Abstract

Introduction: Demineralization denotes the dissolution of the calcium and phosphate ions from the hydroxyl-apatite/tooth structure into the plaque and saliva caused by the acidic attack. White spot lesions start at the outermost layer of the teeth, damaging the dental hard tissues through the loss of mineral ions from the hydroxyapatite lattice at the surface. An ideal remineralizing agent should mimic the organization and micro-architecture of natural tooth structure mineral crystals to the greatest extent possible. Aim: Study aimed to evaluate and compare the effect of two remineralizing agents on remineralization of initial enamel carious lesions. Furthermore, the impact of both remineralizing agents and one infiltrating resin material on the color of demineralized enamel and their ability to mask white spot lesions was investigated.
Subjects and Methods: 50intact, freshly extracted permanent human anterior central incisors (extracted from diabetic patients) were selected and stored in distilled water at room temperature (220C). Selected teeth were classified into two main groups (Control and Demineralized) according to the type of treatment. Results: Significant differences resulted between treatments for ΔE at p < 0.001. Demineralized enamel showed the highest significant color change values (6.03±0.4). All treatments of demineralized enamel significantly restored the tooth color. In contrast, ICON revealed the highest color difference values (4.13±0.19) of all three treatments, followed by MI Paste Plus (3.06±0.22), then Curodont Repair (2.18±0.19), which showed the lowest change in color (ΔE). Conclusion: Curodont Repair and MI Paste Plus can fill up defects and micropores on demineralized tooth structure, significantly restoring the tooth color.
