Abstract

Introduction: 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. Materials & method: 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. Results: 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 (p < 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.

焊接烟尘对人体牙釉质的危害--显微硬度分析。

导言：多年来，科学文献无数次证明了焊接烟雾的有害影响。最近，该领域的研究表明，人们越来越关注这些烟雾可能对口腔组织造成的负面影响。材料和方法：本研究旨在使用维氏方法分析 15 颗拔出的人类牙齿在不同暴露时间后牙釉质的显微硬度，从而研究焊接烟尘对人类牙釉质结构的影响。结果显示将拔出的试样直接暴露在焊接烟尘中 48、96、168 和 336 小时后得出的结果显示，牙釉质显微硬度的下降与暴露时间的长短有显著的统计学关系（p < 0.05）。在本研究中，在暴露时间最长的 336 小时内观察到的平均值为 305 维氏单位，而在对照组中，显微硬度分析显示平均值为 327 维氏单位。
