【摘要】：目的:利用樹脂模擬根管比較ProTaper Universal、ProTaper Next與M3預(yù)備模擬根管的成形效果。方法:選取透明樹脂模擬根管30個,隨機(jī)分為3組,PU組、PN組和M3組,每組各10個。分別用ProTaper Universal、ProTaper Next和M3進(jìn)行根管預(yù)備,記錄根管預(yù)備時間、預(yù)備前后的形態(tài)圖像。使用圖像處理、分析軟件測量各觀測點樹脂切割量,計算根管偏移程度以及根尖孔碎屑溢出量。結(jié)果:ProTaper Next、M3較ProTaper Universal根管預(yù)備時間短,在多個測量點的根管偏移程度小于ProTaper Universal,差異顯著,有統(tǒng)計學(xué)意義(P0.05),ProTaper Next根尖孔碎屑溢出量少于ProTaper Universal、M3。結(jié)論:ProTaper Next和M3預(yù)備彎曲根管時能較好地保持原有根管形態(tài),省時省力,值得推廣。
[Abstract]:Aim: to compare the effects of ProTaper Universal ProTaper next and M 3 on the formation of simulated root canals. Methods: thirty transparent resin simulated root canals were randomly divided into 3 groups, PN group and M3 group, 10 in each group. ProTaper Universal ProTaper next and M3 were used for root canal preparation respectively. The root canal preparation time was recorded and the morphological images before and after preparation were recorded. Using image processing, the analysis software was used to measure the resin cutting quantity of each observation point, to calculate the root canal deviation degree and the root tip hole debris overflow amount. Results compared with ProTaper Universal root canal preparation time was shorter than that of ProTaper Universal root canal preparation time. The root canal deviation at multiple measurement points was smaller than that of ProTaper Universal, and the difference was significant. There was a statistically significant difference in the amount of debris spill in ProTaper next apical foramen than that in ProTaper Universal Universal Root Canal. Conclusion when preparing curved root canals, the ratio ProTaper next and M3 can better maintain the original root canal morphology, save time and effort, and be worth popularizing.
