The purpose of this investigation was to assess the effectiveness of various gutta-percha retrieval methods in endodontic retreatment.
Five groups were randomly allocated to extract human teeth that had already had root canal therapy: manual files, rotary tools, heat, solvents, and ultrasonics. By evaluating the amount of filling material still present, gutta-percha clearance was quantitatively examined, and root canal cleanliness was qualitatively appraised. To compare the effectiveness of retrieval approaches, statistical analysis was done.
Hand files, heat, and solvents were less effective than rotary devices and ultrasonics at removing gutta-percha ( < 0.05). A quantitative investigation showed that the groups using rotary instruments (0.87 mm) and ultrasonics (0.68 mm) had much less gutta-percha left. The qualitative evaluation revealed that rotary instruments (2.12) and ultrasonics (2.45) had greater cleaning ratings compared to other methods.
In conclusion, gutta-percha can be effectively removed during endodontic retreatment by using rotary tools and ultrasonics, which provide both quantitative efficiency and qualitative purity. The implementation of sophisticated retrieval procedures to maximize treatment results in clinical practice is supported by these findings.
本研究的目的是评估各种根管充填材料取出方法在根管再治疗中的有效性。
将五组随机分配用于拔除已进行根管治疗的人牙，分别采用手动锉、旋转器械、加热、溶剂和超声等方法。通过评估仍存在的充填材料量，对根管充填材料的清除情况进行定量检查，并对根管清洁度进行定性评估。为比较取出方法的有效性，进行了统计分析。
在去除根管充填材料方面，手动锉、加热和溶剂的效果不如旋转器械和超声（P<0.05）。定量研究表明，使用旋转器械（0.87mm）和超声（0.68mm）的组残留的根管充填材料要少得多。定性评估显示，与其他方法相比，旋转器械（2.12）和超声（2.45）的清洁评分更高。
总之，在根管再治疗过程中，使用旋转器械和超声可以有效地去除根管充填材料，它们兼具定量效率和定性纯度。这些研究结果支持在临床实践中采用复杂的取出程序以最大限度地提高治疗效果。
