Necrotizing periodontal diseases are the serious inflammatory periodontal disorders which are caused by bacterial plaque and normally run the acute course. They’re classified as periodontitis, stomatitis or necrotizing gingivitis, and appear to represent different stages of similar disease. An expert Kings Langley dentist explains that the clinical features in the necrotizing periodontitis are characterized by the presence of ulcerated, punchedout and necrotic lesions which can be covered by the pseudomembrane of the necrotic tissue. Ulcerations are very painful and show the spontaneous bleeding. The important feature of necrotizing periodontal disease is the severe and rapid loss of alveolar bone and clinical attachment within few days or even some few weeks. Other probable clinical features are the presence of adenopathies, general discomfort, oral halitosis, and fever.
In developing countries, prevalence of necrotizing periodontal diseases is much high than in industrialized countries, though, the prevalence of the diseases has dropped considerably during the 20th century. This disease frequently happens in young adults and children, military persons and more to those who are HIV-infected. The prevalence of necrotizing periodontal appears low and also decreases with age. The occurrence in the healthy population is very difficult to estimate due to many studies of the necrotic oral lesions which have failed to distinguish between necrotizing periodontitis and necrotizing gingivitis based on the absence or presence of bone loss and attachment loss at affected regions. Nonetheless, in the HIV-seropositive individuals, prevalence of necrotizing periodontal disease was between 2% and 6%. The low prevalence can be explained by an introduction of antiretroviral therapy that makes no difference between the general population and the patient’s category.
Factors causing necrotizing periodontal disease are not established clearly. It can be the consequence of the necrotizing ulcerative gingivitis. However, the combination of the etiological factors can play the role in the pathogenesis like HIV, diabetes, poor oral hygiene, leukemia, prolonged and intense psychological stress with inadequate recent and rest illness, alcohol abuse, smoking, and nutritional deficiency.
