Treatment of Enamel Opacities according to a newly suggested Classification: An Experimental Study
Objectives: clinically assess the role of the new classification of enamel white lesions in insuring a more predictable treatment
Methods: A newly suggested classification of enamel opacities, based on direct clinical observation and transillumination, was used to classify enamel opacities topographically into three categories: deep, mixed, or superficial lesions. 12 patients with white opacities on their incisors were treated according to their topography. Apart from the superficial lesion which was infiltrated right after surface erosion using 15% hydrochloric acid, deep and mixed lesions were eventually treated with a combined use of microabrasion followed by infiltration of the lesion to correct the esthetic defect.
Results: Topographically deep lesions showing a creamy discoloration clinically with ill-demarcated margins in transillumination; revealed clearly neat chalky appearance in direct clinical observation and well-defined borders under transillumination after removing the superficial sound enamel covering the deep hypomineralization using micro-abrasion. The infiltration of that followed using a low viscosity resin was successfully obtained as in superficial lesions; with a satisfying esthetic improvement
Conclusions: This clinical experimental study highlights the major role of the new classification of enamel opacities in aiding a more predictable treatment outcome thanks to the use of direct visual inspection and light-based observation under transillumination. This new classification has allowed a fast, easy and a more predictable and conservative treatment.
Thus, this classification has a marked prognostic effect even in cases where the etiology was ill- or not even defined and based only on the topography of the lesions.
