PURPOSE Production of reactive oxygen species and reactive nitrogen species is a natural biological event in metabolism. However, the presence of antioxidants can highly reduce the negative effect of free radicals. Thus, the efficiency of antioxidant system in the physiology of exercise is very important. DESIGN Considering the known antioxidant capacity of garlic, the purpose of this study w...

BACKGROUND Oral lichen planus (OLP) is a chronic and inflammation mucosal disease. Reactive Oxygen Species (ROS) and oxidative stress damage might be the cause. Malondialdehyd (MDA), one parameter of lipid peroxidation is appropriate for DNA damage in OLP disease. OBJECTIVE To evaluate antioxidants and oxidative stress parameters in patients with oral lichen planus (OLP) diseases and healthy ...

BACKGROUND The objectives of this study were to assess the total antioxidant levels, dental development, and oral health status in childhood obesity. MATERIALS AND METHODS A total of 120 children aged 6-12 years consisting of both genders from different school along Coastal Karnataka, India were part of the study and were categorized into obese/overweight, and normal children based on body ma...

OBJECTIVES High doses of chemotherapy generate DNA damage in patients undergoing bone marrow transplantation (BMT), due to the production of reactive oxygen species (ROS). In order to evaluate the local defensive effectiveness of the patient undergoing BMT, the concentrations of the antioxidants superoxide dismutase (SOD) and uric acid (UA) were measured in saliva. STUDY DESIGN Basal saliva s...

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...

Acute phase proteins enhance antioxidant defenses; they are involved in the activation of complement components, opsonization and increase in platelet aggregation as well as inhibition of the respiratory burst in the course of inflammation. Malnutrition plays an important role in the course of response of acute phase proteins. The role of nutrients as antioxidants or as key components of antiox...

OBJECTIVES Temporomandibular dysfunction (TMD) is a group of disorders in the facial region and temporomandibular joint (TMJ). Biomarkers are assumed to play a role in pain and early detection of destruction. The aim of this study was to compare the saliva and serum antioxidant levels in patients with TMD and healthy subjects. MATERIALS AND METHODS This case-control study was conducted on 28 ...

OBJECTIVE: Oral manifestations in diabetic patients can have different causes. Possibly, one of these causes is salivary glucose. The aim of this study was to evaluate salivary glucose concentrations in patients with Type II diabetes mellitus (DM) and their association with oral and dental manifestations and compare them with normal adults. MATERIALS AND METHODS: In this analytical study, 128 p...

Background: This study was performed to evaluate the effects of probiotics on salivary flow rate and pH in children with Acute Lymphocytic Leukemia (ALL) during chemotherapy.   Methods: A randomized clinical trial was conducted on 11 children with ALL on induction and consolidation phases of chemotherapy. At the beginning, clinical examination of the oral mucosa and dental hygiene and intervie...
