Abstract: A method for facilitating caries detection is to be performed based on a grayscale image of teeth, and includes: obtaining an object detection model; obtaining a detection image using the object detection model based on the grayscale image, wherein the detection image is the grayscale image labeled with a plurality of tooth crown marks and a caries mark; and for one of the tooth crown marks that has the caries mark provided thereon, determining a width and a height of the tooth crown mark and a width and a height of the caries mark, and calculating a caries ratio based on the aforementioned widths and heights to obtain an evaluation result that indicates a severity of caries.

Abstract: The present invention provides a producing method for a tiny bone defect repairing material. The invention solves the problems that the setting time is too long to cause bad mechanical property in conventional bone cements and also remains bioactivities and water absorb ability. The invention has no cytotoxicity and enables to stimulate cells growth.
