Bleach, infiltrate and restore
The Infiltration technique has been widely proven to eliminate unaesthetic enamel spots, if the depth is correctly evaluated and the indications followed correctly; in other words, in deep lesions infiltration will not be very effective alone.
Moreover, bleaching is not a vanity procedure anymore: for many years now, the benefit of non-invasive techniques has been put on trial and getting amazing results when the indications are followed correctly. The bleaching therapy to diminish and treat white spots has been subject to controversy, rejected by many and adopted by many others.
In the Author’s experience, bleaching of white and amber spots before treatment is a winning strategy with the following statements:
• Amber spots: Generally turn into white spots which are more subject to the acid treatment of the infiltration therapy
• White Spots: Two phenomena happen, the first is the reduction in their opacity due to a balance in the refraction index of the disarranged prisms. And the second, little or no bleaching happen to the white spot, blending better due to the low contrast between the newly bleached surrounding tissues and the white spot itself.
Bleaching should be a mandatory resource before stain treatment and restorative therapy. Some of the benefits are little known by the dental professionals and harmless side effects are often feared. Infiltration therapy should be a primary choice together with bleaching for the treatment of these kind of problems.
ICON dry, which is used as a preview of the resin filtration after erosion, should be applied for 2 minutes to obtain proper visual assessment. ICON infiltration resin has to penetrate completely and a 3 minute application is advised.
