background pain experience makes a serious anxiety for both patient and clinician before and after root canal treatment. pain is a complex psychophysiologic phenomenon. objectives the aim of this randomized control trial study was to evaluate the analgesic effect of odontopaste® and a corticosteroid containing compound medicament between root canal therapy appointments. materials and methods on...
Hybrid laser processing for precision microfabrication of hard materials, in which the interaction of a conventional pulsed laser beam and another medium on the material surface leads to effective ablation, is reviewed. The main role of the medium is to produce strong absorption of the nanosecond laser beam by the materials. Simultaneous irradiation with the ultraviolet (UV) laser beam and the ...
The past decade has seen a veritable explosion of research into the clinical applications of lasers in dentistry. Although lasers were once regarded as complex technology of limited use in clinical dentistry, dentists have becoming increasingly aware of the usefulness of lasers in the armamentarium of the modern dental practice, where they can be used as an adjunct or alternative to traditional...
In many cultures of the world, traditional percussion music uses mnemonic syllables that are representative of the timbres of instruments. These syllables are orally transmitted and often provide a language for percussion in those music cultures. Percussion patterns in these cultures thus have a well defined representation in the form of these syllables, which can be utilized in several computa...
Auscultatory percussion is a technique that is potentially useful to study the acoustic behaviour of the chest. However, finger percussion, as used in this technique, has not been previously assessed for consistency. We calculated the intrasubject variability and short-term reproducibility of this technique in 10 healthy subjects. We examined several indices of the output sound of two series of...
This paper proposes a novel smart surgical navigation system for intramedullary nailing in orthopedic surgery. Using a handle-integrated laser guidance module, the system can target a drill insertion point onto skin, indicating an accurate target position to perpendicularly access an invisible distal hole. The proposed handle-integration-based fixation of the laser guidance module precisely def...
This study was designed to examine the effects of low-energy laser irradiation on osteocytes and bone resorption at bony implant sites. Five male baboons with a mean age of 6.5 years were used in the study. Four holes for accommodating implants were drilled in each iliac crest. Sites on the left side were irradiated with a 100 mW low-energy laser (690 nm) for 1 min (6 Joule) immediately after d...
