“…This newly formed surface was tought to mask the subsurface stain and this is called "the abrosion effect 28 . Depending on the fact that acid etching procedure aims to remove the surface layer of incipient caries lesions which has a varying thickness of 40 µm and mineral content of up to 82 vol%, 19 it is possibly acceptable to apply acid etching to remove microabraded superficial enamel The positive effect in masking the white spot lesions by resin infiltration technique has been showed in many in vitro/in vivo studies 17,29 . White spot lesions show an apparently intact surface which is followed by a more porous lesion body underneath and the increased porosity within the lesion body causes the whitish appearence of these lesions 29 .…”

“…Indeed, light scattering at interfaces between substances of lesion body with different refractive indices (RI), like enamel/apatite (RI 1.62-1.65), water (1.33) or air (1.00), is responsible for the chalky white appearence of enamel lesions. [30] When the watery medium or air in microporosities of lesions replaced by a resin infiltrant with a refractive index closer to apatite crystals (RI of infiltrant: 1.52), light scattering reduces, thus the esthetic appearence of opaque white lesions can be improved due to the blending effect 17 . In this case after microabrasion and bleaching, however the stains were removed, a whiter appearence was obtained and the resultant colour was satisfying for the patient, the remained whitish and brownish coloured patchy areas were still needed to be improved.…”

“…The resin penetrates into the lesion body driven by capillary forces, so that it occludes the microporosities in the lesion body 16 . As a side effect, the resin infiltrant can also mask the chalky white appearance of the lesions and this 'side effect' will improve the esthetic appearence of mild to moderate fluorosis cases in a minimally invasive manner 17 .…”

In todays' modern dentistry, the undesirable appearence of dental fluorosis need to be improved to satisfy patients' esthetic requirements in a minimally invasive manner. The approach proposed for the treatment should remove the stained enamel defects, provide blending effect for chalky white appearence and strengthen the enamel against caries development. The purpose of this case report is to present the clinical results of a combined esthetic treatment of a severe fluorosis case with microabrasion, bleaching and resin infiltration. Treatment plan was based on a combined approach of microabrasion, home bleaching and resin infiltration. An improvement in the esthetic appearence was achieved and remained stable in the 6-months follow-up. The technique might be more minimally invasive, less time consuming and cheaper compared to restorative techniques.

“…First of all, in order to protect soft tissues from any damage of the microabrasion paste, a light-cured resin barrier (OpalDam Green, Ultradent Products Inc, [12][13][14][15][16][17] UT, USA) and a lip&cheek retractor (OptraGate, Ivoclar Vivadent Inc, NY, USA) were applied. Both patient and clinician wore protective glasses for protection of their eyes.…”

This study evaluates color change of the enamel lesion before and after resin infiltration and after thermocycling (TC) in order to assess clinical usefulness of resin infiltrant in restoring esthetics of incipient enamel caries lesions. Twenty‐five healthy premolars were prepared and crown portions were vertically cut. Specimens were emerged in acryl blocks with relatively flat proximal surface facing outside. Specimens were put in decalcification solution (50 mM acetic acid solution, 3 mM CaCl2·H2O, 3 mM KH2PO4, 6 µM methylhydroxydiphosphonate, pH 4.95, 37°C), and were kept for 160 h, in order to make white spot lesions on the exposed enamel. Degree of decalcification was observed with microscope and nine specimens were excluded because of inadequate decalcification (n = 41). L*, a*, and b* were measured with colorimeter at the baseline (T1), after production of white spot lesions (T2), after infiltration of resin infiltrants (ICON®, DMG, Hamburg, Germany) (T3), after 3000 (T4), 6000 (T5), and 10,000 cycles (T6) of TC. L* was highest at T2, but significantly decreased until T6 which was the closest value to T1 (P < 0.05). a* was highest at T2 and decreased gradually until T6, whereas b* was lowest at T2 and was highest at T3 and decreased gradually until T6. Δ Eab * less than 3.7 showed between T1 and T4, between T1 and T5, and between T1 and T6, which suggested that it was hard to differentiate one from the other clinically. Resin infiltrated lesions showed recovery of CIE value close to that of healthy enamel over time. © 2013 Wiley Periodicals, Inc. Col Res Appl, 39, 506–510, 2014
