Research Abstract

Ultrasonic measurement system for mineral density of tooth surfaces had been developed. This system actualized significantly sensitive, non-destructive, and quick measurement. Using this system, we analyzed the relationship between mineral density of tooth and oral environment, especially function of saliva. The result revealed that acid resistivity was correlated with ultrasonic density of tooth mineral. This indicated the possibility of developing new preventive program against tooth decay according to the ultrasonic density of tooth mineral, buffering capacity of saliva, and living practice of daily life.
