摘要
目的:评估年龄对年轻恒牙根尖周病牙髓再生潜力的影响。方法:选取30例年龄9~18岁患者的伴牙髓坏死的下颌前磨牙,分成2组,9~13岁为A组(年轻组),14~18岁为B组(年长组)。2组患牙均采用根管内血运重建术,于术后6、12、18个月随访,利用锥形束CT(CBCT)监测2组患牙的牙根长度、根管壁厚度。采用SPSS13.0软件包对数据进行非参数两样本秩和检验。结果:随访18个月,2组病例术后炎性症状均消失,均为有效病例。影像检查结果分析显示,A组牙根长度和根管壁厚度较B组显著增长(P<0.05)。结论:根管内血运重建术可广泛用于年轻恒牙牙髓坏死的治疗,年龄越接近患牙的萌出时间,其牙髓再生潜力越高,越适宜根管内血运重建治疗。
PURPOSE： To evaluate the effect of age on the potential of dental pulp regeneration in young permanent teeth with periapical periodontitis. METHODS： A total of 30 mandibular premolars from 9-18 years old patients with pulp necrosis were divided into 2 groups, group A （younger age group）： 9-13 years old, and group B （older age group）： 14-18 years old. Revascularization procedures were performed for all patients. Follow-up was done for up to 18 months. Standardized radiographs of cone-beam CT （CBCT） were digitally evaluated for increase in root length and thickness. The data were analyzed by nonparametric two sample rank sum test using SPSS13.0 software package. RESULTS： After 18 months of follow-up, the clinical symptoms of the two groups disappeared. The cure rate of group A was significantly higher than that of group B （P=0.003）. Radiographic analysis showed that the root length and root canal wall thickness in group A was significantly greater than those in group B （P〈0.05）. CONCLUSIONS： Root canal revascularization can be widely used in the treatment of dental pulp necrosis in young permanent teeth. The closer the age is to the eruption time, the higher the potential of dental pulp regeneration, and the more suitable for root canal revascularization.
