ABSTRACT
Objective:
To explore the effects of different full-crown materials on the periodontal tissues.Methods:
120 defected teeth were restored by full-crown with Ni-Cr alloy,Co-Cr alloy and all ceramic respectively(n =40).Periodontal clinical examination (include SGI,PLI,PD)and PCR detection of Porphyromonas gingivalis(Pg),Actinobacillus actinomycetemcomitans(Aa),Prevotella intermedia(Pi)and Fusobacterium nucleatum(Fn)in subgingival plaque of the abutment teeth were performed before and after restora-tion.Results:
6 -24 months after restoration SGI,PLI and PD of Ni-Cr and Co-Cr groups were increased(P 0.05).12 months after restoration the detection rate of periodontal pathogens of Ni-Cr and CO-Cr groups was higher than that of all ceramic group(P <0.05).Conclusion:
All ceramic is superior to Co-Cr and Ni-Cr in crown resto-ration for periodental tissue.
