Over the years, welding fumes' harmful effects have been demonstrated countless times in the scientific literature. Recently, studies in the field have shown an increasing interest in the negative consequences that these fumes may have on the tissues of the oral cavity. The current study aimed to investigate the impact that welding fumes have on the structure of human dental enamel by analyzing the microhardness of the dental enamel in 15 extracted human teeth, after various exposure times, using the Vickers method. The results obtained after 48, 96, 168, and 336 h of direct exposure of the extracted specimens to the welding fumes show a statistically significant increase in the depreciation of the dental enamel's microhardness, related to the duration of exposure ( < 0.05). An average of 305 Vickers units was observed at the longest exposure time, 336 h, in the present study, whereas in the control group, the microhardness analysis showed an average of 327 Vickers units.
多年来，焊接烟尘的有害影响在科学文献中已被无数次证明。最近，该领域的研究表明，人们越来越关注这些烟尘可能对口腔组织产生的负面影响。本研究旨在通过使用维氏硬度测试法，分析15颗拔除的人牙在不同暴露时间后牙釉质的显微硬度，来研究焊接烟尘对人牙釉质结构的影响。将拔除的样本直接暴露于焊接烟尘中48、96、168和336小时后获得的结果表明，牙釉质显微硬度的降低与暴露时间相关，具有统计学意义（<0.05）。在本研究中，最长暴露时间336小时时平均观察到305维氏硬度单位，而在对照组中，显微硬度分析显示平均为327维氏硬度单位。
