Estudo das altera es em esmalte de dentes decíduos após exposi o a bebidas disponíveis no mercado

The purpose of this study was to evaluate the morphology and surface texture of temporary teeth enamel before and after exposure to fi ve different solutions, including industrialized drinks, available in the national market and routinely consumed by children (artifi cial saliva, Coca-Cola, Kapo juice (strawberry fl avor), Del Valle Monsters juice (peach fl avor) and Yakult). The pH of these drinks was measured and fi fty human deciduous canines were randomly distributed into five groups. The vestibular face of each tooth was delimited in its long axis, and part of it was immersed in 50 mL of solution for 15 minutes and rinsed with deionized water for 15 seconds. Both faces were analyzed through perfi lometer (FormTracer model SV-CS25). The statistical analysis showed no differences between the faces (control and treated) and beverages evaluated. The morphological analysis by Scanning Electron Microscopy showed different dental structure loss patterns, suggesting greater morphological change in more acid beverages. So, it was concluded that the solutions demonstrated erosive potential, but there were no statistical differences between the faces (control and treated) of human deciduous canines and the effects caused by drinks on the dental enamel surface.
