Popis: The aim of the study was to evaluate the effects of a 2% chlorhexidine digluconate solution on the glass-ionomer cement (GIC) – dentin interface subjected to a simulated cariogenic attack. Forty extracted teeth were used in the study. On each proximal surface a box-only cavity was prepared. Each cavity was initially conditioned using GC Dentin Conditioner (GC Corp., Tokyo, Japan), then the distal cavities were pre-treated with a 2% Chlorhexidine solution. All the cavities were then restored using GIC GC Fuji IX GP Capsule (GC Corp., Tokyo, Japan). Half of the samples (n=40) were submersed in a lactic acid-based solution to simulate the cariogenic attack. The samples were then sectioned and the marginal sealing at the cervical margin was assessed by optical microscopy and scanning electron microscopy. Statistically significant differences were recorded when comparing the samples submersed in demineralizing solution with or without chlorhexidine pre-treatment vs. samples that were not pre-treated and not submersed in acid with significance levels of p=0.044 and p=0.021. In conclusion, the use of 2% chlorhexidine digluconate in dentin pre-treatment do not significantly influence the marginal sealing of glass-ionomer cements to dentin. Seven days of submersion in a lactic acid-based demineralizing solution influences the marginal adaptation of glass ionomer cements to dentin with or without 2% chlorhexidine digluconate pre-treatment.
