The stress response of salivary alpha-amylase (sAA) has been suggested as an index for sympathetic nervous system activation. However, concurrent inhibition of the parasympathetic nervous system is discussed as a confounder due to suppression of saliva flow rate. Here we set out to test the influence of stress-induced changes in flow rate on sAA secretion. Twenty-six subjects underwent the Trie...

To investigate the relationship between dental caries and the salivary flow rate, secretory immunoglobulin A (sIgA) or other components in children, nonstimulated whole saliva was collected and teeth status was examined in 138 boys and 134 girls aged 11-12 years. The subjects were apparently healthy. The mean salivary flow rate was faster in boys than in girls (0.29 vs 0.18 ml/min, p < 0.001). ...

Background and aim: Hyposalivation is one of the most common complications during menopause, which affects the quality of life. The aim of the present study was to assess the correlation between menopause and salivary flow rate. Materials and methods: This historical-cohort study was conducted on 80 healthy women. Forty postmenopausal women were placed in the case group, while 40 premenopaus...

The aim of this study was to evaluate the oral sequelae of radiotherapy in patients treated between 1999 and 2003 for head and neck tumors. One-hundred patients (24 women, 76 men) ranging in age from 30 to 83 years (mean 59.2 years) were examined. Time since radiotherapy ranged from 1 to 72 months (mean 28 months). The total mean radiation dose received by the patients was 5,955 cGy. The evalua...

AIM The aim of this study was to investigate the dental status of alcoholics; to evaluate the relationship of unstimulated and stimulated saliva pH on their decayed/missing/filled teeth (DMFT); and to evaluate the relationship of unstimulated and stimulated salivary flow rate on their DMFT. METHOD A cross-sectional study was conducted in patients treated for alcohol dependency (n = 70; mean a...

The evaluation of the salivary flow rate is important in several situations of dental practice. However, weighing the collected salivary volume it is not a practical method in public health services. This work evaluated the use of hypodermic graduated syringes as a simpler alternative method to measure the salivary flow rate. Saliva samples were obtained from 50 individuals (31 females and 19 m...

  In this study the effect of propylthiouracil-induced hypothyroidism on rat submandibular salivary gland function and the level of copper and zinc trace elements in serum and saliva were determined. Propylthiouracil (PTU) was administered to rats for 1, 2 and 3 weeks in three different groups to induce hypothyroidism. Pilocarpine was administered under anesthesia and pure samples of saliva wer...

PURPOSE The aim of the study was to examine salivary flow rate, DMF index, lysozyme concentration and its output in two groups of rheumatoid patients and to compare the results with those of healthy controls. MATERIAL/METHODS Rheumatoid arthritis (RA) patients were divided into two study groups: with reduced salivary flow rate ≤0.15 ml/min (RA HS, hyposalivation) and with normal salivary secr...
