Efficacy of XP-endo Finisher, XP-endo Finisher R, CanalBrush and EndoActivator in the removal of Intracanal Medicament (An in Vitro Study)

Teeba Talal Abdul Aziz, Iman M. Al Zaka

Abstract: The aim of this study was to evaluate and compare the efficacy of XP-endo Finisher, XP-endo Finisher R, CanalBrush and EndoActivator in the removal of Intracanal medicament. Sixty freshly extracted upper molar teeth with straight palatal roots were used in this study; all roots were shortened to a length of 12 mm. Canals were prepared with RECIPROC blue file R40 and irrigated with 10 ml of 2.5 % NaOCl. Then the roots were split longitudinally. Two of the three standard grooves were created in the coronal and apical parts of one of root halves, and the other in the middle part of the second halves then each of the root halves and grooves was irrigated with 5 ml 17 % EDTA for 60 sec. and 5 ml 2.5 % NaOCl for 60 sec. The standardized grooves were filled with Ca (OH) 2 and the root halves were reassembled. After 7 days, R40 file at WL was used to get a space for irrigation needle and instruments. After that specimens were randomly divided into 4 experimental groups (n=15/group). Ca (OH) 2 was removed with different instruments as follow: Group (): CanalBrush, Group (): EndoActivator, Group (III): XP-endo Finisher, and Group (IV): XP-endo Finisher R. 5 ml 2.5 % NaOCl irrigation was used before and after every cleaning procedure with each instrument. The amount of remaining Ca (OH) 2 in the grooves was scored under a Stereomicroscope at 30X magnification. Statistical evaluation was performed using KruskalWallis and Wilcoxon Sum rank test. The results showed that cleaning with XP-endo Finisher R (IV) resulted in significantly cleaner canals (P 0.05) than CanalBrush (), EndoActivator (), and XP-endo Finisher (III) at all canal levels. XP-endo Finisher resulted in cleaner canals than CanalBrush, EndoActivator at all levels, but with insignificant statistical difference (P>0.05). Apical level of all canals showed greater amount of Ca (OH) 2 remnants in compared to middle and coronal levels, whatever instruments were used. Apical groove was significantly difference from coronal groove (P0.05) in all groups. None of the investigated instruments were able to completely removed all Ca (OH) 2 from the three root regions
