OBJECTIVE This study aims at determining pH and Flow Rate (FR) of Unstimulated Whole Saliva (UWS) in a sample of 120 ♀ (60 menopausal women and 60 healthy fertile women with similar mean age); detecting the DMFT index (Decayed, Missing, Filled Teeth index) and evaluating any correlations between pH, FR, age and DMFT. METHODS Concerning the day before sample collection, patients were advised to keep a relaxed attitude and not to practice sports. They were also told to not eat or drink during the hour preceding sampling procedures. Saliva was collected via "spitting" method. Each sampling session started at 11:00 a.m., lasted for 5 minutes and used a pre-weighed, dry, deionized and sterile test tube. The procedure took place under controlled environmental temperature and humidity conditions (means 23.27°C; 60.08%). FR was evaluated via weighing technique and pH was measured with a portable pH-meter. RESULTS There was a minimal but significant pH difference (0.11; p<0.05) between menopausal women (6.75 ± 0.34) and fertile women (6.86 ± 0.24); and a FR difference (0.19; p<0.0001) between menopausal women (0.29 ± 0.17 mL/min) and fertile women (0.48 ± 0.19 mL/min). Correlation (R2) between pH and age was 0.0135 for fertile women and 0.0055 for menopausal women; while the correlation between FR and age was 0.0673 for fertile women and 0.139 for menopausal women. Mean DMFT was 11.93 ± 7.14 in menopausal women and 12.23 ± 6.37 in fertile women. CONCLUSIONS We observed a minimal decrease in pH and a decrease in FR in menopausal women. Further studies will be needed to investigate the possible role of other environmental and individual variables in the determination of such values.
