Emergency medical training for dental students.

Twenty-four of the thirty-two German universities that have dental schools replied to a questionnaire survey that showed that all the schools responding held lectures on the topic "Medical Emergencies" although this is not mandatory for registration. All of the universities in the former East Germany also offered practical training sessions as part of the curriculum. The proportion of West German universities offering such courses is only 60%. The basic essentials of the theory and practice of emergency medicine should only be taught in courses with mandatory participation.

Peripheral dentinogenic ghost cell tumor.

A case of dentinogenic ghost cell tumor, that has originated peripherally in the jaw, is presented and the literature reviewed with particular reference to the origin of the tumor. The total number of central and peripheral cases reported in the English literature is 10 and although mucosal infiltration is common, peripheral origin of the neoplasm could be verified in only 3 cases.

[Experimental studies on intraligamental anesthesia].

In an experimental study on animals the correlation between the pressure created by periodontal ligament injection and the distribution pattern of the anesthetic solution was examined. It was possible to demonstrate the penetration following intraligamental injection by scintiscanning of the mandibular bone. A correlation between pressure and distribution could not be established.

The orthopan tomoscintigram--a new application of emission computed tomography for facial bone scanning.

The exact regional correlation of findings of facial bone scans, planar or SPECT, to dental orthopan X-ray films (OPT) is difficult because of the very different projection techniques. To improve correlative imaging in this regard a projection algorithm was developed that uses SPECT data of the skull for reconstructing an orthopan tomoscintigraphic projection. Fourteen conventional SPECT slices of the upper and lower jaws were obtained during bone scanning. All mandibular slices were superimposed resulting in a horseshoe shaped structure, while was marked by an ROI which was divided into segments. All 14 SPECT slices were then masked by this segmental ROI, thereby marking the teeth-carrying bone in all slices. The information from this horseshoe like ROI is then transformed into lines. Line by line arrangement results in an orthopan projection, the orthopan tomoscintigram. This new display allows 1:1 true scale superimposition with the X-ray OPT and markedly facilitates correlative imaging.

Computerized tomography examination for the detection of positional changes in the temporomandibular joint after ramus osteotomies with screw fixation.

Changes in the position of the temporomandibular joint following sagittal splitting osteotomy of the mandibular ramus with screw fixation were examined using computerized tomography. Ten patients were involved in the study. Rotational movement of the condyle-bearing fragment was most commonly seen in the transverse computer tomograms. However, the use of screw fixation seems to cause no major malpositioning of the condyle-bearing fragment.
