Txhawm rau tshawb xyuas qhov cuam tshuam ntawm exogenous dextranase thiab sodium fluoride ntawm S. mutans monospecies biofilm.S.mutans 25175 tau loj hlob hauv tryptone soya broth nruab nrab, thiab biofilm tau tsim ntawm iav slides nrog 1.0% sucrose.Exogenous dextranase thiab sodium fluoride tau ntxiv ib leeg lossis ua ke.Lub biofilm morphology tau soj ntsuam los ntawm confocal laser scanning microscopy.Cov teebmeem ntawm cov tshuaj ntawm cov adhesion thiab exopolysaccharide ntau lawm los ntawm biofilms tau soj ntsuam los ntawm scintillation suav thiab anthrone txoj kev, raws li nyob rau hauv txoj kev tshawb no, peb pom tias tus qauv ntawm thawj biofilm thiab mature biofilm yog ib feem hloov los ntawm dextranase thiab siab concentrations. sodium fluoride cais.Txawm li cas los xij, dextranase ua ke nrog qis qis ntawm sodium fluoride tuaj yeem rhuav tshem cov qauv ntoo zoo li biofilm, thiab ua rau cov kab mob adhesion tsawg dua thaum siv dextranase lossis fluoride ib leeg (P <0.05).Cov nyiaj soluble thiab insoluble exopolysacchari de tau txo qis los ntawm kev sib xyaw dextranase nrog qis concentration ntawm sodium fluoride, ntau dua li thaum lawv siv ib leeg (P <0.05).Cov ntaub ntawv no qhia tau hais tias dextranase thiab qis concentration ntawm sodium fluoride tej zaum yuav muaj kev sib koom ua ke tiv thaiv S. mutans biofilm thiab qhia txog kev siv cov tshuaj sodium fluoride tsawg hauv kev kho cov kab mob.
