Spectrophotometric evaluation of white spot lesion treatment using novel resin infiltration material (ICON^®)

Abstract

Aims and Objectives:The aim of this study is to compare the esthetic improvement of white spot lesions (WSLs) treated by icon, sodium fluoride (NaF), and bioactive glass using VITA Easyshade® spectrophotometer.Methodology:Ninety intact human maxillary central incisors were collected and artificial WSLs were created on facial surface having dimensions of 4 mm × 4 mm by immersing in demineralized solution for 4 days, baseline comparisons were performed by measuring the color of the WSLs compared to the adjacent sound enamel. All samples were divided into three groups of 30 each. Three groups were Group 1: Treated by NaF, Group 2: Treated by the bioactive glass, and Group 3: ICON®-DMG America (Resin infiltration). After treatment, the specimens of all groups were stored in artificial saliva and reevaluated at 4 and 8 weeks after the beginning of the treatments with VITA Easyshade® spectrophotometer.Results:Statistical analysis was performed with One-way analysis of variance. Post hoc analysis with the Tukey's honest significant difference test was used to compare the data between the groups. Among three groups, resin infiltration has significant color change (ΔE) of infiltrated lesions when compared to other treatment groups (P < 0.001)Conclusion:Within the limitations of this study, it can be concluded resin infiltration (ICON®) can improve the esthetic characteristics of WSLs. Resin (ICON®) is a better treatment option when compared to bioactive glass and NaF as concerned to esthetics.

Study of Cytotoxic Properties of an Experimental Preparation with Features of a Dental Infiltrant

“…Aesthetics is an important aspect of modern dentistry, and infiltration allows for minimally interventional treatment of lesions while maintaining the continuity of the patient’s own tissues, which definitely has a positive effect on the final result in terms of aesthetics of the treated area. Studies available in the literature have shown that not only Icon infiltrant, but also the composite sealers Opiguard (Kerr, Orange, CA, USA) and PermaSeal (Ultradent, South Jordan, UT, USA) applied on the surface of early carious lesions proved to be able to infiltrate and, moreover, showed similar improvements in terms of aesthetics, and the colour stability of the infiltrated white spots lasted for at least 2 months [ 26 , 27 ]. That issue was also addressed by Paris et al and Yuan et al, who found that colour change and masking of early carious lesions can be achieved with use of infiltrants whose RI (refractive index) is close to that of enamel [ 28 , 29 ].…”

Mineral Content Identification of White Spot Lesions Around Orthodontic Brackets Following the Use of Different Concentrations of Nano-Hydroxyapatite Mouthwash And Fluoride Gel

“…One major goal of preventive dentistry is to stop the progression of incipient carious lesions and induce their remineralization. This is done to prevent the extension of carious lesions and preserve the tooth structure (19).…”

“…The cariogenic solution had a pH of 4 and contained 0.5 g yeast extract, 1 g glucose, and 2 g sucrose. Several studies show that such a procedure using artificial cariogenic solutions can simulate WSLs as they form in the oral environment (19,20). The formed biofilm was wiped off by a wet gauze and the nail varnish was removed with a scalpel.…”

Methylene Blue Penetration of Resin Infiltration and Resin Sealant in Artificial White-Spot Lesions

“…Resin infiltration stopped enamel demineralization and corrected the appearance of white-spot lesions. [11][12][13] This procedure seems to be microinvasive; therefore, it could act as a bridge between noninvasive and minimally invasive procedures for treating initial carious lesions. 14 The goal of this approach is to use resin monomer to infill the intercrystalline micropores inside the lesion body.…”
