Abstract：
UNASSIGNED: Tooth fracture is one of the most common traumatic maxillofacial injuries in dogs and cats. For fractures with pulp exposure occurring in functionally important teeth, the literature indicates that root canal treatment (RCT) is an effective therapy option that may be the remedy of choice before extraction. The most commonly reported fractures in the United States involve canine teeth; however, fractures of the maxillary fourth premolars are more common in Korea, where there are many small-and medium-sized dogs. RCT mechanically and chemically removes pulp tissue and bacteria (cleaning and shaping) from the infected root canal, and obturates the root canal with filling material to restore tooth functionality without inflammation. Various techniques, instruments, and materials used in humans have been modified for application in veterinary dentistry.
UNASSIGNED: This study analyzed the results of RCT of the maxillary fourth premolar in 120 small-and medium-sized dogs (weighing less than 25 kg) using three different sealers (silicone-based sealer, bioceramic sealer, and calcium hydroxide-based sealer) through a simple application of the single-cone technique.
UNASSIGNED: The overall success rate of RCT in maxillary fourth premolars was 90.83%, with 8.33% no evidence of failure (NEF) and 0.83% failure.
UNASSIGNED: There were no significant differences between the three different sealers. Furthermore, preexisting periapical lesion (PAL) was reconfirmed as a factor in reducing the success rate of RCT. In addition, the working length and master apical file of each root were analyzed in our study as a novel reference for endodontic veterinarians.

摘要：
■牙齿骨折是狗和猫最常见的创伤性颌面部损伤之一。对于功能重要的牙齿中发生的牙髓暴露骨折，文献表明，根管治疗（RCT）是一种有效的治疗选择，可能是拔牙前的选择。在美国，最常见的骨折涉及犬齿；然而，上颌第四前磨牙骨折在韩国更为常见，那里有许多中小型的狗。RCT以机械和化学方式从感染的根管中去除牙髓组织和细菌（清洁和整形），并用填充材料封闭根管，以恢复牙齿功能而没有炎症。各种技术,仪器,和用于人类的材料已经被修改用于兽医牙科。
■这项研究分析了使用三种不同的密封剂（基于硅胶的密封剂，生物陶瓷封口机，和氢氧化钙基密封剂）通过简单的单锥技术应用。
■上颌第四前磨牙RCT的总体成功率为90.83%，8.33%无故障证据(NEF)和0.83%故障。
■三种不同的密封剂之间没有显着差异。此外，先前存在的根尖周病变（PAL）被再次确认为降低RCT成功率的因素。此外,在我们的研究中分析了每个根的工作长度和主根尖文件，作为牙髓兽医的新参考。
