The aim of the present study was to prospectively assess the frequency of teeth in which the Reciproc instruments were able to reach the full working length (WL). This case series study enrolled 277 consecutive teeth requiring primary endodontic treatment performed with the Reciproc system (VDW) without a previous glide path by 3 experienced endodontists. Instruments R25, R40 or R50 were select...

Raisins are popular snacks with a favourable nutrient profile, being high in dietary fibre, polyphenols and a number of vitamins and minerals, in addition to being rich in fructose. In light of evidence demonstrating improvements in glycaemic control with moderate fructose intake and low-glycaemic index (GI) fruits, our aim was to determine the GI, insulin index (II) and postprandial responses ...

Abstract This study compared estimates of gale-force wind radii (R30 or R34) and storm-force (R50) tropical cyclones (TC) by three agencies—the Korea Meteorological Administration (KMA), the Regional Specialized Center (RSMC) Tokyo, Joint Typhoon Warning (JTWC)—in western North Pacific during 2015–2018 investigated characteristics these estimates. The results showed that KMA’s R30 R50 were smal...

Aim: To compare the efficacy of various instrumentation techniques for removing obturating material from root canals using Cone Bean Computed Tomography (CBCT). Materials and Methods: Thirty extracted human premolar teeth, each with a single canal were selected. The root canals were prepared upto F4 ProTaper file and obturated with corresponding gutta percha cone. Teeth were divided into three ...

The objective of the present study was to assess the effectiveness of reciprocating instrumentation in disinfecting oval-shaped root canals infected with Enterococcus faecalis. Forty-five human lower premolars were infected with a culture of E. faecalis (ATCC 29212) for 28 days. Five other teeth that were neither contaminated nor instrumented were used as controls. The 45 specimens were divided...

A protocol is prescribed for clinical reference dosimetry of external beam radiation therapy using photon beams with nominal energies between 60Co and 50 MV and electron beams with nominal energies between 4 and 50 MeV. The protocol was written by Task Group 51 (TG-51) of the Radiation Therapy Committee of the American Association of Physicists in Medicine (AAPM) and has been formally approved ...

Using a statistically representative sample of 911 central galaxies (CENs) from the SDSS DR4 Group Catalogue, we study how the structure (shape and size) of the first rank (by stellar mass) group and cluster members depends on (1) galaxy stellar mass (Mstar), (2) the global environment defined by the dark matter halo mass (Mhalo) of the host group, and (3) the local environment defined by their...
