The invention relates to a light-curing composition for producing dental components in a DLP method or SLA method, comprising, in relation to the total mass of the light-curing composition: a liquid monomer composition with a mass fraction of 60% or more, comprising one or more radically polymerizable monomers, one or more photoinitiators with a combined mass fraction in the range from 0.001 to 10%, and solid polymer particles with a particle diameter in the range from 0.4 to 4 μm and a combined mass fraction in the range from 0.1 to 30%, wherein the solid polymer particles are dispersed in the liquid monomer composition.

A method of applying a two-part dental sealant is described comprising providing a syringe device (1) comprising a cartridge (10) including first and second chamber. The first chamber contains a first part of a dental sealant comprising a (meth)acrylate resin and an oxidizing curing agent. The second chamber contains a second part of a dental sealant comprising a (meth)acrylate resin and a reducing curing agent that reacts with the oxidizing curing agent of the first chamber. The first and/or second part of the dental sealant further comprise a single component or multiple components that neutralize acid and promote remineralization. The syringe device comprises a dispensing nozzle (17) comprising a static mixer and an outlet at one end of the cartridge and a plunger (20) at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.
