PART 6: CROSS INFECTION AND CONTROL. The study was conducted from December 2013 to May 2014 at Ewha Womans University Mokdong Hospital, Seoul, Korea. Four different implant-abutment connections were studied: external hexagon (control group), double internal hexagon (test group 1), internal hexagon with external collar (test group 2), and conical connection (test group 3). Besides pathogenic microorganisms, genetic and environmental factors contribute to the development of this disease. Any substantial or systematic, reproduction, redistribution, reselling, loan, sub-licensing, systematic supply, www.tandfonline.com/page/terms-and-conditions, It has been demonstrated, however, that the initiation and, susceptible host (3, 8, 14, 15, 24, 28). Within the limits of this study, the authors found that the levels of four significant bacterial strains were decreased in both hypofunctional healthy and hypofunctional periodontitis groups compared to normofunctional equivalents. Though not evaluated in this study, this situation could be due to periodontal ligament atrophy and related physiological alterations. Digestive System. A subject was considered to exhibit additional attachment loss if one or more sites increased 3 mm or more in a probing attachment level measurement in one year. Although results relate to the presence of certain periodontopathogens with fixed periodontal status, there is still no convincing evidence for the specificity of bacterial species in different periodontal diseases (12, 26). Two samples from the apical portion of periodontosis lesions and one sample from clinically normal sites were taken from each patient.

These include the modulation of physicochemical properties such as periodic topographies, roughness, surface free energy, or hardness. The detection frequency of the investigated periopathogens was statistically insignificant higher with the sampling method MT6 compared with MT4. The ELISA and reagent card were comparable in their ability to distinguish between clinically healthy and diseased sites. The microora associated with necrotic-, ulcerative gingivitis and periodontitis contains Gram-negative, perform both qualitative and quantitative determination of, In addition, prediction of the disease progression would allow. Dentoalveolar and endodontic infections. The aim of this study was to evaluate dental plaque compositions, vascular endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF) 1-alpha levels in gingival crevicular fluid (GCF) at hypofunctional and normofunctional teeth in healthy individuals and chronic periodontitis patients. P. gingivalis fortified the growth of the other two to establish polymicrobial biofilms in a synergistic manner. elimination, immune response and virulent factors (6). Test groups 2 and 3 had significantly lower total bacterial counts in the peri-implant sulcus and inside the connection. Microbiology of destructive periodontal disease in adolescent patients with congenital neutropenia - A report of 3 cases . Comparable information could be obtained when the same plaques were evaluated by the reagent card format for BANA hydrolysis. SP was also effective against anaerobes implicated in periodontal diseases, and their tannin content reduced clinically visible gingivitis. Introduction to the Microbiology of Periodontal Disease The bacteria involved in causing periodontal disease are numerous, with associations with over 400 bacterial species in a pocket! Periodontal diseases lead to damage of the periodontal tissues supporting the teeth (bone and connective tissue) … Set alert. MICROBIOLOGY OF PERIODONTAL DISEASES… of host-cell collagenase inhibitors), collagenase, hemolysin. The research on the microbiology of periodontal health and diseases has been the focus of intense investigation for several decades. The aim of the present project is to investigate the fillings’ repairs as part of minimally invasive treatment of dental caries. The presence or absence of AA could be evaluated in 11 papers. 1987 Sep;22(5):335-41. doi: 10.1111/j.1600-0765.1987.tb01595.x. The association of coronary heart disease and periodontal disease may be due to an underlying response trait, which places an individual The purpose of the present investigation was to attempt to define such communities using data from large numbers of plaque samples and different clustering and ordination techniques. Abstract Aim: Herbal products are increasingly used as therapeutic agents in the prevention and management of periodontal diseases to preclude the side effects of antibiotics. Other microorganisms that have been implicated as predominant species in the disease process are: Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus, Peptostreptococcus migros, Eikenella corrodens. The results indicated that samples obtained from pocket sites consisted of significantly increased proportions of Gram negative anaerobic rods when compared to a predominantly Gram positive flora in the control sites. The same pocket was sampled at baseline and after 6 months of orthodontic treatment for the frequency of positive detection of Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Prevotella intermedia (Pi), Tanerella forsythia (Tf), Treponema denticola (Td). found for many microorganisms of the dental biolm, the Gram-negative bacteria relatively to the Gram-positive, corresponds to physiologic changes in the, species exist in the form of antagonism (. Conclusion: Chitosan from Haruan fish scales proved to have antioxidant activity.Keywords: Antioxidants, Chitosan, Haruan fish scalesABSTRACTBackground: Stimulation of inflammatory cells such as polymorphonuclear cells (PMN) will initiate to release free radicals in destroying bacteria. SUMMARY Periodontal disease is perhaps the most common chronic infection in adults. J Periodontol. The content of each vial was analyzed with nucleic-acid based methods for Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Porphyromonas gingivalis, Treponema denticola, Prevotella intermedia, Parvimonas micra, Fusobacterium nucleatum, Campylobacter rectus, Eubacterium nodatum, Eikenella corrodens, and Capnocytophaga sp. The presence and levels of 40 subgingival taxa were determined in 13,261 plaque samples using whole genomic DNA probes and checkerboard DNA-DNA hybridization. 34. Socransky SS. Results: The results showed that chitosan from Haruan fish scales have antioxidant activity with 50.513% percentage of inhibition at a maximum concentration of 350 ppm with an IC50 value of 356.98 ppm. Principles of infection control. The frequency of detection of Aa, Pg, Pi, and Tf was not significantly different between baseline and 6 months of treatment, while a marginally significant increase of Td was found. Chitosan from Haruan scales in addition to being antimicrobial turned out to also be antioxidants. Results: Mean participant age(SD) was 68.9(8.7). periodontal diseases DR PO AYANBADEJO Faculty of Dental Sciences CMUL. 1. Microbiology of periodontal disease. 5 major complexes were consistently observed using any of the analytical methods. Test group 3 presented the lowest mean values for red complex bacteria and control group the highest, although differences were non-significant. of the whole biolm when these microorganisms are present. Periodontal diseases can be defined as disorders of supporting structures of the teeth, including the gingivae, periodontal ligament and supporting alveolar bone. J Periodontal Res. There were no significant differences in the clinical parameters or microflora in the initial phase of orthodontic treatment in patients with reduced periodontal support. Oral microbiome and the oral ecosystem. The response variables were percentage of positive sites and absolute bacterial load. least two healthy implants functionally loaded for 5 years. Sensitivity and specificity of every microbiological test were individually calculated for each selected study, assuming that the clinical diagnosis of AgP or ChP was the true status the tests attempted to detect. causes degradation of the periodontium, resulting in tissue destruction. A light and electron microscopic study. The relationship between periodontal diseases and diabetes: an overview. There was also a decrease in Eikenella corrodens levels in hypofunctional periodontitis group (P<0.05). Dental plaque mediated periodontal disease. Furthermore, it was carved out which strategies were developed in dental research and general surface science to inhibit bacterial colonization and to delay biofilm formation by low-fouling or “easy-to-clean” surfaces. Evidence has been accumulating for the past 30 years which indicates that almost all forms of periodontal disease are chronic but specific bacterial infections due to the overgrowth in the dental plaque of a finite number of mostly anaerobic species such as Porphyromonas … Clinic for Periodontology and Oral Medicine, School of Dental Medicine, University of Belgrade, Belgrade, Serbia. nov., is suggested. 38. The three types of red complex pathogens were simultaneously detected in the same gingival fluid sample. LAMP method was of a significant value for perfect rapid identification of the target species of extracted DNA or intact cells within half an hour. One cornerstone of this evolution has been the increased understanding of the microbiology characterizing health and disease of the periodontium. The role of natural devices such as chewing sticks with a pedigree of good oral hygiene and antimicrobial activities in oral health therapy is apt. Learning Outcomes • Describe the development of supragingival and subgingival plaque biofilms. Nowadays, there is a high prevalence of periodontal disease worldwide, and knowing the etiology is basic for its control. Colonization and inflammation of the subgingival pocket and the gingival crevice does not necessarily lead to the development of periodontitis, but rather to a change in environmental conditions, followed by an ecological shift toward Gram-negative and proteolytic bacteria that trigger immunological reactions that can lead to the clinical signs of periodontitis [12. Introduction to the Microbiology of Periodontal Disease. Further, Gram-negative anaerobic species have been documented as primarily etiological agents involved in periodontal disease.

A comparison between Spain and The Netherlands. ROC diagrams indicated the limited discriminatory ability of all of the test parameters to identify subjects with AgP. The deep pocket microflora in juvenile periodontitis was also made up mainly of Gram-negative organisms (about 65%), but was of a nature different from that of adult periodontitis, being predominated by isolates of Bacteroides species and other organisms of unknown species.The present article also concerns factors of importance for the colonization of Gram-negative anaerobic rods in the oral cavity and periodontal pockets. Periodontal Disease. Chitosan from Haruan scales in addition to being antimicrobial turned out to also be antioxidants. Mean adjusted c-IMT across quintiles of the etiological titer-to-colonization ratio were QI=0.869, QII=0.867, Q3=0.849, Q4=0.854, Q5=0.836mm (p for trend=0.002). The association of bacteroides gingivalis, Bacteroides forsythus, Treponema denticola, and Actinobacillus actinomycetemcomitans among others with periodontal disease offers the opportunity for the development of diagnostic tests that are based upon the detection and/or quantification of one or more of these organisms or their by-products in the plaque.
