Due to a narrow therapeutic range, measurment of theophylline serum levels is highly recommended in patients with a long-term theophylline therapy. In this regard, since blood sampling is an invasive method, exploring alternative methods using other biological fluids in particular saliva samples are targeted. This study was designed to determine any relationship between serum and saliva levels ...

Background:Oral lichen planus (OLP) is considered as a potentially malignant disorder and vascular endothelial growth factor (VEGF) may play a key role in cancer development. The aim of this study was to compare serum and saliva VEGF among patients with OLP, oral squamous cell carcinoma (OSCC) and a healthy control group. Methods:A cross sectional study was pe...

the ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. in the present work, aggregation of the purified hemoglobinin adult (hba) and in fetus or newborn (hbf) in the presence of nitrite ions were studied.hemoglobin aggregation was perform...

background and aims. a carious lesion is the accumulation of numerous episodes of de- and remineralization, rather than a unidirectional demineralization process. tooth destruction can be arrested or reversed by the frequent delivery of fluoride or calcium/phosphorous ions to the tooth surface. the present study compared and evaluated the remineralization potential of sodium fluoride and bioact...

The purpose of our study is to compare the behavior two reprocessed dental alloys (NiCr and CoCr) at different temperatures considering idea that food drinks in oral cavity create various compositions pH levels; novelty investigation temperature effect on corrosion parameters ion release alloys. Electrochemical stability was studied together with morphology, elemental composition ions determina...

objectives: this study aimed to evaluate the effects of saliva contamination on the metallic bracket microleakage bonded with two moisture-tolerant bonding systems. materials and methods:  ninety freshly extracted premolar teeth were randomly divided into six groups of 15 with the following treatments: g1 (control): after acid etching, assure primer and assure adhesive were applied to non-conta...

Background/Aim. Chronic periodontitis is an inflammatory disease. Oxidative stress important factor in progress, hence examining the antioxidative properties of antiseptics, such as chlorhexidine (CHX) and silver ions solution (SSI), a beneficial biomarker estimating recovery tissue impairment during periodontal disease treatment. Methods. This clinical trial was conducted on control group refe...
