Purpose: This study evaluated the influence of different storage times and storage solutions on the mineral content of enamel. Methods: Ninety enamel slabs were randomly divided into 2 groups of 45: a 45-day group and a 90-day group. Each of these main groups was further subdivided into 9 experimental groups of 5 slabs, and each subgroup was stored in a different storage solution. The mean percentage weights of 5 elements (calcium, potassium, sodium, phosphorus, and magnesium) presented in each enamel slab was measured after storage using inductively coupled plasmaatomic emission spectrometry. Two-way analysis of variance (ANOVA) and Turkey’s honestly significant difference tests were used to analyze differences between the groups. Results: Storage conditions significantly affected the levels of calcium, potassium, sodium, and phosphorus (p < 0.05). Storage procedures can significantly affect the calcium, potassium, sodium, and phosphorus contents of enamel.
