TY - JOUR TI - Does The Vehicle Type Affect the Persistence of CalciumHydroxide When Removing with Sonic Activation? AB - Background: This in vitro study aimed to evaluate thepersistence of calcium hydroxide (CH) associated with differentvehicles on the artificial cavities after removing with sonicactivation or conventional needle irrigation (CNI). Methods: Seventy-two extracted single-rooted teeth wereinstrumented with ProTaper Universal rotary system up to F4.The roots were split longitudinally, and standardized cavitieswere prepared. The roots were assigned into 3 groups (n=24),according to vehicles used; distilled water, glycerin, andpropylene glycol. In each group, cavities were filled with CHmixed with the respective vehicle. After reassembly, the removalof CH dressing was performed with either sonic activation(EDDY) or CNI (n=12). The remnants of CH were assessedunder a microscope at ×40 magnification. A four-grade scoringsystem was used to evaluate. Kruskal-Wallis and Mann-WhitneyU-tests were used to compare the data. Results: There was a significant difference among groups(p=0.000). Complete removal of CH was found in the distilledwater and propylene glycol groups when EDDY was used. EDDYwas significantly more effective than CNI in the removal of CHmixed with distilled water and propylene glycol p=0.001 andp=0,002, respectively. Whereas no significant difference wasfound between EDDY and CNI in the glycerin group (p=0.219).The lowest CH remnants were found in the distilled water groupwhen CNI was used. Conclusion: The vehicle associated with CH and irrigationactivation is important for its retrieval. EDDY provided thecomplete removal of CH when mixed with distilled water orpropylene glycol.
