Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser
Advanced Materials Interfaces, EarlyView.The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.
