Oversigtsartikel

I fremtiden vil en større del af verdens drikkevand komme fra afsaltet havvand og brakvand. Inden det afsaltede vand kan bruges som drikkevand, skal det først tilføres ioner for at forbedre dets smag og ned- sætte dets korrosive potentiale. Med hensyn til ca- ries vides kun meget lidt om effekten af andre ioner end fluorid i drikkevand. Derfor har vi her undersøgt effekten af 22 almindelige fysisk-kemiske karakte- ristika ved drikkevand, herunder ioner, gasser, orga- niske forbindelser og fysiske mål, på DMFS blandt 15-årige skolebørn i Danmark. Ved iterativ søgning og testning fandt vi, at kalcium sammen med fluorid kunne forklare 45 % af variationen i DMFS blandt 52.057 15-årige skolebørn i 249 danske kommuner. Begge ioner i drikkevand reducerer DMFS uafhængigt af hinanden og kan derfor anvendes i kombination til udvikling af drikkevand med optimal carieshæm- mende effekt.
