Abstract
Objective To compare the impact of complete crowns made by three different materials on the gingival health and pigmentation. Methods Forty patients were selected randomly and divided into three gr,oups:metal-ceramic crowns of Ni-Cr alloy;metal -ceramic crowns of Pd-Ag alloy; and zirconia all-ceramic crowns.After1,2 and 3 years follow up, the marginal gingival bleeding index and pigmentation were examined. The data were analyzed by SPSS 13.0 software. Results Givngival inflammation or pigmentation was observed in 15 cases of Ni-Cr group.Two cases of Pd-Ag alloy metal-ceramic crowns with discolored gingivae were observed. No gingival inflammation or pigmentation was observed in zirconia all-ceramic group. Conclusion The metal-ceramic crowns of Pd-Ag alloy and zirconia all -ceramic crowns showed good biocompatibility. There were no adverse effects of all-ceramic crowns on gingival health. The Pd-Ag alloy metal ceramic crowns would not cause obvious harm to the marginal gingival, while the Ni-Cr alloy metal ceramic crowns may increase the risk of gingival bleeding and pigmentation.关键词
