background: the possibility of impaired antioxidant status and so increased oxidative damage in periodontal disease is being conjectured. the present randomized controlled study was carried out with the objective of analyzing the activity of superoxide dismutase enzyme and thiol antioxidants in gingival crevicular fluid (gcf) and saliva as indicators of response to periodontal therapy. material...

Background: The aim of this study was to investigate the effects of Melissa officinalis tea on the total antioxidant capacity of saliva among smokers. Methods: 24 smokers were selected by convenience sampling. Demographic information and duration of smoking were recorded at the beginning of study. Two cups of Melissa officinalis tea were given to the participants with specific instruction for ...

introduction: tobacco smoke is involved in the pathogenesis of several diseases in different body systems. saliva is the first body fluid that confront inhaled cigarette smoke which is injurious to the oral cavity and is associated with several oral diseases and cancer. the aim of our study was to evaluate the influence of smoking on the activity of alpha-amylase in the saliva of healthy smoker...

introduction sialolithiasis is the most common disease of salivary glands. sialography is particularly important for the assessment of the outflow tract and in diagnosing obstructive salivary gland lesions including calculi. case presentation we report on a 38-year-old female with sialolithiasis whom had wharton’s duct perforation, complicating the sialography. she was treated conservatively wi...

The aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. The rats were treated with thymol at dose of 50 mg/Kg before exposure to radiation at dose 15Gy. Salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...

A multicomponent evaluation of the oxidative consumption of salivary biomolecules by a hydrogen peroxide (H2O2)containing tooth-whitening formulation has been performed using high-resolution proton (H) nuclear magnetic resonance (NMR) spectroscopy. Unstimulated human saliva samples (n = 10) were treated with aliquots of supernatants derived from 1) the H2O2-containing whitening gel, 2) the corr...

Intracellular Ca2+ mobilization is closely linked with the initiation of salivary secretion in parotid acinar cells. Reactive oxygen species (ROS) are known to be related to a variety of oxidative stress-induced cellular disorders and believed to be involved in salivary impairments. In this study, we investigated the underlying mechanism of hydrogen peroxide (H2O2) on cytosolic Ca2+ accumulatio...

OBJECTIVE The aim of the present study was to compare between two antioxidant treatments in prevention of fenitrothion induced toxicity on rat parotid salivary gland. DESIGN Forty adult male Wistar rats with an average weight of 120-150 g were randomised into 4 groups, control (group I), fenitrothion administration (group II), fenitrothion administration 1h after green tea extract or Nigella ...
