Randomized Controlled Trial Comparative Study
Hemodynamic changes comparing 2% lidocaine and 4% articaine with epinephrine 1: 100,000 in lower third molar surgery.
An increase in blood pressure during dental treatment has been investigated with regard to potential medical risks since previous studies suggest that dental procedures may cause stress to the patient and, consequently, the cardiovascular system. The aim of the present study was to analyze hemodynamic changes following the administration of either 2% lidocaine (L100) or 4% articaine (A100) (both with epinephrine 1:100,000) in the surgical removal of symmetrically positioned lower third molars. ⋯ The hemodynamic parameters evaluated in third molar surgery with 2% lidocaine and 4% articaine (both with epinephrine 1:100,000) did not show significant differences.

The sectioned images and surface models of a cadaver head in the Visible Korean Project would be more beneficial if they were accessible and informative. To this aim, 3 policies were established: (1) the data are promptly obtainable and observable; (2) the graphic data are accompanied by explaining the anatomic terms; and (3) two-dimensional images and three-dimensional models are shown together. According to the policies, the following were attempted. ⋯ The sectioned images, outlined images, and surface models in the browsing software and PDF file can be downloaded from the homepage (anatomy.co.kr) free of charge. The state-of-the-art graphic information will hopefully assist medical students in learning head anatomy. In addition, the raw data are expected to contribute to the various clinical practice simulations.

Children with congenital craniosynostosis syndromes have a high incidence of obstructive sleep apnea (OSA). Obstructive sleep apnea has significant consequences including impaired growth, learning and behavioral problems, and cardiovascular morbidity. Adenotonsillectomy is the treatment of choice for OSA in otherwise healthy children. ⋯ Three children (60%) avoided tracheostomy and had no further airway surgery. Our results provide evidence to support the use of adenotonsillectomy in treating OSA in children with syndromic craniosynostosis. Adenotonsillectomy should be considered before tracheostomy or more major surgery in this patient group.

Since the introduction of Roentgen rays in medical diagnostics, mummies have been subjected to radiographic and cephalometric studies. These have, among others, the advantage of providing details that are not directly visible for inspection without the need to tamper with the relics. The acquisition of three-dimensional imaging techniques has also extended the possibility of noninvasive investigation, so that many famous mummies, such as those of Tutankhamun and Ramses II, underwent three-dimensional computed tomography (CT). ⋯ In our opinion, three-dimensional image processing of CT scan is useful to perform noninvasive morphologic investigations on archeological find, to allow virtual correction of postmortem artifact and to perform reliable cephalometric tracings.
