摘要
目的:探讨纤维桩、纳米复合树脂结合氧化锆烤瓷冠对根管治疗后后牙楔状缺损患者美学效果及牙周组织的影响。方法:选取2018年1月至2019年3月期间我院收治的103例患者作为研究对象,按修复材料的不同分为对照组(n=52,患牙62颗)和研究组(n=51,患牙63颗)。对照组给予金属桩核、金属烤瓷冠修复,研究组给予纤维桩、纳米复合树脂结合氧化锆烤瓷冠修复。修复1年后,评价两组的修复成功率和修复效果。比较两组修复前及修复后1年的牙龈指数、菌斑指数、牙周探诊深度、龈沟液量及龈沟液中碱性磷酸酶(ALP)、天门冬氨酸转氨酶(AST)水平。结果:研究组的修复成功率比对照组高(P<0.05)。研究组修复体的表面光滑率、边缘密合性、固定良好率及颜色匹配率均明显高于对照组(P<0.05),两组治疗后牙龈指数、菌斑指数及牙周探诊深度均明显低于治疗前(P<0.05),龈沟液量及龈沟液中ALP、AST水平均明显低于治疗前(P<0.05),同时研究组治疗后牙龈指数、菌斑指数及牙周探诊深度均低于对照组(P<0.05),但两组治疗后龈沟液量及龈沟液中ALP、AST水平比较无差异(P>0.05)。结论:纤维桩、纳米复合树脂结合氧化锆烤瓷冠对根管治疗后后牙楔状缺损的修复成功率高,修复后美学效果佳,对牙周组织影响小。
Objective: To investigate the aesthetic efficacy and effect of fiber post, composite resin and zirconia porcelain crown on periodontal tissue in the treatment of wedge-shaped defects of posterior teeth after root canal treatment. Methods: 103 cases of wedge-shaped defects of posterior teeth after root canal treatment in our hospital from January 2018 to March 2019 were selected as the research objects, were divided into control group(n=52, affected teeth 62) and the research group(n=51, affected teeth 63) according to different restoration materials. The patients in the control group were treated with metal post core and metal porcelain crown repair, while the patients in the research group were treated with fiber post, composite resin and zirconia porcelain crown repair. The repair success rate and repair effect of the two groups 1 year after repaired were compared. The gingival index, plaque index, depth of periodontal probe, gingival crevicular fluid amount and alkaline phosphatase(ALP) and aspartate aminotransferase(AST) in gingival crevicular fluid of gingival crevicular fluid of the two groups before repaired and 1year after repaired were compared. Results: The repair success rate of research group was higher than that of control group(P<0.05). The surface smooth rate, edge tight rate, good fixation rate and color match rate of restoration of the research group were significantly higher than those of the control group(P<0.05). The gingival index, plaque index, depth of periodontal probe of the two groups were significantly lower than before treatment(P<0.05), the gingival crevicular fluid amount and ALP, AST of gingival crevicular fluid of the two groups were significantly lower than before treatment(P<0.05), and the gingival index, plaque index, depth of periodontal probe of the research group were lower than those of control group(P<0.05), but there were no significantly differences of the gingival crevicular fluid amount and ALP, AST of gingival crevicular fluid of the two groups after treatment(P>0.05).
