Sigusch BW, et al. - Researchers developed a polymeric bone grafting material of suitable physical appearance and antimicrobial photodynamic activity. Excellent mechanical and cytocompatible properties were demonstrated by both materials. Moreover, significant bacterial suppression was induced by irradiation with 652nm. A more efficient cure of periodontal bone lesions could be enabled by the manufactured biomaterials. An increase in the functional stability was possible by the mechanical properties. Also, data suggested the antimicrobial action of the materials upon illumination with light that enables a trans-mucosal eradication of residual pathogens.
