Report 1 describes a case of a 29-year-old patient who suffered a mandibular trauma affecting mainly the lower central incisors, caused by a car accident. A panoramic radiograph was taken right after the accident and showed a horizontal root fracture in the middle third of tooth 42, which went untreated. Report 2 illustrates a case of a 17-year-old male patient who searched for orthodontic therapy and the periapical radiograph showed horizontal root fracture in tooth 11 caused by a previous trauma, which went untreated as well. There was healing through the reestablishment of pulp activity and dental coloration without professional intervention.展开更多

目的:评价3种材料Mineral trioxide aggregate(MTA)、iRoot BP Plus和nRoot BP修复磨牙髓底穿孔的封闭能力及边缘适应性。方法:收集符合标准的恒磨牙62颗,开髓、制备髓底穿孔后随机分为3个实验组(n=18),A组(MTA组)、B组(iRoot BP Plus组...目的:评价3种材料Mineral trioxide aggregate(MTA)、iRoot BP Plus和nRoot BP修复磨牙髓底穿孔的封闭能力及边缘适应性。方法:收集符合标准的恒磨牙62颗,开髓、制备髓底穿孔后随机分为3个实验组(n=18),A组(MTA组)、B组(iRoot BP Plus组)、C组(nRoot BP)和2个对照组(n=4),D组(阳性对照组)、E组(阴性对照)。从3个实验组中各随机选4个样本用扫描电子显微镜观察髓室底与修复材料间间隙宽度。剩余样本在1%的碱性品红溶液中浸泡48 h,用染料渗透法检测评估修复部位的封闭效果。结果:A、B、C三组染料渗透差异有统计学意义(P<0.05)。MTA比iRoot BP Plus、nRoot BP的染料穿透性更大。扫描电镜下,iRootBP Plus、nRootBP与髓室底间的间隙宽度小于MTA,3组间差异有统计学意义(P<0.05)。结论:iRootBP Plus和nRootBP在修补髓底穿孔时展示了较好的封闭性和边缘适应性。展开更多
