Abstract
Svrha istraživanja bila je ocijeniti i usporediti antibakterijsku učinkovitost pet retrogradnih punila korijenskih kanala. Materijal i metode: Metodom difuzije u agru ocijenjena je zona inhibicije bakterijskog rasta na podlozi pet retrogradnih punila korijenskih kanala: Pro Root MTA, cementa Portland, Super-EBA, IRM-a, Sealera 26 te amalgama. Za ciljane mikroorganizme bilo je odabrano pet anaeroba (Porphyromonas gingivalis, Parvimonas micra, Fusobacterium nucleatum, Propionibacterium acnes i Eubacterium saburreum) te dva fakultativna (Actinomyces viscosus i Enterococcus
faecalis). Rezultati: Sealer 26 postigao je najveću inhibiciju rasta. Punila IRM i Super-EBA spriječila su rast samo Porphyromonas gingivalis, ali učinak je bio znatno slabiji u usporedbi s djelovanjem
Sealera 26. Kao neučinkovita antibakterijska sredstva pokazali su se MTA, cement Portland i amalgam. Zaključak: Rezultati istraživanja potvrdili su da Sealer 26 ima najjače antibakterijsko djelovanje u usporedbi s ostalim često upotrebljavanim apikalnim punilima korijenskih kanala.Purpose: The present study was undertaken to evaluate and compare the antibacterial effectiveness of five root-end filling materials. Material and methods: The agar diffusion method was employed to evaluate the inhibition zone provided by the following root-end filling materials: Pro Root MTA, Portland cement, Super-EBA, IRM, Sealer 26, and silver amalgam. The target microorganisms included five anaerobic bacterial species (Porphyromonas gingivalis, Parvimonas micra, Fusobacterium nucleatum, Propionibacterium acnes and Eubacterium saburreum) and two facultative bacterial species (Actinomyces viscosus and Enterococcus faecalis). Results: Sealer 26
demonstrated the largest inhibitory effects on all species tested. IRM and Super-EBA were inhibitory only to P. gingivalis, but this effect was far less pronounced as compared to Sealer 26. MTA, Portland cement, and amalgam proved ineffective against all species tested. Conclusion: These findings revealed that Sealer 26 has more pronounced antibacterial effects when compared to other commonly used root-end filling materials
