A method of diagnosing optical inhomogeneity of a volume scattering object is provided. The method includes the steps of providing a substance coated with phosphorous materials, adapting the substrate to a surface of a volume scattering object to be diagnosed, and trans-illuminating the volume scattering object with radiation. A dental tool including a substrate is also provided. The substrate includes a transparent flexible film or metallic foil with an applied coating of upconversion phosphors, afterglow particles or both.

A three-dimensional printing system including a feed source of uncured filled resin material, a print head configured to apply discrete layers of a composition including upconversion phosphors, and a radiation source configured to irradiate layers of uncured filled resin material and deposited layers of the composition is provided. A method of three dimensionally printing a dental article is also provided.

Provided herein are compositions for applying a reference marker pattern or grid to the surface of an object to be imaged three-dimensionally. These compositions can be quick drying for ease of use. Methods of use of the compositions are also provided as well as devices and kits for the application of the compositions.

A fit checking material composition for dental use includes a first paste and a second paste. A mixture of the first paste and the second paste 35 seconds after mixing the first paste and the second paste, has a consistency of 37 mm or greater and 43 mm or less at 23 C.

The disclosure is directed to compositions and methods related to colorimetric detection for dental uses (e.g., detecting the presence or absence of a dental caries, and/or cavity or cavities, or precursor thereof), including a rapid unambiguous color indicator that allows for visualization by an unassisted eye based on a localized oral pH reading.

The present disclosure relates to a plaque disclosing composition containing riboflavin 5-phosphate sodium, a method for disclosing a plaque, wherein the plaque is an acquired pellicle, and a method for collecting and analyzing an information about the amount and characteristics of dental plaque by analyzing the color and intensity of fluorescence emitted by riboflavin 5-phosphate sodium for effective treatment of dental plaque even at an early stage.
