Oral biofilm and caries-infiltrant interactions on enamel

Adhesive performance of a caries infiltrant on sound and demineralised enamel.

OBJECTIVE Resin infiltration is considered as a treatment option for initial caries lesions. As cavitated early lesions might require additional restorative intervention, a caries infiltrant might be also used for enamel conditioning prior to composite insertion. This study aimed to analyse the shear bond strength of a flowable composite to sound and demineralised enamel pretreated with a carie...

Caries infiltrant combined with conventional adhesives for sealing sound enamel in vitro.

OBJECTIVE To test the null hypothesis that combining low-viscosity caries infiltrant with conventional adhesive resins would not improve sealing of sound enamel against demineralization in vitro. MATERIALS AND METHODS Bovine enamel discs (N = 60) with diameter of 3 mm were randomly assigned to six groups (n = 10). The discs were etched with 37% phosphoric acid for 30 seconds and treated with ...

Laser and enamel resistance to caries

Effects of different antibacterial agents on enamel in a biofilm caries model.

Using a mature biofilm model, the aim of this study was to evaluate the effectiveness of different antibacterial agents in comparison with silver diamine fluoride (SDF). Forty-eight saliva-coated enamel slabs were inoculated with Streptococcus mutans monospecies biofilm. The biofilms were then exposed to 10% sucrose in tryptone yeast-extract culture medium, 8 times per day for 7 days. After the...

The effect of resin infiltrant (Icon), MI paste plus and Nd:YAG laser on enamel microhardness

Background and Aims: Erosion is the chemical dissolution of a tooth by acid without bacterial involvement. The purpose of the current study was to investigate the effect of resin infiltration (Icon), MI paste plus, and Nd:YAG laser on the enamel microhardness. Materials and Methods: 40 enamel samples were obtained from the third molar tooth. Primary microhardness was measured in all specimens....
