OLIVEIRA, Milene de et al. Evaluation of bacterial contamination in composite resins used at graduation clinics of FO-UFJF. Odontol. Clín.-Cient. (Online) [online]. 2010, vol.9, n.1, pp. 73-76. ISSN 1677-3888.

OBECTIVE: evaluate the bacterial contamination in composite resins used daily at graduation clinical of FO/UFJF. METHODS: for detection of bacterial growth on culture of samples from 50 tubes of composite resin, and 25 Charisma^® (Heraeus-Kulzer) and 25 Durafill^® (Heraeus-Kulzer). Two new tubes of each brand served as the control group and the other tubes of composite resin used in the study were in use in clinical studies, forming the test group. The collection of samples was performed with aseptic technique in the chapel of laminar flow, using previously sterilized toothpicks. After collecting the material and inoculum in the culture medium, the evaluation systems were maintained in bacteriological incubator at 37 ºC. RESULTS: after 24 hours of incubation, observed the turbidity of the culture medium in only 2 test tubes of test group. The results were submitted to Pearson's Chi Square, not showing statistically significant results (p> 0.005). CONCLUSION: the composite resins used in the FO/UFJF were not contaminated and it is believed that the technical maintenance of the aseptic chain employed in clinical studies of the institution were effective, but may not be the only ones responsible for not contamination.
