AB  - Multidetector computed tomography (MDCT) is often necessary to manufacture 3D-printed medical models (MMs) required for mandibular restoration due to trauma or malignant tumor. Although cone-beam computed tomography (CBCT) is a preferable method of mandibular imaging, additional scanning is often unjustified. To test whether a single radiologic protocol could be used for mandibular reconstructions, the human mandible was scanned with 6 MDCT and 2 CBCT protocols and later 3D-printed using a fused-deposition modelling technique. Then, we assessed linear measures on the mandible and compared them with MDCT/CBCT digital scans and 3D-printed MMs. Our data revealed that CBCT0.25 was the most precise protocol for manufacturing 3D-printed mandibular MMs, which is expected considering its voxel size. However, we noted that CBCT0.35 and Dental2.0H60s MDCT protocols were of comparable accuracy, indicating that this MDCT protocol could be a single radiologic protocol used to scan both donor and recipient regions required for mandibular reconstruction.

AB  - Introduction: Open pores between endodontic sealer and root canal walls present potential niches for bacterial growth and migration pathways. The aim was to assess the internal and external porosity of calcium silicate-based sealers and to ascertain the long-term effect of storage in simulated body fluid on sealer porosity. Methods: Sixteen single-rooted teeth were filled with gutta-percha and 1 of 4 root canal sealers: BioRoot RCS, EndoSequence BC, MTA Fillapex, or AH Plus. Obturated roots, stored in Hank's balanced salt solution, were scanned after 7 days and after 6 months by using micro-computed tomography at an isotropic resolution of 9.9 mm. Total, open, and closed porosity were calculated in the coronal, middle, and apical thirds. Data were statistically analyzed by using general linear model and paired t test (alpha = 0.05). Results: Significantly higher percentage of open than closed porosity was found in all groups. Initially, significantly greater open and total porosity were found for MTA Fillapex than for AH Plus. After 6 months, the percentage of open and total porosity increased in BioRoot RCS and MTA Fillapex and decreased in AH Plus and EndoSequence BC. Both initially and after storage, coronal region of all sealers had significantly greater total porosity than middle and apical regions, which were comparable. Conclusions: None of the root fillings were void-free, with predominant open porosity persisting after long-term storage.

AB  - The aim of the present study was to develop a new method to reconstruct damaged metatarsophalangeal joint (MTPJ) of Homo naledi's fossil and to deepen the understanding of the first metatarsal head (FMH) morphological adaptation in different gait patterns. To this purpose three methods were introduced. The first served to compare the anthropometric linear and volumetric measurements of Homo naledi's MTPJ to that of 10 various athletes. The second was employed to measure curvature diameter in FMH's medial and lateral grooves for sesamoid bones. The third was used to determine the parallelism between medial and lateral FMH grooves. The anthropometric measurements of middle-distance runner to the greatest extent mimicked that of Homo naledi. Thus, it was used to successfully reconstruct the damaged Homo naledi's MTPJ. The highest curvature diameter of medial FMH groove was found in Homo naledi, while in lateral FMH groove it was the highest in volleyball player, suggesting their increased bear loading. The parallelism of medial and lateral FMH grooves was observed only in Homo naledi, while in investigated athletes it was dis-parallel. Athletes' dis-paralleled structures make first MTPJ simple flexion movement a complicated one: not rotating about one axis, but about many, which may result in bringing a negative effect on running. In conclusion, the presented method for the reconstruction of the damaged foot bone paves the way for morphological and structural analysis of modern population and fossil hominins' gait pattern.

AB  - Dental cement materials have been developed with the aim to replace hard dental tissues. The first material used for pulp capping, root canal obturation, bifurcation perforation and apexification is calcium hydroxide (in 1920). A half century later, glass-ionomer cements began to suppress it as dentine substitutes. Finally, in the 1990s, calcium silicate (CS) material appeared in the dental research community as the most promising dentine substitute capable to adequately meet all clinical requirements. The aim of this paper is to present an overview of literature related to studies about CS materials taking into account their physical, chemical and biological properties and clinical applications. This review aims to discuss beneficial and adverse characteristics of CSs concerning interactions to the hard dentine and soft pulp/periodontal tissues. This review article deals with the literature data about currently commercially available CS concerning laboratory and clinical findings. 109 scientific articles were analyzed of which 62 references reported in vitro and 26 in vivo investigations while 21 references comprised reports, reviews and books dealing with both, in vitro and in vivo investigations. Although further data collection is necessary, CSs are promising materials that represent a gold standard for numerous dental clinical procedures.

AB  - Background. The authors investigated morphologic parameters of the palatal cortex that affect the diffusion of local anesthetic solution in the region of the anterior middle superior alveolar (AMSA) nerve block injection site. Methods. The authors used computed tomographic (CT) and micro-CT imaging to assess 20 human skulls from an anatomic collection. Analysis of the C1 images included frequency, distribution, and width of the nutrient canals in the bony palate, according to to the person's sex and age. Micro-CT analysis involved measuring the thickness and porosity of palatal cortical bone in the area of the AMSA injection site in relation to the thickness and porosity of the opposite buccal cortical bone. Results. There was a statistically significant difference (P = .042) in the location of the nutrient canals between male specimens (> 50% in the border region) and female specimens (> 50% in the palatal process). Furthermore, the female skulls had significantly wider nutrient canal foramina (P = .042) than did the male skulls. Despite greater thickness, the palatal cortex in the area of the AMSA injection site had slightly greater porosity than did the buccal cortex. A significantly greater number of microcanals penetrated the whole cortical thickness in palatal than in buccal cortical bone (P = .001). Conclusions. The distribution and width of nutrient canals differed between male and female skulls. At the microscopic level, structural characteristics of the palatal cortex provide a good anatomic basis for the potential of a satisfactory AMSA injection success rate. Practical Implications. The AMSA technique success rate might be increased if the clinician adjusts the injection site to the distribution of nutrient canals, depending on the sex of the patient.

AB  - Introduction: The outcome of periapical surgery has been directly improved with the introduction of novel material formulations. The aim of the study was to compare the retrograde obturation quality of the following materials: calcium silicate (Biodentine; Septodont, Saint-Maur-des-Fosses, France), mineral trioxide aggregate (MTA+; Cerkamed Company, Stalowa Wola, Poland), and glass ionomer cement (Fuji IX; GC Corporation, Tokyo, Japan). Methods: Materials' wettability was calculated concerning the contact angles of the cements measured using a glycerol drop. Cements' porosity was determined using mercury intrusion porosimetry and micro computed tomographic (mu CT) imaging. Extracted upper human incisors were retrofilled, and mu CT analysis was applied to calculate the volume of the gap between the retrograde filling material and root canal dentin. Experiments were performed before and after soaking the materials in simulated body fluid (SBF). Results: No statistically significant differences were found among the contact angles of the studied materials after being soaked in SBF. The material with the lowest nanoporosity (Fuji IX: 2.99% and 4.17% before and after SBF, respectively) showed the highest values of microporosity (4.2% and 3.1% before and after SBF, respectively). Biodentine had the lowest value of microporosity (1.2% and 0.8% before and after SBF, respectively) and the lowest value of microgap to the root canal wall ([10 +/- 30] x 10(-3) mm(3)). Conclusions: Biodentine and MTA possess certain advantages over Fuji IX for hermetic obturation of retrograde root canals. Biodentine shows a tendency toward the lowest marginal gap at the cement-to-dentin interface.

AB  - Stem cells have shown great potential for in vitro tissue engineering, regenerative medicine, cell therapy and pharmaceutical applications. All these applications, especially in clinical trials, will require guided production of high-quality cells. Traditional culture techniques and applications have been performed for the majority of primary and established cell lines and standardized for various analyses. Still, these culture conditions are unable to mimic dynamic and specialized three-dimensional microenvironment of the stem cells' niche from in vivo conditions. In an attempt to provide biomimetic microenvironments for stem cells in vitro growth, three-dimensional culture techniques have been developed. In our study advantages of newly developed porous scaffolds as the most promising in vitro imitation of niche that provides physical support, enables cell growth, regeneration and neovascularization, while they are replaced in time with newly created tissue was explained. Furthermore, dynamic cultivation techniques have been described, as new way of cell culturing that will be the main subject of our future research. In that manner, by developing an optimal dynamic culturing method, high-quality new cells and tissues would be possible to obtain, for any future clinical application.

AB  - This study examined the potential of a new porous calcium hydroxyapatite scaffold covered with poly (lactide-co-glycolide) (PLGA) as a bone substitute, identifying its advantages over Geistlich Bio-Oss (R), considered the gold standard, in in vivo biofunctionality investigations. Structural and morphological properties of the new scaffold were analyzed by scanning electron and atomic force microscopy. The biofunctionality assays were performed on New Zealand white rabbits using new scaffold for filling full-thickness defects of critical size. The evaluated parameters were: the presence of macrophages, giant cells, monoocytes, plasma cells, granulocytes, neo-angiogenesis, fibroplasia, and the percentage of mineralization. Parallel biofunctionality assays were performed using Geistlich Bio-Oss (R). The appearance of bone defects 12 weeks after the new scaffold implantation showed the presence of a small number of typical immune response cells. Furthermore, significantly reduced number of capillary buds, low intensity of fibroplasia and high degree of mineralization in a lamellar pattern indicated that the inflammation process has been almost completely overcome and that the new bone formed was in the final phase of remodeling. All biofunctionality assays proved the new scaffold's suitability as a bone substitute for applications in maxillofacial surgery. It showed numerous biological advantages over Geistlich Bio-Oss (R) which was reflected mainly as a lower number of giant cells surrounding implanted material and higher degree of mineralization in new formed bone.

AB  - There is growing need for synthetic tissue replacement materials designed in a way that mimic complex structure of tissues and organs. Among various methods for fabrication of implants (scaffolds), 3D printing is very powerful technique because it enables creation of scaffolds with complex internal structures and high resolution, based on medical data sets. This method allows fabrication of scaffolds with desired macro- and micro-porosity and fully inter- connected pore network. Rapid development of 3D printing technologies has enabled various applications from the creation of anatomical training models for complex surgical procedures to the printing of tissue engineering constructs. The aim of current investigations was to develop compatible printers and materials (bioinks) to obtain biomimetic scaffolds, which allow printing of living cells without significant loss of cell viability. The advanced level of such printing assumes “in situ” printing, i.e. printing cells and biomaterials directly onto or in a patient that will reduce recovery time.

AB  - The objective of this study was to determine the effects of various irrigation solutions on root canal dentine and gutta-percha surface properties. In addition, the effects of disinfectant chemicals on the wettability and surface morphological properties of the filling materials were evaluated. Ethylenediaminetetraacetic acid (EDTA), citric acid, and ozone were employed as irrigation solutions for dentine and gutta-percha treatment. Thereafter, the samples' microstructure, degree of mineralization, and mechanical properties were assessed by means of quantitative backscattered electron imaging (qBEI) and reference point indentation (RN). A contact angle analyzer was used to measure adhesion on the tested materials. Here, EDTA had the most significant affect on both the mechanical properties and the adhesive behavior of dentine. Citric acid did not affect dentine wettability, whereas the indentation properties and the mineralization were reduced. Similar effects were observed when ozone was used. The dentinal tubules were significantly widened in citric acid compared to the ozone group. EDTA causes considerable micromechanical surface alteration of dentine and gutta-percha, but represents the best option in clinical cases where a high adhesiveness of the filling materials is desired.

AB  - Bacground/Aim. The radiopacity of an endodontic material can considerably vary as measured on film and a digital sensor. Digital radiography offers numerous advantages over convential film-based radiography in dental clinical practice regarding both diagnostic capabilities and postintervention procedures. The aim of this study was to investigate the capacity of conventional and charge-conpled device (CCD) based digital radiography to detect material on radiograph depending on the radio-pacifying agent present in the material. Methods. Experimental cements were formulated by mixing Portland cement with the following radiopacifying agents: zinc oxide (ZnO), zirconium oxide (ZrO2), titanium dioxide (TiO2), barium sulphate (BaSO4), iodoform (CHI3), bismuth oxide (Bi2O3) and ytterbium trifluoride (YbF3). In addition, 5 endodontic materials comprising Endomethasone®, Diaket®, N2®, Roth 801® and Acroseal® were investigated to serve as control. Per three specimens of each material were radiographed alongside an aluminum step wedge on film (Eastman Kodak Company®, Rochester, NY) and a CCD-based digital sensor (Trophy Radiologie®, Cedex, France). Radiopacity values were calculated by converting the radiographic densities of the specimens expressed as a mean optical densities or mean grey scale values into equivalent thickness of aluminum. Results. Twoway ANOVA detected no significant differences with respect to the imaging system (p > 0.05), but the differences were significant with respect to radiopacifier (p  lt  0.001) and the interaction of the two factors (p  lt  0.05). Paired ttest revealed significant differences between the methods used for pure Portland cement, all concentrations of BaSO4 and CHI3, 10% and 20% additions of ZrO2 and Bi2O3 and 10% and 30% addition of YbF3 (p  lt  0.05). Conclusion. The materials which incorporate CHI3 or BaSO4 as radiopacifying agents are expected to be significantly more radiopaque on a digital sensor than on film. During clinical practice one should concern to the quality of contrast assessement obtained by digital according to conventional radiography.

abstract = "Bacground/Aim. The radiopacity of an endodontic material can considerably vary as measured on film and a digital sensor. Digital radiography offers numerous advantages over convential film-based radiography in dental clinical practice regarding both diagnostic capabilities and postintervention procedures. The aim of this study was to investigate the capacity of conventional and charge-conpled device (CCD) based digital radiography to detect material on radiograph depending on the radio-pacifying agent present in the material. Methods. Experimental cements were formulated by mixing Portland cement with the following radiopacifying agents: zinc oxide (ZnO), zirconium oxide (ZrO2), titanium dioxide (TiO2), barium sulphate (BaSO4), iodoform (CHI3), bismuth oxide (Bi2O3) and ytterbium trifluoride (YbF3). In addition, 5 endodontic materials comprising Endomethasone®, Diaket®, N2®, Roth 801® and Acroseal® were investigated to serve as control. Per three specimens of each material were radiographed alongside an aluminum step wedge on film (Eastman Kodak Company®, Rochester, NY) and a CCD-based digital sensor (Trophy Radiologie®, Cedex, France). Radiopacity values were calculated by converting the radiographic densities of the specimens expressed as a mean optical densities or mean grey scale values into equivalent thickness of aluminum. Results. Twoway ANOVA detected no significant differences with respect to the imaging system (p > 0.05), but the differences were significant with respect to radiopacifier (p  lt  0.001) and the interaction of the two factors (p  lt  0.05). Paired ttest revealed significant differences between the methods used for pure Portland cement, all concentrations of BaSO4 and CHI3, 10% and 20% additions of ZrO2 and Bi2O3 and 10% and 30% addition of YbF3 (p  lt  0.05). Conclusion. The materials which incorporate CHI3 or BaSO4 as radiopacifying agents are expected to be significantly more radiopaque on a digital sensor than on film. During clinical practice one should concern to the quality of contrast assessement obtained by digital according to conventional radiography., Uvod/Cilj.

AB  - Introduction Antioxidants protect against reactive oxygen species and expose beneficial anti-inflammatory activity when in contact with biological tissues. Dental materials that are used as temporary luting on fixed dental restorations are often in contact with injured gingival tissue, hence they should contain anti-inflammatory characteristics that are essential after prosthetic procedures preceding cementation of final restauration. Objective The aim of this study was to investigate the antioxidant effect through the oxidation inhibition (OI) of mixed dental cement for temporary luting or their liquid component. Methods Eight study groups were prepared each by ten samples: 1) ex tempore preparation of zinc-oxide eugenol paste (Kariofil Z Galenika, Serbia), 2) Viko Temp paste (Galenika, Serbia), 3) Temp Bond NE paste (Kerr, Germany), 4) ScutaBond (ESPE, Germany), 5) Cp-CAP paste (Germany, Lege Artis) and oil component of 6) Kariofil Z, 7) Viko Temp and 8) Cp-CAP. The samples were subjected to spectrophotometer to measure OI 2,2'-azino-di-(3-ethyl-benzthiazoline-6-sulphonic acid) (ABTS) using Randox kit, United Kingdom. The control samples were pure ascorbic acid (1% w/v). Results High values of OI exposed materials (groups 1, 5, 6, 7, 8) with content of eugenol (or its derivates) in the range of 100-88.8% were statistically more significant than the values of non-eugenol substances (groups 2, 3, 4) with the range of 8.2-43.5%. Conclusion Eugenol containing temporary fixation materials show significant antioxidative properties and therefore they may be used in those clinical situations where surrounding gingival tissue is injured during restorative procedure.
AB  - Uvod Antioksidansi štite živa tkiva od reaktivnih kiseonikovih slobodnih radikala, čime ispoljavaju poželjno antiinflamatorno dejstvo u kontaktu sa živim tkivom. Stomatološki materijali koji služe za privremeno cementiranje protetičkih restauracija često su u kontaktu s lediranim tkivom gingive, pa stoga treba da poseduju poželjne antiinflamatorne osobine, vrlo bitne nakon protetičkih procedura koje prethode cementiranju fiksnih restauracija. Cilj rada Cilj ispitivanja je bio da se pomoću zabeleženih vrednosti inhibicije oksidacije (IO) utvrdi antioksidativni efekat nekoliko pripremljenih preparata za privremeno cementiranje i njihovih tečnih komponenata. Metode rada Po deset uzoraka je pripremljeno u osam eksperimentalnih grupa: 1) ex tempore zamešana cink-oksidna (ZnO) eugenol pasta (Kariofil Z Galenika, Srbija); 2) pasta Viko Temp (Galenika, Srbija); 3) pasta Temp Bond NE (Kerr, Nemačka); 4) pasta ScutaBond (ESPE, Nemačka); i 5) pasta Cp-CAP (Lege Artis, Nemačka); njihove tečne komponente: 6) ulje Kariofil Z; 7) ulje Viko Temp; i 8) ulje Cp-CAP. Uzorci su podvrgnuti spektrofotometru radi merenja vrednosti IO na ABTS primenom seta reagensa (Randox kit, Velika Britanija). Kontrolnu grupu su činili uzorci čiste askorbinske kiseline (1% w/v). Rezultati Visoke vrednosti IO ispoljili su uzorci u grupama eugenolnih materijala 1, 5, 6, 7 i 8 u rasponu od 88,8% do 100%, što je bilo statistički značajno u odnosu na niže vrednosti kod neeugenolnih materijala (raspon 8,2-43,5%) u grupama 2, 3 i 4. Zaključak Nije zabeležena statistička značajna razlika u vrednostima IO međusobnim poređenjem eugenolnih grupa (p>0,05). Poređenjem vrednosti IO između neeugenolnih grupa, samo je kod grupe 4 utvrđena statistički značajna razlika prema grupama 2 i 3 (p lt 0,01). Poređenjem uzoraka 2 i 3 zabeležena je statistički beznačajna razlika za vrednosti IO (p>0,05).

AB  - Purpose: The aim of this in vitro study was to investigate the potential of digital and conventional radiography to detect small amounts of residual dental luting cements around implant abutments. Materials and Methods: Artificial cement and aluminum overhangs in varying thicknesses, heights, and depths were radiographed adjacent to implant restorations with a radiovisiography sensor. Five trained evaluators were asked to identify the smallest depth of overhang that could be detected on radiographs. Results: For detection of cement overhangs adjacent to implant abutments, a luting agent must have greater radiopacity than what is recommended by relevant International Organization for Standardization directives. To detect a 0.1-mm-thick portion of excess cement adjacent to an implant abutment, the cement should have a radiopacity of at least 1.7 mm of aluminum for high-resolution digital radiographs and 2.2 mm of aluminum for film-based radiographs. Two-way analysis of variance revealed that the thickness of the specimens, type of imaging detector, and type of cement all affected the radiopacity threshold for artificial cement excess (P  lt  .05). The height of the specimens and the surrounding structures were not statistically significant factors in cement detection. Conclusions: Digital radiography offers better possibilities for visualization of cement excess than conventional radiography.

AB  - This article presents a literature review on the resin bond to zirconia ceramic. Modern esthetic dentistry has highly recognized zirconia, among other ceramic materials. Biocompatibility of zirconia, chemical and dimensional stability, excellent mechanical properties, all together could guarantee optimal therapeutical results in complex prosthodontic reconstruction. On the other hand, low thermal degradation, aging of zirconia as well as problematic bonding of zirconia framework to dental luting cements and tooth structures, opened the room for discussion concerning their clinical durability. The well known methods of mechanical and chemical bonding used on glass-ceramics are not applicable for use with zirconia. Therefore, under critical clinical situations, selection of the bonding mechanism should be focused on two important points: high initial bond strength value and long term bond strength between zirconia-resin interface. Also, this paper emphases the use of phosphate monomer luting cements on freshly air-abraded zirconia as the simplest and most effective way for zirconia cementation procedure today.
AB  - Rad daje osvrt na problem vezivanja nadoknada od cirkonijum-dioksida za zubna tkiva. Cirkonijum-dioksid (cirkonija) je oksidni keramički materijal koji u stomatologiji - posebno u savremenoj estetskoj praksi-nalazi važno mesto. Dobrih mehaničkih karakteristika, visoke biokompatibilnosti i zadovoljavajućih optičkih osobina, on predstavlja materijal izbora u velikom broju protetičkih indikacija. Ono što može ugroziti krajnje terapijske rezultate kada je u pitanju klinička eksploatacija nadoknada od cirkonijum-dioksida jeste nemogućnost jednoobrazne pripreme njene površine za vezivanje s različitim cementima i zubnim strukturama. U radu se opisuju i diskutuju različiti načini pripreme povr- šine cirkonije. Naglašava se da u odabiru optimalne metode prednost treba dati jednostavnijim kliničkim opcijama, poput peskiranja površine cirkonije i upotrebe kompozitnog cementa sa specijalnim fosfatnim monomerima.

Dobrih mehaničkih karakteristika, visoke biokompatibilnosti i zadovoljavajućih optičkih osobina, on predstavlja materijal izbora u velikom broju protetičkih indikacija. Ono što može ugroziti krajnje terapijske rezultate kada je u pitanju klinička eksploatacija nadoknada od cirkonijum-dioksida jeste nemogućnost jednoobrazne pripreme njene površine za vezivanje s različitim cementima i zubnim strukturama. U radu se opisuju i diskutuju različiti načini pripreme povr- šine cirkonije. Naglašava se da u odabiru optimalne metode prednost treba dati jednostavnijim kliničkim opcijama, poput peskiranja površine cirkonije i upotrebe kompozitnog cementa sa specijalnim fosfatnim monomerima.",

AB  - Objective: According to the ISO, the radiopacity of luting cements should be equal to or greater than that of aluminum. The aim of this in vitro study was to determine the radiopacity of 13 commercially available dental luting cements and compare them with human enamel and dentin. Method and Materials: Five classes of luting cements were evaluated: zine phosphate (Cegal N and Harvard Zine Phosphate), zine polycarboxylate (Harvard Polycarboxylate and Hoffmann's Carboxylate), glass ionomers (Ketac Cem Fasymix, Ketac Cem Radiopaque, and Fuji I), resin-modified glass ionomer (Rely X Luting), and resin cements (Multilink Automix, Variolink II, Speed CEM, Rely X Unicem Automix, and three shades of Variolink Veneer). Tooth slices served as controls. Five specimens of each material measuring 8 mm in diameter and 1 mm thick were prepared and radiographed alongside tooth slices and an aluminum stepwedge using a Trophy RVG sensor. The radiopacity values were expressed in mm Al and analyzd by the ANOVA and Tukey tests (P  lt  .05). Results: All the cements examined except Variolink Veneer had significantly higher radiopacities than that of dentin. Rely X Unicem Automix, glass ionomer, and resin-modified glass-ionomer cements demonstrated radiopacities that were not significantly different with respect to enamel. Zinc phosphate, zinc polycarboxylate, and three of the resin cements presented radiopacity values that were significantly greater than that of enamel. Conclusion: Almost all the investigated materials presented an acceptable radiopacity. Radiopacity of dental cements seems to depend more on the presence of elements with high atomic numbers than on the type of the material. (Quintessence Int 2012; 43: 421-428)

AB  - Objectives. According to the International Standard Organization (ISO), the radiopacity of luting cements and dental posts should be equal to or greater than that of aluminum. The aims of these in vitro studies were: to determine the radiopacity of 13 commercially available dental luting cements and compare it with that of human enamel and dentin, to investigate the capacity of various radiopacifying agents to produce the difference in radiopacity on film and a CCD - based digital sensor, to evaluate the radiopacity of seven commercially available dental posts and determine the minimum radiopacity value necessitated for their clinical evaluation and to determine the threshold radiopacity value for detection of small thicknesses of dental luting cements in adjacent to implant abutment. Materials and Methods. Five classes of luting cements were evaluated: zinc phosphate (Cegal N and Harvard Zinc Phosphate), zinc polycarboxylate (Harvard Polycarboxylate and Hoffmann’s Carboxylate), glass ionomers (Ketac Cem Easymix, Ketac Cem Radiopaque and Fuji I), resin-modified glass ionomer (Rely X Luting), and resin cements (Multilink Automix, Variolink II, Speed CEM, Rely X Unicem Automix and Variolink Veneer). Teeth slices served as controls. Five specimens of each material measuring 8 mm in diameter and 1 mm thick were prepared and radiographed alongside tooth slices and an aluminum stepwedge using a Trophy Radiovisiography (RVG) sensor (Trophy Radiology, Cedex, France). The radiopacity values were expressed in mm Al and analyzed by the ANOVA and Tukey tests (P  lt  0,05). For determination of radiographic system capacity to detect material's radiopacity depending on the radiopacifier present within experimental cements were formulated by mixing metacrylate with the following radiopacifying agents: zinc oxide (ZnO), zirconium oxide (ZrO2), titanium dioxide (TiO2), barium sulphate (BaSO4), iodoform (CHI3), bismuth oxide (Bi2O3) and ytterbium trifluoride (YbF3). Five specimens of each material were radiographed alongside an aluminum stepwedge on E speed film (Eastman Kodak Company, Rochester, NY) and a CCD - based digital sensor (Trophy Radiology). Radiopacity values were calculated by converting the radiographic densities of the specimens expressed as a mean optical densities or mean grey scale values into equivalent thickness of aluminum...
