AI Technical Summary
Existing treatments for microcracks in teeth can easily damage the enamel and dentin, and may cause dentin hypersensitivity due to chemicals, and cannot effectively repair microcracks.
Low-energy ultrafast lasers are used to focus on the microcrack areas on the tooth surface. By adjusting the laser power, exposure time, and scanning speed, the enamel is rapidly melted and flows to fill the cracks. Multiple laser exposures and scans are performed to reduce thermal stress. Finally, laser polishing is performed to remove surface defects.
It achieves high-precision repair of hidden tooth cracks without the need for foreign materials, avoiding tooth damage and bacterial erosion. The repaired area is smooth with no obvious defects, preventing further deterioration.
