ABSTRACT
The aim of this study was to determine the frequency of isolation of Actinobacillus actinomycetemcomitans (Aa) in 100 patients with chronic periodontitis, 14 patients with aggressive periodontitis, 142 pre-school children with gingivitis and 134 periodontally healthy subjects. Samples of subgingival plaque were taken using sterilized paper points introduced into periodontal pockets or gingival crevice for 60 seconds and inoculated on TSBV agar, which was incubated under anaerobiosis at 37°C, for 4 days. Microbial identification was performed through biochemical methods and morphocellular and morphocolonial analysis. Aa was detected in 40.3 percent of healthy subjects, 68 percent of patients with chronic periodontitis, 92.86 percent of patients with aggressive periodontitis and 40.14 percent of children with gingivitis. The rate of recovery of Aa in the tested human groups proved to be higher than previously reported and in agreement with participation of this facultative anaerobe as a member of native microbiota of the periodontium and its relation with aggressive and chronic periodontitis in Brazil.
RESUMO
Avaliou-se a ocorrência de Actinobacillus actinmycetemcomitans (Aa) em pacientes 100 pacientes com periodontite crônica, 14 com doença periodontal agressiva, 142 crianças com gengivite em idade pré-escolar e 134 indivíduos adultos saudáveis. Amostras de placa subgengival foram coletadas usando cones de papel estéreis introduzidos nas bolsas periodontais ou no sulco gengival por 60 segundos e inoculadas em ágar TSBV, que foram incubadas em anaerobiose a 37°C, por 4 dias. A identificação microbiana foi realizada através de análises bioquímicas, morfocelulares e morfocoloniais. Aa foi detectado em 40,3 por cento de indivíduos saudáveis, 68 por cento de pacientes com periodontite crônica, 92,86 por cento de pacientes com periodontite agressiva e 40,14 por cento das crianças com gengivite. A taxa de ocorrência de Aa nos grupos testados provou ser mais alta do que a previamente descrita na literatura e que esse microrganismo é membro freqüente da microbiota de indivíduos adultos periodontalmente sadios e de crianças com idade pré-escolar com gengivite além de sua relação com a periodontite crônica e agressiva no Brasil.
