Light-Based scanner spots early tooth erosion before It's visible

This study tests whether a non-invasive imaging tool called swept-source optical coherence tomography (SS-OCT) can detect early signs of tooth erosion caused by acidic drinks. Twenty-two healthy adults swished orange juice repeatedly over three days, and their teeth were scanned with SS-OCT to measure changes in enamel. The study also looked at whether chewing sugar-free gum after the acid exposure could help protect the teeth. The goal is to see if this technology could be used in dental clinics to catch erosion early and guide prevention.
