Having an option other than crowning to treat cracks would be a game-changer, especially since the AAE not long ago put out a policy paper recommending that all teeth with cracks (even asymptomatic) receive crown coverage, which is both costly and presents a risk of inducing irreversible pulpitis and subsequent necrosis in the tooth (due to the heat and mechanical trauma of the crown prep.).
