Which of the following pathogens is strongly associated with periodontal disease?

What pathogens cause periodontal disease?

High-risk periodontal pathogens include Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td) and Fusobacterium nucleatum (Fn). They are prevalent in periodontitis.

What is periodontal pathogenic bacteria?

From Wikipedia, the free encyclopedia. Well studied Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis. Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses.

What periodontal pathogen is most frequently associated with localized aggressive periodontitis?

For decades, Aggregatibacter actinomycetemcomitans has been considered the most likely etiologic agent in aggressive periodontitis.

Which bacterial characteristics is associated with periodontal health?

Microbiota in different periodontal diseases

the bacterial flora associated with healthy periodontal tissue contains mainly Gram-positive microorganisms with a dominance of Actinomyces and Streptococcus spp. Gram- negative species and spirochetes may be also present in healthy patients, although in low concentration.

What is putative periodontal pathogenic bacteria?

Periodontitis is a multi-microbial oral infection with high prevalence among adults. Putative oral pathogens are commonly found in periodontally diseased individuals. However, these organisms can be also detected in the oral cavity of healthy subjects.

What is the keystone pathogen in periodontitis?

gingivalis impairs innate immunity in ways that alter the growth and development of the entire biofilm, triggering a destructive change in the normally homeostatic host-microbial interplay in the periodontium. In other words, P. gingivalis could be a keystone pathogen of the disease-provoking periodontal microbiota.

Which bacterial species is not predominantly associated with periodontitis?

The saliva-dominated subgroup was characterized by high levels of bacteria that are not generally associated with periodontitis. Presumably some of these genera, such as Streptococcus, Neisseria, Veillonella, Actinomyces, Rothia, and Prevotella, were saliva-enriched bacteria (Fig.

What bacteria causes aggressive periodontitis?

Localized aggressive periodontitis is mainly associated with the bacteria Aggregatibacter actinomycetemcomitans(41,42), while generalized aggressive periodontitis is strongly associated with specific bacteria such as Porphyromonas gingivalis, Tannerella forsythia(43,44) and Aggregatibacter actinomycetemcomitans, Gram- …

What is localized aggressive periodontitis?

Localized Aggressive Periodontitis (LAP) is a rare form of inflammatory periodontal disease characterized by a rapid rate of progression, dramatic attachment and bone loss, on very specific teeth (first molars and incisors), and an early age of onset1,2.

What is aggressive periodontal disease?

Abstract. Aggressive periodontitis is a destructive disease characterized by the following: the involvement of multiple teeth with a distinctive pattern of periodontal tissue loss; a high rate of disease progression; an early age of onset; and the absence of systemic diseases.

Is aggressive periodontitis common?

According to the 1999 International Workshop for the Classification of Periodontal Diseases, aggressive periodontitis was defined according to 3 primary features, in contrast to chronic periodontitis. These features are common for both localized and generalized form of disease.

Which of the following bacteria is most important in causing periodontal diseases?

Etiology. Streptococcus mutans is the main cause of dental decay. Various lactobacilli are associated with progression of the lesion.

What are the microorganisms which are predominant in the occurrence of dental caries?

Microorganisms associated with tooth decay

Streptococcus mutans and Streptococcus sobrinus are the principal agents of enamel caries [6,41-44]. Lactobacillus and Actinomyces are also associated with caries.
