| pyogenic arthritis caused by capnocytophaga gingivalis in an immunocompetent three-year-old male. | capnocytophaga gingivalis is most often isolated as normal oral flora or with periodontal disease. this organism is also associated with sepsis usually in immunocompromised hosts. we identified pyogenic arthritis caused by c. gingivalis in a 3-year-old immunocompetent male, whose clinical course closely resembled monoarticular onset pauciarticular juvenile rheumatoid arthritis. this is the first report of c. gingivalis septic arthritis in the world literature, but there are increasing reports of ... | 2001 | 17039147 |
| antimicrobial effect of acidified nitrate and nitrite on six common oral pathogens in vitro. | salivary nitrate is positively correlated with plasma nitrate and its level is 9 times the plasma level after nitrate loading. nitrate in saliva is known to be reduced to nitrite by oral bacteria. nitrate and nitrite levels in saliva are 3 - 5 times those in serum in physiological conditions respectively in our previous study. the biological functions of high salivary nitrate and nitrite are still not well understood. the aim of this in vitro study was to investigate the antimicrobial effects of ... | 2006 | 17134590 |
| caries-related plaque microcosm biofilms developed in microplates. | in vivo dental plaque biofilms consist of complex communities of oral bacteria that are a challenge to replicate in vitro. the aim of this investigation was to establish human dental plaque microcosms in microplates to reflect conditions that are relevant to dental caries. microcosm plaque biofilms were initiated from the saliva of two different donors, grown for up to 10 days in 24-welled microplates on thermanox coverslips in various types of artificial saliva with and without sucrose, which w ... | 2007 | 17311629 |
| false positive pcr detection of tropheryma whipplei in the saliva of healthy people. | tropheryma whipplei, the agent of whipple's disease (wd), has been recently isolated and the genomes of two isolates have been fully sequenced. previous diagnosis tools for the diagnosis of the disease used sequence analysis of the 16s rrna gene. using this target gene, the high percentage of detection of the bacterium in saliva of healthy people was in contrast to the negative results obtained with specific target genes. the aim of our study was to compare previously published primers targeting ... | 2007 | 17535423 |

| factors affecting human supragingival biofilm composition. ii. tooth position. | little is known regarding the factors that affect the microbial composition of supragingival biofilms. this study was designed to test the hypothesis that tooth location affects the microbial composition of supragingival plaque beyond the effect due to plaque mass as reflected by total dna probe count. | 2009 | 18973539 |
| bacterial 16s sequence analysis of severe caries in young permanent teeth. | previous studies have confirmed the association of the acid producers streptococcus mutans and lactobacillus spp. with childhood caries, but they also suggested these microorganisms are not sufficient to explain all cases of caries. in addition, health-associated bacterial community profiles are not well understood, including the importance of base production and acid catabolism in ph homeostasis. the bacterial community composition in health and in severe caries of the young permanent dentition ... | 2010 | 20826648 |
| clonal analysis of the microbiota of severe early childhood caries. | severe early childhood caries is a microbial infection that severely compromises the dentition of young children. the aim of this study was to characterize the microbiota of severe early childhood caries. | 2010 | 20861633 |
| bacterial diversity of periodontal and implant-related sites detected by the dna checkerboard method. | the aim of this study was to compare the microbial composition of the subgingival biofilm from teeth and implant sulci in relation to contents originating from internal parts of the implant, abutment and implant prosthesis. twenty subgingival biofilm samples from the mesial and distal aspects of each tooth/implant and 29 samples from the internal parts of titanium implants, abutments and implant prostheses were evaluated for the presence of 18 bacterial species using dna checkerboard and the dif ... | 2011 | 21533621 |
| the role of bacteria in oral cancer. | despite the widening interest in the possible association between bacteria and different stages of cancer development, our knowledge in its relation to oral cancers remains inadequate. the aim of this review article is to derive a better understanding on the role of various micro-organisms in the etiogenesis of oral cancers through all the available data on the pubmed. different bacteria have been proposed to induce carcinogenesis either through induction of chronic inflammation or by interferen ... | 2010 | 21584217 |
| in vitro evaluation of bacterial leakage along the implant-abutment interface of an external-hex implant after saliva incubation. | the aim of this in vitro study was to evaluate bacterial leakage along the implant-abutment interface under unloaded conditions. twelve premachined abutments with plastic sleeves and 12 dental implants were used in this study. prior to tests of bacterial leakage, samples from the inner parts of the implants were collected with sterile microbrushes to serve as negative controls for contamination. after casting, the abutments were tightened to 32 ncm on the implants. the assemblies were immersed i ... | 2011 | 21841988 |
| Early microbial succession in redeveloping dental biofilms in periodontal health and disease. | Teles FR, Teles RP, Uzel NG, Song XQ, Torresyap G, Socransky SS, Haffajee AD. Early microbial succession in redeveloping dental biofilms in periodontal health and disease. J Periodont Res 2011; doi: 10.1111/j.1600-0765.2011.01409.x. © 2011 John Wiley & Sons A/S Background and Objective: The development of dental biofilms after professional plaque removal is very rapid. However, it is not clear whether most bacterial species return at similar rates in periodontally healthy and periodontitis subj ... | 2011 | 21895662 |
| bacterial leakage along the implant-abutment interface: culture and dna checkerboard hybridization analyses. | objective: bacterial species have been found harboring the internal surface of dental implants as consequence of their failed connections. the aim of the present study was to compare the detection frequency of bacterial leakage from human saliva through the implant-abutment interface, under non-loading conditions, using either dna checkerboard or culture method. materials and methods: thirty dental implants with hexagonal platforms were connected to pre-machined abutments according to the manufa ... | 2011 | 22092990 |
| discrimination based on gly and arg/ser at position 673 between dipeptidyl-peptidase (dpp) 7 and dpp11, widely distributed dpps in pathogenic and environmental gram-negative bacteria. | porphyromonas gingivalis, an asaccharolytic gram-negative rod-shaped bacterium, expresses the novel asp/glu-specific dipeptidyl-peptidase (dpp) 11 (ohara-nemoto, y. et al. (2011) j. biol. chem. 286, 38115-38127), which has been categorized as a member of the s46/dpp7 family that is preferential for hydrophobic residues at the p1 position. from that finding, 129 gene products constituting five clusters from the phylum bacteroidetes have been newly annotated to either dpp7 or dpp11, whereas the re ... | 2013 | 23246913 |
