Establishment of a Quantitative Method for the Extraction of Nicotine and Cotinine in Gingival Tissue and Relationship Between Gingival Intoxication With Conventional Smoking Biomarkers: A Pilot Study
Objectives
Smoking is considered a major risk factor for periodontitis genesis and progression. In clinical studies, specific indicators have been used to characterize the smoking status of the patient as the number of cigarettes consumed (NCC), the pack-years (PY), or Fagerström Test for Nicotine Dependence (FTND). However, available literature is missing on the relationship between cotinine gingival intoxication and smoking indicators. First, the development of a quantitative method for the extraction of nicotine and cotinine in gingival tissue. Second, to investigate the relationship between gingival intoxication and conventional smoking biomarkers.
Material and Methods
Fourteen smoker patients were included in the study. After clinical data collection, salivary and gingival samples collection, toxicological analyses were performed using liquid extraction after enzymatic digestion (subtilisin) and ultra-performance liquid chromatography coupled to mass spectrometry (UPLC-MS/MS).
Results
Gingival cotinine quantification was successfully performed in 14 samples (100%) with a mean of 0.280 ng/mg (range = 0.094–0.505). Only FTND was statistically associated with gingival cotinine levels (p = 0.0072; r² = 0.60). Gingival nicotine quantification was achieved in 12 of the 14 gingival samples (86%) with a mean of 0.384 ± 1.00 ng/mg (range = 0.03–3.84). Gingival nicotine was statistically associated with NCC (p = 0.032; r² = 0.55), PY (p = 0.0011; r² = 0.76), and FTND (p = 0.016; r² = 0.60). Salivary nicotine and cotinine levels were statistically associated with, respectively, NCC (p = 0.030; r² = 0.34), and NCC (p = 0.0094; r² = 0.63) + PY (p = 0.0078; r² = 0.64).
Conclusions
This pilot study established a quantitative extraction method for nicotine and cotinine from human gingival samples. Additionally, FTND was associated with gingival cotinine. However, further large-scale studies are needed to confirm the relationship between nicotine dependence and gingival intoxication.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
