The effect of 3 % hydrogen peroxide irrigation on postoperative complications of rhinoplasty: A double-blinded, placebo-controlled Randomized Clinical Trial.

The aim of this study was to evaluate the effect of irrigation with 3% Hydrogen Peroxide solution on early complications of rhinoplasty. Volunteers who had physical status of ASA I were included in the study after informed written consent. This was a randomized, double-blinded, placebo-controlled clinical trial.

The effect of a single 75 mg preoperative dose of pregabalin on postoperative pain in rhinoplasty: A double-blinded, placebo-controlled randomized clinical trial.

The goal of this study was to evaluate the effect of a single preoperative dose of 75 mg of pregabalin on postoperative pain in rhinoplasty. Volunteers with a physical status of ASA I were included in our study after informed written consent. This was a randomized, double-blinded, placebo-controlled clinical trial.

Sleep Architecture and Hypothalamic-Pituitary-Adrenal Activity in Paradoxical and Psychophysiological Insomnia.

Introduction: There are controversial reports about association between sleep and Hypothalamic-Pituitary-Adrenal (HPA) activity. Studies have reported the influence of insomnia on HPA hormones. However, they usually ignored the heterogeneity of insomnia symptoms, so subtypes of the disorder have not been considered in the reports.

The Effect of Gates-Glidden Drills on the Quality of Root Canal Treatment by Pre-Clinical Dental Students.

Aim: This study was conducted to investigate the effect of applying Gates-Glidden (GG) drill by pre-clinical dental students on root canal treatment quality.

Method: A total of 56 first molars consisting of 168 canals were selected in this study. For this purpose, 56 students who had been formerly trained by two methods of root canal preparation were randomly divided into two groups (n = 28).

Decreased Gene Expression of Epstein-Barr Virus-Induced Gene 3 (EBI-3) may Contribute to the Pathogenesis of Rheumatoid Arthritis.

Background: Interleukin-35 (IL-35) is a member of the IL-12 family of heterodimeric cytokines produced by regulatory T (Treg) cells. This immunosuppressive cytokine can prevent exaggerated inflammatory responses like those responsible for the development of rheumatoid arthritis (RA). This study aims to determine the correlation between the gene expression of Epstein-Barr virus-induced gene 3 (EBI-3) and IL-12A (p35) subunits of IL-35 in peripheral blood leukocytes with immunological and clinical parameters in RA patients.

Prevalence of Apical Periodontitis in Different Communities: A Meta-Analysis.

Introduction: The aim of this study was to perform a meta-analysis on the prevalence of apical periodontitis (AP) in different communities to obtain accurate data on its prevalence.

Methods And Materials: The prevalence of AP in different communities based on the number of individuals, teeth and root-filled teeth was searched using electronic databases of ISI Web of Knowledge, PubMed, Scopus and also ProQuest and Springer. The Metaprop meta-analysis was done using the software R version 3.

Enhancement of the Mechanical Properties of Hydroxyapatite/Sulphonated Poly Ether Ether Ketone Treated Layer for Orthopaedic and Dental Implant Application.

The mechanical properties of coated layers are one of the important factors for the long-term success of orthopeadic and dental implants. In this study, the mechanical properties of the porous coated layer were examined via scratch and nanoindentation tests. The effect of compression load on the porous coated layer of sulphonated poly ether ether ketone/Hydroxyapatite was studied to determine whether it changes its mechanical properties.
