BACKGROUND Methamphetamine, a highly addictive sympathomimetic stimulant, is currently widely abused worldwide and has been associated with devastating effects on oral health, resulting in the term "meth mouth". However, "meth mouth" pathology is primarily based on case reports with a lack of systematic clinical evaluation. Therefore, we have conducted a systematic study to investigate (1) the ...

OBJECTIVE To analyze kinematic viscosity and pH of unstimulated whole saliva, evaluate possible variations after sampling, identify any gender differences and detect possible correlations between them. SUBJECTS AND METHODS The sample consisted of sixty-four healthy young adults (37 females and 27 males, mean age 25.2 years). Saliva was collected using the spitting method at 11:00 am. Kinemati...

Background: Dental caries occur due to a dynamic demineralization process that happens when calcium and phosphate ions are dissolved carbohydrates fermented by microorganisms in the mouth, leading decrease saliva pH. Saliva production occurs as response stimuli such tasting chewing food. contains oral cavity bacteria, cervical gingival fluid, leftover food, known whole saliva. Normally, pH rang...

background: chewing sugar-free gums is a convenient way to increase salivary flow. salivary flow increases in response to both gustatory (taste) and mechanical (chewing) stimuli, and chewing gum can provide both of these stimuli. the aim of this study was to compare the effect of five different flavors of sugar-free chewing gum on the salivary flow rate (sfr) and ph. materials and methods: fift...

objective: the purpose of this study was to evaluate the solubility of three luting cements in artificial saliva. materials and methods: twenty disks (10×4 mm) of polycarboxylate, zinc phosphate and glass ionomer cements were prepared according to manufactures’ instructions. after setting, they were desiccated and each ten specimens were immersed in artificial saliva with special ph (3 or 5), c...

The aim of the present comparative study was to compare some salivary characteristics between exclusive waterpipe smokers (EWPS) and non-smokers. 72 males (36 EWPS) were recruited. The volume of stimulated saliva was determined and divided by the duration of saliva collection. The pH was measured directly using a pH meter. The buffering capacity was determined using a quantitative method which ...

In the present study, the growth of a single isolate of Candida albicans on seven saliva-, serum-coated or protein free (uncoated), thermocycled (4-70 degrees C for 1 min, respectively; 0, 1000 and 10 000 times) commercial resilient lining materials was investigated by monitoring pH changes in growth media. The inhibitory effect of the tissue conditioners on fungal growth was observed using thr...

UNLABELLED Several studies have shown how cytostatics may cause hypofunction of salivary glands but failed to elucidate any potentially related side effects. Keeping in mind the sialochemical assistance and the role of saliva on the homeostasis of the stomatognathic system, the aim of this study was to establish potential gland disorders in patients submitted to 5- Fluorouracil (5-Fu) and Leuco...

OBJECTIVE To isolate Helicobacter pylori (HP) from the dental plaque of a selected group of children and to compare the oral and salivary findings of patients with those of a healthy control group. METHODS A total of 70 children aged 5-15 years were included in this study. An intraoral examination was performed for each patient, and dental plaque and saliva specimens were collected for analys...

Immunologic analysis, originally developed for urine, is also effective for saliva. Using fluorescence polarization immunoassay (FPIA), we analyzed saliva directly (without former extraction) for barbiturates, opiates, cannabinoides, amphetamines, and cocaine. By using calibration standards, cut-off limits were established. The presence of benzodiazipines was tested using radioimmunoassay. Subs...
