We investigated the effect of TiO2 on the adherence of S. mutans to a dental pit and fissure sealant containing powdered semiconductor TiO2, which exhibits a photocatalytic reaction. The viability of S. mutans on the sealant containing TiO2 varied with the bacterial strain. The adherence to the sealant was greatest for S. mutans Ingbritt, followed in order by S. mutans NCTC 10449 and S. mutans GS-5. TiO2 increased the Brinell hardness number of the sealant, although the flexural strength decreased.
