In this newsletter, an alternative antibiotic treatment like antimicrobial photodynamic therapy (aPDT) is presented. This method may reduce the need for antibiotics and reduce the risk for antibiotic resistance.

One of NIOM’s many research methods are also highlighted; Western blotting is a common method to identify and quantify level-changes of proteins in tissues and cells exposed to possible toxic compounds. The results from experiments using this method may elucidate the mechanisms behind toxic effects of dental materials.
