Linear enamel hypoplasia explained

Linear enamel hypoplasia (LEH) is a failure of the tooth enamel to develop correctly during growth, leaving bands of reduced enamel on a tooth surface.^{[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]} It is the most common type of enamel hypoplasia reported in clinical and archaeological samples, with other types including plane-form enamel hypoplasia and pitting enamel hypoplasia.^[12]

Linear enamel hypoplasia can be caused by a variety of factors, from genetic conditions to malnutrition and illnesses during childhood.
