The aim of this study was to evaluate the response of microbial plaque and gingival inflammation to the placement of porcelain laminate veneers on anterior teeth. 9 patients, 7 female and 2 male (mean age of 30 years), with a total of 35 veneers were examined. The volume of gingival crevicular fluid (GCF), level of neutral proteolytic enzyme activity, gingival index (GI), plaque index (PlI) and plaque bacteria vitality were measured at baseline and after the placement of veneers. The volume of GCF increased after the placement of veneers (p = 0.03). No statistically significant differences were found in proteolytic enzyme activity or GI (p > 0.05). There were statistically significant reductions in PlI (p = 0.000) and plaque bacteria vitality (p = 0.018). Further research is required to assess the long-term influence of porcelain laminate veneers on gingival health and microbial plaque characteristics.
本研究的目的是评估在前牙上放置瓷贴面后微生物菌斑和牙龈炎症的反应。对9名患者（7名女性和2名男性，平均年龄30岁）共35颗贴面进行了检查。在基线和放置贴面后测量龈沟液（GCF）体积、中性蛋白酶活性水平、牙龈指数（GI）、菌斑指数（PlI）和菌斑细菌活力。放置贴面后GCF体积增加（p = 0.03）。在蛋白酶活性或GI方面未发现统计学上的显著差异（p > 0.05）。PlI（p = 0.000）和菌斑细菌活力（p = 0.018）有统计学上的显著降低。需要进一步研究来评估瓷贴面在牙龈健康和微生物菌斑特征方面的长期影响。
