Ibicuruzwa

Gukora iperereza ku ngaruka za dextranase ya exogenous na sodium fluoride kuri S. mutans monospecies biofilm.S.mutans 25175 yakuze muri tryptone soya broth medium, kandi biofilm yashizwe kumurongo wikirahure hamwe na sucrose 1.0%.Exogenous dextranase na sodium fluoride byongeweho wenyine cyangwa hamwe.Imiterere ya biofilm yasesenguwe na microscopi ya laser ya conocal.Ingaruka z’ibiyobyabwenge kuri adhesion na exopolysaccharide yakozwe na biofilm zasuzumwe no kubara scintillation hamwe nuburyo bwa anthrone. Muri ubu bushakashatsi, twasanze imiterere ya biofilm yambere na biofilm ikuze yahinduwe igice na dextranase hamwe nubushuhe bwinshi bwa sodium fluoride ukwayo.Nyamara, dextranase ifatanije nubushyuhe buke bwa sodium fluoride irashobora gusenya neza imiterere isanzwe yibiti bisa na biofilm, kandi biganisha kuri bagiteri nkeya ugereranije nigihe dextranase cyangwa fluoride byakoreshejwe wenyine (P <0.05).Umubare wa elegitoronike kandi udashobora gushonga exopolysacchari de wagabanutse cyane muguhuza dextranase hamwe na fluoride ya sodium nkeya, kuruta igihe byakoreshwaga wenyine (P <0.05).Aya makuru yerekana ko dextranase hamwe na fluoride ya sodiumi nkeya bishobora kugira ingaruka ziterwa na biofilm ya S. mutans kandi bikerekana ko hashyirwaho ingufu nke za sodium fluoride mukuvura anticaries.
