INTRODUCTION Root canal anatomy and canal preparation instruments affect the outcome of endodontic treatment. The purpose of this study was to determine the root surface strain (SS) generated and the extent of canal center transportation during canal shaping using 3 different nickel-titanium instruments. METHODS Simulated root canals in resin blocks (n = 10 per group) were prepared using adap...
A major anatomical variant of the two-rooted mandibular first molar is a tooth with an additional distolingual third root: The radix entomolaris (RE). It is essential to anticipate and find all roots and canals during root canal treatment. Proper angulations and interpretation of radiographs help to identify pulp chamber and root anatomy. If present, an awareness and understanding of this unusu...
Finding the root cause of power-based side-channel leakage becomes harder when multiple layers design abstraction are involved. While originates in processor hardware, dangerous consequences may only become apparent cryptographic software that runs on processor. This contribution presents RootCanal, a methodology to explain origin program terms underlying micro-architecture and system architect...
Background: Knowledge about the anatomy of root canals is an important facror in the prognosis of root canal therapy .The purpose of this study is to derermine the root canal anatomy in mandibalar anterior reeth and premolars by clear and dye peneration method. Materials and methods:In this study, 350 human mandibular anterior teeth and mandibular and maxillary premolars(from e...
the aim of ideal canal preparation is to prevent iatrogenic aberrations such as transportation. the aim of this study was to evaluate the root canal transportation by reciproc file with and without glide path.thirty acrylic-resin blocks with a curvature of 60° and size#10 (2% taper) were assigned into two groups (n= 15). in group 1, the glide path was performed using stainless steel k-files siz...
introduction: the purpose of this in-vitro study was to compare shaping ability of niti rotary mtwo and flexmaster with stainless steel hand k-flexofile in curved root canals of extracted teeth. materials and methods: mesiobuccal canals of 45 mandibular molar teeth were balanced into three groups of 15 each, with respect to the schneider angle, canal access angle, height, dis-tance and radius o...
AIM The aim of this study was to evaluate the accuracy of the results of cone beam computed tomography (CBCT) examinations, confirm the presence or absence of the second mesiobuccal (MB2) root canal in maxillary first and second molars, estimate the distance between the root canal orifices, observe the root types based on Vertucci classification system, and make comparisons between CBCT and per...
accurate diagnosis of the root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful treatment. this report describes a case of maxillary second premolar with two roots and three root canals (two mesial and distal palatal canals). the case report underlines the importance of complete knowledge about root canal morph...
