Reactivity of aragonite with dicalcium phosphate facilitates removal of dental calculus

Editorial summary

This in vitro study examines how aragonite interacts with dicalcium phosphate and whether that interaction can facilitate removal of dental calculus. Surface characterization and controlled brushing experiments were used to assess changes in calculus and the effects of the abrasive treatment on tooth substrates. The investigators related chemical and surface changes to the subsequent mechanical removal process, while considering enamel and dentin. The findings concern the behavior of the tested materials under laboratory conditions. They provide evidence for evaluating a dental abrasive mechanism rather than establishing clinical effectiveness in a patient population.
