■根管系统的三维液密闭塞结束了牙髓治疗过程,根管(RC)闭塞的技术质量是治疗结果的决定因素。RCT的最后阶段对治疗结果至关重要,因此需要有足够和质量的封闭。对学生在这方面的表现进行审计,评估表现,并确定需要改进的地方。因此,我们着手评估本科和研究生临床牙科学生进行根管闭塞的质量。
■一项横断面研究,评估了教学医院的本科生和研究生进行的根管闭塞,1年。射线照相评估由校准的评估员完成。在放大镜(x3.5)下观察X射线照片。在18岁及以上的患者中,在所有治疗类别的牙齿中评估的结果变量是闭塞的长度和密度的均匀性。在研究期间看到的。
■97例患者的84颗上颌和36颗下颌牙齿进行了根充,平均年龄为37.6岁±14.7SD。很大一部分(47.5%)的根填充物是由研究生医生完成的。大多数运河(69.4%)具有可接受的长度,而密度仅为37.7%。据报道,在单根根管(p=0.000)的牙齿中,长度可接受的根管略多于一半(127个;50.4%),密度相同(28个;40.6%)。总体可接受长度和根填充密度为28.9%,并且与根填充长度相关的操作员的性能没有统计学意义(p=0.109),和密度(p=0.55)。
■本科生和研究生的总体可接受长度和根系填充密度为28.9%。根管充填的充分性可能取决于经验,牙齿的复杂性,和仪器的方法。
UNASSIGNED: the three-dimensional fluid-tight obturation of the root canal system ends the endodontic treatment process and the technical quality of obturation of the root canal (RC) is a determinant of the outcome of the treatment. This final stage of RCT is critical in the outcome of treatment, thus the need to have adequate and quality obturation. The audit of the performance of students in this aspect evaluates performances and identifies where there is a need for improvement. Therefore, we set out to evaluate the quality of root canal obturation performed by undergraduate and postgraduate clinical dental students.
UNASSIGNED: a cross-sectional study that evaluated the root canal obturation performed by undergraduate and postgraduate students in a teaching hospital, for 1 year. The radiographic evaluation was done by calibrated assessors. The radiographs were viewed under magnifying lenses (x3.5). The adequacy of length and homogeneity of the density of obturation were the outcome variables assessed in all the categories of teeth treated among patients who are 18 years and above, seen during the study period.
UNASSIGNED: eighty-four maxillary and 36 mandibular teeth were root-filled in 97 patients with a mean age of 37.6 years ± 14.7 SD. A good proportion (47.5%) of the root fillings were done by the postgraduate doctors. Most of the canals (69.4%) had acceptable lengths while density was acceptable in only 37.7%. Slightly over half of canals with acceptable length (64 out of 127; 50.4%) were reported in teeth with single canals (p=0.000) likewise with density (28;40.6%). Overall acceptable length and root filling density was 28.9% and there was no statistical significance in the performances of the operators in relation to the length of root filling (p=0.109), and density (p=0.55).
UNASSIGNED: the overall acceptable length and root filling density was 28.9% among both undergraduate and postgraduate students. The adequacy of root canal filling may be dependent on experience, the complexity of the tooth, and the method of instrumentation.
