Summary: The presence of imunoglobulins G, A and M was studied
inhuman dental pulps using a quanitative method of radialimmunodiffusion.
The results indicated IgG to be present in 100%, IgA in 15% andIgM in 8% of
13 pulp samples affected by chronic inflammation.The mean values of IgG,
IgA and IgM thus determined were 84,3,4,4 and 1,4 mg/g protein,
respectively. In intact pulp tissue,however, no presence of immunoglobulins
G, A and M could bedetected using the same method as above. The
predominance of IgGpointed to immunologic reactions of early types II and
IIIhypersensitivity.

Summary: Laser effect on enamel is manifested as consequence
oftemperature changes. Enamel melts, vaporises and a crater, andfissures
are formed. Retention surface for anchoring of compositeresin was obtained
in intact aproximal surfaces of premolars withCO 2 laser (0,5, 1 and 3 W,
sport size 1 and 1,5 mm, 0,2 and 0,5s). The study results reveal composite

Summary: There is an existing problem of cummulative hazarduos
effect ofviolet and near ultra-violet light which is produced by
standardpolimerization units. Another restrict is shallow depth of
cure,particulary of darker composite shades in premolar and molarregion.
Searching for better light source we used indiumresonance lines from
several indium high pressure lamps andtested curing effect on three
different composite resins. Theoverall results are better with the lamp in
which two strongresonance lines of indium are present, rather than with a
lampwith just strong resonance line.

Summary: Cervical lesions and their proper treatment still represent
aconsiderable professional problem. The incidence of these lesionsincreases
with aging of the population. In this study, a novelapproach to the
treatment of these lesions using type II glassionomer cement, with an
additional possibility of the applicationof the final composite layer to
attain the maximal estheticeffect, was investigated. This filling was
founded to haveadvantages over both classical fillings and the
compositematerials alone because it chemically bonds to dentin, exerts
amarked caries protective effect through a continuous release offluor ions,
and provides the best esthetic effect in combinationwith composite
materials.

Summary: The teeth were cut vertically in half with a thin
diamonddisc. One half of each tooth served as a control and the otherhalf
was irradiated using the CO 2 laser. Laser energy wasapplied at incisive
labial surface (15 W, 0,5 s, spot size 3,5mm). After experimental
demineralisation with 0,2 M sodium acetatand 0,1 M lactic acid solution for
10 days, dissolved calcium andphosphorus were analyzed in the
demineralizating solutions usingatomic absorption spectrofotometry and
colorimetric method(method described by Lowey), respectively. Ca and
Pconcetractions in demineralizing solutions per unit surface areawere lower

Summary: The aim of this study was to determine the amount
ofstimulated saliva and salivary pH in diabetic patients and innormal
subject, and to study the possible difference in theoccurrence of caries.
Results pointed to a significant decreasein the amount of stimulated saliva
in insulin dependent diabetics(1,22 ml/min vs. 1,43 ml/min in normal
subject). In all diabeticpatients, a significantly lower salivary pH was
recorded ascompared to normal subject. The DMFS index was
significantlyhigher in both insulin dependent nd non-insulin

Summary: Composite resins are, undoubtely the most important
discoveryin dental science in last three decades. Until now the
threegenerations of composite resins have been developed. The first ofthem,
composite materials with macrofiller are not in operativeuse today due to
their shortages. Composite materials withmicrofiller and composite
complexes with microfiller are good forfrontal teeth while the hybrid
composite resins are good for thebicuspids and molars. Moreover, three
generations of dentinadhesion materials for better adhesion of composite
resins ondentin surfaces have been used.

Summary: The acid etching technique a high micromechanical adhesion
andhigh degree of physical bond of composite resins to enamel.Developing an
effective adhesive bond to dentin is more difficultdue to the chemical and
biological complexity of dentin. Manytechniqes and means have been
developed with the purpose toadhesive chemical bond of composite resin to
organic andanorganic components of dentin. Dentin bonding agents provide
themost appropriate conditions for bonding of composite resins toacid

Summary: Temperature changes in enamel tissue and the pulp
chamberunder the influence of a CO 2 laser were measured by directmethods
in vitro. X-ray diffraction analysis revealed a-Ca 3(PO4), the high
-temperature modification of enamel hydroxylapatite,thus indicating that
the enamel melting temperature was above1,000 C in the interaction area of
laser (continuos wave, 15 sexposure time, 1 mm spot size) and tissue.
Powers of 0.5 and 15 sexposure time, 1.5 mm spot size, and 10 s exposure
time vaporizeand carbonize dentin tissue at the cavity bottom of class
Ipreparation molars. The observed temperature rise of 4 Cindicates that
thermal injury to the pulp tissue does not occur.

Summary: Twenty-six extracted first lower permanent molars were
usedin the study. A diamond ring was used to separate the region ofrooth
ramification from the rest of the tooth. The specimens weregold-evaporated,
observed under an electron microscope (SEM)and photos of the findings were
taken. Most frequently, 3-4 largeaccessory canals of 51-150 um in diameter,
connecting the pulpchamber bed with the surface of root ramification, were
observed.These accessory canals gain greatly in importance when a diseaseof
the pulp or regional peiodontium occurs, allowing theinfection and
inflamation to spread through them from one tissueto another.

Summary: There are two drawbacks of standard
photopolymerizationunits: relative inability of a complete cure of darker
compositeshades in premolar and molar regions, and hazardous effect
ofcuring light on the eyes of the dentist. An argon-ion laser wasused as a
source for photopolymerization of several light shadecomposite resins. The
depth of cure was measured at threedifferent wavelenghts (457.9nm, 476.5 nm
and 488.0 nm) and in thelaser multiline mode. The depth of cure
measurements wasdetermined with a micrometer. The best results were
obtained witha 476.5 nm laser line for Silux composite: more than 3.8 mm in

Summary: Spectra-Physics 2020 argon-ion laser emission line of 476,5
nm,which corresponds to the peak of the camphorquinone absorptioncurve was
used to cure some dental composite resins. In this waypossible future
polymerization method was simulated. Compositeresin samples illuminated by
7, 12 and 17 mW laser lightdispersed to the diameter of 8.0 mm, showed
significantlly highercuring depths in comparison with a standard unit,
while a laserbeam of 4.5 mW power showed ineffeciency. The results
encourageresearch in diode laser photopolymerization for improving
theproperties of dental fillings, at the same time avoiding thedrawbacks of
the wide spectrum range produced by conventionalcuring devices: eye hazard
and pulp overheating.

Summary: This paper is addressed to talon cusp, rare
odontogenicanomaly which projects from the cingulum area of maxillary
ormandibular teeth. The shape of the cusp resembles an eaglestalon. Talon
cusp is composed of normal enamel and dentin, andmay contain pulp horn.
Usually, talon cusp tooth has "T" or "Y" shape.
The diagnostis of talon cusp is based on clinical andradiographic
appearance.
It is necessary to recognize this anomaly because it arises manyproblems
and requests multidisciplinary approach to treatment.

Summary: Morphological anomalies of the teeth may appear in
everydevelopmental stage of the embryological life and they result
indifferent morphological entities. Due to the difficulty indistinguishing
fusion from gemination, both morphologic entitiesare called "double teeth".
The purpose of this study was toestablish the frequency of the "double
teeth", distribution ofanomalies between sex and their association with
otherodontogenic anomalies, but it was not found. The investigationwas
carried out on the 2832 plaster models. The "double teeth"has been found in
three male patients (0.9).

Summary: In order to improve the quality of composite
resinphotopolymerization, a series of experiment was made using
pulsedlaser. Three different experiments were carried out withdifferent
shades of composite resins Helioprogress and Heliomolar(Vivadent,
Liechtenstein). The best results were achieved at 470nm regardless of the
amount of filler and pigment. The resultswere compared with a commercial
device (Heliomat). It is expectedthat pulsed laser polymerization will
improve the degreeof monomer conversion, decrease a temperature rise in
thecomposite resin sample and in that way avoid wall-to-wallcontraction.

Summary: Transverse and tensile resistance of a dentin-bonded
composite resin was tested in this study. The composite resins (Fluorocore,
Coradent and Coracore) were retained routinely by a dentin adhesive
(Syntac) on dentin samples. The specimens were mounted on a mechanical
testing device, and each of the 23 specimens was loaded perpendicularly to
its long axis. The transverse force was applied at a crosshead speed of 0.5
mm/min until failure occured. The next 22 specimens were loaded in parallel
with their long axis in the same conditions. All the three materials showed
a satisfactory compressive shear bond strength, but transverse resistance
was inadequate and restorative pins had to be used

Summary: The temparature elevation at the external surface of the
low-temperature Ultrafil system cannule and at the surface of the extruded
thermoplasticized gutta-persha mass were studied. Ultrafil cannule warmed
for 15 min exhibited a means surface temperature of 82.26 degree C
immediately after withdrawal from the heater. The highest cannule metal
applicator surfaces mean temperature 34.52 degree C was recorded after 8 s.
The gutta-percha mass extruded from the cannule fluctuated in temperature.
Thus, the highest mean temperature at the needle orifice of 53.90 degree C
and 45.22 degree C at the gutta-percha mass extruded for 3-5 mm, was
recorded after 12 and 8 s, respectively

Summary: This in vitro study evaluated the ability of the commercial
Amalgambond liner to reduce microleakage between amalgam restorations and
tooth structure. At the occlusal surface of the 24 extracted human third
molar, conventional Class I cavity was prepared. Cavity walls of the
samples in one group (N=12) were covered with two layers of Amalgam liner
before thje a,algam was packed into the cavity. The rest of the samples
were filled only with amalgam. After 7 days in 0.9% saline solution at 37
degree C, the samples were thermally stressed by subkecting them to the 300
thermocycles between a 0 and a 55 degree C bath. After that the samples
were immersed into the 1% methylene blue dye solution for 7 days. The teeth
were sectioned in a bucco-lingual direction through the restorations. The
issue was examined by direct measurement of dye penetration between amalgam
and cavity walls. The cavity previously prepared with the Amalgam liner
showed statisticaly significant less dye penetration compared with the
cavity without Amalgam liner (p<0.05).

Summary: The apical sealing ability of a standard lateral and
vertical condensation techniques, as well as single guta-percha technique
and combined technique was measured and compared. The root canals of 46
single rooted teeth were instrumented using a step back technique. The
apical leakage was measured using a stereomicroscope after submerging the
root apices in a 1% methylene blue dye water solution. The best results was
obtained with lateral condensation technique (mean 0.93 mm, SD
0.80)followed by vertical condensation technique (mean 1.79 mm, SD 1.02)
and single gutta-percha cone (mean 1.93 mm, SD 1.38). The poorest result
was obtained with combined obturation technique (mean 1,97 SD 0.89). The
difference between lateral condensation obturation technique and combined
technique was statistically significant (p>0.05)

Summary: The root canals of single rooted teeth were obturated with
Ultrafil technique, modified Trifecta technique with both SuccessFil
gutta-percha and Ultrafil regular Set gutta-percha, and standard lateral
condensation technique. The sealing ability was evaluated according to the
extent of methylene blue dye penetration into the apical canal space. There
was no significant difference in apical dye leakage among these three
techniques however, overextrusion of the gutta-percha was found in 80% of
the samples obturated with Ultrafil technique. Modified Trifecta technique
seems to be effective in both apical sealing ability and extrusion control.

Summary: The high temperature at the target area induced by argon,
CO2 or Nd:YAG laser can produce vaporisation of the created smear layer and
melting of dentine. Such midified surface can cause the changes in
permeability of the dentinal tubules. Before the intracanal lasing, the
created smear layer should be removed. If not, the laser energy can disturb
the surface of the smear layer and, as a consequence the increase of the
permeability instead of decrease can develop. This can be express
particulary in the middle third of the root canal when laser beam is
parallel rather then perpendicular to the canal wall. Inside the root canal
the output laser power should not exceed 1W and the pulsed or repeated mode
should be used. The single irradiation time should not exceed 1 second.
However, intracanal heat produced by the laser can be used for softening
the gutta-percha particle seated at the apical stop. The argon laser may be
a better choice for this purpose than CO2 or Nd:YAG laser

Summary: The argon laser has emission lines at 488 and 514.5 nm
wjich should make it well suitable for initiating the polymerization of
light activated composite resin. Homogenous penetration of the composite
resin by argon laser reduces shrinkage towards the curing light and some
properties of the resin can be enhanced. This can be accomplished with only
about 10 s of polymerization time. Another advantage of the argon laser is
the possibility of argon light beam to transmit through optical fiber that
allowed introducing the laser energy into the root canal. In order to
improve the penetration of the composite resin into the dentinal tubule,
the smear layer created during instrumentation should be removed. After
removing the excess bonding agent, composite resin should be plugged into
the root canal. Laser action should be started in a front of the canal
orifice and than the fiber must be introduced into the canal and slowly
pushed toward the apical portion. Second lasing is performed during
withdrawal of the fiber. After withdrawing the fiber, an additional amount
of composite resin should be plugged into the canal and polymerized in the
same manner mentioned above.

Summary: Dental amalgams has been the material of choice for the
posterior fillings for the past 150 years. Presented in this paper are the
historic developments of amalgam, its obligatory composition, as well as
the division of different types of amalgam according to the quantitative
content of copper and the shape of the particles. Also, the properties of
amalgam with special regard to its toxicity are listed. It is well known
that, over the past few years, attacks on dental amalgam have intensified,
both in scientific and popular literature, concerning its possible
pathologic impact on human body. Enumerated in the paper recommendations by
the American Dental Association (ADA) on the use of dental amalgam. In view
of the scientific research available, there is no scientifically founded
evidence of the amalgam fillings being noxious.

Summary: In this study, the electrical potential of four different
commercial dental amalgasms an in vivo conditions was studied.
Additionally, the effect of polishing of the amalgam filling on electrical
potential, as well as the presence of prosthetic metal and their influence
on electrical potential were also investigated. The measuring of the
electrical potential was performed at the gingiva and fresh amalgam
fillings. After seven days, the potential was measured again at the same
fillings before and after polishing of the amalgam surface. The difference
in electrical poptential between polished and non-polished amalgam fillings
was statustically signifivant in all tested dental amalgams (p<0,01).
Presence of prosthetic metals in the oral cavity was not influenced on the
electrical potential of amalgam filling. It was observed that electrical
potential of amalgam fillings lowers due to the ageing and polishing.

Summary: Periapical cyst biopsy was performed in 16 subjects to
asses their immune response. Total protein were determined by Lowry s
method, and IgG, IgA and IgM by radial immunodiffusion. Immunoglobulin
values were expressed in mg/g total protein. IgG and IgA were found in 100%
and IgM was detected in 33% of the samples. Mean values of IgG, IgA and IgM
in periapical cysts were 159.4, 25.6 and 1.8 mg/g total protein,
respectively. The values of IgG, IgA and IgM found in the periapical cysts
suggested their possible local synthesis and immune response, which may
play a role in the pathogenesis of periapical cysts.

Summary: Polymerization shrinkage is a negative consequence of the
setting of composite materials. It usually leads to the formation of gaps
around the cavity margins, which is resulting in microleakage, marginal
discoloration, reccurent caries and possible tooth sensitivity. To overcome
the polymerization contraction, it is necessary to treat the cavity walls
before the composite material application. The removal or modification of
smear layer appears to play a significant part in the mechanism by which
the dentin and resin become linked. In shallow cavities, it is sufficient
to use dentin adhesives, but deeper cavities use of light-hardened
glass-ionomer cements is required. It enables penetration, impregnation and
entanglement of the methacrylate-based monomers into dentinal substrates,
were they polymerize in situ and create zones of resin-reinforced dentin or
Žhybrid layersŽ. Other ways of prevailing the volumetric contraction are
the volumetric contraction are the application of hybrid composite
materials and use of light-curing device with minimal heat-generation and
maximal polymerization effect. Thus, the marginal gap formation, the major
problem in composite resin tooth restoration, can be prevented by
overcoming the polymerization contraction.

Summary: The quantity analysis of residual double bonds or free
radicals in the polymer network, are the most reliable methods for
determining the degree of conversion. This study evaluates the degree of
conversion and the light transmission measurements of three different
composite resin products and two different shades (the lightest and the
darkest one). The correlation between the degree of conversion and the
light transmission measurements is noticed. Absorption and scattering by
filler particles would continue the attenuation of the light through the
composite resin sample and consequently reduce the degree of conversion. A
dependance on the filler loading amount and the composite resin shade exist
as well. The results confirm that hybrid materials and lighter shades could
ensure higher conversion than microfilled composite resins as well as
darker and more opaque shades. It is also noticed that the illumination by
the curing unit of low output should be prolonged and the increments should
not be thicker then one mm.

Summary: This investigation deals with a complex relationship of an
altered saliva quantity and pH on caries appearance in individual suffering
from diseases of the upper digestive tract in relationship to healthy
individuals. Greater caries prevalence was found in individuals suffering
from diseases of the upper digestive tract. Caries prevalence was
significantly greater as stimulated salivary secretion and pH was lower in
both groups. There was no significant difference in caries prevalence and
different pH of non stimulated saliva in the control individuals.
Individuals suffering from chronical diseases of the upper digestive tract
are exposed to an increased caries risk when accompanied with a
longlasting of frequent low salivary flow and decrease salivary pH.

Summary: Current photopolymerization devices do not produce
sufficient degree of conversion, especially for darker shades in undercuts.
We tried Spectra-Physic 2020 Argon ion laser emission line that
corresponds to the peak of camphorquinone absorption curve (476.5) for
curing of posterior composites. Low power laser beam dispersed to the
diameter of 7 mm was used to avoid refered temperature rise and high
contraction values.The results show similar depth of cure for Heliomat
polymerization unit and laser beam of 7 mW. Coherent light of 12.5 and 17
mW show significantly better results compared with standard units. Low
power laser light can produce satisfyng depths of cure, particularly for
darker shades.

Summary: Standard polymerization devices produce about 60%
conversion rate in composite resin filling. The light source consisted of
the pump laser and dye laser. The laser pulse duration was 20 ns, the total
number of the pulses was 300 and the energy of 0.6 mJ with repetition rate
of 10 Hz. The wavelength was changed from 465 to 495 nm in steps of 5 nm
with 30 s illumination time. Experiment was made with three different
shades of composite resins Helioprogress and Heliomolar. We expect
photopolymerization in the pulsed regime to improve the degree of
conversion, to decrease a temperature rise in the sample and in that way
avoid wall-to-wall contraction.

investigated.SEM analysis of the lased surface revealed that all three
lasers are capable to produce vaporisation and melting of the dentine
surface and disturbing of the surface of the created smear layer. The
decrease or increase of dentin permeability are conected to the status of
the smear layer and the dentine surface following lasing.

Summary: Some drawbacks of currently used photopolymerization
necessitate the search for new light sources. In this study, comparison was
made between the degree of conversion of two hybrid composites of light and
dark shades, as illuminated by conventional halogen lamp and pulsed laser
upon the surface and at depths of 1.0, 2.0 and 3.0 mm. In order to compare
these two methods the total energy during the illumination was kept equal
or somewhat smaller than in case of halogen lamp illumination. Composite
resin samples were prepared in the same way for both polymerization
methods. The degree of conversion of cured samples was measured by FTIR -
Spectroscopy. Results obtained by the analysis of the pulsed laser -
induced polymerization were significantly higher for all the materials and
all shades observed.The measured values of the degree of conversion were
analysed using analysis of variance. Very weak dependance of the degree of
conversion, between the surface measurements and those at 3.0 mm depth were
observed in case of pulsed laser polymerization due to the saturation
effect induced by the high power nanopulses and monochromatic wavelength of
468 nm.

Summary: The effect of carbon dioxide and Nd:YAG laser beams on the
extracted human teeth were examined. Laser effect on hard dental tissue is
manifested as a consequence of temperature changes. Different wavelengths
are absorbed differently by dental tissue. The obtained results indicate
that the Nd:YAG laser causes bigger destruction on dentin (Carbonification
and cracks) when compared to the effect of the CO2 laser beam of the same
energy. Temperature changes of the enamel tissue under influence of CO2
laser were measured by the indirect method. X-ray diffraction analysis
revealed presence of Ca3(PO4)2 (but not the presence of Ca4(PO4)2O) which
is a high-temperature modification of heated human enamel. The presence of
such modification of the enamel indicate that the enamel was melted with
the temperature higher than 1000 degree C. In the pulp chamber, the
temperature changes were measured by the thermal probe inserted into the
cavum through the whole previously prepared at the bifurcation level, as
well as at the enamel surface at the approximal side of the crown. CO"
laser energy applied at the bottom of cavities of Class III, IV and V,
vaporised and carbonised the dentin surface with a very little influence on
the temperature inside the pulp chamber. CO2 laser could be used for
removal of small mass of carious dentin and for atching of the enamel
surface.

Title: The application of the new light sources for the
photopolymerization of composite resins

Summary: Current photopolymerization devices do not provide complete
cure of darker shade composite fillings in undercuts. Some of them are
harmful for the eyes of the operator, while the others produce unnecessary
overheating of the tooth. In-Hg and Zn-Na high pressure lamps, as an
alternative light sources, do not produce adequate depth of cure, due to
the small amount of total light intensity in the area of optimal absorption
of the photoinitiator (468 nm). Eu and Sr high pressure lamps could give
better results, because of very suitable wave-length of corresponding
resonant spectral lines. Coherent radiation produced by Ar laser at 476.5
nm gave very good curing depth values for different composite brands.
Anticipating technological development, a method of improving
polymerization is proposed, simultaneously eliminating undesirable effects
of standard curing lights. For more complete understanding of the nature of
photochemical reaction initiated by the laser beam, an analysis of
microhardness, polymerization shrinkage, temperature changes and the degree
of conversion in composite resin sample is to be done.

Summary: Photocurable composite resins are of indispensable import
in modern esthetic dentistry. Some disadvantages of standard curing units,
such as a decreasing light output with time and distance, particularly of
darker shades, results in a relatively low degree of conversion and
necessitate the search for new light sources. In this study, the quality of
polymerization of different composite materials (hybrid and microfilled) of
light and dark shades was evaluated after illumination by standard curing
unit and pulsed laser set at 468 nm. The present investigation reveals that
laser nanopulses are extremely piercing and ensure almost the same
polymerization at the surface and at the bottom of the sample due to the
saturation effect. In addition, a coherent laser light at a single
wavelength of 468 nm is more effective than the range of 400-500 nm,
characteristic of standard curing units. High intensities in pulsed laser
polymerization exhibit some other advantages apart from increased monomer
conversion. It ic known that polymerization shrinkage and degree of
conversion are antagonistic goals. In this experiment, amount of energy
illuminating the sample surface was 5 time less (4 J) in case of pulsed
laser curing. Nanopulses are very short and allow cooling of the material
between the laser pulses, which differentiates this method from continuos
wave laser and standard polymerization lamp thus results in a significantly
reduced polymerization shrinkage.

Summary: The purpose of this study was to determine the marginal
leakage around the enamel and dentin margins of composite restorations with
various adhesives. 40 extracted premolars that had been stored in
artificial saliva were selected. Cavities (dimensions 3x3x1.5 mm) are
prepared on the buccal and lingual surfaces and filled with appropriate
adhesive and composite resin. After that restored teeth were termocycled in
the bath. After that the entire tooth surface was sealed with vax. The
teeth were exposed to contrast solution embedded in acrylic resin and
sectioned longitudinaly through the center of the restoration.The depth of
a dye penetration was considered as an indicator for marginal leakage.
Statistical analysis demonstrated more marginal leakage around dentine
margins. Though not a single one of the examined adhesives did fill out
completely marginal seal in dentine, the Syntac adhesive has proven to be
the most effective in comparison with the rest of adhesives used in this
study.
