Abstract :

An invitro study was conducted to assess the efficacy of Tricalcium phosphate(β– TCP) and Casein phosphopeptide –amorphous calcium phosphate(CPP–ACPF)to prevent tea stain absorption on the enamels of thirty freshly bleached teeth .The specimens were bleached using 10% Carbamide Peroxide and divided into three groups 1,2 and 3, receiving no surface treatment, β– TCP and CPP–ACPF respectively. All specimens were then exposed to tea solution and the colour change in all the groups were analysed using digital photography software(Adobe CS5 ). The results indicated that both β– TCP and CPP–ACPF were effective(p<0.05) in preventing stain reabsorption after exposure to tea solution with β– TCPbeing superior(Group 2) to Group 1 (Control) and Group 3(CPP–ACPF).
