Sažetak
Aim: To evaluate bacterial coronal microleakage of MTA andamalgam as root-end fillings of roots orthogradly filled with gutta-percha and three root canal sealers. Methodology: A total of 108 single rooted teeth were randomly divided into three groups of 32 teeth each and positive and negative control groups of six teeth. Following root canal preparation thecanals were filled using cold lateral compaction of gutta-percha and either Diaket, AH Plus or Ketac Endo. Each of the three groups was further divided into two subgroups of 16 teeth and the apical rootends were re-sected, cavities prepared and filled with either MTA orzinc free amalgam. The samples were incorporated in a model system so that the apical part of the sample was dipped intouncontaminated buyon, while 0.5 mL of the buyone contaminated with a polymicrobial marker of five facultative anaerobes (Streptococcus Mutans 6715 WT, Streptotoccus Mitis, LactobacillusSpecies NCTC1723, Staphylococcus Aureus ATCC 29213, Enterococ-cus Faecalis ATCC 29212) was placed on the coronal part of each sample. The teeth were checked for bacterial leakage daily for90 days and the exact day of buyon contamination was recorded for every sample. The obtained data were analyzed using descriptive statistics, variance analysis, Sheffe post hoc test and Kaplan Meiertest. Results: The longest period before leakage was observed with combination of Diaket sealer and MTA root-end filling (76.9 ±14.8 days) followed by AH Plus and MTA (66.1 ± 18.7), Diaket and amalgam (60.0 ± 23.1), AH Plus and amalgam (56.9 ± 22.1), Ketac Endo and MTA (42.1 ± 17.8) while the shortest period before leakage was observed in the Ketac Endo and amalgam group(40.0 ± 17.24). Groups sealed with Diaket and AH Plus leaked after a significantly longer time (P < 0.05) than groups with Ketac Endo. Groups filled with MTA leaked after a significantly longer time (P < 0.05) than amalgam. Conclusions: MTA in combination with Diaket were associated with the longest period of time prior to leakage
