CRCS, N2 universal, sealapex ve endomethasone kanal dolgu maddelerindeki apikal sızıntının iki farklı yöntemle araştırılması

Abstract

m SUMMARY In this in vitro study, apical sealing capabilities of four different root canal fillings (CRCS, N2 Universal, Sealapex, Endomethasone) were compared by linear dye penetration and electro chemical II methods. 192 maxillary incisor and canine teeth were divided equally into four groups. Linear dye penetration method was applied to the three groups, and the electro-chemical method to only one. In linear dye penetration method, 2 per cent methylene blue dye was used; and the teeth in the first, second, and third groups were immersed in it for 24 hours, 3 months, and 6 months, respectively. The apical leakaye of each tooth in the forth group were measured per day for a 32-day period by electro chemical method. The leakage amounts measured by both methods were analysed by variance analysis and Duncan's multiple range test. It has been observed by linear dye method that no statiscally significant difference was found among all the filling materials at the 24-hour and 3-month periods. At the sixth month N2 Universal showed the least leakage (p<0,01). The other three filling materials did not show any significant differences regarding leakage at the same period. It has also been determined that the Leakage amounts of all filling materials at the last period were more than those at the previous periods (p<0,01). In electro chemical method, the leakage amount caused by Endomethasone was significantly higher than those of the others (p<0,001). The leakage differences among CRCS, N2 Universal, and Sealapex were not statistically significant (p>0,05).
