Regenerative approaches to tooth repair often involve the use of invasive and complex procedures such as cell transplantation or the controlled delivery of growth factors. A Harvard University team believes that it has identified a simpler solution-low-power laser treatment-that can induce stem cell differentiation in dental tissue.¹

It remains to be seen whether the approach can restore functional dentin in human teeth and the extent to which it can induce differentiation in additional cell types...
