説明
<p>Abstract : The aim of this study was to evaluate the efficiency of laser-activated irrigation (LAI) in cleaning accessory root canals. Simulated root canal models with accessory canals were used. Accessory canals of 0.5 mm diameter were located at 1, 3, 5, 10 mm from the apex. Accessory canals were filled with the flowable radiolucent material, CalcipexⅡ®. Root canals were irrigated with Er:YAG laser-activated irrigation (LAI) or syringe irrigation. Three groups (n=4) were evaluated as follows : Group 1 : LAI with a cone-shaped tip for 20 s at 30 mJ and 20 pps, stationary method ; Group 2 : LAI with a cone-shaped tip at 30 mJ and 20 pps, pull-up method (1 mm/s) ; Group 3 : syringe irrigation with 3 mL water. Digital X-ray photographs using microtomography were analyzed for the quantity of radiolucent material remaining after irrigation. Overall comparison (average of the material-removed area from all four accessory canals) between irrigation methods was performed using the Tukey-Kramer test. Differences between the four accessory canals after each irrigation method were also investigated. Statistically significant differences (p<0.01) were found between the LAI and syringe irrigation groups. LAI was more effective in cleaning the accessory root canals than syringe irrigation. The effect of LAI in the upper accessory canal was lower than that in the other accessory canals. Especially, the stationary method showed this tendency more remarkably than the pull-up method. These results suggest that LAI irrigation using Er:YAG laser equipped with a cone-shaped tip may be promising in cleaning accessory root canals.</p>
