Surface roughness and color stability of 3D printed temporary crown material in different oral media (In vitro study)

Abstract

To evaluate the effect of different oral media (artificial saliva, carbonated orange juice and coffee) on the surface roughness and color stability of 3D printed temporary material. Methodology: twenty one discs samples were designed using additive manufacturing technique (SLA) were divided into 3 groups and stored in artificial saliva, coffee and carbonated orange juice at 37 ℃. Surface roughness was measured before and after immersion using non-contact USB Digital microscope. Color measurements were made before and after immersions using CIE L*a*b*. Data was analyzed by ANOVA followed by Tukey's pair-wise tests. Results: After two, three and twelve weeks of immersion period there was statistically significant difference between the three tested oral media groups regarding the surface roughness. The highest ΔE values were observed in the coffee (3.58, 4.40 and 10.35 ΔE) followed by Carbonated orange juice mean values (3.29, 3.84 and 7.18 ΔE) while the lowest color changes mean values were for A. Saliva immersed group (1.91, 2.29 and 2.98 ΔE) respectively. Conclusions:1. All different oral media (except A.saliva) used in the present study affected the surface roughness and the color stability of Interim discs constructed using 3-D printing technique. 2. Manufacturing of interim crowns using 3-D printing technique could be used for short-term provisional restoration. 3. This study has shown a strong positive correlation between color change and surface roughness of provisional restorative material.

Surface Roughness and Color stability of Provisional Restorative Materials Fabricated Using Different Methods After Immersion in Various Storage Media

“…In the current study the storage time significantly affected color change (ΔE) which increased, so time plays a role in the staining of provisional resin materials. This may be due to precipitation of stains over time which agreed with Radwan et al [41] and Bastos et al [42] . Where the ΔE increased progressively over time, regardless of material and media that may be due to increased water sorption over time.…”

Effect of Beverage Solutions on Surface Roughness of PEEK CAD –CAM, 3D Printing Denture Base and Heat Cure Acrylic Resin Denture Base Materials

“…The outcomes attributed to water sorption causes water to penetrate into the matrix of a 3D printing polymer structure (26) . This results was agreed with Radwan (2021) (27) ; Gad et al (2022) (28) . Acidic pH and beverage pigments such as coffee, tea, lemon juice, orange juice, red wine, and coke-based drinks have been shown to have a negative impact on acrylic resin dentures, resulting in increased surface roughness (29) .…”

Comparing the physical and mechanical properties of different biocompatible three‐dimensional resin materials in possible use of dental appliances: An in vitro study

“…Radwan et al 20 produced disc samples with SLA printer technologies and concluded that coffee has the most staining effect on the examined 3D‐printed materials. Çakmak et al 21 conducted a study to compare the effect of tooth brushing and thermal cycling on the colour stability of 3D printing denture base resins (Next Dent, Denturetect, Polident, Promolux).…”
