many materials have been introduced for apexification each having their own advantages and disadvantages. this case report aims to present a new method of apexification using a combination of deproteinized bovine bone mineral (dbbm) and enamel matrix derivative (emd). after irrigating the canal of the maxillary right canine with 2.5 % sodium hypochlorite, a mixture of bio-oss and emd was packed...

external inflammatory root resorption (eir) represents a challenge in endodontic practice. eir commonly occurs after dental trauma that results in periodontal ligament injury, pulp necrosis and subsequent infection.  treatment of eir is based on disinfecting the root canal system through chemomechanical procedures and then filling it with calcium hydroxide or triple antibiotic paste. dental tra...

Stem cells are the pluripotent cells that have the capacity to differentiate into other specialized cells. Recently, many experiments have been conducted to study the potentiality of stem cells in the tissue regeneration. We report two cases treated utilizing stem cells from human exfoliated deciduous teeth (SHED) in the management of periapical lesions in permanent teeth. Two normal human deci...

Objective: To present an anterior thoracoscopy-assisted mini-open approach for minimally invasive resection of neurogenic tumors located at the thoracic apex. Methods: From February 2002 to December 2013, 18 consecutive patients underwent resection of neurogenic tumors located at the thoracic apex using a thoracoscopyassisted mini-open approach at our institution. There were 6 male and 12 femal...

Apex predators are subject to lethal control in many parts of the world to minimize their impacts on human industries and livelihoods. Diverse communities of smaller predators-mesopredators-often remain after apex predator removal. Despite concern that these mesopredators may be 'released' in the absence of the apex predator and exert negative effects on each other and on co-occurring prey, the...

The recently released persistent memory (PM) offers high performance, persistence, and is cheaper than DRAM. This opens up new possibilities for indexes that operate persist data directly on the bus. Recent learned exploit distribution have shown great potential some workloads. However, none support persistence or instant recovery, existing PM-based typically evolve B+-trees without considering...
