Enamel microabrasion was developed in the mid-1980s as a method of eliminating enamel discolouration defects and improving the aesthetics of the teeth. Several years after the method was developed, much has been learned about this technique, long-term results of treatment, and microscopic changes to the enamel surface that have distinguishable clinical implications. This case report describes a technique used to treat smooth surface white spot lesions micro invasively by a chemo-mechanical method using the latest treatment protocol of microabrasion.
