CASTILHO, Maria Cristina de Matos et al. Relationship between perceived stress and salivary parameters in women under regular stress conditions. Arq. Odontol. [online]. 2011, vol.47, n.1, pp. 25-30. ISSN 1516-0939.
Aim: To verify the relationship among salivary factors (flow rate, buffer capacity, and alphaamylase activity) and the perceived stress in women, when under basal conditions of stress. Materials and Methods: Fourteen volunteers, students from São Leopoldo de Mandic Faculty, Campinas, SP, females, at an average of 31.4 ± 10.0 years of age, were selected. The salivary flow rate (stimulated and non-stimulated), buffer capacity, activity of salivary alpha-amylase, and the perceived stress (Cohen's questionnaire) were determined. Pearson's coefficient of correlation (R) was applied among the studied factors (a=0.05). Results: Mean ± standard deviation of the results were FSE = 1.28 ± 0.39 ml/ min; FSNE = 0.39 ± 0.18 ml/min; CT = 4.45 ± 1.53; AAS = 16,324.82 ± 12,001.26 U/dl, and EP = 25.62 ± 7.09. A positive, statistically significant correlation between FSE and FSNE (R = 0.5932; p = 0.0325) could be observed. No significant correlations between any other variables could be identified. Conclusion: Under basal conditions of stress, no relationship among salivary flow rate, buffer capacity or alpha-amylase activity, and perceived stress could be observed.
