In the experimental part, this study examined the possibilities of the light source in photodiagnostics combined with the photodynamic method (PDT) and determined the lower detection limit of the basic photosensitizer in dermatology\u2014protoporphyrin IX (PPIX). The absorption parameters and fluorescence quantum efficiency of PPIX were investigated, and case studies of patients in clinical conditions were presented. A new application may be the use of a Wood\u2019s lamp in dental diagnostics to detect the early stage of caries and to monitor bacterial plaque. Fluorescence area studies were conducted on 21 extracted teeth with different levels of caries. The results showed that changes in enamel demineralization can be detected at a level as low as a 5\u201310% decrease in fluorescence.<\/jats:p>","DOI":"10.3390\/s25113253","type":"journal-article","created":{"date-parts":[[2025,5,22]],"date-time":"2025-05-22T07:04:28Z","timestamp":1747897468000},"page":"3253","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Application of Wood\u2019s Lamp in Dermatological and Dental Photodiagnostics"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4585-1744","authenticated-orcid":false,"given":"Miros\u0142aw","family":"Kwa\u015bny","sequence":"first","affiliation":[{"name":"Institute of Optoelectronics, Military University of Technology, Gen.
