目的回顾4例因使用慢性失活剂Depulpin致牙髓快速坏死病例诊治经过,对其特殊情况进行分析,为临床治疗提供参考。方法对2008-02-2010-02在门诊诊治的4例牙髓炎患者给予慢性失活剂Depulpin封药失活牙髓。结果本应需10~15 d才达到牙髓失活目的该4例病例,最快24 h、最迟48 h内均出现局部剧烈疼痛且牙髓完全坏死的例外情况。结论使用慢性失活剂Depulpin封药使牙髓失活时,若短期内出现局部剧烈疼痛等异常情况时,需考虑牙髓已快速坏死的特殊情况,并作相应处理,而不能仅当作封药后的常见炎性反应。
Objective To investigate the diagnosis and treatment of 4 cases of rapid necrosis of pulp caused by chronic inactivation of Depulpin, and to provide a reference for clinical treatment. Methods Four patients with pulpitis diagnosed in the clinic from February 2008 to February 2010 were given chronic inactivation agent Depulpin sealant to inactivate dental pulp. The results should be 10 ~ 15 d to achieve the purpose of inactivation of the pulp. The 4 cases, the fastest 24 h, the latest within 48 h were severe local pain and pulp necrosis exception. Conclusions In the event of deactivation of the dental pulp using the chronic inactivating agent Depulpin seal, special cases of rapid necrosis of the dental pulp should be considered if abnormalities such as severe local pain occur in a short period of time, and should be dealt with accordingly, not only as a seal Common inflammatory reaction after drug.
