To Assess the Adequacy of Antimicrobial Sealing gel and O-ring at the Implant-Abutment Interface to Prevent the Microleakage - An in Vitro Study

Background: Although, there are numerous treatment options, periimplantitis remains a problem in implantology that has yet to be adequately handled. Microleakage, which promotes peri-implantitis by reinfecting the implant interior areas with microbes, is one element consider. Purpose: To evaluate adequacy of antimicrobial sealing gel (Gapseal) and O-ring preventing bacterial infiltration staphylococcus aureus into internal surface implant-abutment interface. Materials Methods: One hundred twenty samples were divided three groups (n=40) based on different materials: group I (unsealed); II (Gapseal); III (O-ring).To ensure sterility, from each was incubated at random. The remaining abutment assemblies attached nutrient solution containing for next 24 hours. After incubation, decontaminated immersing them 2 percent sodium hypochlorite 30 minutes followed normal saline 5 minutes. disassembled placed test tubes sterile solution; agitated appropriately contact inner surfaces assemblies. This suspension injected onto Nutrient agar plates resultant colonies appear plate counted naked eyes. Results: Statistical analysis performed using Kruskal-Wallis variance Mann-Whitney U test. On average, number minimum (= 4.4) Group-II, 19.1) Group-III maximum 29.2) Group-I. Conclusion: application Gapseal interface reduces microbial leakage possibly increases survival rate implant-assisted restorations.
