Abstract

Aim: To investigate the halitosis level in oral lichen planus (OLP) participants and OLP-free participants. Methods: This cross-sectional study recruited 70 participants at the New Zealand's National Centre for Dentistry. Halitosis was determined using the objective measurements (parts per billion [ppb] volatile sulphur compounds [VSCs] in the exhaled air) and subjective measurement (self-reported halitosis questionnaire). Results: The VSCs values of OLP participants (mean ± SD: 144.64 ± 23.85 ppb) were significantly greater than that in the OLP-free participants (105.52 ± 22.31ppb) (mean difference: 39.12 ppb; p < 0.05; 95% CI: 27.95, 50.29). The VSCs value of hyperplastic (mean difference: 34.11; 95% CI: 20.07, 48.15; p<0.05) and erosive/ulcerative (mean difference: 57.47; 95% CI: 34.19, 80.76; p<0.05) OLP participants were statistically greater than that of OLP-free participants. No statistical significance was found between hyperplastic and erosive/ulcerative OLP (p>0.05). "Type (OLP-free/OLP)" has a significant effect on the dependent variable (VSCs). 78.6% of OLP and 90.5% of OLP-free brushed their teeth at least twice daily, with a statistically significant observation (Mean square: 1.61; F: 13.13; p<0.05). Conclusions: The levels of VSCs were greater in participants with hyperplastic and erosive/ulcerative OLP than that in the OLP-free participants. .

口腔扁平苔藓患者的口臭。

目的：调查口腔扁平苔藓（OLP）患者和无OLP患者的口臭程度：这项横断面研究在新西兰国家牙科中心招募了70名参与者。口臭通过客观测量（呼出空气中的十亿分之挥发性硫化合物[VSCs]）和主观测量（口臭自我报告问卷）来确定：OLP参与者的VSCs值（平均值±标准差：144.64±23.85ppb）明显高于无OLP参与者的VSCs值（105.52±22.31ppb）（平均值差异：39.12ppb；P < 0.05；95% CI：27.95，50.29）。增生的 VSCs 值（平均差异：34.11；95% CI：20.07，48.15；P0.05）。"类型（无 OLP/有 OLP）"对因变量（VSCs）有显著影响。78.6%的 OLP 和 90.5%的无 OLP 每天至少刷牙两次，这在统计学上具有显著意义（均方差：1.61；F：13.05；P：0.05）：1.61; F: 13.13; p

期刊介绍： Journal of Breath Research is dedicated to all aspects of scientific breath research. The traditional focus is on analysis of volatile compounds and aerosols in exhaled breath for the investigation of exogenous exposures, metabolism, toxicology, health status and the diagnosis of disease and breath odours. The journal also welcomes other breath-related topics. Typical areas of interest include: Big laboratory instrumentation: describing new state-of-the-art analytical instrumentation capable of performing high-resolution discovery and targeted breath research; exploiting complex technologies drawn from other areas of biochemistry and genetics for breath research. Engineering solutions: developing new breath sampling technologies for condensate and aerosols, for chemical and optical sensors, for extraction and sample preparation methods, for automation and standardization, and for multiplex analyses to preserve the breath matrix and facilitating analytical throughput. Measure exhaled constituents (e.g. CO2, acetone, isoprene) as markers of human presence or mitigate such contaminants in enclosed environments. Human and animal in vivo studies: decoding the ''breath exposome'', implementing exposure and intervention studies, performing cross-sectional and case-control research, assaying immune and inflammatory response, and testing mammalian host response to infections and exogenous exposures to develop information directly applicable to systems biology. Studying inhalation toxicology; inhaled breath as a source of internal dose; resultant blood, breath and urinary biomarkers linked to inhalation pathway. Cellular and molecular level in vitro studies. Clinical, pharmacological and forensic applications. Mathematical, statistical and graphical data interpretation.
