Aim:
To analyze the comparative change in pretreatment and posttreatment La*b* values of color in initial nonpitted white spot lesions of fluorosed teeth after resin infiltration with DMG-Icon spectrophotometrically with VITA easy shade.
Materials And Methods:
A total of 30 maxillary and mandibular permanent anterior teeth with mild, nonpitted white spot lesions (atleast one) of fluorosis [till grade IV of Thylstrup and Fejerskov (TF) index] in patients between 6 years and 14 years of age were included in the present study. Shade of selected tooth and its white spot lesion area was recorded using VITA 3D shade guide, both pre and postoperatively, i.e., after application of DMG Icon. This was followed by recording the change in corresponding La*b* values of tooth shade and white spot lesion spectrophotometrically using VITA Easy Shade. Results obtained were analyzed statistically.
Results:
ΔE value of color change was found to be less than 3.7 in most of samples after resin infiltration and esthetically color change to naked eye was statistically significant (p value < 0.00001) postoperatively.
Conclusion:
Resin infiltration with DMG Icon can improve the color of non-cavitated white spot lesions. The esthetic effect of this treatment was evident immediately after treatment. Moreover, no cavitation occurred after etching, even when the surface layer had been eroded completely.
Clinical Significance:
Achievement of esthetic results without loss of tooth structure and postoperative sensitivity.
