The first treatment is 4, 6, 8 and 10 ppm standard ascorbic acid concentration with DPPH solution as positive control, and the second treatment is 200, 250, 300 and 350 ppm chitosan from Haruan scales concentration with DPPH solution. A. actinomycetemcomitans serotype b, Selenomonas noxia and Actinomyces naeslundii genospecies 2 (A. viscosus) were outliers with little relation to each other and the 5 major complexes. Quantitative real-time PCR was carried out for Total Bacterial Count and for 10 microorganisms: Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythensis, Treponema denticola, Prevotella intermedia, Peptostreptococcus micros, Fusobacterium nucleatum, Campylobacter rectus, Eikenella corrodens, and Candida albicans. It is xxxxxx believed xxxxxx xxxxxx xxxxxx condition is left untreated, it xxxxxx quickly xxxxxx to xxxxxx patient losing xxxxxx or her teeth. Only 74 of the 271 subjects (27.3%) exhibited additional attachment loss of 3 mm or more at 1 or more sites after 1 year. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Prevotella intermedia, Fusobacterium nucleatum, Parvimonas micra, Campylobacter rectus, Eikenella corrodens, Streptococcus mutans, and Streptococcus sobrinus levels were detected by a real-time polymerase chain reaction at the same points in time. Further, Gram-negative anaerobic species have been documented as primarily etiological agents involved in periodontal disease. Some features of the site may not work correctly. 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. Conclusion Sigmund S. Socransky. 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. They are derived from a variety of plants containing bioactive agents with fewer side effects than the conventional antimicrobial agents. Periodontal diseases can be defined as disorders of supporting structures of the teeth, including the gingivae, periodontal ligament and supporting alveolar bone. Periodontal disease can be increased by several risk factors such as smoking, systemic diseases, medications such as steroids, antiepileptics, drugs for cancer therapy, poor placement…, MICROBIAL BIODIVERSITY AND ANTIBIOTICS IN PERIODONTAL DISEASES A LITERATURE REVIEW, Treatment of dental polyclinic -induced gingivitis caused by secondary caries: a case report, Antibacterial and anti-adherent effect of Mimosa tenuiflora and Myrciaria cauliflora on dental biofilm bacteria, ASSOCIATION BETWEEN OBESITY AND PERIODONTAL DISEASE AMONG YOUNG AND MIDDLE AGED ADULT GROUPS, Therapeutic effects of antibiotics loaded cellulose nanofiber and κ-carrageenan oligosaccharide composite hydrogels for periodontitis treatment, The potency of Immunoglobulin Y anti Porphyromonas gingivalis to inhibit the adherence ability of Porphyromonas gingivalis on enterocytes, Fabrication and Invitro Characterization of Bioactive Glass / Nano-Hydroxyapatite Reinforced Electrospun PolycaprolactoneComposite Membranes for Periodontal Tissue Engineering, Fabrication and In Vitro Characterization of Bioactive Glass/Nano Hydroxyapatite Reinforced Electrospun Poly(ε-Caprolactone) Composite Membranes for Guided Tissue Regeneration, PENGARUH EKSTRAK FLAVONOID PROPOLIS KELULUT (G.thoracica) TERHADAP JUMLAH SEL NETROFIL PADA PERIODONTITIS (Studi In Vivo Pada Tikus Wistar (Rattus norvegicus) Jantan). Three bacterial burden scores were created by grouping bacterial colonization levels as follows: 1) etiologic (Porphyromonas gingivalis, Tannerella forsythia, Aggregatibacter actinomycetemcomitans, Treponema denticola), 2) putative (Prevotella intermedia, Fusobacterium nucleatum, Micromonas micros, Campylobacter rectus, Eikenella corrodens), and 3) health-associated (Veillonella parvula, Actinomyces naeslundii). The next step is bacterial invasion or invasion by pathogenic products into the periodontal tissues, interactions of bacteria or their substances with host cells, and this directly/indirectly causes degradation of the periodontium, resulting in tissue destruction. No such association was found with putative (p=0.9) or health-associated (p=0.4) bacteria across titer-to-colonization ratios. The 16S rRNA gene sequence BLAST analysis assigned strain SKVG24 to the genus Paraclostridium as it displayed 99.93% identity with P. benzoelyticum JC272T followed by P. bifermentans ATCC 638T (99.79%). Microbiology of Periodontal Diseases. ROC diagrams indicated the limited discriminatory ability of all of the test parameters to identify subjects with AgP. found for many microorganisms of the dental biolm, the Gram-negative bacteria relatively to the Gram-positive, corresponds to physiologic changes in the, species exist in the form of antagonism (. Factors which influence activity include susceptibility of the individual host and the presence of interacting bacterial species which facilitate or impede disease progression. Specific etiologic agents of these diseases have been sought for over 100 years; however, the complexity of the microbiota, an incomplete understanding of the biology of periodontal diseases, and technical problems have handicapped this search. PD may be periodontal diseases 2. mixed infections 3. large # of species present 4. many species are difficult to grow 5. time of sampling may be wrong 6. different sites in patients may have different bacteria (even diff. intermedius, Haemophilus species, and other Gram-negative organisms comprised about 45% of the total gingivitis isolates. Oral mucosal and salivary gland infections. Though not evaluated in this study, this situation could be due to periodontal ligament atrophy and related physiological alterations. The detection frequency of A. actinomycetemcomitans (MT4/MT6) at 22/24 %, T. forsythia at 93/96 %, P. gingivalis at 78/79 %, T. denticola at 88/90 %, P. intermedia at 40/46 %, P. micra at 75/79 %, F. nucleatum at both 99 %, C. rectus at 84/89 %, E. nodatum at 62/65 %, E. corrodens at 80/87 %, and Capnocytophaga sp. Subgingival plaque samples were taken from the mesial aspect of each tooth in 185 subjects (mean age 51 +/- 16 years) with (n = 160) or without (n = 25) periodontitis. Plaque samples were taken.

The detection frequency of the investigated periopathogens was statistically insignificant higher with the sampling method MT6 compared with MT4. These organisms were differentiated into 5 groups based on morphologic, cultural, and biochemical characteristics. Structure of the microbial flora associated with periodontal health and disease in man. The different appearing colonies were purified and identified by Loop-Mediated Isothermal Amplification protocol (LAMP) for the detection of red complex species. 36. Publication details, including instructions for authors and subscription information: Microbiology of Periodontal Diseases. Socransky SS. Log-linear analysis suggested that the association between bleeding on probing, age, or plaque levels with additional attachment loss may be explained by the association of these variables with baseline attachment loss. 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. Streptococcus and facultative and anaerobic Actinomyces species constituted the majority of the Gram-positive gingivitis isolates. the vitality and growth of a pathogen; by enhancing the ability, of the benecial microorganisms can produce anti-periodontal, commonly generalized, and is more severe in individuals with, Suspect periodontopathogens and their association with periodontal diseases, clinical, bacterial composition with a higher level of. 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. 34. The presence or absence of five microorganisms was selected as primary study parameters: Actinobacillus actinomycetemcomitans (AA), Porphyromonas gingivalis (PG), Prevotella intermedia (PI), Bacteroides forsythus (BF), and Campylobacter rectus (CR). They form small transparent … This multi-center study demonstrated that antibodies to B. gingivalis and T. denticola could detect these organisms by an ELISA in the majority of the subgingival plaque samples. Bacteriologic specificity, periodontal disease activity, anatomical plaque research, bacterial recolonization and the concept of bacterial succession are discussed.
