INTRODUCTION In teeth with irreversible pulpitis, successful local anesthesia is hard to achieve irrespective of the amount of local anesthesia and technique used. Such cases can be managed by concoction of pre-medications like anxiolytics, analgesics and effective local anesthesia. This double-blind, placebo-controlled study was planned to evaluate the effect of oral administration of alprazol...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
PULPECTOMY – Treatment Considerations Anesthesia It is essential to eliminate any sensation from the tooth being treated prior to endodontic therapy. While it is true that some necrotic teeth can be treated without anesthesia, placement of rubber dam clamps and instrumentation beyond the apex (patency filing) normally make the use of local anesthetic desirable. This is typically achieved throug...
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
اکسیدهای آهن ترکیبی شیمیایی از آهن و اکسیژن می باشند. بطور کلی 16 نوع ترکیب شناخته شده از اکسیدها و هیدروکسیدهای آن وجود دارد. در میان این اکسیدها، آهن 3 اکسید(fe2o3) بسیار مورد توجه است. این اکسید خود از چهار فاز متفاوت آلفا، بتا، گاما و اپسیلون با ویژگیهای منحصر به فرد تشکیل شده است. فاز گامای این اکسید (?- fe2o3)، مگهمایت نام دارد که ساختاری کریستالی و ایزومتریک داشته و فری مغناطیس است. این ...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
