Teeth with induced chronic periradicular periodontitis in dogs were root canal treated. After the biomechanical preparation, using K files and 5.25% sodium hypochlorite as the irrigant solution, all root canals were dressed with an antibacterial dressing based on calcium hydroxide, which was left in place for 7 days. After this time, the root canals were obturated with lateral condensation of cold gutta-percha with either a calcium hydroxide root canal filling material (Sealapex) or a zinc oxide-eugenol sealer (Fill Canal). After 270 days, histopathological analysis showed better apical and periapical repair in the teeth obturated with Sealapex (P < 0.05).
对患有诱导性慢性根尖周炎的犬牙进行根管治疗。在使用K锉和5.25%次氯酸钠作为冲洗液进行生物力学预备后，所有根管均用基于氢氧化钙的抗菌敷料进行封药，该敷料留置7天。此后，用冷牙胶侧方加压充填根管，充填材料为氢氧化钙根管充填材料（Sealapex）或氧化锌丁香酚封闭剂（Fill Canal）。270天后，组织病理学分析显示，用Sealapex充填的牙齿根尖和根尖周修复情况更好（P<0.05）。
