Abstract
In dentistry, precious metal alloys are, mainly due to economic factors, increasingly displaced by alternatives containing Ni-Cr-Co. There are some reports where hypersensitive reaction to Ni-Cr-Co alloys are presented and discussed. The
reactions reported vary from mucosa contact stomatitis to generalized dermatitis without any oral mucosal reaction. The purpose of this study was to investigate the incidence of nickel, chrome, cobalt and copper, and to know whether subjects with positive skin reaction to nickel would also demonstrate adverse intraoral reaction to a non-precious metal nickel.
The patch tests wee performed in 81 subjects(male 39, female 42) and nickel sulfate 5% aq., potassium bichromate 0.5% aq., cobalt chloride 2% aq., & copper sulfate 1% aq., were used for test allergens And then the intraoral tests were performed in 16 subjects, 8 subjects with positive allergic skin reaction to nickel and 8 subjects with negative allergic skin reaction. A pure metallic nickel plate was attached to the buccal side of the upper second premolar. @ES The results are as follows : @EN 1. He frequency of nickel sensitivity was 9.9% (2 men, 6 women), cobalt was 4.9% (1 man, 3 women) and chrome was 2.5% (2 men) respectively and there was no positive reaction to copper 2. The positive reactions were 8 of 23 (34.8%) with a history of jewelry allergic reactions and 3 of 58 (6.1%) without a history of jewelry allergic reactions. 3. Three of 8 subjects with positive skin reaction gave reactions to the metal plates.
