INTRODUCTION Diseases of the maxillary sinus have been associated with dental roots near the maxillary sinus that have undergone endodontic treatment. OBJECTIVE To investigate the presence of filamentous fungi in patients with dental roots near the maxillary sinus who had apical periodontitis treated endodontically, and to alert practitioners that this could be a possible avenue of contaminat...

21 Samples from infected root canals of 43 teeth with chronic apical periodontitis 22 were analyzed for the presence and relative levels of 83 oral bacterial 23 species/phylotypes using a reverse-capture checkerboard hybridization assay. 24 Associations between the most frequently detected taxa were also recorded. The 25 most prevalent taxa were Olsenella uli (74%), Eikenella corrodens (63%), 2...

The purpose of this study was to determine how accurately periodontal probes measure connective tissue attachment levels in beagle dogs with (1) clinically healthy gingivae, (2) experimental gingivitis, and (3) periodontitis. In the healthy and experimental gingivitis specimens the probes were inserted with a standardized force of 25 ponds. In periodontitis specimens the probes were inserted wi...
