Methods Based on Sound Waves

Ultrasound Devices

Ultrasound technology is being explored for caries detection by measuring the reflection of sound waves from different layers of the tooth structure. This approach has potential for detecting deep caries and monitoring lesion progression. However, a limitation of this technique is that it can only identify dental caries once the tooth has undergone a certain level of damage, after structural changes in the enamel and dentin have already occurred.⁵³
