background: there is abundance of literature delving into whether periodontal infection contributes to changes in serum lipid profi les. whole saliva is an important physiologic fl uid that contains a highly complex mixture of substances. research on salivary lipid profi les and chronic periodontitis remains unexplored and limited. this study was designed with an aim to investigate the associat...

Introduction and Aim: Cention N is an “alkasite” restorative material which utilizes alkaline filler capable of releasing acid-neutralizing ions. These ions can be helpful in buffering the pH saliva, thus preventing carious activity. Hence this study was undertaken to investigate action Cention-N material. Materials methods: Solutions distilled water with values adjusted approximately 5.5, 6.5 ...

background: oral lichen planus (olp) has been classified as a pre-malignant condition. matrix metalloproteinase-13 (mmp-13) or collagenase-3 may play a key role in cancer development. the aim of this study was to compare serum and saliva mmp-13 between patients with oral lichen planus (olp) and oral squamous cell carcinoma (oscc).   methods : this cross sectional study was performed on 30 patie...

  In this study the effect of propylthiouracil-induced hypothyroidism on rat submandibular salivary gland function and the level of copper and zinc trace elements in serum and saliva were determined. Propylthiouracil (PTU) was administered to rats for 1, 2 and 3 weeks in three different groups to induce hypothyroidism. Pilocarpine was administered under anesthesia and pure samples of saliva wer...

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...

statement of problem: following the increasing use of composites in restoring anterior and posterior teeth, problems due to its technique sensitivity have become a major concern. one of these problems is the possibility of contamination of dentin with saliva, blood and/or gingival fluid in different stages of bonding procedure, even with application of different methods of isolation. however, b...

background: the aim of the present study was to induce salivation in haemaphysalis longicornis to increase saliva production and to characterize the collection of proteins present in the collected saliva using on-chip-electrophoresis. methods: saliva of adult female engorged h. longicornis was collected by treatment with 0.2% dopamine hydrochlo­ride. all protein samples were characterized by sd...

the purpose of this study was to determine the effects of official soccer competition on saliva cortisol, testosterone and immunoglobulin a in male players. for this purpose, 14 fixed players (age: 28.24±4.3 years) were equally selected from two opponent teams in 2009 elimination cup. saliva samples at the rest and immediately after the first half time, before and after the second half time wer...

Background: Early Childhood Caries (ECC) is one of the most common chronic child-hood diseases. In spite of the global decrease in dental caries in the past decades, ECC has become a significant problem in many developing countries and also in a few indus-trialized nations. Saliva as a host factor can play an important role in the process of den-tal caries. Objective: The aim of this study was ...

Introduction: Since pharmaceutical syrups are widely taken by children in Iran, drop of pH in oral cavity and dental decay resulted from the syrups are of high importance. This research aims to study buffering properties of saliva when in contact with some of vitamin syrups available in pharmaceutical market of Iran. Methods: In the present study, 1 milliliter (ml) of 6 samples of vitamin sy...
