Effect of mouthrinses on surface roughness and of a nanofilled restorative composite

Abstract

<p><strong>Objective:</strong> The aim of this study was to evaluate the effect of mouthrinses on the surface roughness of the nanofilled restorative composite. <strong>Material and Methods</strong>: Twenty discs (4 mm in diameter and 1 mm in height) of the composite Filtek Z350 were made and roughness (µm) was measured using perfilometer with a 0.5 μm diamond needle tip measuring and accuracy of 0.01 μm. The discs were randomly divided into four groups (n=5): Control (distilled water), G1-Plax, G2-Plax Whitening e G3-Listerine and individually storage in eppendorfs with distilled water at 37°C. The specimens were maintained in distilled water during 30 d and immersed in mouthrinses every 12 h for 1 min. after the 30 d the specimens was cleaned in distilled water, storage in oven at 37°C during 24 h and the surface roughness test was repeated with the same parameters previously described. The data were submitted to Two-way ANOVA and the t-studant test for paired specimens. <strong>Results</strong>: No significant differences among groups were detected R1: Control (0.12±0.04); G1 (0.13±0.05); G2 (0.11±0.03); G3 (0.11±0.02); and R2: Control (0.16±0.04); G1 (0.15±0.02); G2 (0.13±0.01) e G3 (0.15±0.02).<strong> Conclusions</strong>: In this study the mouthrinses solutions did not promote significant changes on the surface roughness of Filtek Z350 after 30 d.</p><p><strong>Keywords</strong>: Composites; Polymer; Dental materials</p>

Effect of Different Fluoridated Mouth Rinses on the Surface Characterization of Nano-Filled Resin Composite Materials

“…In general, the results of the current study revealed significant differences when using Colgate Plax and Listerine as medium mouthwashes. These results are contrast with that found by Urbano et al (18) in which no significant differences were detected among Plax alcohol free, Plax whitening, and Listerine mouthwashes. Another study 22 also found no significant difference when alcohol Oral B mouthwash was used.…”

Evaluation of mouth rinses on degradation and hardness of dental nano-composite

“…Also other properties such as tensile testing and colour stability may be conducted to provide more specific data about the effects of pH and alcohol concentration of various solvents on esthetic restorative materials. 22 …”

The Effect of Mouthrinses on Surface Roughness of Two Nanohybrid Resin Composites

“…The effects of mouthrinses on color, microhardness, microleakage, water absorption, and solubility of resin composites have been investigated in many studies, but there are few studies evaluating the effect of mouthrinses on the surface roughness of resin composites [9][10][11][12]. These few studies mostly have concentrated on microhybrid, hybrid, or nanofilled resin composites, and have differing conclusions.…”
