White spot lesions (WSLs) are defined as enamel surface and subsurface demineralisation without cavitation. These manifestations represent the first clinical observation of the progression of dental caries with the possibility being reversed. These lesions are characterised by a white chalky, opaque appearance. It is possible to see WSLs in patients after fixed orthodontic treatment that make oral health difficult and increase risk of enamel demineralisation.1

The specific aspect of these lesions is due to an optical phenomenon, as demineralisation process causes an increase in the pore volume and the refractive index (RI) of the enamel changes because of air and water presence. There are predisposing risk factors such as poor oral hygiene, altered salivary flow and the presence or absence of fluoridation areas. I...
