Abstract

Background and Aim: RADIOISOTOPEs adhere to any surface in which they come in contact. Covering the sample surface with a suitable material prior to submersion and isolation of the material before counting make it possible to evaluate the penetrating RADIOISOTOPEs within the interfacial area. The aim of this study was to determine a suitable material to cover IMPLANT and abutment in evaluation of MICRO LEAKAGE in IMPLANT-abutment interface using radio tracers and gamma counter.Materials and Methods: In this in vitro study, 46 samples were selected and categorized into two groups. The first group consisted of IMPLANT samples with covered surfaces using Replace IMPLANT replica and impression coping closed tray with putty coverage, nailbrush and putty-super glue with I mm distance to the border of impression coping IMPLANT analogue interface. The second group included non-implant samples made up of putty, autopolymerizing acrylic resin, and nailbrush. This group was used for evaluation of adherence levels of the RADIOISOTOPEs. Microleakage test was performed with THALLIUM-201 and gamma counting in three phases: 1) after removing samples from thallium solution, 2) after washout of samples, and 3) after removing covering materials. In order to compare penetration of RADIOISOTOPEs within the samples analysis of co-variance was carried out.Results: There were statistically significant differences between three phases of gamma counting and between samples in different IMPLANT groups. Microleakage of IMPLANT-putty-glue was significantly less than that of IMPLANT putty (217343.40±86007.926). Similarly, IMPLANT-putty showed a significantly less microleakage than IMPLANT nailbrush. (313247.20±67933.031)Conclusion: The best material among the ones considered in this study turned to be putty sealed by super glue. Contrarily, nailbrush was not considered suitable due to increased MICRO LEAKAGE.
