There is a gap in the literature concerning the chemical effects that household products may produce on human remains. The present study examines the effects of household chemical products on teeth. A total of eight chemicals were utilized for this experiment. The corrosive chemical categories include: hydrochloric acid, sulfuric acid, phosphoric acid, and sodium hydroxide. Two products with each chemical were used, each representing varying concentrations of the corrosive product. Two human teeth were allocated for emergence in the chemical throughout a 24-h period of exposure. Results demonstrate hydrochloric acid as the most detrimental chemical to the dental samples. Sulfuric acid enacted minimal alterations to the teeth, although some etching and discoloration were noticeable. Phosphoric acid resulted in variable changes of the organic and inorganic contents of teeth. Lastly, exposure of sodium hydroxide resulted in little to no change. As hypothesized, distinct effects are observable of each chemical.
关于家用产品可能对人类遗骸产生的化学影响,文献中存在空白。本研究考察了家用化学产品对牙齿的影响。本实验共使用了八种化学物质。腐蚀性化学物质类别包括:盐酸、硫酸、磷酸和氢氧化钠。每种化学物质使用两种产品,每种代表不同浓度的腐蚀性产品。在24小时的暴露期间,分配两颗人类牙齿使其暴露于化学物质中。结果表明,盐酸对牙齿样本危害最大。硫酸对牙齿造成的改变最小,不过仍有一些蚀刻和变色现象明显可见。磷酸导致牙齿的有机和无机成分发生了不同程度的变化。最后,氢氧化钠的暴露几乎没有导致变化。正如所假设的,每种化学物质都有明显的影响。
