摘要

材料和受试者用 ProTaper 通用旋转系统对 45 颗单根人类下颌前磨牙的根管进行预备,并用 Gutta Percha 和 Roeko GuttaFlow Bioseal 根管封闭剂采用侧向冷凝封闭技术进行封闭。使用 ProTaper 通用再治疗系统锉对所有样本进行再治疗,然后根据冲洗激活技术将样本分为三组。对样本进行切片,并使用连接到显微镜上的数码相机拍摄残余填充物。数据由三位不同的解释者使用 ImageJ 软件收集,以消除过程中的主观性。获得数据的平均值并进行统计评估。结果超声波激活灌洗的牙槽中剩余的填充材料(冠水平为 6.17 ± 1.42,中水平为 10.93 ± 1.91,根尖水平为 14.58 ± 2.23)少于激光激活灌洗的牙槽中(冠水平为 15.87 ± 3.78,中水平为 21.28 ± 4.44,根尖水平为 27.06 ± 2.68)。使用被动式侧排气注射器灌洗的根管中残留的充填材料最多(冠水平为 23.07 ± 3.22,中水平为 38.09 ± 7.27,根尖水平为 34.24 ± 9.77)。

Impact of LASER activated irrigation on the retrievability of Guttaflow bioseal (in-vitro study)

Background

This study aimed to evaluate the efficiency of diode LASER activated irrigation in the removal of GuttaFlow Bioseal root canal filling material during retreatment.

Materials and subjects

Root canals of forty-five single-rooted human mandibular premolar teeth were prepared with ProTaper Universal rotary system and obturated with lateral condensation obturation technique using Gutta Percha and Roeko GuttaFlow Bioseal root canal sealer. All specimens were retreated with ProTaper Universal Retreatment System files then divided to three different groups according to the technique of activation of irrigation. Samples were sectioned, and the residual filling remnants were captured using digital camera attached to microscope. Data was collected by three different interpreters, to eliminate the subjectivity of the process, using the ImageJ Software. The mean value of the data was obtained and evaluated statistically. The significance level was set at P ≤ 0.05.

Results

The remaining filling materials in the canals irrigated with ultrasonic activation (6.17 ± 1.42 at coronal level, 10.93 ± 1.91at middle level, and 14.58 ± 2.23 at apical level) were less than these irrigated with LASER activation (15.87 ± 3.78 at coronal level, 21.28 ± 4.44 at middle level, and 27.06 ± 2.68 at apical level). Maximum amount of remaining filling materials was present in the canals irrigated with passive side-vented syringe (23.07 ± 3.22 at coronal level, 38.09 ± 7.27 at middle level, and 34.24 ± 9.77 at apical level).

Conclusion

The activation of irrigation techniques used were incapable of complete removal of filling material at root canal walls.
