    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: 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: 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: 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 2s at 155 mW.

    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: 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.

    Summary: Morphologic, temperature and permeability changes of the canal dentin wall induced by CO2, Nd:YAG and argon lasers in vitro were 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.

    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.
