This study evaluated the effectiveness of antimicrobial photodynamic therapy (aPDT), chlorhexidine (CHX), sodium fluoride (NaF), and hydrogen peroxide (H2 O2 ) for the disinfection of acrylic resin. Methods: In this in vitro experimental study, 100 acrylic resin specimens were randomly divided into five groups (n=20 each): Enterococcus faecalis, Streptococcus mutans, Streptococcus salivarius, Streptococcus sanguinis, and Lactobacillus acidophilus. Each group was immersed separately in 5 mL of microbial suspension. They were then incubated until biofilm formation on their surface. Of each microorganism, one biofilm sample in phosphate-buffered saline was considered as negative control, and other biofilm samples (n=80) were subjected to aPDT with curcumin, 0.12% CHX (positive control), 1% H2 O2 , and 0.2% NaF. Finally, the number of colonies was counted. Data were analyzed by the Kruskal-Wallis and Mann-Whitney tests, two-way ANOVA, and Bonferroni adjustment at a significance level of 0.05. Results: The interaction effect of the treatment modality and type of microorganism was significant on the microbial count (effect size: 0.91, P&lt;0.05). Maximum bacterial proliferation was noted in the following combinations: NaF\/E. faecalis, H2 O2 \/E. faecalis, and H2 O2 \/S. salivarius. Microorganisms had no or insignificant growth and proliferation in the aPDT and CHX groups. Conclusion: The results supported the optimal antimicrobial efficacy of PDT which was comparable to that of CHX. aPDT showed superior antimicrobial efficacy to NaF and H2 O2 for the disinfection of acrylic resin.<\/jats:p>","DOI":"10.34172\/jlms.2023.52","type":"journal-article","created":{"date-parts":[[2023,11,11]],"date-time":"2023-11-11T10:19:30Z","timestamp":1699697970000},"page":"e52","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["In Vitro Comparative Evaluation of the Efficacy of Antimicrobial Photodynamic Therapy, Chlorhexidine, Sodium Fluoride, and Hydrogen Peroxide for Acrylic Resin Disinfection"],"prefix":"10.34172","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0121-3951","authenticated-orcid":true,"given":"Farhad","family":"Sobouti","sequence":"first","affiliation":[{"name":"Dental Research Center, Mazandaran University of Medical Sciences, Sari, Iran"},{"name":"Department of Orthodontics, School of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1239-517X","authenticated-orcid":true,"given":"Sepideh","family":"Dadgar","sequence":"additional","affiliation":[{"name":"Dental Research Center, Mazandaran University of Medical Sciences, Sari, Iran"},{"name":"Department of Orthodontics, School of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8263-9383","authenticated-orcid":true,"given":"Aysan","family":"Salehi","sequence":"additional","affiliation":[{"name":"School of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3209-9845","authenticated-orcid":true,"given":"Nika","family":"Rezaei Kalantari","sequence":"additional","affiliation":[{"name":"Dental Research Center, Mazandaran University of Medical Sciences, Sari, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9284-4352","authenticated-orcid":true,"given":"Mehdi","family":"Aryana","sequence":"additional","affiliation":[{"name":"Student Research Committee, School of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2932-1911","authenticated-orcid":true,"given":"Hamid Reza","family":"Goli","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Virology, School of Medicine, Mazandaran University of Medical Sciences, Sari, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9961-8817","authenticated-orcid":true,"given":"Mohadeseh","family":"Heidari","sequence":"additional","affiliation":[{"name":"Dental Implant Research Center, Dentistry Research Institute, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"20123","published-online":{"date-parts":[[2023,11,4]]},"container-title":["Journal of Lasers in Medical Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/41527\/32433","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/41527\/32433","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,11]],"date-time":"2023-11-11T10:19:30Z","timestamp":1699697970000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/41527"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,11,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.34172\/jlms.2023.52","relation":{},"ISSN":["2008-9783","2228-6721"],"issn-type":[{"type":"print","value":"2008-9783"},{"type":"electronic","value":"2228-6721"}],"subject":[],"published":{"date-parts":[[2023,11,4]]},"assertion":[{"value":"Shahid Beheshti University of Medical Sciences","name":"journal_owner","label":"Journal Owner"},{"value":"Shahid Beheshti University of Medical Sciences","name":"journal_publisher","label":"Journal Publisher"},{"value":"2023-03-05","order":1,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-08-06","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-11-04","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
