Abstract:The aim of this in vitro study was to analyze the effect of green tea on the hardness of eroded dentin. MATERIALS AND METHODS 40 extracted sound human premolars with premeasured hardness values were immersed in Coke for five minutes and then immersed in a green tea solution for five minutes. The surface hardness was remeasured with a Vickers diamond under a load of 500g/10s immediately after each immersion. All hardness values were compared with pretreatment values by the Wilcoxon test. RESULTS The mean ± SD o… Show more
