RESUMO

Similar to natural teeth, implants are liable to destruction of support structures. This process of destruction is often the result of opportunistic infections by bacteria that colonizes restorations on the implants and adjacent theeth. A. actinomycetemcomitans is often isolated from periodontal and periimplantar sites but its hole in disease is already to be determined. The aim of this study was to compare the presence of A. actinomycetemcomitans in samples of crevicular fluid and saliva from 14 patients partially and 8 totally edentulous, aging from 42 to 78 years old, rehabilitated with osseointegrated titanium implants, Samples of crevicular fluid were obtained with paper points introduced in periimplantar pockets after removal of supragingival plaque with sterile gauze and left inside for 1 minute. The poits were transferred to tubes with triptic soy solution, homogeneized and plated, in duplicate, on TSBV agar and the plates incubated for 5 days in 37C. After this period, the number of cfu/mL of the microorganism. The presence of A. actinomycetemcomitans was also verified in samples of saliva. The samples were collected with sterile swabs and processed the same way. The results demonstrated that A. actinomycetemcomitans is isolated from gingival fluid and saliva in a small number of patients and in small quantity, both in partially edentulous and totally ones and the differences were not significant between groups (Test Mann-Whitney-gingival fluid: 0.7280; saliva: 0.3503). the results of this study suggest that the colonization of periimplantar sulcus and oral cavity of and the number of mL of A. actinomycetemcomitans in theses sites are not modulated by the presence or not natural theeth.
