Abstract
This study aimed to investigate the free calcium released from different brands of toothpaste after incorporation with a beta-tricalcium phosphate (β-TCP)/amorphous calcium phosphate (ACP) mixed powder and with β-TCP powder alone. Four brands of toothpaste were used for the experiment: Nano-Bio Activation Toothpaste, Colgate Total Advanced Whitening Toothpaste, BORONIA Herbal Whitening, and BioMin F. The investigated β-TCP and ACP powders were prepared by a two-step sintering method using raw coral material. Analytical results found that the mean calcium concentration of the β-TCP/ACP (2:1) powder in deionized water was 3.4% when the pH was between 5 and 9. Moreover, statistical results revealed that the toothpaste containing β-TCP powder had significantly higher calcium concentrations than the normal toothpaste. The toothpaste containing mixed β-TCP/ACP powder had a higher calcium concentration than the toothpaste containing only β-TCP powder. Twice as much free calcium could be released from β-TCP/ACP toothpaste than from β-TCP-only toothpaste. Thus, toothpaste containing β-TCP/ACP mixed powder offers greater benefits to facilitate the remineralization of enamel than toothpaste containing only β-TCP.
