RESUMO
The periodontal infection is a reserve of gram-negative anaerobic microrganisms, lipopolysaccharidaes and inflammatory mediators like the PGE2 and the TNF-?. These mediators also act in the childbirth. The aim of this study was to evaluate, in female rats, the relationship between the induced periodontal disease and your effects on pregnancy. To this, Wistar rats were divided in three groups: the pregnancy group (PR) (n=16); the pregnancy + periodontal disease group (PRDP) (n=21) and the periodontal disease group (DP) (n=09). The induction of the periodontal disease was made by cotton ligatures around 06 molar teeth, 60 days before the reproduction induction. Additionally, the adult females were sacrificed after the births of offsprings to analyse the evolution of the periodontal disease between the different groups of research, through histometric of furcation area of the first molars inferiors. On histometric procedure, both groups with induced periodontal disease showed a increased bone loss when compared with no-disease group (PRDP: 191,6 ± 72,99; DP: 148,7 ± 44,37; PR: 53,05 ± 12,86; p<0.0001). It was not found difference between groups with relation to pregnancy time (PR: 23,12 ± 0,88; PRDP: 22,61 ± 0,86 days). It was not found differences between the average of the weight of livings puppies between groups (PR: 6,20g ± 0,48; PRDP: 6,10g ± 0,44; p=0.5404). It was identified significance statistic between stillborn puppies of healthful rats (PR: 6,34g ± 0,41) and sick rats (PRDP: 4,96 ± 0,52; p=0.0062). In agreement with this study, the experimental periodontal disease in rats could be associated with the embryolethality and fetal growth restriction
