Presents a modern understanding of the role of periodontophatogenic bacteria types: Aggregatibacter actinomycetemcomitans (Actinobacillus actinomycetemcomitans), Tannerella forsythia (Bacteroides forsythus) and Porphyromonas gingivalis as indicators of periodontitis emergence and development risk. Therminological definitions are given of factors, indicators and markers of risk of periodontium inflammatory diseases development that show the level of importance of their association with the disease as well as the quantitative evaluation of these associations.

AbstractThree bacterial species pertaining to the red complex (Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia) and Aggregatibacter actinomycetemcomitans were investigated in relation to the incidence and severity of periodontal disease. A total of 259 patients were included in this study, 179 being diagnosed with periodontal disease. The gingival crevicular fluid samples were obtained from periodontal pockets and the presence and levels of target bacteria were assessed following DNA extraction and real-time quantitative PCR. Our results account for significant positive associations between the number of bacterial species from the red complex coexisting within a patient and several clinical signs (gingival bleeding, inflammation and bone deterioration). A similar positive association was found between bacterial load of the red complex species and the clinical Case Type diagnostic of the periodontal disease, as well as the probing depth with the most evident results for T. denticola. In conclusion, our study, a first for the Romanian population, confirms previous results found elsewhere and finds a possible regional pathogenic specificity for T. denticola as a major factor for periodontitis severity.

Aggressive periodontitis(AgP) is a disease characterized by the presence of periodontal pathogens and family aggregation of cases, possibly related to the vertical transmission of microorganisms. Thus, the project has evaluated the pattern of colonization of some pathogens in children of parents affected by generalized aggressive periodontitis, compared to children of periodontally healthy parents. Five edentulous babies and 15 primary, mixed and permanent dentate children from families with parents affected by AgP were selected and, by a age and gender-matched approach, similar population from eriodontally heath individuals were also selected. From all subjects, saliva was collected, had a DNA extracted and sequenced for Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Treponema denticola (Td), Tannerella forsythia (Tf) identification. Results showed a higher prevalence in AgP-family children regarding Td and Tf. denticola in mixed and permanent dentition (p<0.05). In conclusion,the presence of disease in parentes negatively affectthe oral microbiota of their descendants.
