Concealment effect of resin infiltration on incisor of Grade I molar incisor hypomineralization patients: An in vivo study

Abstract

Context:Molar incisor hypomineralization (MIH) is a commonly occurring esthetic setback among patients. Depending on the graveness of the lesion, esthetics of MIH can be improved by treatments such as enamel microabrasion, bleaching, composite resin bonding, and the combination of some or all of these techniques.Aim:The aim of this study is to evaluate the esthetic results of resin infiltration treatment on incisors with Grade I molar incisor MIH.Materials and Methods:A total of 22incisor lesions with MIH were infiltrated with resin. Photographs were captured before infiltration, just after infiltration, and 6 months after infiltration. The photographic evaluation was done by the CIE L*a*b* scoring method. The means of each parameter such as ΔL and ΔE were calculated.Statistical Analysis:ANOVA in conjunction with Turkey's post hoc test was used to evaluate the means.Results:The total color change observed was equal just after treatment and 6 months after treatment, with no statistically significant difference (P = 0.87) between these two time points. The mean of difference in total color change (ΔE3) of white tooth discoloration was 13.2 SD 6.8, showing an overall color change.Conclusion:Infiltration can conceal the white opaque appearance of Grade I MIH lesions, and also reduction in lesion whiteness is seen with time.

Erosion Infiltration in the Management of Molar-Incisor Hypomineralization (MIH) Defects

“…Case Reports in Dentistry Once infiltrated, white spot lesions take on the appearance of the surrounding healthy enamel [11,15,16]. In this case report, the resin infiltration technique was applied to the maxillary central and lateral incisors giving an aesthetically satisfactory result, in accordance with the finding of previous studies [8].…”

“…The characteristic feature of MIH is the clear demarcation between the affected and sound enamels [9]. The incisor defects are usually without loss of enamel substance and are generally less serious than those seen in molars due to the absence of chewing forces [11]. The risk of defects to the upper incisors appears to increase with an increasing number of affected FPMs.…”

“…Apart from keeping the environment moisture-free, additional steps must be taken to dry the lesion. This is accomplished by treating the lesion area with alcohol, which evaporates the water within the porosities that could inhibit the process of infiltration [11,13,14].…”

Comparative evaluation of surface roughness and color stability of nanohybrid composite resin after periodic exposure to tea, coffee, and Coca-cola ” An in vitro profilometric and image analysis study

“…CIE LAB was developed by the Commission Internationale de I'Eclairge in 1931. A color difference (ΔE) between two objects can be calculated as the Euclidean distance between two coordinates (before and after) in the color space according to the following equation:[ 16 ]…”

Resin infiltrants- A new era in minimal intervention dentistry

“…The infiltration of the resin owing to its low viscosity into the voids of enamel has been shown in many in vitro studies. Eckstein et al 29 in their study showed that infiltrant material's concealment effect on WSL had no statistically significant or clinically relevant additional color or lightness alterations between 6 and 12 months after infiltration.In the study by Bhandari et al 30 a 6-month follow-up was done and a reduction in the whiteness of white spot and also change in total color were noted only after treatment and 6 months after treatment, following resin infiltration. This study shows that resin infiltration shows immediate results and also it shows further improvement overtime.Similar results were observed by Cohen-Carneiro et al 31 who showed that lesions infiltrated with icon had good colour matching.…”
