Abstract

This study aimed to analyze and compare the effects of toothpastes containing theobromine and hydroxyapatite on enamel microhardness after immersion in a carbonated drink. The remineralizing abilities of both toothpastes were also evaluated and compared. The crowns of 21 maxillary first premolars were immersed in a carbonated drink for 10 min. The specimens were divided into three groups as follows: those brushed with toothpastes containing theobromine (n = 7) and hydroxyapatite (n = 7), and those brushed with aquadest (n = 7) for 9 min and 20 s each. The enamel hardness was measured after each treatment. A significant decrease in enamel hardness (average, 114 ± 12 KHN) was noted in all specimens after immersion in the carbonated drink. Kruskal-Wallis and Mann-Whitney tests revealed significant changes in hardness values after brushing with the theobromine- and hydroxyapatite-containing toothpastes. Enamel microhardness values were increased by 42 ± 9 KHN in the theobromine group and 55 ± 6 KHN in the hydroxyapatite group. Furthermore, enamel hardness in the theobromine group was significantly higher than that in the hydroxyapatite group (p < 0.05).
