Influência da doença periodontal no parto pré-termo e nascimento de bebês de baixo peso

Abstract

Influence of the periodontal disease in childbirth preterm and babies of low weight birth. The disease periodontal, of high prevalence in the human being, is an infect-inflammatory disease caused by the interaction of the pathogens present periodontal in the dental biofilm with the mechanisms of answer of the host. This interaction is responsible for the periodontal destruction and mediated by chemical substances as: cytokines, prostaglandins, proteins of the system complement and other plasmatics proteases. The periodontum-pathogenics microrganisms, besides causing damages local tissues, can unchain a bacteremia, taking to significant anatomicophysiological alterations in other organs and tissues. Studies suggest an association between the disease maternal periodontal and the premature birth occurrence and babies of low weight to the birth, due to the action direct or indirect of microrganisms and chemical mediators, in the fetus-placental unit, taking to the alterations in the evolution of this physiologic period.
