The effect of porcelain laminate veneers on gingival health and bacterial plaque characteristics.

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.
