查询词典 pulpless

The follow-up periods were various from 6m to 21m. The apical MTA barrier technique was used to manage pulpless permanent teeth with incomplete root formation. The postoperative radiographs showed complete repair of periradicular tissue in 5 of 7 teeth and improvement obviously in other 2 teeth. Only one case (1 tooth) had a 3mm periodontal pocket in four perforation repair cases. The lesion at the perforation sites was improved obviously.

追踪观察时间为6-21月。4例穿孔修补的病例，均为延迟修补，除一例为根尖1／3处的病理性吸收外，其余患牙的穿孔部位位于牙根的冠1／3或根分叉处，一例6m复查时有3mm的牙周袋形成，其余患牙骨吸收暗影均明显缩小。7例根尖发育不全并无髓牙的病例均为成人，5例根尖暗影完全消失，2例明显缩小。

MTA was used to manage clinical problems. These included pulpless permanent teeth with incomplete root formation and perforation in roots or furcations. Total 10 cases (12 teeth), former 7 cases (7 teeth) and latter 4 cases (5 teeth), were present. The follow-up periods were various from 6m to 21m.

应用免疫组织化学手段，观察细胞外非胶原蛋白骨唾蛋白（bonesialoprotein，BSP）、骨桥素（osteopontin，OPN）和骨钙素（osteocalcin，OC）在根尖周组织愈合期间的表达，尤其是在与倒充填材料直接相邻区域的表达。

Maxillary central incisors had a slightly greater pulpal blood flow values than maxillary lateral incisors. The flow values from 15 teeth with necrotic pulp or pulpless teeth were significantly lower than that from the control teeth. Before therapy the values from 16 deep caries teeth were all higher than that from the control teeth. After therapy, most (15/16) of those values decreased to normal in three days. The value of one tooth with deep caries remained high, and one week later, the pulp became necrosis.

由死髓牙测得的流量值显著小于正常对照。16颗深龋患牙治疗前牙髓血流量皆高于正常对照组，治疗后有15颗患牙的血流量很快降至正常，有1颗患牙在治疗后血流量无明显变化，最终发生牙髓坏死。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
