background and aims. the aim of this study was to establish a relationship between salivary glucose levels and candida carriage rate in type 2 diabetes mellitus patients and assess the growth characteristics and acid production of candida in glucose-supplemented saliva. materials and methods. a total of 90 subjects, 30 with controlled type 2 diabetes, 30 with uncontrolled type 2 diabetes and 30...

OBJECTIVES The present study was designed to evaluate the changes in saliva properties and oral microbial flora in patients undergoing fixed orthodontic treatment. MATERIALS AND METHODS Two important saliva properties namely the salivary flow rate and pH as well as oral microbial flora were assessed in 30 orthodontic patients before starting fixed orthodontic treatment and after six, 12 and 1...

The aim of this study was to quantify the buffer attributes (value, power, range and optimum) of two model systems for whole human resting saliva, the purified proteins from whole human resting saliva and single proteins. Two model systems, the first containing amyloglucosidase and lysozyme, and the second containing amyloglucosidase and alpha-amylase, were shown to provide, in combination with...

The aim of this study was to investigate the relationship between several parameters of saliva and erosive wear in adolescents. (Un-)stimulated saliva was collected from 88 adolescents with erosion and 49 controls (age 16 ± 1 years). Flow rate, pH and buffer capacity were determined immediately. Total protein content, carbonic anhydrase VI, amylase, albumin, calcium, phosphate, urea, sodium, ch...

AbstractBackground: Saliva is a biological fluid that has multiple protective functions. These functions can beattained only if the saliva keeps certain physo-chemical properties such as pH.Methods: The main purpose of the current study was to compare the salivary pH among khat chewers and<b...

In order to know the relationship between inorganic ion composition of saliva and dental caries prevalence, saliva from children was studied. The saliva samples were collected from 30 subjects aged 3 to 18 years. Each inorganic ion concentration and pH of saliva was measured and their relationship to dental caries was studied. The results were as follows: 1. Significant relationship was noted b...

OBJECTIVE The probiotic strain Lactobacillus rhamnosus GG (LGG) is shown to hamper the presence of mutans streptococci in saliva and may have positive effects on oral health. We investigated the effects of LGG on the cariogenic potential and microbial composition of saliva-derived microcosms. DESIGN Single and dual species biofilms of LGG and Streptococcus mutans, and saliva-derived microcosm...

OBJECTIVE To determine the correlation between pH and bicarbonate of soda in blood and saliva in child and adolescent patients during the administration of 3 g/m2 of methotrexate. METHOD A controlled clinical test was performed on 23 patients diagnosed with Acute Lymphoblastic Leukemia. Ages ranged from 4 to 18. The Spearman Correlation Coefficient was used to interpret the data. RESULTS No...

A model of synthetic saliva (SALMO, SALiva MOdel) is proposed for its use as standard medium in in vitro equilibrium and speciation studies of real saliva. The concentrations come out from the literature analysis of the composition of both real saliva and synthetic saliva. The chief interactions of main inorganic components of saliva, as well as urea and amino acids, are taken into account on t...

OBJECTIVES/HYPOTHESIS To determine salivary pepsin levels as a function of collection time. STUDY DESIGN A prospective, case-control study. METHODS We selected 57 patients with clinical symptoms and signs of laryngopharyngeal reflux who underwent 24-hour multichannel intraluminal impedance-pH (24h MII-pH) monitoring tests, and 12 control subjects without clinical symptoms and signs of laryn...
