| 摘要 |
This invention relates to methods for evaluating caries, remineralization, demineralization, and/or erosion in occlusal surfaces of the teeth such as the pits and fissures. Specifically, the present invention relates to an intra oral method of evaluating caries on occlusal surfaces, comprising: a. preparing a dental specimen having at least one closed ended trough; b. preparing a temporary crown or artificial tooth having a well on the occlusal surface; c. placing the dental specimen into the well wherein the trough opening of the dental specimen is facing outward; d. seating the temporary crown or artificial tooth in the oral cavity of the test subject; e. exposing the oral cavity of the test subject to test conditions; f. measuring the degree of caries efficacy on the dental specimen. The methods described herein are especially useful for determining the anticaries efficacy for oral care compositions such as solid, chewable unit dosage forms. |
