不同粘结剂对种植体周围龈沟液pH值影响的临床研究
Clinical trial of effects of different cements on the pH of peri-implant crevicular fluid
摘要
Abstract
Objective To investigate the influence of two kinds of different cements (resin-reinforced glass ionomer and self-adhesive resin cement) to the pH of peri-implant crevicular fluid of cement retained implant restorations.Methods About 15 patients for cement retained implant restorations with a total of 30 dental implants were chosen for study.The implants were randomly divided into two groups,treatment group for the resin-reinforced glass ionomer,and control group for the self-adhesive resin cement,with 15 implants in each group.Another 15 patients were chosen to observe 1 healthy tooth and periodonatal tissue from each of them as blank group.The pH of peri-implant crevicular fluid and meliorate plaque index were measured respectively before the crowns were bonded,after 6 months and 12 months.The measured results during different periods were compared.Results Before the crowns were bonded,after 6 months and 12 months the pH of peri-implant crevicular fluid of treatment group were (7.19 ± 0.47),(7.30 ± 0.51),(7.38 ± 0.55),meliorate plaque index were (0.43 ± 0.35),(0.51 ± 0.36),(0.54 ± 0.45);the pH of peri-implant crevicular fluid of control group were (7.20 ± 0.55),(7.39 ± 0.48),(7.85 ± 0.53),meliorate plaque index were (0.42±0.41),(0.53 ± 0.45),(0.92 ± 0.59);the pH of gingival crevicular fluid of blank group were (7.21 ±0.52),(7.22 ±0.55),(7.29 ± 0.49),meliorate plaque index were (0.44 ±0.35),(0.48 ±0.25),(0.50 ± 0.46).Tweleve months after the crowns were bonded,pH of gingival crevicular fluid and meliorate plaque index in control group were significantly higher than that in treatment group and blank group.There was a positive correlativity between meliorate plaque index and pH of gingival crevicular fluid.Conclusion Resin-reinforced glass ionomer has less effect on the pH of peri-implant crevicular fluid.关键词
