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.
尽管在牙髓治疗中使用了许多材料进行根管填充，但由于氢氧化钙具有杀菌作用和生物相容性，多年来一直受到青睐。氢氧化钙可以以多种形式应用。在本病例研究中，在牙髓治疗过程中，将粘性形式的氢氧化钙应用于根管中，从牙齿的根尖部溢出到下颌牙槽神经管。术后观察到患者出现感觉异常。进行了牙科容积断层扫描，以研究在下颌牙槽神经管中的密封剂的范围。考虑到氢氧化钙糊剂的短吸收时间，未对患者进行手术干预。6 个月后，根管材料完全吸收，感觉异常减轻。在 3 年的随访中，患者的感觉异常完全消失。
