A contribution to the quantitative analysis of transmitted images.

The scope of this paper is to contribute to the analysis of the problem of connecting two, relatively distinct, mostly technological, aspects of modern pathology. The authors analyze the differences between the values of morphometric and other parameters, such as: area, density, perimeter, etc. obtained on the same set of images before and after transmission. The results obtained prove that the differences due to the compression-transmission-decompression module, which is inherent to the image transmission process, are negligible.

Concept of telepathology in Croatia.

The authors proposed a hierarchically organized telepathology system in Croatia connecting smaller hospitals with a single pathologist to three regional centers and connecting these regional centers to the National center in Zagreb. The national center in Zagreb should later be connected further with all highly specialised pathological units in Zagreb and with international centers. This will offer broad possibilities of pathological consultations which is the primary aim of this system. Further, clave cooperation with other participants in telemedicine should be developed, as well as investigation on image analysing of transmitted pictures.

Temperature and surface changes of dentine and cementum induced by CO2 laser exposure.

The thermal effects of a CO2 laser on the external root surface and inside the root canal were studied in vitro by means of computerized infrared (IR) thermography and a digital thermometer. One-hundred-and-eighty tooth roots with single root canals were irradiated internally and externally with laser power set at 0.5, 1, 1.5, 2, 3 and 4 W. The laser was used in two operating modes: pulsed (pulse 0.5 s) and continuous mode with exposure time of 10 s. Under the conditions of this experiment, temperature rises of between 1.5 and 19.1 degrees C at the external root surface and 1.5 and 12 degrees C inside the root canal and horizontally across the sectioned root surface were recorded. The results obtained with IR camera showed a higher temperature on the external root surface than the digital thermometer during and after lasing the root canal. Scanning electron microscope (SEM) analysis revealed that even low laser energy significantly damaged the external root cementum surfaces.
