摘要
目的;探讨三种不同金属烤瓷全冠修复体对患牙龈下菌斑中Pg、Aa检出率及牙周指数的影响。方法:收集进行镍铬合金烤瓷全冠、钯银合金烤瓷全冠,金合金烤瓷全冠修复的患者各30例,修复后6个月复诊,比较修复前、后患牙龈下菌斑中Pg、Aa检出率及各项牙周指数的差别。结果:镍铬合金烤瓷全冠修复6个月后患牙PD、SBI增大(P<0.05),PLI与修复前无差别(P>0.05)。钯银合金烤瓷全冠、金合金烤瓷全冠修复6个月后PD增大(P<0.05),PLI、SBI均与修复前无差别(P>0.05)。镍铬合金烤瓷全冠修复后患牙龈下菌斑中Pg检出率升高,Aa检出率无改变,钯银合金烤瓷全冠、金合金烤瓷全冠修复前、后Pg、Aa检出率无改变。结论;钯银合金烤瓷全冠、金合金烤瓷全冠修复对患牙牙周指数、龈下菌斑中Pg、Aa检出率影响不明显。
Objectives： To explore the influence of three metal ceramic crown restoration on the subgingival plaque in Pg and Aa positive rate of restored tooth and the effect of periodontal index. Methods：Collect each of the 30 patients who was placed the Ni - Cr alloy porcelain ,the Pd - Ag alloy porcelain crown, and the Gold alloy porcelain erown, Through the comparison of the changes of all periodontal index between patient＇s first visit and 6 months＇ later, and restored teeth＇s subgingival plaque were collected for detecting the changes of the positive rates of Pg and Aa. Results：six months after Ni - Cr alloy porcelain crowns were. placed,PD and SBI were higher （ P〈 0.05） ,PLI were the same as the first visit, subgingival plaque in Pg positive rate increased, the positive rate of Aa without change;while to the Pd - Ag alloy and the Gold alloy,PD were higher, SBI and PLI had no difference from the first visit, subgingival plaque in Pg positive rate and the positive rate of Aa without change. Conclusion： After 6 months the placement of the Pd- Ag alloy porcelain crowns restoration and the Gold alloy porcelain crowns restoration, they had little influence on the periodontal index of restored tooth and the detection frequency of the restored teeth＇ s subgingival plaque.
