Summary: Apical sealing effectivenes of lateral condensation, low-temperature gutta-percha (Ultrafil), vertical condensation of gutta-percha softened by means of three different laser devices (argon, CO2 and Nd:YAG), or composite resin photopolymerized by argon laser were studied. The results indicate that the Ultrafil technique, lateral condenstion technique and argon lasr softened gutta-percha produced good apical sealing results.

Summary: Intracanal laser softened gutta-percha (argon, CO2 and Nd:YAG lasers), Ultrafil and intracanal laser-cured composite resin techniques were compared with respect to the temperature elevation on the outer root surface. In this, in vitro, conditions, argon laser produced a rise in temperature of 12.9 degree C (gutta-percha) and 13.3 degree C (composite resin) respectively. The CO2 laser produced the rise in temperature of 10.3 degree C and, Nd:YAG laser produced the rise of 14.4 degree C. Ultrafil technique did not produce a measurable temperature changes on the external root surface.
Keywords: Argon laser, CO2 laser, Nd:YAG laser, thermoplasticized gutta-percha, dental root canal

Summary: Accumulation of the tooth cementum above the tooth cervix and over the enamel, forming thus cementum cingulum and sometimes covering the enamel surface in the location of the fissures, is a common feature in some herbivores and it is called Žcementum spursŽ. In this study, a rare case of cementum spurs in the population, from South Europe - Dalmatia (Adriatic coast of Croatia) is pressented. The authors conclude that the exsistance of cementum spurs (coronal cementum) as a higher instance, is a result of specific anatomical selfpreservation of the tooth in the alveolar socket.
Keywords: Cementum spurs

Summary: The objective of this research was to develop a technique that would allowe three-dimensional imaging of root canals utilizing computer image processing. The single rooted permanent human teeth with mature apices were analysed. The teeth were decoronated and fixed on boards with the long axes of the root perpendicular to the board. The cross-sectioning started at the root appex and continued in the coronal direction, roughly perpendicular to the long axes of the root. The samples were divided into two groups. The first five samples were sectioned 15 times each section being 0.5 mm thick, in order to obtain the three-dimensional reconstruction of the root and the root canal. The second group of five samples served for the graphical reconstruction of the apical portion of the root canal. The root apex of each sample was cross-sectioned 19 times and each section was 0,5 mm thick. After each section the root canal contour was defined utilising the calibrated net with coordinate system in the ocular stereomicroscope. The coordinates of the root canal cross-section countour thus determined, together with the value of the thicknes of each cut, were relevant input data for the reconstruction of the root canal cross/sections, longitudinal sectionc and for the final three-dimensional rebuild of the root and the root canal model. This technique appears to be highly accurate in determining the anatomy of the root canal system and may also be applied in other fields in dental research.
Keywords: Computorised analysis, root canal morphology, three-dimensional root canal registration

Summary: The quality of visible-light-cured composites depends on the capability of the light source to properly polymerize the material within specified exposure time. In this study, the degree of conversion of different composite materials (hybrids and microfilled) of light and dark shades was compared after illumination by standard curing unit and pulsed laser (468 nm) respectively. The degree of conversion was measured by Fourier Transform Infrared Spectroscopy. Results obtained by the analysis of the pulsed -laser -induced polymerization were significantly higher for all the materials and all the shades observed. All values of the degree of conversion were lower for dark shades of all types of composites, regardless of the polymerization method used. Besides the surface, better polymerization was recorded also at depths of 1.0, 2.0 and 3.0 mm, respectively. These values varied from 42.7% to 74.7 % for standard polymerization and from 59.7% to 84.5 % for pulsed laser caused by saturation effect induced by high power laser pulses.
Keywords: Pulsed laser, photopolymerization, degree of conversion

Summary: The purpose of this study was to determine the curing effects of 457.9, 476.2 and 488.0 nm laser emission lines. A Carl Zeiss ILA Argon ion laser was used with different power (130 mW and 60 mW) and exposure times (2 to 10 sec.). Four composite resins of lighter shade were investigated. It was demonstrated that the Argon ion laser produce photopolymerization effect on composite resins in very short time but the other physical and chemical consequences of this effect are yet to be examined.
Keywords: Argon laser, Polymerization effect
