The aim of this study was to evaluate periapical repair after root canal filling with different endodontic sealers. Sixty-four root canals from dog s teeth were filled, divided into 4 groups (n=16). Root canals were instrumented with K-type files and irrigated with 1% sodium hypochlorite solution. Root canals were filled in the same session by active lateral condensation of the cones and sealers: Intrafill, AH Plus, Roeko Seal and Resilon/Epiphany System. After 90 days, the animals were euthanized and the tissues to be evaluated were processed and stained with hematoxylin and eosin. For histopathological analysis, the following parameters were evaluated: inflammatory process, mineralized tissue resorption, and apical mineralized tissue deposition. Histopathological analysis demonstrated that Intrafill had less favorable results in terms of apical and periapical repair, compared to the other sealers (p<0.05). AH Plus, Roeko Seal, and Epiphany sealers had similar and satisfactory results (p>0.05). In conclusion, AH Plus and the materials Roeko Seal and Epiphany are good options for clinical use in Endodontics.
本研究的目的是评估使用不同根管封闭剂进行根管充填后的根尖周修复情况。对犬牙的64个根管进行充填，分为4组（每组n = 16）。用K型锉对根管进行预备，并用1%次氯酸钠溶液冲洗。在同一次就诊时，通过牙胶尖和封闭剂的主动侧向加压对根管进行充填：Intrafill、AH Plus、Roeko Seal和Resilon/Epiphany系统。90天后，对动物实施安乐死，并对待评估组织进行处理，用苏木精和伊红染色。进行组织病理学分析时，评估以下参数：炎症过程、矿化组织吸收以及根尖矿化组织沉积。组织病理学分析表明，与其他封闭剂相比，Intrafill在根尖和根尖周修复方面的结果较差（p<0.05）。AH Plus、Roeko Seal和Epiphany封闭剂的结果相似且令人满意（p>0.05）。总之，AH Plus以及Roeko Seal和Epiphany材料是牙髓病学临床应用的良好选择。
