Abstract Background and objectives: Anaerobic microorganisms, particularly bacteroides play an important role in causing Pulp and preapical diseases that lead to chronic abscess. we aimed at studying anaerobie infections in necrotic teeth having Acute and chronic clinical symptoms. Material and Methods: We examined 28 necrotic teeth of 28 patients for the purpose of anaerobic culture fifteen cases with acute clinical symptoms and 13 ones with chronic clinical symptoms. In total 38 root canals from 28 teeth were subjected for examination and sampling. The samples were cultured on thioglycolate medium, sent to laboratory and tested in anaerobic condition for identification of bacteria. Results: The results indicate that 76% of isolated bacteria from necrotic canals obligate anaerobes and 24% are facultative anaerobes. The most common isolated microorganisms are peptostreptococci, fusobacterium and bacteroides. Conclusion: These results are in agreement with the results of other researchers and it has been determined that bacteroids play an important role in destroying the necrotic teeth's bone. Anaerobic bacteria causing dental infactions are less identified and diagnosed, therefore, dentist and clinical lab should take this into account. Key words: Anaerobic Bacteria, Necrotic tooth, Pulp, preapical

Clinical Significance of Anaerobic Infections

Anaerobic infections usually occur when an anatomical barrier becomes disrupted and constituents of the local flora enter a site that was previously sterile. Any site in the body is susceptible to infection with these indigenous organisms when a mucosal barrier or the skin is compromised by surgery, trauma, tumor, ischemia, or necrosis, all of which can reduce local tissue redox potentials [1]....

An investigation of the presence of specific anaerobic species in necrotic primary teeth.

Different microbial identification methods have shown that the microbial community profiles in endodontic infections are diverse and assorted. The aim of this study was to evaluate the frequency of selected endodontic pathogens in the pulp chambers (PCs) and root canals (RCs) of infected primary teeth using PCR methods. Paired PC and RC samples were collected from 15 subjects and analyzed by PC...

Reconstruction of nonvital teeth using direct fiber-reinforced composite resin: a pilot clinical study.

PURPOSE To evaluate the clinical performance of direct Class II fiber-reinforced composite restorations on nonvital teeth. MATERIALS AND METHODS Thirty patients age 18 or older were included in this clinical trial restoring 35 molars. The inclusion criteria were: two- to four-surface restorations, replacement of composite and amalgam restorations necessary or unrestored teeth with decay reach...
