I.PurposePurpose of this research is to study the electrolysis stability of metallic restorations in the patients of dental-metal-allergy and control subjects. Electromotive forces of metallic restorations were observed in these two groups. Relationship between allergic metals and the electrolysis stability of metallic restorations was also investigated.II.Materials and MethodsTwenty-three dental-metal-allergy suspected patients who visited Department of Fixed Prosthodontics, Tokushima University Hospital from December 2003 to June 2004 were participated in this research project. Twenty-three adult volunteers without sighs and symptoms of dental-metal-allergy were selected for the control group. Informed consents were taken from all subjects before go through the clinical investigations.Intra-oral examinations were done for all subjects and DMA meter (Morita Co., Dental Metal Activity Meter JS2002) was utilized to evaluate the electromotive forces of the metallic restorations of these … More subjects. Patch test that identifies allergic metals was performed for the suspected patient group.III.Results and DiscussionFor the most part of the restorations, DMA meter recorded ‘metastable' electrolysis stability. Then ‘active' restorations are found and a few restorations showed ‘stable' conditions.‘Active' metals were frequently found in amalgam and Ni-Cr alloy restorations, while the most of the platinum alloy and bond-HI-precious alloy restorations showed ‘stable'. Many of other restorations made with gold-silver-palladium alloy, gold alloy, silver alloy and Co-Cr alloy exhibited ‘metastable'.According to patch test investigation, the suspected patients group was divided into dental-metal-allergy group and patch test negative group. Comparison of the electrolysis stability of metallic restorations was done between the dental-metal-allergy group and the control group that consisted of volunteers and patch test negative patients. The ‘active' bond-HI-precious alloy restorations were found in the dental-metal-allergy patients group.Because of the limited number of the patients, we could not evaluate the affect of the metallic restorations stability on their allergic symptoms. Further investigations will be required to clarify the relationship of dental materials and allergy symptoms. Less

该研究的螺旋杆菌是研究金属修复体的电解稳定性和牙齿金属过敏和对照受试者的稳定性。在这两组中观察到金属还原的电动力。还研究了过敏金属与金属修复体的电解稳定性之间的关系。II.材料和Methodsstwiend-33-牙齿 - 金属过敏可疑患者，他们从2003年12月至2004年6月参观了Tokushima University Hospital toperthodontons，从2003年12月至2004年6月参与了这项研究项目。对照组选择了23名没有叹息的成年志愿者和牙科金属过敏的症状。在进行临床研究之前，请从所有受试者中获取知情同意。对所有受试者进行了口语检查，并利用了DMA仪表（Morita Co.，Morita Co.，牙科金属活性仪表JS2002）来评估这些受试者金属修复的电子力量……更多受试者。针对可疑患者组进行过敏金属的斑块测试。iii.Results和讨论的大部分还原，DMA仪表记录了“亚稳定”电解稳定性。然后找到“主动”修复体并显示一些“稳定”状态。在汞合金和NI-CR合金修复体中经常发现“稳定”金属，而大部分的铂金合金和键合的合金还原显示出“稳定”。其他许多由金丝 - 铝合金，金合金，银合金和co-cr合金暴露的“亚稳态”制成的修复体。根据贴剂测试研究，可疑患者组分为牙科金属过敏组和补丁测试负面组。在牙齿金属过敏组和由志愿者组成的对照组之间进行了金属修复体的电解稳定性的比较。在牙科金属过敏患者组中发现了“活跃的”粘结 - 纯净合金修复体。由于患者数量有限，我们无法评估金属修复体稳定性对其过敏性症状的影响。需要进一步研究以阐明牙科材料和过敏症状的关系。较少的
