Factors associated with endodontic treatment failures. Bacteroides endodontalis and others black-pigmented Bacteroides species in odontogenic abscesses. Taxonomy, biology, and periodontal aspects of Fusobacterium nucleatum. Bacteria in the apical root canal of teeth with primary apical periodontitis. Culture and molecular biology technologies have demonstrated that the endodontic bacterial communities vary in species richness and abundance depending on the different types of infection and different forms of apical periodontitis. Herpesviruses in abscesses and cellulitis of endodontic origin.

Interpretation of the community behavior can be inferred by global gene expression transcriptomics or by comprehensive inventories of released proteins proteomics and metabolites metabolomics. Molecular identification of microorganisms from endodontic infections. Microbial diversity in endodontic infections has been consistently assessed by anaerobic culturing and culture-independent molecular biology methods. Association of Enterococcus faecalis with different forms of periradicular diseases. Overall, the bacterial density per canal varies from 10 3 to 10 8 2 , 29 , 39 —

Table 1 Distinctive features of the microbiota associated with different types of endodontic infections. Apical periodontitis lesions usually represent an effective immunological barrier periodonhitis spread of the infection from the root canal to the alveolar bone and other body sites.

The fact that E. Information provided by these methods has the potential to disclose patterns of molecules associated with diverse clinical conditions, helping establish outcome predictors based not only in specific species combinations or communities, but perhaps even more importantly on the resultant products of these consortia.

Distinctive features of the microbiota associated with different forms of apical periodontitis

Therefore, there is a current trend to include apical periodontitis in the group of human infectious diseases caused by bacterial biofilms. Abstract Microorganisms infecting the dental root canal system play an unequivocal role as causative agents of apical periodontitis. Bacteria colonizing the root canal are usually organized in communities similar to apicak structures. Prevalence of yeasts in saliva and root canals of teeth associated with apical periodontitis.

Pseudoramibacter alactolyticus in primary endodontic infections. Acute apical periodontitis and abscesses Acute apical periodontitis and acute apical abscesses are typical acute forms of apical periodontitis.

Secondary infections are caused by microorganisms that were not present in the primary infection, but that were introduced in the root canal at some time after professional intervention.

Molecular identification and quantification of bacteria from endodontic infections using real-time polymerase chain reaction. Enteric rods Olsenella spp. Therefore, it is a challenge for researchers to apply sophisticated technology to identify community patterns related to geography and establish whether or not treatment protocols should be disseftation accordingly.

The Association of Statin Intake and Healing of Apical Periodontitis After Root Canal Treatment

Microbial flora of root canal-treated teeth associated with asymptomatic periapical radiolucent lesions. Therefore, specificity in causation of apical periodontitis appears to dssertation stronger at the community level. Molecular detection and identification of Synergistes phylotypes in primary endodontic infections.

Herpesviruses in endodontic pathoses: Microbiologic analysis of teeth with failed endodontic treatment and the outcome of conservative re-treatment. Therefore, the acute abscess can be regarded as an advanced stage of the acute disease. Most of the cultivable named species found in extraradicular infections possess an array of virulence traits that may allow them to avoid or circumvent the host defenses in the inflamed periradicular tissues — Bacterial community profiles in treated cases vary from individual to individual, suggesting that distinct bacterial combinations can play a role in treatment failures Molecular analysis of endodontic infections.
