Eficácia da barreira intracanal contra ainfiltração microbiana em dentes preparados para pino intrarradicular [Efficacy of intracanal barrier against microbial infiltration in teeth prepared for intraradicular post]
Journal Publication ResearchOnline@JCUAbstract
Introduction: Intraradicular posts are recommended to improve retention of artificial crowns and distribute intraoral forces along the root. If the space created by partial removal of the filling is not filled properly, massive infiltration of microorganisms from the oral cavity can occur. Objective: The objective of the present study was to evaluate the effectiveness against bacterial infiltration of an intracanal barrier placed directly over the remainder of the root canal filling, after space preparation for the post. Methods: Seventy-two single-rooted human teeth were instrumented, filled and randomly divided into three experimental groups and two control groups. Group 1 received no additional treatment after filling and space preparation, while Groups 2 and 3 received a barrier composed of temporary sealing material 1.0 and 2.0 mm thick, respectively. A culture of Enterococcus faecalis was inoculated in the spaces prepared to receive the intraradicular post, every three days, for a period of 60 days. Infiltration was evaluated daily by the turbidity of the culture medium. Results and Conclusion: There was bacterial infiltration in the three experimental groups, being significantly higher and occurring more quickly in G1 (p<0.05), compared to G2 and G3. There was infiltration in all positive control groups; however, no infiltration was observed in the negative control groups. No significant difference (p>0.05) was found between G2 and G3, in relation to the rate and period of infiltration.
