Purpose The American Academy of Pediatric Dentistry (AAPD) advocates , when indicated, hospitalization and equal access to operating room facilities for oral care of infants, children, adolescents, and persons with special health care needs. The AAPD recognizes that barriers to hospital oral care for patients who require treatment in that setting need to be addressed. Method This policy is an u...

Osseointegration of a titanium implant is still an issue in dental/orthopedic implants durable over time. The good integration of these implants is mainly due to their surface and topography. We obtained an innovative titanium surface by shooting different-in-size particles of Al₂O₃ against the titanium scaffolds which seems to be ideal for bone integration. To corroborate that, we used two dif...

The Integrated Remote Neurosurgery Sys-tem(IRNS) was developed as a test bed to determine how telerobotic capabilities can be safely exploited in the operating room environment. In this report, a microscope is mounted on the robot to provide a high quality bidirectional mentoring system. The mentor can move, focus, and zoom the microscope remotely. This paper will address the issues relating to...

Microscope projection lithography offers an affordable alternative for fast prototyping of 3D polymer microstructures. Here we introduce a 3D mask-less approach operating on a routine epi-fluorescene microscope that enables the fabrication of 3D microstructures such as lenses, pillar forests, cavities and channels embedded in a monolithic SU-8 structure defined in a single exposure step. Fabric...

For more than a century and half, silver/mercury amalgam fillings have been used in dental practice as the preferred tooth filling material. Currently, occupational exposure of dental staff to mercury vapor released from the amalgam, has been an issue of concern because of its possible adverse outcomes. Aim: The aim of this work was to determine the mercury body burden in dental staff exposed t...

(1) Dental wear is a common phenomenon in mammals. Its occurrence is influenced by tooth anatomy, animal physiology, biomechanics and behaviour. So far, investigations of dental wear in cetaceans have been scanty and superficial. We compare the frequencies of occurrence, location and intensity of dental wear in some species of dolphins from southern Brazil, South Atlantic Ocean. (2) Teeth of te...

In this contribution we present source properties and design considerations for a compact x-ray microscope operating in the water-window spectral region at 2.48 nm. The microscope will use a liquid-nitrogen-jet laser-plasma source with sufficient brightness, uniformity, stability and reliability for microscopy operation. The source is quantitatively characterized by calibrated slitgrating spect...
