- Abstract
Bacterial infiltration may affect the bone/implant and implant/abutment interface and contribute to the hatilose and periimplantitis, leading to patient dissatisfaction and may interfere with the longevity of the implants. This in vitro study aimed to evaluate the effectiveness of sealing material (Kiero Seal) against bacterial infiltration on the implant/abutment interface. For this, forty implants with cone morse connections were used. The samples were divided into two groups (n = 20): Group 1. Implants linked with abutment were sealed with Kiero Seal material. Group 2. The implants and abutments had no sealing material. For microbiological tests, it was carried out the inoculation of 1 uL of Escherichia coli suspension diluted in sterile saline into the inner empty portion of the implant. After inoculation, the abutments were sealed with Kiero Seal varnish material during 5 minutes. Then, the abutments were connected immediately to the respective implants and screwed with 20 N.cm. After, the sets implant/abutment were completely immersed in sterile test tubes containing culture environment with Escherichia coli at 37 °C, and the analysis were performed after 24 h, 48 h, 5 days, 7 days and 14 days. Two implants were used as negative control, without bacteria, with one being sealed and one unsealed. The culture medium contamination was direct observation by the turbidity of the environment, classifying the positive or negative. The data were analysed by Q Cochran and Binomial tests, and the significance level was 5%. It was observed that the incubation time did not significantly affect the turbidity of the culture environment with sealed implant/abutment interface (p = 0.406). By the other hand, when the set implant/abutment was not subjected to the sealing, significant increase in the number of turbid environment with the elapse of time was noted (p = 0.003). It can be concluded that the sealing with Kiero Seal material was effective against bacterial infiltration on implant/abutment interface.
