Surface morphology and elemental composition were analyzed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), and antimicrobial and antibiofilm activity was quantified by determining the number of colony-forming units (CFU\/mL) for Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecalis), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and fungi (Candida albicans, C. parapsilosis). FOZ exhibited a very rough surface rich in zinc, associated with the most pronounced reduction in microbial adhesion; CIS showed a relatively compact ionomer matrix with barium-rich domains and good antibiofilm activity, particularly against P. aeruginosa, while DT exhibited a predominantly organic, smooth surface with isolated inorganic aggregates and a more pronounced inhibition profile against E. coli. The results indicate that the microstructure and surface chemical composition of the cements directly influence the pattern of microbial colonization and antibiofilm efficacy, providing a rationale for selecting the cementing material based on microbiological risk and specific clinical conditions.<\/jats:p>","DOI":"10.47162\/rjme.67.1.17","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T22:55:06Z","timestamp":1784328906000},"page":"169-177","source":"Crossref","is-referenced-by-count":0,"title":["SEM evaluation of dental cement surface morphology and microbial adhesion \u2013 a comparative study"],"prefix":"10.47162","volume":"67","author":[{"name":"Faculty of Dental Medicine, Titu Maiorescu University of Bucharest, Romania","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George Andrei","family":"Petrescu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cornelia Ioana","family":"Ilie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Science and Engineering of Oxide Materials and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania; National Research Center for Micro and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian Ionu\u0163","family":"Nicoar\u0103","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Science and Engineering of Oxide Materials and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania; National Research Center for Micro and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roxana","family":"Tru\u015fc\u0103","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"National Research Center for Micro and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir Lucian","family":"Ene","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Science and Engineering of Oxide Materials and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania; National Research Center for Micro and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ionela Andreea","family":"Neac\u015fu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Science and Engineering of Oxide Materials and Nanomaterials, Faculty of Chemical Engineering and Biotechnologies, National University of Science and Technology Politehnica Bucharest, Romania; National Research Center for Micro and Nanomater","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anamaria","family":"Bechir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Faculty of Dental Medicine, Titu Maiorescu University of Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"26736","published-online":{"date-parts":[[2026,7,2]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"\"[1] Garg P, Klineberg I.
