Effect of environmentally-friendly ingredients added toothpastes on restoration materials

Abstract

Aim or Purpose: Environmentally-friendly dentistry is a concept in dentistry that aims to create an ecologically sustainable healthcare service system while preserving patients' oral-dental health and protecting planet and societal well-being. The aim of this study is to examine effect of toothpastes with environmentally-friendly ingredients added toothpastes on color and surface roughness of composite-resin restoration materials. Materials and Methods: In this in-vitro study, totally 96 composite-resin discs (8mm-diameter; 2mm-thickness) with three different brands were prepared (Charisma, Smart, Kulzer, Germany; 3M, Universal Restorative, USA; SDI-Luna, Nano-Hybrid Kompozite). At the beginning; surface roughness and color values of samples were measured using profilometer (Mahr, MarSurf PS 10) and digital spectrophotometer (VITA-Easyshade-V) as initial values. Each composite-resin group was divided into four subgroups(n=8), all the discs were brushed for ten minutes with an electronic toothbrush (Oral-B Smart) to mimic three month brushing period. Subgroups were brushed respectively; multiprotection toothpaste (Sensodyne Multi-Protection), charcoal-toothpaste (Colgate Optic White Charcoal), coffee-bean-husk-added toothpastes (as control group). Differences between and after brushing initial and brushing values of surface roughness(∆Ra) and color(∆E) were statistically analyzed using SPSS-22 programme(p<0.005). Results: The common effect of composite-resin material and toothpaste on both ∆Ra (p:0.021; p<0.05) and ∆E (p:0.001; p<0.05) levels was found statistically significant. In charcoal-toothpaste group has statistically significantly higher ∆Ra levels (p:0.013; p<0.05). It was observed that coffee-bean-husk-added toothpaste caused less color change compared to other toothpastes groups. Conclusions: All toothpastes caused certain levels of color change and/or surface roughness on composite-resin discs. Using of electronic toothbrush may also be effective in results. So that an enviromentally-friendly material such as coffee-bean-husk may be integrated into toothpastes and be used safely.
