Abstract
The present invention provides a method of evaluating the risk of possible caries and the device, system, and program of the same, which is useful for the subjects to keep their mouth conditions best by measuring the chemical properties of saliva samples collected from the mouths of subjects to allow for easy and sanitary evaluation of the risk of possible caries in a short time and to help the subjects accurately recognize their risk of possible caries and closely consult their dentist. In the present invention, saliva from the mouth of subject is collected, a given ratio of acid is added to the saliva, and the chemical property of the saliva is measured to evaluate the risk of possible caries base on the measured value.

2. A method of evaluating the risk of caries having such a characteristic that the saliva is collected from the mouth of the subject, the chemical property of the saliva is measured using a chemical property measuring device, a given ratio of acid is added to the saliva, and the chemical property of saliva is measured again to evaluate the risk of possible caries based on the difference between the measured value of chemical property of saliva before adding acid and that after adding acid.
- 4. A device of evaluating the risk of caries having such a characteristic that it is composed of a container for storing the saliva collected from the mouth of the subject, a sensor surface, which comes to contact with the saliva to measure the chemical property of the saliva, and a computing part for evaluating the risk of possible caries based on the measured value for the chemical property of the stored saliva after a given ratio of acid is dropped in the saliva in the container.

5. A device of evaluating the risk of caries having such a characteristic that it is composed of a container for storing the saliva collected from the mouth of the subject, a sensor surface, which comes in contact with the saliva to measure the chemical property of the saliva, and a computing part for evaluating the risk of possible caries based on the difference between the measured value for the chemical property of the stored saliva immediately after the collection and that after a given ratio of acid is dropped in.
- 7. A system of evaluating the risk of caries having such a characteristic that it is composed of a measuring device for measuring the chemical property of the saliva collected from the mouth of the subject, a server having a database storing evaluation criterion data used in evaluating the risk of possible caries based on the measured value for the chemical property of the saliva to possess a risk evaluation function for evaluating the risk of possible caries for the subject using the measured value for the chemical property measured by the measuring device, a terminal having at least an evaluation output function for outputting the result of the evaluation of the risk of the possible caries, and a network for performing at least one of data inputs/outputs among the measuring device, the server, and the terminal.
- 21. A program of evaluating the risk of caries having such a characteristic that it involves a step for obtaining the measured value for the chemical property of the saliva collected form the mouth of the subject, a step for referring to the evaluation criterion data in evaluating the risk of possible caries based on the measured valued for the chemical property contained in the database, and a step for outputting the obtained measured value for the chemical property in the form of the grade of evaluation of the risk of possible caries based on the evaluation criterion data, and that these steps are performed by a computer.

23. A method of evaluating the risk of caries having such a characteristic that it measures the chemical property of the saliva collected from the mouth of the subject and outputs the measured value for chemical property in the form of the grade of evaluation of the risk of possible caries of the subject by referring to the database recording the evaluation criterion data for evaluating the risk of possible caries in accordance with the measured value, creates an electronic medical chart recording the dental condition transition data containing the measured value for the chemical property of the subject'"'"'s saliva, and performs at least one of input of the measured value for the chemical property, reference to the database, and output of the grade of evaluation of the risk of possible caries through data communications via a network.
