sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
Abstract Background & Aim : This study was aimed to compare the instrumentation time and the amount of debris extruded apically during root canal preparation using hand files ,Mtwo rotary system and endodontic handpiece in primary molar teeth. Method & Material : In this experimental study, sixty roots of primary molars of human teeth were assigned to three groups (for each group, n=20). The...
introduction: one of the most common complications of root canal treatment is postoperative pain. the aim of the present clinical trial was to compare the severity of postoperative pain after root canal preparation with race rotary system and hand k-flexofile. methods and materials: a total of 96 mandibular first and second molars were divided into two groups ( n =48) based on root canal prepar...
Background: Congenital scoliosis is a developmental disorder defined as a lateral curvature of the spine. Its progressive trend and complications, such as cosmetic problems, pain and pulmonary symptoms, have put scoliosis as an important skeletal deformity that should be corrected. One of the currently accepted methods of treatment is posterior spinal fusion (PSF) that may be performed with or ...
objectives : cleaning and shaping of the root canal system is an important step in endodontic therapy. new instruments incorporate new preparation techniques that can improve the efficacy of cleaning and shaping. the aim of this study was to compare the efficacy of mtwo and race rotary file systems in straightening the canal curvature using only one file or the conventional method. materials an...
statement of problem: various factors are involved in causing inflammation following root canal treatment. controlling these factors may relieve the related pain. one of these factors is extrusion of debris beyond the apex. although debris extrusion happens in all instrumentation techniques, researchers have declared that in coronal flaring technique, there is minimum debris extrusion. purpose:...
conclusions it was concluded that ihlq might be a practical and useful tool for investigating hl for persian language speakers around the world. since hl is dynamic and its instruments should be regularly revised, further studies are recommended to assess hl with application of ihlq to detect its potential imperfections. results internal consistency and test-retest reliability (icc) of the fact...
Background: Oxford medial unicompartmental knee replacement (UKR) is indicated in patients with anteromedialosteoarthritis (AMOA) of the knee. Microplasty (MP) instrumentation was introduced in 2012 as an improvement overphase 3 instrumentation. Advantages of this instrumentation include conservative tibial cut, decreased tibial re-cut rateand improved component alignment. We report the results...
introduction: the purpose of this in vitro study was to compare working length (wl) changes after straight-line access (sla) and different coronal flaring (cf) methods. materials and methods: coronal access preparations were made (without sla) in molar teeth to allow access to 120 canal orifices with a hand file. the suitable cusp and root tips were then flattened to facilitate reproducible and...
