An inadequate apical seal stands out as a primary cause of disappointment in surgical endodontic procedures. Therefore, the choice of root-end filling material should aim to prevent the leakage of potential contaminants into the periapical tissue.
To evaluate and compare microleakage of chitosan nano hydrogel-incorporated mineral trioxide aggregate (MTA) and glass ionomer cement (GIC) when used as a retrograde filling material.
Sixty single-rooted premolars were decoronated at cemento enamel junction (CEJ), and root canals were prepared and obturated, with the coronal part sealed with a composite. The dye absorption was measured by an automatic spectrophotometer.
The results showed that the MTA + chitosan group had less microleakage values compared to the MTA group but was not statistically significant and GIC + chitosan had less microleakage values compared to the GIC group and was statistically significant.
Chitosan-incorporated MTA and chitosan-incorporated GIC can be considered as retrograde filling material; however, further and research and long-term clinical studies are required.
根尖封闭不充分是导致牙髓外科手术效果不佳的主要原因。因此，根尖充填材料的选择应旨在防止潜在污染物渗漏至根尖周组织。
评估并比较壳聚糖纳米水凝胶复合三氧化矿物凝聚体（MTA）和玻璃离子水门汀（GIC）作为倒充填材料时的微渗漏情况。
选取60颗单根前磨牙，在牙骨质釉质界（CEJ）处截冠，预备并充填根管，冠部用复合树脂封闭。采用自动分光光度计测量染料吸收情况。
结果显示，MTA+壳聚糖组的微渗漏值低于MTA组，但差异无统计学意义；GIC+壳聚糖组的微渗漏值低于GIC组，差异有统计学意义。
壳聚糖复合MTA和壳聚糖复合GIC可被视为倒充填材料；然而，仍需要进一步的研究和长期临床研究。
