Abstract

Introduction: The absence of a barrier in an open root apex makes endodontic treatment challenging as root-filling material can easily reach the surrounding tissue. The aim of the study was to compare the apical microleakage associated with mineral trioxide aggregate (MTA), biodentine, custom-made gutta-percha with MTA plus and custom-made gutta-percha with Adseal in immature permanent teeth by dye penetration method. Methods: Apical 2 mm of 60 single-rooted mandibular premolar teeth was resected to create divergent open apices and 10 teeth each were filled with Biodentine plug, MTA plug, custom-made gutta-percha with MTA plus sealer and custom-made gutta-percha with Adseal sealer. Ten teeth each acted as positive and negative controls. All the samples were stored at 37°C at 100% humidity for 5 weeks and then immersed in 2% Rhodamine B dye for 24 h. Transverse sectioning was done apically at 1 mm and 3 mm to evaluate dye penetration under a fluorescence microscope using ImageJ software. Results: There was a significantly greater microleakage at 1 mm cross section compared to 3 mm (p < 0.0001). At 1 mm cross section, the apical microleakage was the highest for the MTA plug with a mean leakage percentage of 48.08 ± 16.38, a mean depth of leakage of 0.46 ± 0.10 mm and a mean area of leakage of 1.35 ± 0.74 mm2, compared to other groups, and the difference was statistically significant. However, at a 3 mm cross section, MTA plus sealer with gutta-percha demonstrated the highest mean leakage percentage (25.01 ± 7.77) compared to other groups and the difference was statistically significant (p = 0.03). Conclusion: It can be concluded that the 3-mm-thick apical plug provided better sealing of the open apex compared to the 1 mm apical plug and there was no significant difference in microleakage among the Biodentine plug, MTA plug and Adseal sealer with gutta-percha plug at 3 mm cross section.

评估未成熟恒牙正交根充材料的微渗漏:体外研究
导言:开放的根尖没有屏障,使得根管治疗具有挑战性,因为根充材料很容易到达周围组织。本研究的目的是通过染料渗透法,比较未成熟恒牙中与三氧化二铝矿物质骨料(MTA)、生物碱、定制的古塔波瓷加 MTA 和定制的古塔波瓷加 Adseal 相关的根尖微渗漏情况。方法:切除 60 颗单根下颌前磨牙的根尖 2 毫米,形成分叉开放的根尖,并分别用 Biodentine 栓塞、MTA 栓塞、定制的带有 MTA plus 封闭剂的古塔波查和定制的带有 Adseal 封闭剂的古塔波查填充各 10 颗牙齿。阳性和阴性对照组各 10 颗牙齿。使用 ImageJ 软件在荧光显微镜下评估染料的渗透情况。结果:与 3 毫米横切面相比,1 毫米横切面的微渗漏率明显更高(p < 0.0001)。与其他组相比,在 1 毫米横截面上,MTA 插塞的顶端微渗漏最高,平均渗漏百分比为 48.08 ± 16.38,平均渗漏深度为 0.46 ± 0.10 毫米,平均渗漏面积为 1.35 ± 0.74 平方毫米,差异具有统计学意义。然而,在 3 毫米的横截面上,与其他组别相比,MTA 加带古塔漆的封闭剂的平均渗漏百分比(25.01 ± 7.77)最高,差异有统计学意义(p = 0.03)。结论可以得出结论,与 1 毫米的根尖塞相比,3 毫米厚的根尖塞能更好地密封开放的根尖,而且在 3 毫米横截面上,Biodentine 塞、MTA 塞和 Adseal 密封剂加古塔碱塞在微渗漏方面没有显著差异。
