Objective. Aim of this study was to characterize the protein profile of whole saliva in partial and complete edentulous and determine the changes in salivary protein expression of adults with varying degrees of tooth loss. Methods. In this observational study, unstimulated saliva samples were collected from 80 adults (age 18-73 years), 20 dentulous and 60 edentulous. Partial and complete edentulous patients (EP) were divided into three groups with different number of teeth lost. Concentration and electrophoretic profile (cellulose acetate membrane and polyacrylamide gels) of the salivary proteins were compared between the groups. Results. Total protein and albumin concentration was highest in the group of dentulous patients (DP) and significantly different in PE groups (p<0.0001). A significant difference (p<0.011) was observed in the gamma globulin fraction between PD versus PE an...

Objective: The purpose of this study was to determine the effects of coffee consumption on salivary cortisol (sCort) and alpha amylase (sAA) in young adults. Materials and methods: Sixty healthy university students, habitual coffee consumers, participated in this descriptive observational study. Participants were divided into three groups: G1 low consumption (≤ 2 cups of coffee per day, n= 20), G2 moderate consumption (2-5 cups of coffee per day, n = 20), and G3 high consumption (>5 cups of coffee per day, n = 20). Saliva self-collection was in the morning (6:30-7:30 AM) and at night (08:00-09:00 PM). sCort was analyzed using chemiluminescence and sAA activity by kinetic method. Statistical analysis of the data was performed using Student's t-test and analysis of variance. Results: The sample consisted of 30 women and 30 men, aged between 20 and 35 years. In all groups, sCort values...

Salivary cortisol secretion (Corts) is an individual adaptation reflex to internal / external stressors, which involves several biological and social factors. The aim of this study was to perform a review on variations in Corts concentrations in relation to biological differences of sex and gender socialization in the different stages of human development. MEDLINE / PubMed and Google Scholar were used to search for scientific evidence. 20 original English-language articles published from 2010-2020 were selected, including clinical trials and observational studies. The relationship between Corts and gender was historically discussed considering evolutionary and biological aspects. However, it cannot be explained as a cause-effect view and depends on unique sociocultural factors, which in sensitive periods of human development alter the hypothalamic-pituitary-adrenal axis and condition cop...
