An Audit of the Technical Quality and Iatrogenic Errors of Root Canal Treatment by Undergraduate Dental Students at the University of Sharjah.

Objectives:  The aim of this study was to determine the technical quality of root canal fillings and the presence of iatrogenic errors in the cases treated by undergraduate dental students using radiographic images.

Materials And Methods:  This study included 480 root-filled teeth, which were evaluated using intraoral periapical radiographic images. The technical quality of obturation was assessed by observing the length, density, and taperness of the root filling.

A novel therapeutic drug (copper nicotinic acid complex) for non-alcoholic fatty liver.

Background: Fatty liver is the accumulation of fat in liver cells, which leads to disruption of the normal liver structure and function.

Methods: A non-alcoholic fatty liver rat model received copper (Cu) (I)-nicotinate complex [CuCl(HNA)2] for 4 weeks.

Results: Clinical signs and histopathological examinations showed obvious improvements in rats that received Cu complex who were continuously on an (HCFF) diet than those returned to standard diet with Cu complex.
