[The interrelation between allergic reactions to dentures made of stainless steel and the skin hypersensitivity to Cr and Ni].

Twenty-two patients with stainless steel dentures, suffering from skin sensitization to chromium and nickel, were examined. The majority of these patients wore the dentures without complaining of local or general pathologic reactions. In three allergic catarrhal glossitis, aphthous stomatitis, and dermatitis were diagnosed.

[The incidence of intolerance for stainless-steal dentures based on data from a questionnaire and from clinical laboratory research methods].

Questionnaires were distributed among 1042 patients with stainless steel dentures. 178 of these complained of symptoms characteristic of denture intolerance. Clinical examinations, pH-metry of mixed saliva and stationary potential of the dentures, epicutaneous allergologic tests, and removal of dentures in intricate cases to specify the diagnosis have revealed intolerance of electrogalvanic nature in 62 patients.

[The diagnostic value of epicutaneous tests in intolerance for dentures made of stainless steel].

A total of 19 patients with stainless denture intolerance were examined. In addition to the routine stomatological examination, the authors determined pH of mixed saliva, measured the steady-state potentials of dentures, and performed epicutaneous tests with samples made of stainless steel, chromium and nickel. In all the patients, the epicutaneous tests with chromium and/or nickel were positive, those with stainless steel were negative.

[Allergy to gold--a cause of denture intolerance].

Two cases of allergic responses to "dentistry gold" are reported. The condition was confirmed in epicutaneous tests with 2 different gold--containing substances. Removal of the dentures was the cure for these patients.
