Cementum and dentin repair following root damage caused by the insertion of self-tapping and self-drilling miniscrews.

Objective: The aim of this study was to evaluate the histological responses of cementum, root dentin, and pulp following intentional root injuries caused via self-tapping and self-drilling miniscrews.

Materials And Methods: Fourteen patients (with a mean age of 15.7 years and age range of 14-18 years) who were scheduled for the extraction of all four first premolars as part of their orthodontic treatment plan participated in this study.

Microhardness of demineralized enamel following home bleaching and laser-assisted in office bleaching.

Background: There is little data regarding the effect of tooth whitening on microhardness of white spot lesions. This study was conducted to investigate the effect of home-bleaching and laser-assisted in-office bleaching on microhardness of demineralized enamel.

Material And Methods: Forty bovine incisors were selected and immersed in a demineralizing solution for 12 weeks to induce white spot lesions.

The effects of wet cupping on serum high-sensitivity C-reactive protein and heat shock protein 27 antibody titers in patients with metabolic syndrome.

Introduction: It has previously been reported that increased level of serum heat shock proteins (Hsps) antibody in patients with metabolic syndrome. It is possible that the expression of Hsp and inflammatory markers can be affected by cupping and traditional Chinese medicine. There is a little data investigating the effects of cupping on markers of inflammation and Hsp proteins, hence, the objective of this study was evaluation of the effects of wet cupping on serum high-sensitivity C-reactive protein (hs-CRP) and Hsp27 antibody titers in patients with metabolic syndrome.

Simple method for reliable predicting flash points of unsaturated hydrocarbons.

This work introduces a simple method for prediction of the flash point of different classes of unsaturated hydrocarbons including alkenes, alkynes and aromatics. Elemental composition is used as a core function that can be revised for some compounds by a correcting function. The predicted flash points for a data set of 173 unsaturated hydrocarbons are in good agreement with the measured values such that the root mean square (rms) error is 9 K.
