AB  - Research of nonthermal atmospheric plasma (NTAP) for dental applications has been increasing in recent years. This paper presents a literature review of potential use of NTAP for treatment of surfaces of dental materials and hard dental tissues. The aim of NTAP interaction with dental materials and tissues is surface modification for stable and durable material-to-material or material-to-tissue bonds. Reactive particles in NTAP and various mixtures of gasses increase hydrophilicity of material surface, which is known to be hydrophobic in implants, ceramics or dental composites, with or without roughness changes. Adhesion of cells to implant surface was shown to improve after NTAP treatment, thereby promoting successful osseointegration. Bonding ceramic materials to the prepared surfaces of teeth or fiber/metal posts was shown to improve after NTAP treatment. Hard dental tissues achieve primarily micromechanical bonds with composite materials using dental adhesives. Increased organic content in the form of collagen fibrils and residual water pose a problem for achieving adequate and long-term adhesive-dentin bonds. This problem has not been solved with current adhesive application protocols. It was recently shown that application of NTAP improves the hydrophilicity of dentin surface and changes its polarity, which can contribute to better distribution of adhesive resin and deeper penetration into the hybrid layer. Previous studies pointed to similar or better initial adhesive bonds with dentin. However, adhesive-dentin bonds are subject to degradation in the long-term also after NTAP treatment suggesting the need for further optimization of NTAP for application on dentin.

AB  - Objective To determine color changes in bulk-fill composite and universal composite restorations with dissimilar dentin replacement materials in extracted teeth after staining in red wine. Materials and Methods Cylindrical, 4 mm deep, class I cavities were prepared in 140 human molars. Bottom 2 mm was restored with Biodentine (Septodont), everX posterior (GC) or experimental HAP inserts. Each dentin replacement material was covered with a 2-mm layer of a universal composite Filtek Z250 or Z550 (3M ESPE) or Gradia Posterior (GC). Groups combining top composite layer and the underlying dentin replacement were designated as "composite_dentin replacement." Filtek Bulk Fill (3M ESPE) and Tetric EvoCeram Bulk Fill (Ivoclar Vivadent) were placed as a single 4-mm layer. Color measurements were performed using Vita Easyshade 4.0 (Vita Zahnfabrik) initially and after 48-hours storage in red wine at 37 degrees C. Results Color differences (Delta E-oo) ranged between 2.1 +/- 0.7 (Z250_HAP) and 7.8 +/- 1.1 (Z550_everX). EverX resulted in higher Delta E-oo of the overlying composite than HAP (P  lt  .001) and Biodentine (P = .006). Generally, Delta E-oo was affected more by decreasing lightness (Delta L ') than changes in chroma (Delta C '). Conclusions EverX resulted in higher Delta E-oo of the restoration than Biodentine and experimental HAP after staining in red wine. No significant differences in Delta E-oo may be expected in different composites with the same underlying dentin replacement material. The same was generally true for bulk-fill and universal composites. Clinical Significance Similar extent of color changes may be expected in bulk-fill and universal composites. Highly translucent everX might exhibit greater color differences irrespective of the capping composite than non-translucent materials. Clinicians have a wider choice of composite materials to cover a particular dentin replacement material, for example, everX or Biodentine, as similar color differences may be expected in various overlying composite brands.

AB  - The objective of this study was to measure temperature changes in the pulp chamber induced by polymerization of resin-based dental restoratives following a simulated procedure of direct pulp capping. Class I cavities with a microperforation at the pulp horn were prepared in extracted human molar teeth. The complete procedure of direct pulp capping and cavity restoration was performed with the root part of extracted teeth fixed in a water bath at 37 degrees C. Mineral trioxide aggregate, bioactive dentin substitute or calcium-hydroxide paste were used as pulp capping materials. Cavities were restored with a light-cured or chemically-cured resin-modified glass ionomer, universal adhesive and a bulk-fill composite, cured with a high-intensity LED unit. Pulp capping materials caused a slight temperature decrease. Lower temperature increase was recorded during light-curing of the glass ionomer liner after direct capping with mineral trioxide aggregate and calcium-hydroxide than that recorded for the bioactive dentin substitute. Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5 degrees C.

AB  - Introduction To obtain the ideal aesthetics, each restorative material must imitate natural tooth in color, surface texture and be stable over time. Damage or wear of the material causes poor optical properties of the restoration, so it is necessary to repolish, repair or replace it. The aim of this study was to test the gloss and surface changes of the composite materials with filler's particles of different size, before and after material artificial mechanical ageing. Material and Methods Four composite materials were tested, two microhybrid composites (Gradia Direct GC, Herculite XRV, Kerr) and two nanohybrid composites (Filtek Ultimate 3M; TetricEvoceram, Ivoclar). Composites' samples of 9 × 9 × 2 mm in size were polished in accordance to the standard protocol by Sof-Lex discs (2382 C, SM, F, SF) for 30 seconds. Gloss was measured after polishing and taking photos using optical microscope (400×). In the chewing simulator, ageing of the samples was conducted (100,000 cyclic kicks). After the samples' ageing, surface photos were taken and gloss measured. The obtained results were statistically processed (One-way ANOVA, t-test). Results The best gloss after polishing was shown by Filtek Ultimate (54.00 ± 14.06), the worst by Gradia Direct (47.33 ± 7.92). There was no statistically significant difference (p > 0.05) in surface gloss after polishing composite. The smallest defects on the surface of composites were detected in material Gradia Direct (21363.7 mm2 ) with the average value of the diameter 137 mm. Conclusion The tested nanohybrid and microhybrid composites showed comparable gloss value before and after artificial aging. Mechanical aging caused vivid changes regarding surface defects on all tested composite materials.
AB  - Uvod Da bi se dobila idealna estetika, svaki restaurativni materijal mora oponašati prirodni zub po boji i teksturi površine i mora biti stabilan u vremenu.

Cilj rada je bio da se ispitaju sjaj i površinske promene kompozita sa različitom veličinom čestica punilaca, pre i posle artificijalnog mehaničkog starenja.

U simulatoru žvakanja uzorci su izloženi artificijalnom starenju sa 100.000 cikličnih udaraca. Posle mehaničkog starenja ponovo je izmeren sjaj, a površine su fotografisane i sačuvane u digitalnom formatu. Dobijeni rezultati su statistički obrađeni (One-way ANOVA, t-test). Rezultati Najveći sjaj posle poliranja pokazao je Filtek Ultimate (54,00 ± 14,06), a najmanji Gradia Direct (47,33 ± 7,92). Nije bilo statistički značajne razlike sjaja između testiranih materijala posle poliranja (p > 0,05). Najmanji defekti na površini kompozita uočeni su kod materijala Gradia Direct (21.364 mm), sa srednjom vrednošću prečnika 137 mm.

AB  - ObjectivesThe study aims to evaluate the effects of non-thermal atmospheric plasma (NTAP) treatments on dentin wetting and surface free energy (SFE) and compare the effects of NTAP treatment, etch-and-rinse, and self-etch protocols for application of universal adhesives.Materials and methodsMid-coronal dentin of intact third molars was used to measure contact angles of distilled water, ethylene-glycol, and diiodomethane and calculate SFE following different NTAP preset treatments (feeding gas consisting of pure He, He + 1% O-2, He + 1.5% O-2), power input (1 or 3W), and tip-to-surface distance (2, 4, or 8mm). Contact angles of reference liquids and SFE of dentin following He + 1.5% O-2 at 3-W and 4-mm treatment was compared to phosphoric acid etching. Contact angles of Single Bond Universal (SBU; 3M ESPE) and Clearfil Universal Bond (CUB; Kuraray Noritake) were measured following NTAP, etch-and-rinse, and self-etch protocols.ResultsNTAP significantly reduced contact angles of reference liquids and increased dentin SFE compared to untreated dentin (p lt 0.05). O-2 intensified the effect of He NTAP (p lt 0.05). NTAP and phosphoric acid increased dentin polarity and Lewis base surface characteristics. Phosphoric acid increased contact angles of adhesives compared to the self-etch protocol (p lt 0.05).

AB  - Introduction Calcium hydroxide (CH) is a medicament widely used in endodontic treatment due to its antibacterial, regenerative and biocompatible properties. Studies have shown that remaining CH on root canal walls and dentinal tubules can compromise sealer penetration, leading to its weak adhesion, volume change and, consequently, apical leakage. The aim of this study was to compare the efficacy of four different techniques in removing calcium hydroxide from the root canal. Material and Methods 32 extracted single-rooted teeth with one canal were used in this study. The canals were prepared using BioRaCe system (FKG Dentaire, Swiss) BR5 40/.04 with sodium hypochlorite irrigation after each instrument. Longitudinal grooves were formed on the proximal root surfaces. All canals (except negative control) were filled with aqueous CH suspension. After seven days of incubation, the teeth were allocated into the four groups (n=7), plus positive and negative control. Four techniques (systems) for CH removal were tested: conventional syringe irrigation (CSI), passive ultrasonic irrigation (PUI), XP-endo Finisher (FKG Dentaire, Swiss) and Canal Brush (Roeko, Coltene) with irrigation of 5 ml 2% NaOCl and 5 ml 10% citric acid. All the roots were then split into the two halves with chisel and observed under the stereomicroscope (Boeco, Germany) at magnification of 20x. The area with remaining CH on the root canal wall surface was then divided with the total root canal surface area (%). The obtained results were statistically processed using One-way ANOVA and Tukey post-hoc test (p lt 0.05). Results The most efficient system was XP-endo Finisher with 91.33% of clean surface, followed by PUI 88.36%, Canal Brush 87.83%, and CSI with 66.92%. Conclusion None of the systems completely removed the traces of the medicament from the root canal. For optimal clinical success, it is necessary to combine various systems with copious irrigation.
AB  - Uvod Kalcijum-hidroksid (CH) predstavlja medikament koji se u velikoj meri koristi u endodontskoj terapiji zbog svojih antibakterijskih, regenerativnih i biokompatibilnih svojstava. Istraživanja pokazuju da ostaci CH na dentinskim zidovima i u tubulima mogu kompromitovati prodor silera, što doprinosi njegovoj lošijoj adheziji, promeni volumena, a samim tim i apeksnom curenju. Cilj rada je bio da se uporedi efikasnost četiri različite tehnike uklanjanja kalcijum-hidroksida iz kanala korena zuba. Materijal i metode Korišćena su 32 ekstrahovana jednokorena zuba sa jednim kanalom. Kanali su mašinski obrađeni BioRaCe sistemom (FKG Dentaire, Swiss) BR5 40/.04 uz irigaciju natrijum-hipohloritom posle svakog instrumenta. Na aproksimalnim površinama korenova napravljeni su uzdužni žlebovi. Svi kanali (osim negativne kontrole) napunjeni su vodenom suspenzijom CH. Posle sedam dana u inkubatoru, zubi su podeljeni u četiri grupe (n = 7), uz pozitivnu i negativnu kontrolu. Testirane su četiri tehnike (sistema) za ukljanjanje CH iz kanala korena: konvencionalna irigacija špricem (CSI), pasivna ultrazvučna irigacija (PUI), XP-endo Finisher (FKG Dentaire, Swiss) i Canal Brush (Roeko, Coltene), uz irigaciju 5 ml 2% NaOCl i 5 ml 10% limunskom kiselinom. Svi korenovi su dletom podeljeni na dve polovine i posmatrani pod stereomikroskopom (Boeco, Germany) na uveličanju od 20×. Od vrednosti ukupne površine kanala korena oduzimane su vrednosti neočišćene površine (%). Dobijene vrednosti su statistički obrađene oneway ANOVA i Tukey post hoc testom (p  lt  0,05). Rezultati Najefikasniji sistem bio je XP-endo Finisher sa 91,33%, zatim PUI sa 88,36%, Canal Brush sa 87,83%, i konvencionalna irigacija špricem sa 66,92% očišćene površine kanala korena. Zaključak Nijedan sistem nije u potpunosti uklonio tragove medikamenta iz kanala korena. Za potpuni klinički uspeh neophodno je kombinovati više sistema uz obilnu irigaciju.

AB  - Objectives. To evaluate optical properties (color and translucency) of 'sandwich' restorations of resin-based composites and esthetically unfavorable dentin restoratives. Methods. Cylindrical 'dentin' specimens (8 mm in diameter and 2 mm thick, N = 5/group) were prepared using EverX Posterior (GC), Biodentine (Septodont), experimental hydroxyapatite (HAP) or conventional composites (Gradia Direct Posterior, GC; Filtek Z250 and Filtek Z500, 3M ESPE). Capping 'enamel' layers were prepared using composites (Gradia Direct Posterior, Filtek Z250 or Z550) of Al or A3 shade and the following thickness: 0.6, 1 or 2 mm. Color (Delta E) and translucency parameter (TP) were determined using a spectrophotometer (VITA Easyshade Advance 4.0, VITA Zahnfabrik). Data were statistically analyzed using analysis of variance with Tukey's post-hoc tests (alpha = 0.05). Results. TP was greatly affected by layer thickness, whilst Delta E depended on shade and layer thickness of the capping composite. HAP and Biodentine showed significantly lower TP and higher Delta E (deviation from 'ideal white') than composites (p  lt  0.05). Greater TP was seen in EverX_composite groups than in corresponding control groups of the same shade and thickness. TP of composites combined with Biodentine or HAP was below 2, lower than the corresponding control groups (p  lt  0.05). Within-group differences of Delta E were greatest in HAP_composite groups. EverX_Gradia and EverX_FiltekZ250 combinations showed the most comparable Delta E with the control groups. Significance. A 2 mm thick layer of composite covering dentin restoratives with unfavorable esthetics is recommended for a final 'sandwich' restoration that is esthetically comparable to a conventional, mono-composite control restoration.

AB  - Objectives. To evaluate optical properties (color and translucency) of 'sandwich' restorations of resin-based composites and esthetically unfavorable dentin restoratives. Methods. Cylindrical 'dentin' specimens (8 mm in diameter and 2 mm thick, N = 5/group) were prepared using EverX Posterior (GC), Biodentine (Septodont), experimental hydroxyapatite (HAP) or conventional composites (Gradia Direct Posterior, GC; Filtek Z250 and Filtek Z500, 3M ESPE). Capping 'enamel' layers were prepared using composites (Gradia Direct Posterior, Filtek Z250 or Z550) of Al or A3 shade and the following thickness: 0.6, 1 or 2 mm. Color (Delta E) and translucency parameter (TP) were determined using a spectrophotometer (VITA Easyshade Advance 4.0, VITA Zahnfabrik). Data were statistically analyzed using analysis of variance with Tukey's post-hoc tests (alpha = 0.05). Results. TP was greatly affected by layer thickness, whilst Delta E depended on shade and layer thickness of the capping composite. HAP and Biodentine showed significantly lower TP and higher Delta E (deviation from 'ideal white') than composites (p  lt  0.05). Greater TP was seen in EverX_composite groups than in corresponding control groups of the same shade and thickness. TP of composites combined with Biodentine or HAP was below 2, lower than the corresponding control groups (p  lt  0.05). Within-group differences of Delta E were greatest in HAP_composite groups. EverX_Gradia and EverX_FiltekZ250 combinations showed the most comparable Delta E with the control groups. Significance. A 2 mm thick layer of composite covering dentin restoratives with unfavorable esthetics is recommended for a final 'sandwich' restoration that is esthetically comparable to a conventional, mono-composite control restoration.

AB  - Introduction. The aim of this study was to determine sensitivity of composite materials to ambient light by a modified standard ISO 4049:2000 and clinical working time. Materials and Methods. The following materials were tested: nano-hybrid Herculite XRV Ultra (Kerr), micro-hybrid Herculite XRV (Kerr), Zmack (Zhermack), SuperCor (SpofaDental) and Valux Plus (3M ESPE). Five samples in each group were exposed to ambient light of 8000 lx, which comprised dental unit light and natural light. After 60 sec of exposure, each sample was visually examined for signs of inhomogeneity meaning that material did not pass the test. Clinical working time was studied by applying a custom-built, standardized indenter into composite specimens of about 2 mm thickness during the same exposure to ambient light. Completion of polymerization was tested by dissolving samples in ethanol and measuring the difference in thickness before and after the test. Results were statistically analyzed using ANOVA at the significance level of 0.05. Results. Only Herculite XRV Ultra passed the test of sensitivity to ambient light, while other materials showed signs of inhomogeneity. Herculite XRV Ultra showed significantly longer working time than other composites, the average was 250 sec (p lt 0.05). The mean values of working time for other materials ranged between 117-131 sec and there was no significant difference between them (p>0.05). Conclusion. Due to the lower sensitivity to ambient light and significantly longer clinical working time compared to micro-hybrid composites, Herculite XRV Ultra can be recommended for clinical procedures that require prolonged working time with material in plastic condition.
AB  - Uvod. Cilj rada je bio da se utvrdi osetljivost kompozita na ambijentalnu svetlost prema modifikovanom standardu ISO 4049:2000 i kliničko radno vreme kompozita. Materijal i metode rada. U radu su ispitivani sledeći materijali: nanohibridni Herculite XRV Ultra (Kerr) i mikrohibridni Herculite XRV (Kerr), Zmack (Zhermack), SuperCor (SpofaDental) i ValuxPlus (3MESPE ). Po pet uzoraka u svakoj grupi je izlagano ambijentalnoj svetlosti od 8000 lx, koja se sastojala od svetlosti dentalnog reflektora i prirodne svetlosti. Nakon 60 sekundi ekspozicije svaki uzorak je vizuelno ispitivan u pogledu znakova nehomogenosti, pa ukoliko ih je bilo, smatralo se da materijal nije prošao test. Kliničko radno vreme je ispitivano utiskivanjem standardizovanog utiskivača u uzorak kompozita debljine oko 2 mm tokom izlaganja istoj ambijentalnoj svetlosti. Kontrola završene polimerizacije izvršena je rastvaranjem uzoraka u etanolu i merenjem debljine uzoraka pre i posle testa. Rezultati su statistički obrađeni primenom jednofaktorske analize varijanse (ANOVA) na nivou značajnosti od 0,05. Rezultati. Samo je Herculite XRV Ultra prošao test osetljivosti na ambijentalnu svetlost, dok su kod ostalih kompozita uočeni znaci nehomogenosti materijala. Herculite XRV Ultra je pokazao i statistički značajno duže radno vreme od drugih kompozita, prosečno 250 sekundi (p lt 0,05). Srednje vrednosti radnog vremena drugih materijala bile su 117-131 sekunda, a između njih nisu postojale značajne razlike (p>0,05). Zaključak. Zbog manje osetljivosti na ambijentalnu svetlost i značajno dužeg kliničkog radnog vremena u poređenju sa mikrohibridnim kompozitima, Herculi te XRV Ultra se može preporučiti za kliničke procedure koje zahtevaju produženo vreme rada s plastičnim materijalom.
