   Title in English:	Light intensity of curing units in dental offices in Zagreb, Croatia
   Title in Croatian:	Intenzitet svjetlosti polimerizacijskih uređaja u ordinacijama dentalne medicine u Zagrebu, Hrvatska
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	Objective: Photopolymerization unit is an essential part of every dental office. The intensity of light curing units gradually decreases with time and can lead to poor polymerization, which cannot be detected clinically immediately after illumination. The purpose of this study was to examine whether the intensity of light curing units in dental offices in Zagreb satisfies minimum operational requirements. Materials and methods: The light intensity of 111 curing units was measured using radiometer (Bluephase® meter, Ivoclar Vivadent, Schaan, Liechtenstein). Six measurements were taken for each unit, three at the beginning of illumination and the other three at 35-40 seconds from the beginning. Data were also collected about the type of curing unit, manufacturer, age, frequency of use and the existence of integrated radiometer. Results: Light intensity lower than 300 mW/cm2 had 34% of curing units and 44% lower than 400 mW/cm2. The average light intensity of the remaining curing units was 675.3 mW/cm2. This study included photopolymerization units used in Zagreb which were five years old on average. Conclusion: Though the average light intensity of curing units in Zagreb fulfill the general requirements for efficient polymerization of composite resin materials, the fact that more than one third of curing units are ineffective should alert dentists to regularly monitor their appliances.

   Abstract:	Purpose: The aim of this study was to evaluate the dentine wear after brushing with powered toothbrushes with different brush head size and different load applied in comparison with manual toothbrush. Material and Methods: Powered toothbrush Sonicare Elite with mini and standard size brush heads at 90g and 150g vertical load, and the manual toothbrush Oral-B-P35 with a vertical load of 150g, were used as a control group. Toothbrushing machine with different number of strokes was used for dentine abrasion assessment. For Sonicare-Elite with standard size head 12000 strokes was used, for Sonicare Elite with mini head 18000 and for manual toothbrush 12500 strokes. 3D-Laser scan was used for evaluation of dentine wear. The highest dentine wear was recorded using manual toothbrush (107.26μm), while the lowest using Sonicare-Elite with standard size head at 90g vertical load (47.7μm). Results: No statistical significance was found between powered toothbrushes with: mini head (90g load), standard head (90 and 150g load) and between mini head of powered toothbrushes at 150g vertical load and manual toothbrush. Conclusion: Powered toothbrushes with different brush head size and different load applied caused different tooth wear: the smaller the brush head and the higher the load is, the higher the dentine wear is.

   Title in English:	Degree of Conversion and Temperature Increase During Composite Polymerisation with Led Units of Different Intensity
   Title in Croatian:	Stupanj konverzije i temperaturni porast kod kompozita polimeriziranih LED-uređajima različitog intenziteta
   Type of Article:	original scientific paper
   MeSH:	COMPOSITE RESINS POLYMERS
   Abstract:	The appearance of LED curing units for composite materials polymerization has almost completely replaced halogen curing units. The main disadvantage of halogen curing units was a temperature rise during the polymerization. Earlier generations of LED devices made the temperature rise negligible. The newest generation of LED curing units makes a higher degree of conversion due to higher light intensity, but also brings to question the temperature rise during the composite materials polymerization. Aim: The purpose of this study was to measure the degree of conversion and temperature rise in composite resin samples. Material and Methods: The samples were polymerized by curing modes of different light intensity of four LED units: Bluephase, Bluephase C5, Bluephase C8 and Bluephase 16i (all units Vivadent, Schaan, Liechtenstein). The degree of conversion was measured by FTIR spectrophotometer, while for the temperature it was measured using the thermometer ELV Pyroscan (Leer, Germany). Results: The highest degree of conversion was achieved in the case of composite resin samples polymerized with soft-start mode (SOFT) of Bluephase 16i unit, while the lowest degree of conversion was achieved in the case of polymerization with Bluephase C5 curing unit. The highest temperature rise was recorded in the case of composite samples polymerization with high intensity mode (HIGH) and SOFT mode of Bluephase 16i, while the lowest in the case of polymerization with low intensity mode (LOW) of Bluephase C8 unit. Conclusion: According to the results of this study, it can be concluded that higher degree of conversion brings higher temperature rise, regardless of composite material used.

   Type of Article:	original scientific paper
   MeSH:	DENTAL CARIES LASERS + therapeutic use
   Abstract:	Modern concepts in caries treatment require highly specific and sensitive methods of caries detection opposed to the conventional visual – tactile method. Unnecessary removal of sound dental tissue is quite often due to false – positive caries diagnosis. On the other hand, lesion can be undetected for a long period of time. DIAGNOdent (KaVo, Dental GmbH, Germany), a laser fluorescence – based device, presents an important turnover in diagnostic procedure. DIAGNOdent reading is highly accurate, repeatable, simple, safe, and ensures a long-term lesion monitoring because the result is quantified. The purpose of the study was the comparison of visual - tactile method of caries detection with laser fluorescence. Out of 960 teeth, caries was diagnosed in 90 teeth (9,4%) by DIAGNOdent. Using the visual – tactile method, dental caries was diagnosed in 58 teeth (6%). Absolute disagreement was found in 3,54% cases. More than half of lesions that have remained undetected were in the category of enamel surface caries (DIAGNOdent values 14-20). McNamar’s test showed statistically significant differences between DIAGNOdent based caries detection and visual – tactile method.

   Abstract:	Minimally invasive dentistry holds an important place in the treatment of caries lesion. Introduction of laser fluorescence as a diagnostic and ozone as a therapeutic means finds more frequent usage in both preventive and curative dentistry. DIAGNOdent device (KaVo, Germany) is based on laser fluorescence which enables early diagnosis as well as monitoring the development of caries lesion while use of ozone with HealOzone device (KaVo, Germany) provides painless treatment. Even though there are number of indications for use of ozone in dentistry, most important is therapy of caries lesions. Purpose of this investigation was to observe the effect of ozone applied via HealOzone device on the total of 70 primary fissure lesions previously detected with DIAGNOdent device and to determine whether there is a decrease in lesion demineralization values between first visit, first and second recall after one and two month period. Results showed statistically significant difference in demineralization values recorded on DIAGNOdent scale between first visit and every repeated recall (p<0,001).

   MeSH:	COMPOSITE RESINS DENTISTRY, OPERATIVE
   Abstract:	Composite materials shrink during the polymerization process which lessens their clinical value. Modifications of composition of the composite material and application technique proved inadequate for compensation of polymerization shrinkage, and therefore modification of polymerization modes was attempted. The polymerization modes of lower intensities will enable prolongation of the pre-gelation phase and consequently greatly decrease the total amount of shrinkage. The purpose of the study was to determine the polymerization shrinkage of Tetric Ceram (Vivadent, Schaan, Liechtenstein) and Filtek Z 250 (3M/ESPE Dental Products, St Paul, MN) composite materials by digital holographic interpherometry. Samples of the composite material were polymerized by three modes of various intensities (medium, exponential and standard) Elipar Trilight halogen curing unit (3M/ESPE, Seefeld, Germany). Highest values of the polymerization shrinkage were recorded for the polymerization mode with highest light intensity.

   Type of Article:	original scientific paper
   MeSH:	COMPOSITE RESINS DENTISTRY, OPERATIVE TEMPERATURE
   Abstract:	One of the most important side effects of composite material setting using halogen devices besides polymerization shrinkage is temperature rise. The temperature rise is in direct relation with the strength of polymerization light intensity and as intensity grows so does the temperature. Since many polymerization devices exist on the market today capable of producing several different polymerization modes with different distribution of light intensity within the polymerization interval as well as different strength, the purpose of this study was to examine the influence of different polymerization programs (modes) on temperature rise in a sample of composite material. In the experiment Tetric Ceram (Vivadent, Schaan, Liechtenstein) and Filtek Z 250 (3M/ESPE Dental Products, St. Paul, MN) composite materials were used. Composite material samples were polymerized by Elipar Trilight halogen device (3M/ESPE, Seefeld, Germany) with three polymerization modes of various intensities (middle (ET ), exponential (ETE) and standard (ETS)). Highest temperature rise was noted after 40 seconds at highest intensity mode (standard mode), while lowest temperature rise was noted at exponential mode after 10 seconds and at medium intensity mode after 40 seconds.

   MeSH:	COMPOSITE RESINS DENTISTRY, OPERATIVE
   Abstract:	Degree of conversion of composite materials is an important factor that influences both quality and longevity of the composite restoration during polymerization. Besides the components of the composite material, degree of conversion is greatly influenced by properties of the light source and polymerization time. The purpose of this study was to compare the effect of three polymerization modes of various intensities (medium, exponential and standard) of Elipar Trilight halogen curing (3M/ESPE, Seefeld, Germany) unit on samples of Tetric Ceram (Vivadent, Schaan, Liechtenstein) and Filtek Z 250 (3M/ESPE, Seefeld, Germany) on the surface and at 2 mm depth. For determining the degree of conversion, Fourier transform infrared spectroscopy (FTIR) was used. Results of the degree of conversion measurement showed the highest degree of conversion when using light source of highest intensity as well as a higher degree of conversion on the surface than at 2 mm depth regardless of the type of composite material and light intensity used for polymerization.

   Type of Article:	original scientific paper
   MeSH:	INTERFEROMETRY COMPOSITE RESINS
   Abstract:	Polymerization of composite filling is considered to be an importantfactor in achieving longevity of the restorative treatment. Quality of the polymerization influences physico-mechanical characteristics, color stability, volumetric changes of restoration and biocompatibility of the material itself. Polymerization shrinkage is an unavoidable consequence of setting of the composite material. So far, it has been measured by several different methods. Digital holographic interferometry, a method described in this study, is the only procedure that enables direct monitoring of the polymerization shrinkage for every second of polymerization of the composite material. Values of the polymerization shrinkage obtained by this method correspond with the values obtained by other methods.

    Abstract:	Caries is a disease of hard dental tissue caused by the following factors: host (the tooth), cause (microorganisms), environmental influence and time. With improved technology new, contemporary, methods of diagnosing caries lesions have been introduced, one of the most important being laser fluorescence. Parallel with the development of new diagnostic methods, the classical “Black’s principle” of cavity preparation, was replaced, first with “minimally invasive non-traumatic dentistry”, and more recently with “ozone therapy”. Bactericide and disinfective properties of ozone enabled a new concept of “painless therapy” in treatment of caries lesions.

    Abstract:	Damaged incisal edges of the upper central incisors are considered to be an important as well as a relatively complex problem in restorative dentistry because the degree of damage is minimal yet esthetical demand provision of long-lasting reconstruction complex. There are several techniques for provision of incisal defects, the leastinvasive being direct technique with composite resins. The purpose of this study was to present one of the possibilities for reconstruction of trauma damaged incisal edge. A 22 year old patient after being strike by a hard object, sustained fractures od enamel and part of the dentin on the incisal edge. Previously performed restorative treatmentwas not satisfactory, so a new procedure was undertaken, using Artemis (Vivadent, Schaan, Liechtenstein) microhybrid composite material with a wide spectrum of shades for enamel and dentin simulation as well as special effects. Opaque shades of colours simulated lost dentin, transparent enamel shades enamel, and mammelon and clear transparent shades special effects. Reconstruction was performed in layer technique with the useof instruments for plasticizing including responding brushes and polymerization of each layer separately.

    MeSH:	TOOTH ABNORMALITIES
    Abstract:	Dens invaginatus is a developmental anomaly, manifested by insertion of enamel and dentin inside the crown and root. This aberration is revealed by the broad spectrum of morphological variations, from the foramen coecum to the smaller larger insertion in the root, sometimes extending to the very apex. Current anomaly classification, presented by Oehlers in 1957, divides the anomalyinto three categories. It is usually detected by roentgen examination. If there is a communication between the invagination and the pulp or a periradicular tissue, soon after tooth eruption change occurs in the pulp vitality in the form of affectation, necrosis and periapical pathological transformation wich necessitates urgent dental intervention. The treatment depends on the type of anomalyand its communication with the pulp and the periapical tissue. The purpose of the study was to present endodontic treatment possibility for the stated anomaly. A 20 yearold patient contacted the Department of Restorative Dentistry at the University of Zagreb school of Dental Medicine complaining of pain in the area of the upper right central incisor. Clinical examination determined palatalprotuberation and Y shape form of the palatal tooth surface including three foramens. Radiological examination showed class II invgination according to Oehlers with periapical communication and extensive periapical process. Endodontic treatment was performed simultaneously with enlargement of both invagination foramens as well as the central area inbetween. Distal root canal was C-shapedwhile the mesial was oval. Method of instrumentation was combined Profile and “step-back” techniqe. Working lenght of the root canal was verified using electronic device Endometer ES-03. Root canals were filled using thermoplastic techniqe and the control X-rays was made after the endodontic treatment. Finally, the crown wasesthetically reconstucted with composite resin. Follow through after one, three and six months revealed a reduction of the pathological process as well as disppearance of clinical symtoms.

    Abstract:	Amalgam has been used as a restorative material for 150 years. Mechanical loading can lead to dimensional changes resulting in marginal gaps and cracking of the hard dental tissue.The aim of this investigation was to locate and find out how often cracks happen with amalgam restorations. On order to determine this 30 examines were examined (21 male and 9 female), aged from 16 to 42 years. Clinical examination resulted in 23 out of 30 examined patients (159 teeth) had cracks. Cracks were drawn on formerlyprepared schemes. Results showed that: 1. 48% of cracks were in primary amalgam restorations; 2. cracks were localized buccally (31%) and distally-proximally (26%); 3. nearly half of all Black Class I and II restorations had cracks; 4. cracks were found in upper molars (75%) and especially in first ones (80%); 5. 61% of examines with cracks were distally-proximally; 6. There were no statisticallysignificant differences between male and female examines; 7. Frequency of cracking raises with age. Cracking is bound with properties of amalgam, influence of loading on amalgam restorations and other factors. This investigation lead us to conclude that every second patient with an amalgam restoration had a crack and better diagnosis and repairing is needed to prevent further cracking.

    MeSH:	DENTAL CARIES + prevention & control CHEWING GUM
    Abstract:	Dental caries, because of its spread worldwide, represents a public health problem. It is therefore, not surprising to find a great number of materials and procedures whose goal is the prevention of its formation. One such procedure is use of chewing gums which stimulate the secretion of saliva, thus preventing the formation of dental bacterial plaque on the surface of the teeth as well as a removal of existing plaque. The study included 16 students (12 female and 4 male) of the 3rd, 4th and 5th year of the Dental School of the Zagreb Universitiy. The goal was to measure the quantity of secretion of unstimulated saliva as opposed to that of stimulated saliva for each student, using the wax sticks borrowed from the Caries risk test set (Schaan, Vivadent) and two kinds of Orbit chewing gum (Wrigley: Winterfresh and Wild Strawberry). The examinees first chewed the wax and the chewing gum for one minute and then swallowed all the secreted saliva. Afterwards they chewed for another three minutes, this time collecting the secreted saliva into a calibrated measuring cup. The achived results are expressed as the medium value and standard deviation, the difference between them being noted with Student t-test. KEP index (DMF/t) for each examinee was also calculated. The achived results showed a significant difference in the saliva secretion during the use of chewing gum and the use of wax. There was also a difference in the secretion of saliva regarding the flavour of the chewing gum. The volume of saliva was more when Wild Strawberry was used. The results of the study justify the use of chewing gums, especially if we take into consideration that many of them contain an artificial sweetner, such as xylithol, with a strong anticaries effect.

    MeSH:	COMPOSITE RESINS
    Abstract:	Today available composite materials are polymerized by blue light, with a wavelength of about 468 nm. Commercially available curing units for composite resin polymerization emit blue light of different intensity. Using curing units of higher light intensity to reach a higher degree of conversion unavoidably leads to higher temperature rise in material during hardening, and also to polymerization shrinkage of material. The aim of this study was to determine if there is any difference between the degree of conversion and temperature rise in three composite materials: Amelogen (Akeda Dental, Denmark), Pertac II (ESPE, Seefeld, Germany) and Z100 (3M Dental Products, St. Paul, Minessotta, USA) polymerized with exponential program of Elipar Trilight curing unit (ESPE, Seefeld, Germany) and Lux-o-Max curing unit (Akeda Dental, Denmark) based on LED (light emitting diodes) technology. The results showed only a slightly lower degree of conversion, in the case of polymerization with Lux-o-Max curing unit. The temperature rise was significantly lower in the case of polymerization with Lux-o-Max curing unit for all tested composite materials.

    MeSH:	ADHESIVES DENTIN-BONDING AGENTS SENSITIVITY AND SPECIFICITY PAIN, POSTOPERATIVE
    Abstract:	Increasing requirements for the longevity of filling and marginal integration has influenced the development of new materials in restorative procedure on enamel and dentine. These requirements have contributed to the development of several generations of composite materials and dentine adhesives. Adhesion of the restorative material on the enamel is succesfully enhanced with the use of enamel adhesives, while bonding to dentine, because of its specific constitution and wetness of its surface, is not always acceptable and longlasting. The latest generation of dentine adhesives shows better bonding values, better sealing of the dentine surface and is simpler to handle than earlier generations of dentine adhesives. The aim of this study was to determine in 453 small medium and deep cavities the clinical existence of postrestorative sensitivity after the application of “Excite” one-bottle enamel-dentine adhesive under a composite resin filling one and three months after the application of the composite filling. After one month 21 teeth showed sensitivity of 1st, 2nd and 3th degree, and after three months only four teeth showed sensitivity of 1st and 2nd degree. This confirmed the fact that “Excite” enamel-dentine adhesive can successfully decrease the presence of postrestorative sensitivity.

    Abstract:	The aim of this study was to stress the importance of periodical removal of hard and soft sediments as well as of dental surface polishing. A clinical examination was performed among 18 fifth year students of the School of Dental Medicine, University of Zagreb. The use of Caries Risk Test (Vivadent, Schaan, Liechtenstein) showed the amount of Streptococcus mutans and Lactobacillus in the saliva. Based an the results obtained, we polished the teeth with Proxyt pastes for cleaning and polishing, each being of different abrasive value, determined by the producer and labelled as RDA (Relative Dentin Abrasion). After polishing the test was repeated. The results achieved were compared to data previously obtained and showed that dental surface polishing and removal of hard dental sediments have been neglected.

    Abstract:	The continual progress in development of new dental materials for tooth fillings and the presence of those materials on the market confuse the dentist when choosing the most appropriate material. The purpose of this research was to carry aut a survey in order to find out what are the most frequently used materials for permanent tooth fillings, dentine adhesives and polymerization units in clinical practice. The survey covered 304 subjects (doctors/dentists) with experience ranging from 1 to 40 years of practice. The results show that Tetric Ceram (Vivadent, Schaan, Liechtenstein) is the most used composite material, Syntac (Vivadent, Schaan, Liechtenstein) the most used dentine adhesive and Heliolux (Vivadent, Schaan, Liechtenstein) the most used curing unit for photopolymerisation of composite materials in clinical practice.
