OBJECTIVE The aim of this study was to compare the fracture strength of roots instrumented with three different single file rotary systems in curved mesial root canals of maxillary molars. MATERIALS AND METHODS Curvatures of 25°-35° on mesial roots of 60 maxillary molar teeth were sectioned below the cementoenamel junction to obtain roots 11 mm in length. The roots were balanced with respect ...

Induced hairy roots by Agrobacterium rhizogenes are suitable organs for the production of secondary metabolites, due to the stability and high production of roots without phyhormones in a short time. Fenugreek (Trigonella foenum– graecum L.) is one of the most important medicinal plants with valuable medicinal compounds. For optimizing the hairy root induction of T. foenum-graecum L., six strai...

In this paper, we proposed a three-point iterative method for finding the simple roots of non- linear equations via mid-point and interpolation approach. The method requires one evaluation of the derivative and three(3) functions evaluation with efficiency index of 81/4 ≈ 1.682. Numerical results reported here, between the proposed method with some other existing methods shows that our method i...
