Abstract：
UNASSIGNED: There are numerous chances for pulpal irritation during the placement of a crown on a tooth. This study\'s goal was to find and examine the variables that influence the prevalence of routine root canal therapy after the teeth were restored with full coverage crowns.
UNASSIGNED: The hospital records were retrospectively evaluated from 2000 to 2010 for a decade. The demographics as well as the various variables that caused for the intervention with the root canal therapy for the teeth with the full crowns were evaluated. The values were compared for the significance.
UNASSIGNED: The total number of the teeth that were finalized in the study was 4308. Of the total teeth that were treated with full coverage crowns, 50% were metal ceramic, 42% were full ceramic, and 9% were full metal crowns. After 10 years, possibility that every tooth with a crown would survive was 91%. The most frequent adverse incident was the intervention with the RCT. Metal ceramic crowns had poor survival rates and needed the maximum intervention. Younger age-group had least survival rate than the older age-groups.
UNASSIGNED: Endodontic therapy is unlikely to be necessary after crown installation. As the patient\'s age declines and all-ceramic or PFM crowns are used, this risk rises.

摘要：
■在将牙冠放置在牙齿上时，牙髓有很多刺激的机会。这项研究的目的是发现和检查影响常规根管治疗的患病率的变量后，牙齿恢复全覆盖冠。
■从2000年到2010年十年的医院记录进行了回顾性评估。评估了人口统计信息以及对全冠牙齿进行根管治疗干预的各种变量。比较这些值的显著性。
■研究中最终确定的牙齿总数为4308。在用全覆盖冠治疗的总牙齿中，50%是金属陶瓷，42%是全陶瓷，9%是全金属冠。十年后,每颗带冠的牙齿存活的可能性为91%。最常见的不良事件是RCT干预。金属陶瓷冠的成活率较差，需要最大程度的干预。年轻年龄组的生存率低于老年组。
■牙髓治疗在牙冠安装后不太可能是必要的。随着患者年龄的下降和全瓷或PFM冠的使用，这种风险上升。
