as well as resulted in the recovery of novel pathogen candidates. Detection rates of these microorganisms vary considerably between geographical r...

Nowadays it is accepted that bacteria play an important role in the ethiology of periodontal diseases. It is known that many bacteria types lodge on the surface of the tooth inside a biofilm and that this structure which is defined as bacteria plaque is closely related to periodontal diseases. There are at least around 500 morphological and biochemically different bacteria groups or types that ...

Objective: Periodontitis and atherosclerosis diseases are chronic inflammatory disorders which are highly prevalent in populations. Nonsurgical periodontal intervention belongs to the initial therapy strategy to periodontal diseases. Periodontal pathogen can enter into blood stream through the ulceration epithelial resulting in bacteraemia when periodontitis is severe. The objective is to inves...

1 CHAPTER 1: NATURAL HISTORY OF PERIODONTAL DISEASES 1.1 EPIDEMIOLOGY OF PERIODONTAL DISEASES 1.1.1. Methodological issues 1.1.1.1 Epidemiology—fundamental aspects Epidemiology, according to general definition, deals with the study of determinants of the occurrence of health-related conditions with the scope to identify the alterable causes and apply findings to control the problem (MacMahon & ...

introduction: periodontal disease is one of the most important diseases in health topics. the aim of this study was to determine the effect of periodontal treatment on quality of life. materials and methods: in this quasi-experimental, interventional study, 45 patients with chronic periodontitis were asked to complete the “quality of life” questionnaire before starting the treatment and four mo...

Periodontal diseases, common infectious diseases seen in humans, are characterized by gingival inflammation and a loss of connective tissue and bone around the roots of teeth, which leads to eventual tooth exfoliation. In the past decade, the association between periodontal diseases and the development of systemic diseases has received increasing attention. Periodontal pathogens and their produ...

Although bacterial plaque is primary etiologic factor in the initiation and progression of periodontal diseases, the host’s reactions to the presence of the bacteria are the one which mediates the periodontal tissue destruction. The periodontal tissue destruction is believed to be due to the host response, it is logical to consider therapeutic approaches that modulate the host response in addit...

Background: Periodontal diseases are among the most frequent diseases affecting children and adolescents. These include gingivitis, localized or generalized aggressive periodontitis (a.k.a., early onset periodontitis which includes generalized or localized prepubertal periodontitis and juvenile periodontitis) and periodontal diseases associated with systemic disorders. The best approach to mana...
