To Evaluate and Compare the Antibacterial Efficacy of Two Sealing Agents at the Implant - Abutment Interface - An In-Vitro Study

Dr. Bhavyashree R | Dr. Jnanadev K R


Abstract: Background: Colonization of bacteria along the implant-abutment interface micro gap may establish a bacterial reservoir, which can result in soft tissue inflammation, thereby increasing the risk of peri-implantitis and marginal bone loss. Micro gaps along the implant-abutment interface can enlarge under loading conditions and create a? pump like effect? around the bone leading to large amounts of bacteria into the implant. Sealing agents have been reported to reduce the bacterial colonization by filling the micro gaps. Objective: The objective of the study is to compare the antibacterial efficacy of two sealing agents at the implant-abutment interface. Materials and method: A total of 10 implants and abutments were selected for the study and divided into two groups. Sealing agents were applied at the IAI of implant groups. Abutments were connected to the implants, and bacteria were inoculated. Bacterial percolation was evaluated by culturing the specimen from the internal aspect of implants on agar plates after incubation. Efficacy was evaluated by counting the colonies (colony forming units) on the agar plates. Results: Mean of colony forming units for CHX gel was calculated to be 239.80 ? 72.30 cfu, for Loctite 243 was 92 ? 124.09 cfu. In the present study, least value of colony?forming units of bacteria was exhibited by IAIs sealed with Loctite 243. Conclusion: Application of CHX varnish and antibacterial sealing gel can reduce the bacterial leakage through IAI. The application of Loctite 243 provides better sealing than CHX gel. The difference was also statistically significant.
