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.

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.
