Introduction: Cleaning and shaping of the root canal system with an efficient and safe technique are the major goals of root canal treatment. The aim of this study was to compare the conventional root canal preparation technique by hand instruments and Gates Glidden drills with ProTaper Universal Rotary system on the root susceptibility to vertical fracture. Methods: Thirty extracted human man...
The main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. Failure to find and fill a canal contributes toward the failure of endodontic therapy .The root canal anatomy of mandibular first molars is complex. Studies of the morphologic structure of root canal systems hav...
Root system growth and development is highly plastic and is influenced by the surrounding environment. Roots frequently grow in heterogeneous environments that include interactions from neighboring plants and physical impediments in the rhizosphere. To investigate how planting density and physical objects affect root system growth, we grew rice in a transparent gel system in close proximity wit...
background and aims. the knowledge of variations in root canal morphology is critical for a successful endodontic treatment. the purpose of this study was to investigate variations in the root canal system of human mandibular first permanent molars in an iranian population. materials and methods. in this study, 209 mandibular first molar teeth were decalcified, dye-injected, and cleared in orde...
