The Gloss Retention of Esthetic Restorations Following Simulated Brushing with Charcoal Oral Products: An In-Vitro Study.

Aim: To assess the gloss and gloss retention of two esthetic restorative materials after brushing with a charcoal-infused toothbrush and activated charcoal toothpaste compared to their standard counterparts in all possible combinations.

Materials and methods: In this study,104 disc-shaped specimens were prepared, 52 from each of the two materials: Beautifil II LS composite resin (Giomer) and Fuji II LC resin-modified glass ionomer (RMGI). Specimens of each material were divided into 4 groups (n = 13) according to the tested brushing procedure: group A-standard toothbrush + standard non-whitening toothpaste (S-S), group B-standard toothbrush + activated charcoal toothpaste (S-CH), group C-charcoal-infused toothbrush + standard non-whitening toothpaste (CH-S), and group D-charcoal-infused toothbrush + activated-charcoal toothpaste (CH-CH). Gloss was recorded using a gloss meter initially and after each brushing protocol. The data were statistically analyzed with two-way analysis of variance (ANOVA) and Tukey HSD post hoc tests using SPSS® v.27 software at 5% significance level.

Results: Beautifil II LS showed the highest gloss values after brushing in group D (44 ± 3.9), which was not significantly different from its initial value (46.1 ± 1.8), followed by groups A (32.2 ± 4), B (23.2 ± 3.6), and C (22.7 ± 3.9), while Fuji II LC showed its highest gloss values after brushing in groups D (16.6 ± 3.7) and a (15.4 ± 8.7), followed by groups C (10.9 ± 6) and B (4.4 ± 2.5), all were significantly lower than their respective initial gloss values.

Conclusion: The gloss of Giomer and RMGI reduced significantly following the brushing with the tested brushing procedures except for the Giomer group brushed with a combination of charcoal-infused toothbrush and activated-charcoal toothpaste.

Clinical significance: The brushing using a combination of charcoal-infused toothbrush and activated-charcoal toothpaste is recommended for the gloss retention of Beautifil II LS restorations. However, the gloss of the Fuji II LC cannot be retained after any of the brushing procedures. How to cite this article: Farghal NS, Awadalkreem F, Abouelhonoud NA, et al.
