摘要
目的:评价不同充填方法对楔状缺损美容修复的疗效及对牙周组织健康的影响。方法:83例上颌前磨牙缺损患者,按简单随机法分为对照组(n=40)和治疗组(n=43),牙数分别为58颗和64颗,对照组采用树脂改性光固化玻璃离子充填修复,治疗组采用纳米光固化复合树脂充填。比较两组修复后成功率,改良的美国公共卫生服务评价体系(United states public health service,USPHS)分级评价疗效,比较修复前后临床牙周检查和牙周生化指标。结果:两组修复后1年成功率比较,差异无统计学意义(P>0.05),修复后2年,治疗组成功率高于对照组,差异有统计学意义(P<0.05)。修复后12个月,两组色泽协调性、边缘着色、边缘密合性、表面结构、继发龋、牙髓反应及比较差异无统计学意义(P>0.05)。修复前,两组菌斑指数、龈沟出血指数、探诊深度、龈沟液量、碱性磷酸酶(alkaline phosphatase,ALP)、天门冬氨酸转移酶(aspartate transferase,AST)比较差异无统计学意义(P>0.05);修复后,两组龈沟出血指数、探诊深度、龈沟液量、ALP、AST均较治疗前上升,治疗组低于对照组,差异有统计学意义(P<0.05)。结论:树脂改性光固化玻璃离子和纳米光固化复合树脂充填修复楔状缺损均可起到良好的效果,但后者远期美容修复疗效更佳,在减轻龈下牙周组织损伤方面更具优势。
Objective To evaluate the effect of different filling methods on cosmetic repair of wedge-shaped defect and the effect on periodontal tissue health.Methods 83 patients with maxillary premolar defects were randomly divided into the control group (n=40) and the treatment group (n=43),the number of teeth was 58 and 64.The success rate,the improved US Public Health Service Evaluation System (USPHS) classification,and the clinical periodontal examination and periodontal biochemical indicators before and after repair of the two groups was compared.Results There was no statistically significant difference in success rate between the two groups at 1 year after repair (P>0.05),2 years after repair,the success rate of the treatment group was higher than that of the control group (P<0.05).At 12 months after restoration,there were no significant differences in color coordination,edge staining,edge adhesion,surface structure,secondary caries,pulp reaction and comparison between the two groups (P>0.05).Before repair,there were no significant differences in plaque index,gingival sulcus bleeding index,depth of diagnosis,amount of gingival sulcus fluid,alkaline phosphatase (ALP) and aspartate transferase (AST) between the two groups (P>0.05).After the repair,the index of gingival crevicular hemorrhage index,probing depth,gingival crevicular fluid volume,ALP and AST of the two groups all increased compared with that before treatment,and the treatment group was lower than the control group,with statistically significant differences (P<0.05).Conclusion Resin-modified uv-cured glass ion and nano-uv-cured composite resin filling can achieve good results in repairing wedge-shaped defects,but the latter has better efficacy in long-term cosmetic repair and has more advantages in reducing subgingival periodontal tissue damage.
