Capacidade seladora de remanescente de obturação do canal radicular frente a indicadores microbianos

Resumo

This work aimed to evaluate the sealing ability of root canal filling re- mnants (4, 5 and 6mm), employing Sealapex and EndoFill, by means of differents microbial indicators. A platform was employed, which was split in two halves: an upper chamber – where the microbial suspension (containing E. faecalis + S. aureus + P. aeruginosa + B. subtilis + C. albicans); and a lower chamber containing the culture medium Brain Heart Infu- sion, in which 3 mm of the apical region of teeth were kept immersed. Interpretations of the time to occur microbial leakage were made daily for 60 days, using the turbidity of the culture medium which is indica- tive of microbial contamination, as a reference. The data obtained were submitted to the Kruskal-Wallis and Mann-Whitney tests. The outco- mes didn’t show any significant difference between the sealers assessed, when the time for microbial leakage was compared, and leakage was noted in all the comparative groups. When the results of the remaining obturation level were compared, between 4 and 5 mm and 5 and 6 mm, no significant differences were found; however, when 4 and 6 mm levels were compared significant differences were noted.
