Abstract

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.

Description

technical field

[0001] The present invention relates to methods for assessing caries, remineralization, demineralization and erosion in occlusal surfaces of teeth, such as pits and grooves. The methods described herein are particularly useful for determining the anti-caries efficacy of oral care compositions, such as solid chewable unit dosage forms. Background technique

[0002] Oral care products such as toothpaste are used daily by consumers as part of their oral care hygiene regimen. These oral care products treat a variety of oral conditions, including the treatment and prevention of caries, demineralization, erosion, and plaque. These products include, for example, fluoride-containing dentifrices for consumer use, concentrated fluoride solutions or gels, etc., which are typically applied at regular but infrequent intervals in a dental office, and the like. Despite the availability of these treatments, the occurrence of dental caries and demineralization remains a pro...
