Poroscopy is the specialized study of sweat pores found on the papillary ridges of the skin. However, the science of poroscopy is not being used to its full potential. The present study was conducted with the goal to assess the effect of immersing hand in water at various temperatures i.e., room temperature (20-30 °C), hot temperature (40-50 °C), and cold temperature (0-10 °C), for 1, 5 and 10 min, on the reproducibility of pore microfeatures namely, area, inter-distance, and angle, in an attempt to demonstrate their reliability in fingerprint matching. As far as the authors are aware, no prior research has attempted to evaluate the impact of immersing hand in water, at different temperatures, on the reproducibility of third level details. Statistical analysis of data revealed that pore inter-distance and angle were reproducible in nature thereby, highlighting their significance in fingerprint matching.
毛孔检验法是对皮肤乳头嵴上发现的汗孔进行的专门研究。然而，毛孔检验学并未得到充分利用。本研究的目的是评估将手浸入不同温度（即室温（20 - 30°C）、热温（40 - 50°C）和冷温（0 - 10°C））的水中1、5和10分钟，对毛孔微观特征（即面积、间距和角度）再现性的影响，以试图证明它们在指纹匹配中的可靠性。据作者所知，此前没有研究试图评估将手浸入不同温度的水中对三级细节再现性的影响。数据的统计分析表明，毛孔间距和角度在本质上是可再现的，从而突出了它们在指纹匹配中的重要性。
