目的研究可吸收明胶海绵为支架,加三氧化物矿化物聚合物(MTA)封闭诱导治疗不同类型不可复性牙髓炎临床牙髓再生的可行性.方法选取临床上不可复性牙髓炎患者150例,去除冠部感染牙髓,保留根部活的牙髓,按就诊先后顺序,随机分成两组,观察组采用可吸收明胶海绵支架加MTA封闭,对照组采用氢氧化钙覆盖,观察症状转归情况,牙髓活力变化情况.结果术后半年,观察组中急性牙髓炎成功率76.5％、慢性闭锁性牙髓炎成功率47.0％,与对照组(14.3％、8.8％)差异有统计学意义(P＜0.01)；观察组中慢性增生性牙髓炎成功率33.0％、慢性溃疡性牙髓炎成功率35.0％,均高于对照组的9.1％、6.0％,但差异无统计学意义(P＞0.05).结论可吸收明胶海绵加MTA诱导体内牙髓再生是可能的,急性牙髓炎、慢性闭锁性牙髓炎牙髓再生的可能性更大.

Objective To investigate the possibility of pulp regeneration of different irreversible pulpitis with absorbable gelatin sponge as the scaffold,and dental seed cells,induced molecules and MTA closed.Methods 150 patients with irreducible pulpitis,who were removed the crown infection pulp and retained the root living pulp,according to the visiting sequence,were randomly divided into two groups.The experimental group was given absorbable gelatin sponge as the scaffold and MTA closed.The control group was given calcium hydroxide coverage.The symptoms situation and pulp situation were observed.Results 6 months after surgery,the success rate of acute pulpitis and chronic closed pulpitis in the experimental group was 76.5％ and 47.0％,which were significantly higher than those of the control group (14.3 ％,8.8％) (P ＜ 0.01).In the experimental group,the success rate of chronic hyperplastic pulpitis and chronic ulcerative pulpitis was 33.0％ and 35.0％,which were higher than those of the control group(9.1％,6.0％),but the differences between the two groups were not statistically significant (P ＞ 0.05).Conclusion Pulp regeneration in vivo is possible with absorbable gelatin sponge as the scaffold and MTA,pulp regeneration of acute pulpitis and chronic closed pulpitis are more likely to induce.
