No ka noiʻi ʻana i nā hopena o ka exogenous dextranase a me ka sodium fluoride ma kahi S. mutans monospecies biofilm.S.Ua ulu ʻia ʻo mutans 25175 i loko o ka tryptone soya broth medium, a ua hana ʻia ka biofilm ma nā kiʻi aniani me ka 1.0% sucrose.Hoʻohui pū ʻia ka dextranase exogenous a me ka sodium fluoride.Ua kālailai ʻia ka biofilm morphology e ka confocal laser scanning microscopy.Ua loiloi ʻia nā hopena o ka lāʻau lapaʻau i ka hoʻopili ʻana a me ka exopolysaccharide e nā biofilms e ka helu scintillation a me ke ʻano anthrone, i kēlā me kēia. sodium fluoride kaawale.Eia nō naʻe, hiki i ka dextranase i hui pū ʻia me ka haʻahaʻa haʻahaʻa o ka sodium fluoride hiki ke hoʻopau maopopo i ke ʻano o ka lāʻau like ʻole o ka biofilm, a alakaʻi i ka liʻiliʻi o ka hoʻopili bacteria ma mua o ka hoʻohana ʻia ʻana o ka dextranase a i ʻole fluoride wale nō (P <0.05).ʻO ka nui o ka exopolysacchari de soluble a me ka insoluble i hoʻemi nui ʻia ma ka hui ʻana i ka dextranase me kahi haʻahaʻa haʻahaʻa o ka sodium fluoride, ʻoi aku ka nui ma mua o ka hoʻohana ʻana iā lākou wale nō (P <0.05).Hōʻike kēia mau ʻikepili i ka dextranase a me ka haʻahaʻa haʻahaʻa o ka sodium fluoride hiki ke loaʻa nā hopena synergistic e kūʻē i ka biofilm S. mutans a manaʻo e hoʻohana i kahi haʻahaʻa o ka sodium fluoride i ka mālama anticaries.
