Cone beam CT, usually used in dental area, could easily obtain 3-dimensional images using cone beam shaped ionized radiation. Cone beam CT is very useful for direct percutaneous sac injection (DPSI) which needs very precise measurement to avoid puncture of inferior vena cava or vessel around sac or stent graft. Here we describe two cases of DPSI using cone beam CT. In case 1, a 79-year-old male...

O n February 16, the Joint Commission (TJC) issued newly approved requirements for diagnostic imaging services for hospitals, critical access hospitals, and ambulatory care organizations and released a prepublication version of the standard revisions. These revisions, most of which will become effective on September 1, 2016, specify the minimum qualifications needed by technologists to perform ...

BACKGROUND A fundamental pre-requisite for the clinical success in dental implant surgery is the fast and stable implant osseointegration. The press-fit phenomenon occurring at implant insertion induces biomechanical effects in the bone tissues, which ensure implant primary stability. In the field of dental surgery, the understanding of the key factors governing the osseointegration process sti...

BACKGROUND In equine practice, teeth corrections by means of motorized grinding systems are standard procedure. The heat resulting from that treatment may cause irreparable damage to the dental pulp. It has been shown that a 5.5°C temperature rise may cause severe destruction in pulp cells. Hence, the capability to continuously form secondary dentine is lost, and may lead, due to equine-typical...

REASONS FOR PERFORMING STUDY There is limited knowledge on the thickness of subocclusal secondary dentine in equine cheek teeth (CT). HYPOTHESES Subocclusal secondary dentine is of consistent thickness above different pulp horns in individual horses and its thickness increases with age. METHODS 408 permanent CT were extracted post mortem from 17 horses aged 4-30 years, with no history of de...
