Coltosol F is a moisture-curing, radio-opaque, white temporary filling material designed for short-term dental applications, lasting 1–2 weeks. It is a zinc oxide/zinc sulphate-based cement used for temporary fillings in Class I and II cavities and for temporary sealing in endodontic procedures.
Coltosol F hardens by absorbing moisture, providing a dense, secure marginal seal. However, care should be taken with thin enamel margins, as expansion during hardening may cause fractures.
