| الوصف: | Aim: To evaluate the efficacy of sonic irrigation (EndoActivator®) using various polymer tips and power-settings in a stained collagen ex-vivo model. / Methodology: Fifty human, straight single-rooted extracted teeth were prepared to size 40,.08 taper. The roots were split longitudinally; stained collagen applied to the canal surfaces, photographed and re-assembled. The canals were subjected to syringe without supplementary (Group 1, n = 10), or with supplementary sonic (groups 2–5, n = 10) irrigation. EndoActivator® tip sizes (size 15, .02 taper for groups 2 & 3, size 35,.04 taper for groups 4 & 5) and power-settings (Low for groups 2 & 4, high for groups 3 & 5) were tested. After irrigation, the canals were re-photographed and the area of residual stained-collagen was quantified using the UTHSCA Image Tool program (Version 3.0). The data were analysed using Wilcoxon signed rank test and General Linear Mixed Models. / Results: Supplementary sonic irrigation using EndoActivator® resulted in significantly (P < 0.0001) less residual collagen compared with syringe irrigation only. Agitation of irrigant using the large EndoActivator® tip with high-power resulted in significantly less (22.4% – 29.5%) residual collagen compared to other combinations (large-tip/low-power P = 0.001; small-tip/low-power P = 0.01; small-tip/high-power P = 0.04). There was no significant difference amongst the latter three groups (P > 0.5). / Conclusions: Supplementary sonic irrigation using the EndoActivator® system was significantly more effective in removing stained collagen from the canal surface than syringe irrigation alone. EndoActivator® used with large-tip (size 35, .04 taper) and high power-setting in size 40,.08 taper canals was more effective than other combinations. |
