干髓疗法在一百多年前已被较广泛应用,在当前也是临床上一种常用的牙髓病的疗法。作者根据Holden等认为冷冻可使感觉神经末梢破坏而失去感觉等作用,以及Emming等在狗的下颌骨进行冷冻试验发现:在冷冻区域的牙齿失去活力等现象。为了缩短疗程与提高干髓疗法的疗效,乃于1978年10月开始应用液氮冷冻一次完成干髓疗法,共治疗32例,经随访观察,效果尚满意,现将资料小结如下。适应证: 一、慢性溃疡性或增生性牙髓炎,无明显根尖病变的后牙。二、意外露髓不适宜于保存活髓的后牙。三、干髓疗法失败者(对冷热刺激痛)。
Dry pulp therapy has been more than 100 years ago has been more widely used, is currently a clinically common endodontic therapy. According to Holden et al., Freezing may cause sensory nerve endings to be destroyed and lose sensation, and Emming et al. Performed a freeze test on the mandible of a dog and found that the teeth in the frozen area lost their vitality. In order to shorten the course of treatment and improve the efficacy of dry pulp therapy, but in October 1978 began a single application of liquid nitrogen frozen dry marrow therapy, a total of 32 cases were treated, follow-up observation, the effect is still satisfactory, the data summarized below. Indications: First, chronic ulcerative or proliferative pulpitis, no obvious apical lesions of the posterior teeth. Second, the accidental exposed pulp is not suitable for preservation of vital pulp of the posterior teeth. Third, the failure of dry pulp therapy (hot and cold pain).
