Comparative Study Using Scanning Electron Microscopy and Energy Dispersive X-Ray Spectroscopy to Assess Morphological Modifications to the Enamel Surface Produced by Three Sodium Fluoride Solutions

Cristina S. Nicolae, Corneliu I. Amariei

Aims: The first aim of this in vitro study was the comparative assessment of enamel surface morphology and analytical assessment of calcium and fluoride ions after topical application of three sodium fluoride solutions: solutions A and B having the same concentration (0.05% sodium fluoride) and solution C having a higher concentration (0.1% sodium fluoride). The second aim was to assess the remineralisation capability of solution A, which has not previously been studied. Methods: Twelve sound premolars, extracted for orthodontic purposes from patients aged between 12-15 years, were used. Demineralisation areas were created by etching with 37% phosphoric acid gel for 60 seconds. Enamel sections were immersed in 100 ml of three solutions, twice daily for 30 days: solution A
