More than 200 patients with a suspected allergy caused by dental materials attended the outpatient allergy clinic of the Dental Hospital at TMDU every year. We have been developing allergy testing, diagnosis, and allergen control treatment, especially on metal allergy with good cure rate. Objectives: The aim of this study was to determine the relevance of developing metal allergy lesion and wearing metallic accessories, which will affect the possibility of sensitization by same element as in dental alloys. Methods: We investigated 655 patients (500 female, 155 male, age average: 47.2 ) who attended our allergy clinic during 1999 - 2000. We focused on the patients who have previous history of accessory dermatitis and examined their status of lesions, patch test positive metal elements. Results: 37.4% of patients have experience of accessory dermatitis and the frequencies of pustulosis palmaris et plantaris, contact dermatitis were highly ranked. Patch test positive rates was 49.4% and Ni rose significantly and Co, Hg, Cr, Pd followed. Conclusions: Though it is difficult to simply compare the incidence of metal allergy caused by metallic accessory and dental alloys, these findings indicate the metallic accessory may seriously affect the criteria of dental material selection and treatment planning.
