Technique Tips

Discoloration of enamel commonly occurs due to developmental defects, fluorosis and post-orthodontic treatment. Enamel discoloration can be an increasing aesthetic concern for patients. Conventional treatments include tailored oral hygiene, fluoride application and remineralizing agents in the first instance. Following this, more invasive options may be considered, including microabrasion and conventional direct and indirect restorations. The technique described shows the use of a resin infiltration system to improve aesthetics of white spot lesions to mask the appearance, prevent lesion progression and delay the restorative cycle.

Discolorations and white lesions in anterior teeth present as a management challenge, particularly in the younger patient. The use of destructive techniques creates a lifelong treatment burden and initiates the restorative cycle. Vital bleaching has been used with great success for the brown lesions seen in molar incisor hypomineralization (MIH) and fluorosis. The white lesions associated with these conditions and orthodontic decalcification, have historically required more invasive treatment. With the introduction of smooth surface resin infiltration systems, there is now a minimally invasive and pain-free approach that is a successful adjunct to the management of these lesions. Currently, only Icon (DMG, Hamburg, Germany) is on the market in the UK.
