EVALUATION OF SURFACE TENSION OF A NEWLY DEVELOPED IRRIGATION SOLUTION AND DIFFERENT IRRIGANTS

The aim of the present study was to compare the surface tension values of a newly developed irrigation solution sbt and different irrigation solutions (%5,25 naocl, %2 chx, mtad, ozonated water) at room temperature. the newly developed irrigation solution sbt includes streptokinase, barium sulphate and tween 80. the determination of the surface tension of the irrigants was done by the drop method with traube stalogmometer. the surface tension of solutions was calculated with an equation based on hagen-poiseuille law. it was observed that naocl (84,93 mj/m2) had the highest surface tension and mtad had the least surface tension, while the surface tension of sbt was found as 48,55 mj/m2. additionally, the surface tension of ozonated water and chx was determined as 72,80 mj/m2, 60,66 mj/m2 respectively. with the limitations of this study, it can be concluded that low surface tension of sbt may ensure high penetration of irrigation solution to the root canal dentin.
