The authors wish to inform the readers of a needed clarification in this manuscript regarding the Acknowledgments section of their article. The National Institute of Dental and Craniofacial Research (NIDCR) is the funding source for their work and they have now noticed that the grant number indicated in the Acknowledgments section of their article recently published in Dental Materials is incorrect. Instead of DE019932, it should be DE019972 .
The authors would like to apologize for any inconvenience caused.
