The early detection and diagnosis of the carious lesion are a primary consideration of the minimal intervention dentistry (MID) concept. Detection is the identification of a demineralized lesion, while diagnosis is an iterative process using further information from the patient to identify the lesion as carious in nature. Traditionally, visual, tac...
