introduction: the aim of this in vitro study was to evaluate the correlation between accuracy of root zx electronic foramen locator and root canal curvature. methods and materials: one hundred and ten extracted mandibular molars were selected. access cavity was prepared and coronal enlargement of mesiobuccal canal was performed. a #10 flexofile was inserted into the mesiobuccal canal, and a rad...

this case report describes treatment of a necrotic immature permanent mandibular first molar with pulpal necrosis in 9-year old female with spondyloepiphyseal dysplasia. the coronal half of the root canal was debrided with a file #30 to remove necrotic tissue, and irrigated with chlorhexidine 0.12%. bleeding was evoked to form an intracanal blood clot; the wound was then dressed with calcium hy...

A 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. He finally was diagnosed as having Twiddler's syndrome. The patient had a pulse rate of 36/min and cannon waves in the neck veins. Chest radiography showed a dislodged pacing lead completely wrapped around the pulse...

The study attempts to evaluate the existing status of Veterinary College Libraries in India by applying the prevailing standards of the Academic Veterinary Medical Library, USA have been applied to the results of this study for inference and discussion, as no such standards are available in Indian context from the perspective of Veterinary College Libraries especially from Veterinary Council of...

he Supreme Court is the highest court of India. It is at the apex of the Indian judicial system. In the previous two lessons, you have learnt that the Union legislature, which is known as Parliament, makes laws for the whole country in respect of the Union and the Concurrent Lists and the executive comprising the President, Council of Ministers and bureaucracy enforces them. Judiciary, the thir...

Using simultaneous high spatial (1.3 arc sec) and temporal (5 and 10 s) resolution H-alpha observations from the 15 cm Solar Tower Telescope at ARIES, we study the oscillations in the relative intensity to explore the possibility of sausage oscillations in the chromospheric cool postflare loop. We use standard wavelet tool, and find the oscillation period of ≈ 587 s near the loop apex, and ≈ 34...

3 Let S be a set of n points in the plane and let R be a set of n pairwise non-crossing rays, 4 each with an apex at a different point of S. Two sets of non-crossing rays R1 and R2 are 5 considered to be different if the cyclic permutations they induce at infinity are different. 6 In this paper, we study the number r(S) of different configurations of non-crossing rays 7 that can be obtained fro...
