ABSTRACT

OBJECTIVES:

The aim of the current study is to investigate the effect of different anticaries agents, such as experimental agents based on silver nanoparticles (SNPs) and silver diamine fluoride (SDF), on the micro-shear bond strength (µ-SBS) of composite resin applied to intact enamel (IE) or demineralized enamel (DE). MATERIALS AND

METHODS:

Sixty dental enamel fragments were collected from human third molars and categorized into 6 groups (n = 10) positive control (IE), negative control (DE), IE + SDF, DE + SDF, IE + SNP and DE + SNP. Samples from DE, DE + SDF and DE + SNP groups were subjected to pH cycling; superficial microhardness test was performed to confirm demineralization. Resin composite build-ups were applied to the samples (0.75-mm diameter and 1-mm height) after the treatments (except for IE and DE groups); µ-SBS was also evaluated. Samples were analyzed under a stereomicroscope at 40× magnification to identify failure patterns. Data were subjected to one-way analysis of variance, followed by Tukey's and Dunnett's tests (p < 0.05).

RESULTS:

There was no significant difference among the IE, IE + SNP, DE + SDF, and DE + SNP groups. The IE + SDF and DE groups recorded the highest and the lowest µ-SBS values, respectively. Adhesive-type failures were the most frequent for all treatments.

CONCLUSIONS:

Anticaries agents did not have a negative effect on the µ-SBS of composite resin when it was used on IE or DE.
