Erratum to: A novel approach to evaluate the effect of medicaments used in endodontic regeneration on root canal surface indentation

The original version of this article inadvertently contained a mistake. Unfortunately, there is a typo in the equation used to estimate the hardness values, the last "multiplication" sign should be a "plus" sign. The correct equation is shown here.

$$ \mathrm{Hardness}=\mathrm{P}/\left(\pi \times \mathrm{r}\times \sqrt{{\mathrm{r}}^2+{\mathrm{h}}^2}\right) $$
