Comparison of Two Resin Infiltrants Used for Masking Enamel White Lesions.
Objectives:
The resin infiltration technique has shown to treat and mask the enamel white lesions (EWLs) by modifying their refractive index.To date, the only infiltrant available is Icon (DMG, Hamburg), however by modifying the infiltration procedure, an other resin may be used as an infiltrant to improve the aesthetic appearance of these lesions.The aim of this clinical study was to compare the Icon Infiltrant with the PermaSeal Resin (Ultradent, Jordan) on masking and aesthetic improvement of the EWLs.
Methods: Two groups (n=14) presenting EWLs were selected. In each group (n=7), we performed 10 cycles of micro abrasion during 10 seconds using Opalustre® (Ultradent, Jordan), 30 seconds of etching using Ultra-Etch (Ultradent, Jordan), 5 min of deproteinization by sodium hypochlorite, and finally we dried the lesion using ethanol during 30 seconds.
In the first group we performed the infiltration using Icon as recommended by the manufacturer. For the second group, PermaSeal was used until the lesion is masked.
Standardized photographs were taken and L*a*b colour values were measured (photoshop CS4) in infiltrated enamel areas and on sound enamel.
Results: The comparaison of the colour differences (DeltaE) between preoperative and postoperative photographs showed a notable to high significant (NBS criteria) masking for both groups, Statistical Analysis of the colour improvement showed that there is no significant differences between both infiltrants in masking EWLs (p>0,05).
Conclusions: PermaSeal can be used as well as Icon to aesthetically improve the enamel appearance of the white lesion. However further investigations should be made to improve the infiltration procedure.
