Streptococcus mutans is important in dental caries. Although the role of cytokines in the pathogenesis of dental caries is not clear, components of S. mutans were found to stimulate production of pro-inflammatory cytokines. We examined the associations of interleukin (IL)-1β, IL-1 receptor antagonist (IL-1ra), and IL-10 with dental caries. Unstimulated whole saliva and blood samples were obtain...

The purpose of this study was to identify and compare the presence of HCMV and EBV-1 in subgingival plaque, unstimulated saliva and peripheral blood of patients with chronic periodontitis. Forty patients diagnosed with chronic periodontitis (mean age, 41.7 years) were recruited. Unstimulated saliva, subgingival plaque and peripheral blood were collected from each patient and the DNA of each sam...

INTRODUCTION AND OBJECTIVE Dental caries is an inflammatory disease with multifactorial etiology. The presented study was conducted to test the hypothesis that the elevation of salivary cytokines - interleukin-6 (IL-6), interleukin-8 (IL-8) and tumour necrosis factor (TNF-a) is changed in dental caries patients. IL-6, IL-8 and TNF-a are particularly relevant to inflammation, one of the very fir...

AIM To determine the concentration of fluoride in saliva and supragingival dental plaque at designated time intervals after consumption of snacks prepared with a standardised amount of fluoridated salt. STUDY DESIGN The investigation had a single blind prospective crossover design. METHODS A group of 11 healthy young adults volunteered to participate after verbal and written information and...

Several studies report that mutans streptococci (MS) are closely associated with caries in humans and that there is a correlation between the number of carious lesions and the levels of MS in the saliva of children and adults. The presence of MS in the saliva of 93 members of six Brazilian families with at least 3 generations was investigated. Samples of whole unstimulated saliva were collected...

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...

Objective: To compare the release of fluoride into unstimulated wholesaliva in vivo after the application of three different 5% NaF varnishes:Enamel Pro, Vanish, and Duraphat.Experimental Methods: Following IRB approval, 15 subjects wererecruited and consented based upon the inclusion/exclusion criteria of thestudy. A four-treatment randomized cross over study design wit...

background: detection of cancer at an early stage is of utmost importance to decrease the morbidity and mortality of the disease. apart from the conventional biopsy, non‑invasive methods like analysis of serum and saliva may provide cost‑effective approach for screening a large population. tumor markers are a major part of secondary prevention and thus, the detection of malignancies. the aim of...

Introduction: The aim of this study was to evaluate thiobarbituric acid reactive substances (TBARS) as lipid peroxidation marker and total antioxidant capacity(TAC) in saliva of smoker and non-smoker men. Materials & Methods: This case-control study was performed on 104 men including smoker (52) and non-smoker (52) men, referred to the Oral Medicine Department in Babol Faculty o...

Previous studies have indicated that there may be a relationship between the salivary fluoride concentrations and dental caries while the emphasis was on dental caries in permanent teeth. The aim of this study was to assess the prevalence of dental caries and its predictors in 3-6 year-old children in Tehran, Iran. The other objective of this investigation was to clarify a relationship between ...
