| Abstract | |
Halitosis is the emanation of offensive odors from nostrils and oral cavity due to volatile sulfur compounds (VSC) production originated from bacterial metabolism, usually related to hygiene or oral alterations. However emotional factors and menstrual cycle have also been associated with the VSC production. In this context, and considering that the gender of the experimenter may influence the responses of the volunteer, the aim this study was to evaluate the influence of the anxiety and experimenter gender on the VSC and salivary biomarkers production. The anxiety was induced by Video-Recorded Stroop Color-Word Test (VRSCWT), validated as a model of experimental anxiety. The VSC concentration and salivary of cortisol, alpha-amylase, secretory IgA (sIgA) and total proteins, as well as, systolic and diastolic blood pressure, heart rate (HR) and salivary flow were evaluated before and after the application of the VRSCWT. Data were compared by Analysis of Variance with Repeated Measures (p<0.05). The VRSCWT induced significant increase in the VSC concentration, in both genders, without influence of the experimenter gender. Women presented higher VSC concentration than men, before and after VRSCWT. The VRSCWT also induced increase in blood pressure in men and women in relation to basal values. The increase in systolic blood pressure was more pronounced when volunteers were evaluated by an experimenter of the opposite gender. Women, when evaluated by the opposite gender, presented a significant increase of cortisol and salivary alpha-amylase in relation baseline values, without changes when the VRSCWT was applied by the evaluator of the same gender, or male volunteers. There was no change on the values of HR, salivary flow, sIgA and total proteins after anxiogenic situation. The results showed that the VRSCWT induced anxiety and increased VSC production and that these effects were influenced by the volunteer and gender of the experimenter. (AU) | |
