Sažetak

Type IV reactions, reactions of delayed hypersensitivity, are manifestations of cellular immunity. Such reactions are caused by sensitised T-lymphocytes. In dental medicine contact sensitivity is of particular interest, as restorations are in long-term direct contact with oral tissues and saliva and during function they wear and bend, leading to corrosive processes which result in the release of ions, their accumulation in the tissues and possible sensitivity, i.e. allergic reaction. Dentists need to chose alloys with less tendency to the release of ions, in other words good biotolerance. It is recommended that the use of alloy with a high share of nickel should be avoided. Patch test is indicated for all patients with a history of hypersensitivity to metal or other materials used in the construction of a prosthetic restoration.
