This study aims to analyze saliva composition in crack users using vibrational spectroscopy.
A total of 90 participants were meticulously selected and divided into three groups, each comprising 30 individuals. All participants met the criterion of having no observable clinical changes in the oral mucosa. The groups included active crack users with a minimum usage duration of 30 days, ex-crack users, and non-crack users. Rigorous inclusion and exclusion criteria were applied during participant selection to ensure the study's precision. Saliva analysis was performed using vibrational spectroscopy with FTIR (Fourier-transform Infrared spectroscopy).
Pre-processed spectra enabled statistical comparability. Salivary biomarkers revealed clinical implications, including findings related to xerostomia, caries, and periodontal or systemic conditions such as lung cancer.
The research uncovers significant compositional differences in the saliva of current users, former users, and non-users of crack. This nuanced understanding contributes to the discourse on substance abuse, highlighting the potential of saliva analysis for discerning different stages of crack use. The investigation suggests options for further exploration in clinical and forensic contexts, promising advancements in addiction research and diagnostics.
本研究旨在利用振动光谱分析可卡因吸食者的唾液成分。
共精心挑选了90名参与者,分为三组,每组30人。所有参与者均符合口腔黏膜无明显临床变化的标准。这些组包括使用可卡因至少30天的现用者、曾用者和未使用者。在参与者选择过程中应用了严格的纳入和排除标准,以确保研究的准确性。使用傅里叶变换红外光谱(FTIR)振动光谱对唾液进行分析。
预处理后的光谱实现了统计可比性。唾液生物标志物揭示了临床意义,包括与口干、龋齿以及肺癌等牙周或全身疾病相关的发现。
该研究揭示了可卡因现用者、曾用者和未使用者唾液成分的显著差异。这种细致入微的理解有助于有关药物滥用的讨论,突出了唾液分析在辨别可卡因使用不同阶段方面的潜力。该调查为临床和法医背景下的进一步探索提供了选择,有望在成瘾研究和诊断方面取得进展。
