Purpose/Objectives: To investigate causative organisms in periapical osteitis, in particular the presence of anaerobic bacteria.

Materials & Methods: 27 patients with 32 single rooted teeth that were free of caries and restorations but that were necrotic due to trauma were sampled. 18 teeth with radiographic evidence of periapical osteitis were also sampled. Samples were taken with extra care to preserve anaerobic microorganisms as well as to preserve the integrity of the sample.

Results: o 88 strains were isolated o Only 5 of 88 strains grew in air o Commonly found bacteria – Fusobacterium, Bacteroides, Eubacterium, Peptococcus, Peptostreptococcus, and Campylobactor.

Author’s Conclusion: Necrotic pulps contain a large, varying amount of bacteria with a strong propensity to select for anaerobic microorganisms.

Validity of Conclusion: Conclusion is valid but not well summarized.

Reviewer’s Comments: No mention of the comparison between the test groups. No mention of correlations between several other statistics that were recorded.
