CURRENT SUSPECTED PERIODONTAL PATHOGENS

1. Introduction to periodontal Pathogens

A. despite more than 500 species of bacteria were isolated from the periodontal pockets, it is likely that only a small percentage of these bacteria periodontal pathogens.

B. several microorganisms were strongly associated with chronic periodontitis [5]. Refer to table 6-1 list of suspects periodontal pathogens. Future research will likely identify additional periodontal pathogens.

C. in the future, dentists can perform diagnostic tests and treatments are aimed specifically at these periodontal pathogens.

2. Periodontal Pathogens. The world's workshop in Periodontology (consensus report, 1996) designated A. actinomycetemcomitans, P. gingivalis, and so forsythia, as periodontal pathogens (table. 6-2) [6].

A. Aggregatibacter actinomycetemcomitans

1. This species was recently renamed Aggregatibacter actinomycetemcomitans from its former name Actinobacillus actinomycetemcomitans [7].

2. This microorganism has been strongly associated with aggressive periodontitis [8-10].

3. Aggregatibacter actinomycetemcomitans also been implicated in cases of chronic periodontitis, but less and less often and in smaller quantities than from defeat in aggressive periodontitis [11,12].

4. Aggregatibacter actinomycetemcomitans able deviation from normal of the host immune response and destruction of connective tissue in the gums and the bone (Fig. 6-7).

B. Tannerella forsythia

1. This species was renamed so forsythia from her former name Bacteroides forsythus [13].

2. The role of the so forsythia at illnesses of parodont been explained numerous studies involving DNA-probes or immunological methods.

3. The researcher of this YEAR the Grossi and colleagues believe, so forsythia to be the most important microbial risk factor that distinguishes subjects with periodontal disease from those who periodontally health [14,15]. 4. So forsythia the most common species found on or in the epithelial cells recovered from periodontal pockets [16].

5. The risk of periodontal attachment loss is higher in adolescents who colonized so forsythia than in those in which the species is not found [17]...
