Outline of Final Research Achievements

In this study,we measured VSCs measurements in on 98 patients at a dental clinic.Associations between factors in the two groups were then assessed, with a 5% level of significance.Among these 98 respondents, 28 (29%) were in their 60s, which was the largest age cohort in the study. Significantly higher concentrations of H2S and (CH3)2S were found among smokers (n=40) than nonsmokers (n=58) (p<0.001). For saliva measurements, salivary pH, pH after acid loading, and oral moistness.Differences between smokers and non-smokers were analyzed with the level of statistical significance set at 5%. Salivary pH, pH after acid loading, and salivary flow rate were all significantly lower in smokers (n = 38) than in non-smokers (n = 58) (p < 0.001), and oral moistness was also significantly lower in smokers than in non-smokers (p =0.01). Smokers have significantly lower salivary pH, pH after acid loading than non-smokers.
