Evaluation of Some Exogenous Colorants Effects on Resin Based Materials Used in Incipient Caries Lesions Therapy

Abstract

The aim of this study was to evaluate the potential of coloring of two commercial beverages: coffee and wine, and cigarette smoke, on three materials (ICON infiltration resin, MI Varnish Recaldent, and a sealant based on composite resin) currently used in incipient caries therapy. The study group included 75 extracted teeth that were divided into 3 groups corresponding to each material used. The groups were divided into 5 subgroups that corresponded to each colorant (A. red wine, B. coffee, C. cigarette smoke, D. association of the three colorants, E. control group). The coloration degree of the samples was measured both after the moment of coloring (M3) and after polishing (M4). The results showed a significant increase of the coloring degree for the samples subjected to the combined action of the three colorants (M3), for all the three materials used (DE1*: Id = 23.56, IId = 25.87, IIId = 19.87), and in terms of the coloring degree after the polishing procedure (M4), a decrease of the values was observed (DE2*: Id = 17.56, IId = 21.67, IIId = 16.78). In conclusion, both exposure to the two beverages used in the study and cigarette smoke (C) leads to the appearance of color changes, but the most significant changes were obtained by combining the three colorants (D). Also, the polishing procedure leaded to an improvement of the color variation for all three materials.

Effect of tobacco and nicotine in causing staining of dental hard tissues and dental materials: A systematic review and meta‐analysis

“…Five studies assessed the effect of cigarette smoke on resin composite (Figure 3 ) (Belli et al, 1997 ; Mathias, Costa, et al, 2010 ; Mathias et al, 2011 ; Taraboanta et al, 2019 ; Vohra et al, 2020 ). Data from four studies were pooled (Mathias, Costa, et al, 2010 ; Mathias et al, 2011 ; Taraboanta et al, 2019 ; Vohra et al, 2020 ) two of which (Mathias, Costa, et al, 2010 ; Taraboanta et al, 2019 ) had subgroups of resin composite materials, into a dataset and found evidence that cigarette smoke causes increased staining of resin composite materials when compared to a non‐smoker exposure control of (MD: 11.90; 95% CI: 11.47, 12.34; I 2 : 100%). The study not included in the meta‐analysis, Belli et al ( 1997 ), also showed evidence of an increase in staining in two resin composites tested upon exposure to cigarette smoke versus a distilled water control (Supporting Information: Table 5 ).…”

“…Eight studies compared the staining effects on different types of resin composite (Alandia‐Roman et al, 2013 ; Belli et al, 1997 ; Malhotra et al, 2011 ; Mathias, Costa, et al, 2010 ; Mathias, Silva, et al, 2010 ; Taraboanta et al, 2019 ; Theobaldo et al, 2020 ; Wasilewski Mde et al, 2010 ). The data from these studies could not be pooled due to the variation of resin composite products used and differences in methods.…”

“…Two studies assessed the effect of sealants on teeth and how these may change tooth color upon cigarette smoke exposure (Mathias, Silva, et al, 2010 ; Taraboanta et al, 2019 ) (Supporting Information: Table 5 ). Taraboanta et al ( 2019 ) assessed the effect of three treatments used to manage white spot lesions on enamel (ICON resin infiltration, Recaldent MI Varnish, and Grandio Seal nanohybrid resin composite). They found evidence that all three products led to staining of the teeth after exposure to cigarette smoke, with ICON showing the most change.…”
