Abstract

Characterization of materials used in dental restorations and fixed prostheses is useful for personal identification. This study investigated the dental treatment trends and use of metal materials among non-Japanese Asian temporary residents and Japanese individuals aged from 20 to 40 years living in a city in Japan. Analysis of 38 participants from different Asian countries showed prominent use of resin fillings, with metal element analysis revealing nickel-chromium (Ni-Cr) or cobalt-chromium (Co-Cr) alloys. Among five Japanese participants of the same age with dental metal treatment scars, resin fillings and silver-palladium-copper-gold (Ag-Pd-Cu-Au) or silver-indium (Ag-In) alloys were observed. This study suggested some regional differences in dental material choices in Asia.

基于 38 个病例研究的 20 多岁至 40 多岁暂居日本的亚洲人口腔中牙科材料的特征。
牙科修复体和固定义齿所用材料的特征有助于个人识别。本研究调查了居住在日本某城市的 20 至 40 岁非日本籍亚洲临时居民和日本人的牙科治疗趋势和金属材料的使用情况。对来自不同亚洲国家的 38 名参与者进行的分析表明,他们主要使用树脂补牙,金属元素分析显示他们使用镍铬(Ni-Cr)或钴铬(Co-Cr)合金。在五名有牙科金属治疗疤痕的同龄日本参与者中,发现了树脂补牙和银-钯-铜-金(Ag-Pd-Cu-Au)或银-铟(Ag-In)合金。这项研究表明,亚洲地区在牙科材料的选择上存在一些地区差异。
