Surface degradation effects of carbonated soft drink on a resin based dental compound

Abstract

Dental compounds and restorative materials undergo surface degradation and erosion from exposure to a variety of dietary substances. In this study we investigated changes in the surface properties of Rebaron, a hard denture reline material (HDRM), following timed immersion in carbonated soft drinks to determine its durability in a common acidic environment. Samples were prepared and immersed in a carbonated soft drink (or its components) for 6, 12, or 24 h. Surface structure and mechanical properties were characterized using Atomic Force Microscopy (AFM). Raman spectroscopy was used to identify changes in the HDRM surface chemistry following exposure to the test solutions. AFM revealed that prolonged exposure led to pit formation and a subsequent increase in surface roughness, from 302.02 ± 30.20 to 430.59 ± 15.07 nm Ra, following a 24 h exposure. Young's modulus values decreased from 9.3 ± 7.0 to 0.53 ± 0.26 GPa under the same conditions, demonstrating a softening and embrittlement of the HDRM sample. Raman results revealed that immersion in the carbonated soft drink or acidic solution changed the nature of the HDRM structure, converting the HDRM surface chemistry from primarily hydrophobic to hydrophilic. Our study indicates that sustainability and durability of Rebaron HDRM are significantly reduced by prolonged exposure to carbonated (acidic) soft drink, resulting in deformation and degradation of the material surface.

Effects of various beverages on characteristics of provisional restoration materials

“…Rather, the present report evaluated the color, hardness, and roughness of the four specific materials used. It would also be interesting in the future to observe either microstructure and/or chemical composition (Tseng et al, 2021 ) after these materials have performed under different beverages.…”

Polymerization Shrinkage, Hygroscopic Expansion, Elastic Modulus and Degree of Conversion of Different Composites for Dental Application

“…In this wet condition, the initiation of the crack/flaw is then facilitated, requiring little effort, such as stresses generated after polymerization shrinkage. Consequently, the adhesion of the particles to the matrix can be destroyed by hydrolysis [52][53][54][55][56][57]. If the material is inhomogeneous and anisotropic, as almost all dental materials are, several sizes of defects can be present [58].…”

“…If the material is inhomogeneous and anisotropic, as almost all dental materials are, several sizes of defects can be present [58]. This potential deterioration of the glass is one of the reasons why it is so important to form an organic layer of silane molecules on the surface of the filler to protect it from the environment [56][57][58]. No matter what the application or the chemistry of the polymer present in the resin cements, the properties investigated in this study show that future studies are needed considering composite integrity.…”

Impact of acidic beverages on esthetic restorations concerning microhardness and color stability: a comparative assessment

“…They are especially well suited for the repair of cavities with intricate anatomical structures or hard-to-reach places when using conventional composite materials because of this property. Lately, high and flowable consistency bulk-fill resin-based composite restorative materials have gained popularity owing to their simple strategy of application, which was different from the regular composite resins (Tseng et al 2021). Also, they can be embedded in a single layer of 4mm, unlike regular composite resins.…”
