Sensitization and allergic lesions resulting from metals in our living environment have often been reported. However, dentists have paid little attention so far on sensitization or dermal or mucosal lesions caused by metal restorations. We have established a team of 14 research institutions to perform patch tests with 18 kinds of dental metals and to conduct and epidemiological survey on the patch test positive subjects.Prior to the study, application of the testing solutions and reading of the skin reactions were standardized. Patch tests were done on volunteers and patients with the total of 1, 728 subjects. On those patients who showed positive reactions to the patch tests, metal analysis for the intraoral restorations was done by the method developed by Inoue et al. The analysis results were then compared to the patch test results to investigate the relation between the two.The following data was collected and discussions were made:(1) patch test posit ive/negative rates for the total subjects, (2) their differences regarding sex, age, or a kind of metal, (3) regional dfference, (4) relation between an individual with patch test positive result and his/her intraoral metal restoration (s), (5) types and locations of the lesions, (6) patch test positive rate (overall and of the each metal) for the patient group, (7) difference in the patch test positive rate between the volunteer group and the patient group, (8) comparison between the patch test positive rates among the M-9, M-11 or M-13 series, and among the different concentrations of the testing solutions, (9) comparison of the results between patch tests and their confirmation tests, (10) changes in the patch test reaction during the testing period.From these results, it is considered that careful and adequate measures against the metal allergy should be taken, when the dentist starts the prosthodontic treatment.

今年度から本誌に「依頼論文」欄を新設しました.そのために編集委員会の中に「企画小委員会」を設け,本学会で以前発表されたシンポジウムなどから特に1.トピック的なテーマ,2.総説的で系統的なテーマを決定し,代表執筆者に原稿のご執筆をお願いして本誌に順次掲載することになりました.したがって,本論文は,いわばこれらの企画の第一号であり,以前井上先生により報告された宿題講演の主旨をまとめられたものであります.金属アレルギー問題はタイムリーなテーマであり,本論文には日常の補綴臨床にたずさわるわれわれ臨床家にとってきわめて有意義な情報が提示されています.本研究の代表者である井上先生ならびに共同研究者の諸先生方のご努力に対して改めて敬意をします.

Allergies caused by metals have been increasing. The number of patients visiting dentists with the chief complaint of metal allergy has also been increasing. From March 1994 to February 1997, 263 patients who complained of various symptoms visited our allergy clinic. Among them, 184 patients were suspected to have allergy caused by metals in dental restoration materials and were referred to the patch test. Among 165 patients', 128 were positives for metal allergy. Constituent elements of intraoral metals were analyzed in 107 of these 128 positive patients. The findings were as follows:1. The most common five elements acting on the patients were Hg, Co, Ni, Cr, and Pd.2. The most frequently used elements of dental restoration metal materials were Zn, Ag, Cu, Au, and Pd, and the alloy was Au-Ag-Pd alloy.3. The highest tendency of coincidence between allergen and intraoral metals were observed among Co-Cr-Ni alloys and Pd, Ni, and Cr elements.4. In case of palmoplantar pustulosis, allergen metals tended to be the same as intraoral metal elements.

歯科用金属に起因すると考えられる金属アレルギーが注目されており,その診断にパッチテストが用いられている.しかし,判定は主観に頼り,皮膚の変化を的確,経時的に把握することは困難である.本論文はパッチテストにおける客観的な判定システムを開発することを目的として,パッチテスト後の皮膚色を分光測色し,色彩学的に分析したものである.その結果,皮膚の発赤反応に色彩学的に特徴のある変化が観察された.皮膚の発赤反応を判定する客観的指標を示したものとして興味深い.
