目的探讨中药蟾酥失活剂与非砷类牙髓失活剂Depulpin的临床疗效。方法将212颗需进行压髓失活治疗的患牙随机分成两组,分别采用中药蟾酥失活剂和非砷类牙髓失活剂Depulpin进行处置,观察并比较两者的临床使用效果。结果非砷类牙髓失活剂Depulpin总有效率为98.25%,显效92例,有效10例,无效2例,失败0例;中药蟾酥牙髓失活剂总有效率为93.88%,显效56例,有效34例,无效2例,失败6例。两者无效及总有效率差异无统计意义,显效、有效、失败差异有统计学意义。结论中药蟾酥牙髓失活剂虽比非砷类牙髓失活剂Depulpin疗效略差,但也有一定的临床应用价值。
Objective To investigate the clinical efficacy of toad disruptor and non-arsenic dental inactivator Depulpin. Methods Totally 212 needles for medullary inactivation were randomly divided into two groups. They were treated with Chinese toad deactivator and non-arsenic type dental pulp deactivator Depulpin respectively. The clinical effects of the two methods were observed and compared. Results The total effective rate of Depulpin non-arsenic dental pulp inactivation was 98.25%, 92 cases were markedly effective, 10 cases were effective, 2 cases were ineffective and 0 cases failed. The total effective rate was 93.88% , Effective in 34 cases, invalid in 2 cases, failure in 6 cases. Both invalid and total effective rate difference was not statistically significant, effective, effective, the difference was statistically significant. Conclusion Although the effect of toad decontamination on pulp is slightly worse than that of depulpin on non-arsenic dental pulp deactivator, it is also of clinical value.
