Introduction: The aim of this paper is to investigate the radiopacity of calcium hydroxide-based medications via means of contemporary image analyzing methods.
Methods: Three commercial calcium hydroxide-based medications were used. Radiographic image data was obtained according to the International Organization for Standardization #6876(2012) specifications. Region of interest was determined for each specimen. Mean (±SD) grey values of the X-ray image data was measured with an image analyzing software. The calibration curve was created by curve-plotting software and the mean grey-values were matched versus Al values (mm Al). Data were analyzed with one-way ANOVA followed by Tukey’s multiple comparison test.
Results: The radiopacity values of all medications are significantly different (p<0.05). The rank of the radiopacity values: TempCanal (4.94±0.31mmAl) > ProCalR (2.63±0.05mmAl) > Control (2.19±0.11mmAl).
Discussion and Conclusion: There was a high difference in the radiopacity values of the radiopaque calcium hydroxide-based medicaments. Although the medicaments showed radiopacity of 2.19 to 4.94 mm aluminum equivalent, only TempCanal had values above the international standards as 3 mm aluminum equivalent.
