I assumed the drilling was to simulate tooth decay and to remove something to be grown back as a trial, did I read it incorrectly?

- PhantomGremlin 10y agodid I read it incorrectly? The way I interpreted it, they drilled into teeth from the top in order to reach the "adult dental stem cells" (see item #3 here which is dentin: https://en.wikipedia.org/wiki/Human_tooth#/media/File:Cross_sections_of_teeth_intl.svg https://en.wikipedia.org/wiki/Human_tooth#/media/File:Cross_...). The dentin stem cells are probably contained within the dentin? They wanted to stimulate the dentin stem cells with the laser light, but there is no way to reach dentin without drilling through the outer tooth enamel. They're not simulating tooth decay, they simply need to get to the dentin. Their conclusion was that this laser treatment "triggered the enhanced dentin formation".
