Safevi Ülkesinin İngiliz Konukları (İngiliz Tacirlerin İran Seyahatleri, 1562-1581)

ÖZER KÜPELİ

English merchants participated in overseas trade in the 16th century and gradually increased their roles in this trade. Joint-stock companies, which were sponsored by the Kingdom of England, were the greatest factor in this increase. One of those joint-stock companies was founded in Russia in 1553 and took control of the Russian trade in a short time. Meantime Anthony Jenkinson was appointed as captain-general of the Muscovy Company in 1557. His initial step was to make an expedition of discovery to Caspian Sea and beyond. He noticed commercial potential of Persia during his expedition. Thereu ...Daha fazlası

Mandibular anterior bony support and incisor crowding: Is there a relationship?

İLKNUR VELİ

INTRODUCTION: The aim of this study was to test the null hypothesis that increased irregularity of the mandibular incisors is associated with a reduction in the alveolar support on cone-beam computed tomographic sections. METHODS: From a sample of 1100 digital volumetric tomographs, 125 tomographs of subjects with Class I malocclusion (mean age, 21.6 ± 4.8 years) were selected for this study. An irregularity index was used to categorize these tomographs as having mild, moderate, or severe crowding. All tomographs were taken by using an iCAT (Imaging Sciences International, Hatfield, Pa) ima ...Daha fazlası

Effects of demineralizaton-inhibition procedures on the bond strength of brackets bonded to demineralized enamel surface

TANCAN UYSAL

Objective: To study and compare the effects of different demineralizationinhibition methods on the shear bond strength (SBS) and fracture mode of an adhesive used to bond orthodontic brackets to demineralized enamel surfaces. Methods: Eighty freshly extracted, human maxillary premolars were divided into 4 equal groups and demineralized over the course of 21 days. Brackets were bonded to the demineralized enamel of teeth in Group 1. In Group 2, bonding was performed following resin infi ltration (ICON®, DMG, Hamburg, Germany). Before bonding, pre-treatment with acidulated phosphate fluor ...Daha fazlası

Resonance frequency analysis of orthodontic miniscrews subjected to light-emitting diode photobiomodulation therapy

TANCAN UYSAL

The aim of this prospective experimental study was to evaluate the effect of light-emitting diode (LED) photobiomodulation therapy (LPT) on the stability of immediately loaded miniscrews under different force levels, as assessed by resonance frequency analysis (RFA). Sixty titanium orthodontic miniscrews with a length of 8 mm and a diameter of 1.4 mm were implanted into cortical bone by closed flap technique in each proximal tibia of 15 New Zealand white adult male rabbits (n = 30). The animals were randomly divided into irradiated and control groups under different force levels (0, 150, and 3 ...Daha fazlası
