Objective To compare the influence of indirect method Geramage polymeric porcelain veneer restoration and direct method light curing resin veneer restorationon periodontal related index. Methods A toatl of 82 patients (a total of 222 teeth) for prescription of the live pulp front teeth were selected, and divided into observation group (41 patients, 118 teeth) and control group (41 patients, 104 teeth) according to random number table method. The observation group was treated with indirect method Geramage polymeric porcelain veneer restoration, and the control group was treated with direct method light curing resin veneer restoration. The integrity, edge coloring, color matching with neighboring teeth, edge suitability, dental pulp state and abutment sensitivity of restorations, the plaque index (PI), gingival index (GI),depth of gingival sagittal (PD), gingival crevicular fluid volume (GCF), interleukin-1α (IL-1α) in gingival crevicular fluid at 1 year after repair were compared between two groups. Results There were no significant difference in the success rate of the integrity, dental pulp state and abutment sensitivity of restorations at 1 year after repair in two groups (P>0.05). The success rate of edge coloring, color matching with neighboring teeth, edge suitability were 97.46%, 98.31% and 97.46%, respectively, which were significantly higher than 91.35%, 90.38%, 89.42% in the control group (P<0.05).The score of PI, GI and the levels of GCF and IL-1α were (1.30±0.5 7),(0.09±0.11),(1.87±0.57) mg, (69.32±8.17) ng/ml, which were significantly lower than (1.48±0.6), (0.32±0.14), (2.35±0.69)mg,(75.03±7.65) ng/ml in control group (P<0.05). Conclusion The indirect method Geramage polymeric porcelain veneer restoration can better reproduce natural tooth shape,smooth surface, color and stability, with the adjacent tooth color match,the edge of a good fit. And less prone to edge micro-infiltration, to avoid edge staining and plaque accumulation,the gums and periodontal tissue health was more favorable.%目的:对比间接法Geramage聚合瓷贴面修复体和直接法光固化树脂贴面修复对牙周相关指标的影响.方法:选取82例(共222颗患牙)行活髓前牙美容的患者,按随机数表法分为观察组41例(共118颗患牙)与对照组41例(共104颗患牙).观察组采取间接法Geramage聚合瓷贴面修复,对照组采取直接法光固化树脂贴面修复.比较两组修复1年后的修复体完整度、边缘染色、与邻牙颜色匹配度、边缘适合性、牙髓状态及基牙敏感程度,菌斑指数(PI)、牙龈指数(GI)、龈沟探诊深度(PD)、龈沟液量(GCF)、龈沟液中白介素-1α(IL-1α)浓度.结果:两组患者修复后1年,修复体完整度、牙髓状态及基牙敏感程度的成功率比较,差异无统计学意义(P>0.05).观察组边缘染色、与邻牙颜色匹配度、边缘适合性的成功率分别为97.46%、98.31%、97.46%,显著高于对照组91.35%、90.38%、89.42%,有统计学意义(P<0.05).观察组修复牙的PI、GI评分、GCF与IL-1α分别为(1.30±0.57)分、(0.09±0.11)分、(1.87±0.57)mg、(69.32±8.17)ng/ml,显著低于对照组(1.48±0.6)分、(0.32±0.14)、(2.35±0.69)mg、(75.03±7.65)ng/ml(P<0.05).结论:间接法Geramage聚合瓷贴面修复可较好地再现天然牙形态,表面光滑,色泽稳定,与邻牙颜色匹配、边缘适合性好,且不易发生边缘微渗透,可避免边缘染色与菌斑堆积,对牙龈及牙周组织的健康更为有利.
