| 目的：研究保存牙髓对牙根未发育成熟的全脱位恒牙再植预后的影响。方法：选择因外伤来院就诊的全脱位恒牙26颗,干燥保存,离体时间在1h～2h之间。试验组为13颗根尖孔未闭合的年轻恒牙,使用生理盐水冲洗完全脱位牙及牙槽窝,局麻下复位,树脂夹板固定,调(牙合),2周后拆除固定装置。对照组为13颗根尖已经闭合的恒牙,复位固定一周后进行常规牙髓治疗,Vitapex糊剂充填。6个月后更换一次糊剂。所有病例每三个月拍摄牙片,观察评价牙根吸收程度。随访18个月后。根据牙根是否发生炎症性吸收评价治疗是否成功。采用SPSS13.0软件包对数据进行统计学分析。结果：再植后18个月,实验组成功率为46.2%,对照组成功率为84.6%,两组差异具有统计学意义(P<0.05)。结论：对于保存条件差,离体时间长的根尖未闭合全脱位恒牙,建议复位固定一周后应采用常规牙髓治疗,充填Vitapex糊剂,以减轻髓腔内及根尖区炎症反应,促进牙本质桥形成,诱导根尖发育。 |

| Objective: To evaluate the result of immature avelsed teeth after replanted by reservation of pulp. Methods: 13 avulsed anterior teeth with no fully developed apices which were reserved in dry condition between an hour two were enrolled in this study. For each case,the tooth and its alveolar site were irrigated with 0.9% NaCl,then the tooth was put into its original site and fixed with resin splint,selective grinding to avoid premature contact. Another 13 avulsed permanent teeth were also enrolled a control group.The inclusion criteria and emergency treatment were the same as study group, One week later,the teeth in control group. The inclusion criteria and emergency treament were the same as study group. One week later,the week later,the teeth in control group. The inclusion criteria and premature contact.Another 13 avulsed permanent teeth were also enrolled a control group. The inclusion criteria and emergency treatment were the same as study group. One week later,the teeth in control group underwent root canal treatment.But root canal would be filled by Vitapex paste in stead of gutta-percha point. All the patients were asked to recall every three months,X-ray film was taken to evaluate root absorption. Vitapax paste as the temporary root canal filling material was repalced every six months. Whether the treatment was successful or not was depend on the root absorption. Statistical analysis was carried out using SPSS13.0 software package. Results: The success rate of two groups was significantly different,which was higher 18months after treatment in Control group than Study group(84.6% vs 46.2%). Conclusions: To these miiayure avulsed teeth which were reserved in dry condition over an hour,we suggest that the tooth should be put into its original site and fixed immediately,then removed the pulp,filled with Vitapax paste in one week. In the week,the purpose was to relieve inflammatory reaction in pulp cavity and around root apex area. Further more it could dentine bridge and root apex form. |
