Allergic reactions on the new and old teeth prostheses

To compare the possibility of allergic reactions on the new and old teeth prostheses we tested 3 groups of patients. Group I (15 patients)had new protheses (1-6 months old), group II (15 patients) had old ones (6 months-5years) and group III (control group of 10 volunteers) had five people with new one and five with old one protheses. Allergic reactionwas found by clinical and pathological tests on oral mucosa. S mears from oral mucosaand also fromprostheses material was cultivated on Sabouraud agar to isolate colony of Candida and on blood agar to isolate bacteria colony. To found possible allergic reaction on prostheses material we provided patch test with specimens of old or new prosthesis + tests in chromium, nickel, molybdenum and acrylates and by Candidin and bacterial vaccina intradermal (i.d.) test to confirmed positive reaction on this microorganisms. The results showed that in group 14 patients had a positive reaction on acrylates, 2 on chromium, nickel, and molybdenum and 3on both and only one was positive on new prosthesis material. Smearsfrom mouth were in one positive on Candida in 2 on mixed Gram+ and Gram- microorganisms and in other negative (saprophytes). Candidin and bacterial vaccine i.d. test were in all negative. In group II 8 patients were positive on old prosthesis material, 2 on acrylates asnd on Cr, Ni, Mo legure. From smears in thesen group we isolated in 9 mixed Gram+ and Gram- microorganisms (on blood agar), 4 Candida (Sabouraud agar) and others wre negative. We found also mycotic elements and bacteria in particles of prosthesis material in 4 cases. Candidian and bacterial vaccina i.d. test were positive in 10 patients. In control, group III only one showed positive reaction on acrylates and smears were positive on bacteria and mycotic elements in all 5 having old orosthesis. Candidin and bacterial vaccina i.d. test were positive in 3 of them. So we conclude that pathological reactions in group I is true allergy on matherial from which prosthesis was made and and in group II we have more often toxo-allergic or pseudoallergic on bacteria and mycitic elements both in mouth or prosthesis material.
