The aim was to synthesize a toothpaste and analyze its effect on surface micro-hardness and roughness of enamel. Basic paste was prepared by using basic ingredients. Theobromine (0.2 wt%) and laboratory synthesized fluoridated-bioactive glass (F-BG, 4 wt%) were added to it. Post-demineralization, 36 enamel blocks were divided into six groups that were brushed with their respective toothpaste+artificial saliva (AS): group 1 (control): basic paste; group 2: basic paste+theobromine; group 3: commercial theobromine toothpaste; group 4: commercial BG toothpaste; group 5: basic paste+F-BG; and group 6: basic paste+theobromine+F-BG. On micro-hardness analysis, group 6 performed best, followed by group 4. Surface roughness results showed the maximum decrease in roughness values for group 6, followed by group 5. Treatment with toothpaste composition containing theobromine+F-BG resulted in the enamel's increased micro-hardness and decreased surface roughness.
目的是合成一种牙膏，并分析其对牙釉质表面显微硬度和粗糙度的影响。基本牙膏由基本成分制成。向其中添加可可碱（0.2wt%）和实验室合成的含氟生物活性玻璃（F-BG，4wt%）。脱矿化后，将 36 个牙釉质块分为六组，用各自的牙膏加人工唾液（AS）刷牙：第 1 组（对照）：基本牙膏；第 2 组：基本牙膏+可可碱；第 3 组：市售可可碱牙膏；第 4 组：市售 BG 牙膏；第 5 组：基本牙膏+F-BG；第 6 组：基本牙膏+可可碱+F-BG。在显微硬度分析中，第 6 组表现最好，其次是第 4 组。表面粗糙度结果表明，第 6 组的粗糙度值降低最大，其次是第 5 组。使用含有可可碱+F-BG 的牙膏处理可使牙釉质的显微硬度增加，表面粗糙度降低。
