【摘要】：第一部分K3、TF和K3XF鎳鈦器械對單彎透明樹脂根管成形能力的研究 目的：比較TF、K3XF和K3三種鎳鈦器械在單彎透明樹脂根管中成形能力方面的差異。方法：將45個(gè)單彎透明樹脂模擬根管隨機(jī)分為3組,分別采用TF, K3XF和K3進(jìn)行根管預(yù)備。拍攝預(yù)備前后模擬根管的數(shù)碼照片,使用圖像處理、分析軟件測量比較3組間根管彎曲度的變化和偏移情況。 結(jié)果：TF組和K3XF組的根管彎曲偏移值較小,在統(tǒng)計(jì)學(xué)上無顯著性差異(P0.05)；而K3組偏移值較大與TF組和K3XF組在統(tǒng)計(jì)學(xué)上有顯著性差異(P0.05)。 結(jié)論：在預(yù)備單彎透明樹脂根管中,新型鎳鈦器械TF和K3XF較傳統(tǒng)鎳鈦器械K3能更好地維持根管原有形態(tài)。 第二部分K3、TF和K3XF鎳鈦器械對雙彎透明樹脂根管成形能力的研究 目的：比較TF、 K3XF和K3三種鎳鈦器械在預(yù)備雙彎透明樹脂根管中成形能力方面的差異。 方法：將45個(gè)雙彎透明樹脂根管隨機(jī)分為3組,分別采用TF, K3XF和K3進(jìn)行根管預(yù)備。拍攝預(yù)備前后模擬根管的數(shù)碼照片,使用圖像處理、分析軟件測量并比較3組間根管彎曲度的變化和偏移情況,同時(shí)比較三組間預(yù)備時(shí)間和器械分離狀況。 結(jié)果：K3XF組的根管偏移值較其余兩組小,在統(tǒng)計(jì)學(xué)上有顯著性差異(P0.05)；而K3組偏移值最大與TF組和K3XF組在統(tǒng)計(jì)學(xué)上有顯著性差異(P0.05)。TF組預(yù)備完成時(shí)間(526秒)明顯小于K3XF組(684秒)和K3組(710秒)。 結(jié)論：在預(yù)備雙彎透明樹脂根管中,K3XF能夠更好地維持根管原有形態(tài),TF能夠更加快速的完成根管預(yù)備,而傳統(tǒng)鎳鈦器械K3可能造成更大的根管偏移。
[Abstract]:Part I study on the ability of K3, TF and K3XF nickel-titanium instruments to shape the root canals of single bending transparent resin objective: to compare the formability of TF,K3XF and K3 nickel-titanium instruments in single curved transparent resin root canals. Methods: 45 simulated root canals with single curved transparent resin were randomly divided into three groups. TF, K3XF and K3 were used for root canal preparation, respectively. The digital photos of simulated root canals were taken before and after preparation, and the changes and shifts of root canal curvature among the three groups were measured and compared by image processing and analysis software. Results: there was no significant difference in root canal bending offset between TF group and K3XF group (P 0.05), but there was significant difference between K3 group and TF group and K3XF group (P 0.05). Conclusion: the new nickel-titanium instruments TF and K3XF can maintain the original root canal morphology better than the traditional nickel-titanium instrument K3 in the preparation of single curved transparent resin root canals. Part II study on root canal forming ability of K3, TF and K3XF nickel-titanium instruments objective: to compare the formability of TF, K3XF and K3 nickel-titanium instruments in the preparation of double-curved transparent resin root canals. Methods: 45 double curved transparent resin root canals were randomly divided into three groups. TF, K3XF and K 3 were used for root canal preparation. The digital photos of simulated root canals were taken before and after preparation, and the changes and offsets of root canal curvature among the three groups were measured and compared by image processing, and the preparation time and instrument separation among the three groups were compared at the same time. Results: the root canal migration value of K3XF group was significantly lower than that of the other two groups (P 0.05), while the maximum deviation value of K3 group was significantly different from that of TF group and K3XF group (P 0.05). The preparation time of). TF group (526 seconds) was significantly lower than that of K3XF group (684 seconds) and K3 group (710 seconds). Conclusion: in the preparation of double curved transparent resin root canals, K3XF can better maintain the original morphology of root canals, TF can complete root canal preparation more quickly, and traditional nickel-titanium instrument K3 may cause greater root canal deviation.
