Abstract：
Although many materials are used for root canal fillings in endodontic treatment, calcium hydroxide has been preferred for many years due to its bactericidal effect and biocompatibility. Calcium hydroxide can be applied in more than one form. In this case study, calcium hydroxide in viscous form, applied into the root canal during endodontic treatment, overflowed from the apical part of the tooth to the inferior alveolar nerve canal. Postoperative paraesthesia was observed in the patient. Dental volumetric tomography was performed to study the extent of sealer in the inferior alveolar nerve canal. Considering the short resorption time of the calcium hydroxide paste, no surgical intervention was performed on the patient. After 6 months, the root canal material was completely resorbed, and paraesthesia decreased. At the 3-year follow-up, the patient\'s paraesthesia had completely disappeared.
摘要：
尽管在牙髓治疗中许多材料用于根管充填，氢氧化钙由于其杀菌效果和生物相容性多年来一直是首选。氢氧化钙可以以一种以上的形式应用。在这个案例研究中,粘稠形式的氢氧化钙，在牙髓治疗期间应用于根管，从牙齿的顶端溢出到下牙槽神经管。术后观察到患者的感觉异常。进行了牙科容积断层扫描，以研究下牙槽神经管中密封剂的范围。考虑到氢氧化钙糊的吸收时间短，未对患者进行手术干预.六个月后,根管材料完全再吸收，感觉异常减少。在3年的随访中，病人的感觉异常完全消失了。
