目的探讨二氧化锆全冠修复早期隐裂牙保存活髓疗效情况。方法 100例隐裂牙患者,依据治疗措施不同进行分组,对照组(金属烤瓷全冠修复组)和观察组(二氧化锆全冠修复组),各50例。结果观察组隐裂牙患者临床治疗的总有效率明显高于对照组,观察组隐裂牙患者的牙龈变色、牙龈炎的发生率均低于对照组,差异均有统计学意义(P<0.05)。结论二氧化锆全冠修复早期隐裂牙保存活髓效果明显,不良反应少,值得临床推广应用。
Objective To investigate the effect of zirconium crowns on the preservation of vital pulp in patients with early cracked teeth. Methods One hundred patients with occult tooth were divided into groups according to the different treatment measures. The control group (PFM crown restoration group) and the observation group (zirconium dioxide crown restoration group), 50 cases each. Results In the observation group, the total effective rate of clinical treatment was significantly higher than that of the control group. The gingival discoloration and gingivitis in the observation group were lower than those in the control group (P <0.05 ). Conclusion Zirconia crown restoration of early hidden tooth preservation vivid pulp obvious effect, fewer adverse reactions, worthy of clinical application.
