摘要
目的 :研究不同充填材料充填Ⅱ类洞对牙周健康的影响。方法 :分别检测银汞合金、玻璃离子粘固剂、FX、光敏复合树脂充填Ⅱ类洞 6个月后龈沟液 (GCF)量 ,龈沟液中天冬氨酸转氨酶 (GCF AST)的水平及菌斑指数。结果 :银汞、光敏充填各项指标没有明显变化 ,玻璃离子粘固剂、FX充填后GCF量、GCF AST水平及菌斑指数均有显著变化。结论
Objective: To study the effects of different restorati ve materials on the health of periodontal tissue. Methods: A total of 40 posterior teeth were divided into four groups with 10 in each. Sil ver amalgam, glass ionomer cements, GlasIonomer Cement FX and light curing Mic roglass composite resin were used to restore Class Ⅱ cavity in each tooth of th e 4 groups respectively . 6 months after restoration gingival cervical fluid (GC F) was collected , GCF aspartate aminotransferase (GCF AST) level was tested a nd plaque index was assessed for each case. Results: The s ilver amalgam and light curing Microglass composite resin groups presented less amount of GCF ( P <0.01), lower level of GCF AST ( P <0.01) and less plaque index ( P < 0.01 ) than glass ionomer cements and FX. Conclusi on: Silver amalgam is more effective and safe for the restoration of Class Ⅱcavity of teeth.
