摘要： 目的:体外比较单支锉ProTaper Sx和不锈钢K锉预备乳牙根管的时间和根尖推出物量。方法:门诊收集离体乳牙,经截冠、分根后,按远中根管、近中根管、前牙根管、腭根管、近颊根管及远颊根管六种根管类型各收集16个,共96个。将每种类型根管随机均匀分配至Sx组(n=48)和K锉组(n=48)。分别用ProTaper Sx和不锈钢K锉进行根管预备,各根管均用10 mL 0.2%氯己定溶液冲洗,记录预备时间、测定根尖推出碎屑量和根尖渗出冲洗液量,进行统计学分析。结果:K锉组(328.8s)的预备时间是Sx组(180.9 s)的近1.8倍,差异有统计学意义(P<0.05)。两种器械均会造成一定的根尖推出物,但推出物的量不同。Sx组的根尖推出碎屑量和根尖渗出冲洗液量(0.00128±0.00056) g;(0.00614±0.00183) g均低于K锉组(0.00345±0.00124) g;(0.02930±0.01879) g,差异均有统计学意义(P<0.05)。结论:与不锈钢K锉相比,单支锉ProTaper Sx预备乳牙根管具有预备时间短、根尖推出物量少的特点。

Abstract: Objective: To compare the amount of apical extrusions of rotary instrument ProTaper Sx and stainless steel K-file for root canal preparation of primary teeth in vitro. Methods: Isolated deciduous teeth were collected from the outpatient department. After coronal cutting and root separation, the distal root canal, proximal root canal, anterior root canal, palatal root canal, proximal buccal root canal, and distal buccal root canal were classified into 16 root canals of each type, a total of 96. The root canal types were divided into two groups: Sx group (n=48) and K-file group (n=48) randomly. ProTaper Sx and K-files combined with 10mL 0.2% chlorhexidine solution were used for root canal preparation. The preparation time was recorded, and the amount of apical debris and exudation was measured. Results: The preparation time of K-file group (328.8s) was longer than that of Sx group (180.9s, P<0.05). Both of two instruments could cause a different amount of apical debris and exudation. In Sx group, the amount of apical debris and exudation (0.00128±0.00056) g; (0.00614±0.00183) g was lower than that of K-file group (0.00345±0.00124) g; (0.02930±0.01879) g, P<0.05. Conclusion: Compared with stainless steel K-file, ProTaper Sx could shorten preparation time and reduce the amount of apical extrusions in primary teeth
