Cloud computing offers the opportunity to improve efficiency with cloud providers offering consumers the ability to automatically scale their applications to meet exact demands. However, “auto-scaling” is usually provided to consumers in the form of metric threshold rules which are not capable of determining whether a scaling alert is issued due to an actual change in the demand of the applicat...

Mandibular premolars usually have a single root and canal. Complex root canal system with atypical variations is a common finding among them. Failure to identify such a one can affect the prognosis of endodontic treatment. Apart from knowledge and sophisticated instruments, a good clinical expertise is required in identifying, tracing and treating such a root canal system. This case report is o...

Benign paroxysmal positional vertigo of the superior semicircular canal is a rare form of BPPV. It accounts for 1% to 3% of cases. The characteristic nystagmus is positional, down-beating, with a torsional component elicited by the Dix-Hallpike maneuver. Symptoms of superior semicircular canal BPPV often resolve spontaneously; however, it can be refractory to repositioning maneuvers. Surgical m...

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...

Posterior canal benign paroxysmal positional vertigo (BPPV) is the most frequent form of BPPV. It is characterized by a paroxysmal positioning nystagmus evoked through Dix-Hallpike and Semont positioning tests. Anterior canal BPPV (AC) is more rare than posterior canal BPPV; it presents a prevalent down beating positioning nystagmus, with a torsional component clockwise for the left canal, coun...

Root canal retreatment is often the preferred method of treating a tooth in which root canal treatment has failed. Part one of this two-part article discusses reasons for failure of root canal treatment, case assessment and treatment planning. Part two describes some of the practical techniques that are available to the practitioner and the rationale for root canal retreatment. Dent Update 2004...

The use of cavitation for improving biofilm cleaning is great interest. There no system at present that removes the from medical implants effectively and specifically dental implants. Cavitation generated by a vibrating ultrasonic scaler tip can clean biomaterials such as However, process must be significantly accelerated clinical applications. In this study we investigated whether could increa...

During the treatment process for benign paroxysmal positional vertigo (BPPV) using canalith repositioning procedure, otolith can inadvertently enter semicircular canal instead of utricle. Canal conversion refers to situation where enters a different canal, while reentry occurs when returns same canal. The occurrence complicate accurate diagnosis and BPPV, potentially leading misdiagnosis unsucc...

Introduction: To achieve a successful endodontic treatment, the clinician has to identify the different canal configurations.mandibular premolars have the wide variety of root canal morphology and they are known as the most difficult teeth to treat in endodontics.CBCT  provides a non-invasive 3D confirmatory diagnosis as a complement to conventional radiography.The aim of this study was to...
