Similarities of periodontal clinical and microbiological parameters in mother-child pairs / Similaridades da clinica periodontal e parametros microbiológicos em pares mãe-filho

The aim of this study was to verify the association between children and their mothers (N=28) for periodontal clinical and microbiological measures. Periodontal clinical parameters (probing depth and bleeding on probing) were obtained from six reference teeth from each mother-child pair. In addition, subgingival plaque samples taken from the same reference teeth were collected and placed on the Perioscan test for the detection of Treponema denticola, Porphyromonas gingivalis and Bacteroides forsythus. There were statistically significant differences between children and mothers regarding probing depth; there was an overall tendency for mothers to exhibit average probing depths greater than their children. In contrast, if a child had a bleeding site, the respective site on the mother usually also bled on probing, implying that there was an association in terms of bleeding between the mother-child pairs. Similar findings were observed for the Perioscan test. It is concluded that the occurrence of bleeding and periodontal anaerobic infections (as determined by the Perioscan test)were similar in reference teeth of mother-child pairs. These data suggest that parents with periodontal disease may serve as a reservoir of periodontopathic organisms for their children

Periodontite prépuberal generalizada / Generalized prepuberal periodontitis

É relatado um caso de periodontite pré-puberal generalizada em um menino de cinco anos de idade. Em relaçäo a todos os dentes decíduos remanescentes, foi encontrada retraçäo gengival sem inflamaçäo e reabsorçäo acentuada de osso alveolar. Näo foram relatados problemas respiratórios ou infecçöes frequentes. Exames laboratoriais revelaram valores normais para sangue e urina e os testes genéticos confirmaram o diagnóstico

Aplicação da estereoscopia em periodontia / Stereoscopic roentgenology in periodontal diseases

Os autores analisam a viabilidade da aplicação do método estereoscópico em Periodontia, comparando as imagens por essa técnica, com a situação real de reabsorção óssea periodontal em pacientes, observada por abertura cirúrgica
