A comparison of the surface tension of calcium hydroxide mixed with different vehicles

The aim of this study was to evaluate and compare the surface tension of di fferent liquids that are used as potential agents to mix with calcium hydro xide in root canal treatment. We also tried to evaluate final surface tensi on values of the calcium hydroxide mixed with glycerin, Ringer's solution, anesthetic solution, and saline. Surface tension values were measured using a "Du Nouy" tensiometer, The results showed statistically significant diff erences between vehicles alone and the calcium hydroxide combinations and a lso indicated that anesthetic solution (p = 0.018, p less than or equal to 0.02) is the most favorable vehicle with the lowest surface tension values.
