目的：观察 MTA 与氢氧化钙直接盖髓在年轻恒前牙外伤治疗中的效果。方法选取我院40例年轻恒前牙因外伤而意外露髓患者随机分成两组，分别将 MTA 及氢氧化钙作为手术治疗中的盖髓剂进行治疗，并在术后6个月、1年、2年及3年进行复查，分析评价疗效。结果术后6个月、1年后复查，MTA 组治疗效果与氢氧化钙组相似，差异在统计学上没有可比性（P ＞0.05）；术后2年、3年进行复查， MTA 组治疗效果明显优于氢氧化钙组，两组治疗效果有显著性差异，有统计学意义（P ＜0.05）。结论年轻恒前牙外伤治疗中，盖髓剂应优先选择 MTA，MTA 的远期治疗效果明显优于氢氧化钙。

Objective MTA observed with calcium hydroxide direct pulp capping effect of trauma in young permanent teeth before treatment. Methods Our hospital 40 cases of young permanent teeth due to trauma and accident exposed pulp were randomly divided into two groups, namely, the MTA and calcium hydroxide as the surgical treatment of capping agent for treatment and after 6 months, 1 year, 2 years and 3 years for review, analysis and evaluation of efficacy. Result After six months, one year after the review, MTA treatment groups were similar with calcium hydroxide, the difference was not statistically comparable (P>0.05); after 2 years, 3 years for review, MTA group treatment significantly better than the calcium hydroxide group, the two groups there was a significant treatment effect difference was statistically significant (P<0.05). Conclusion MTA is a good kind of drug in pulpotomy for the young permanent teeth,and its clinical effects are better than those of calium hydroxide,and it is worthwide application.
