The objective of this study was to evaluate the discolouration effects artificial saliva, granule lemon juice, coffee (without sugar), coca cola, sour cherry fresh carrot juice and red wine on resin-based composite materials that are commonly used in restorative dentistry.Colour four brands resin composites (Filtek Z 250 (3M Espe), Filtek Supreme Quadrant (Cavex), Charisma (Heraeus-Kulzer)) A2 shade measured after one day immersion eight different solutions. Colour measurements were obtained...
ABSTRACT Objectives: The aim of this study was to evaluate the effects 3 commercially available mouth rinses on color stability 4 different resin-based composite restorative materials. Methods: Forty disc-shaped specimens (10x2 mm) were prepared from each following materials: A nanofill Filtek Supreme XT (3M/Espe, St. Paul, MN, USA); a packable lowshrinkage composite, AeliteLS Packable (BISCO, Inc, Shaumburg, IL, nanoceramic compositeresin Ceram-X (Dentsply, Konstanz, Germany); microhybrid...
Dental education consists of both theoretical and practical learning for students to develop competence in treating patients clinically. When dental encounter courses their first year as a new educational experience, they must also learn evaluate themselves. Self-evaluation is an essential skill professionals keep increasing over the course careers. The aim this study was compare assessment scores second- third-year faculty two consecutive preclinical exams restorative dentistry school...
Clinical Relevance Nanohybrid and low-shrinkage posterior resin composites, placed with self-etch adhesive systems in teeth, showed satisfactory similar results after two years.
This study evaluated the color parameters of resin composite shade guides determined using a colorimeter and digital imaging method.Four guides, namely: two nanohybrid (Grandio [Voco GmbH, Cuxhaven, Germany]; Premise [KerrHawe SA, Bioggio, Switzerland]) hybrid (Charisma [Heraeus Kulzer, GmbH & Co. KG, Hanau, Filtek Z250 [3M ESPE, Seefeld, Germany]) were evaluated. Ten tabs selected (A1, A2, A3, A3,5, A4, B1, B2, B3, C2, C3) from each guide. CIE Lab values obtained (ShadeEye NCC Dental Chroma...
ABSTRACT Objectives: The purpose of this study was to evaluate and compare the 12 month clinical performances two different posterior composites in Class I II restorations. Methods: Thirty-one patients (10 male, 21 female) were recruited into study. A total 82 cavities restored with either a nanohybrid composite (Grandio) or low-shrinkage (Quixfil), using their self etch adhesives (Futura Bond Xeno III) according manufacturers instructions. restorations clinically evaluated 1 week after...
Purpose: The aim of this in vitro study is to instrumentally compare the color stability two different one-shade and a multi-shade universal composite resin material after light-cure soft start (SS) standard (ST) curing modes. Materials Methods: Seventy-eight discs were prepared using materials (Omnichroma Vittra Unique) A2 shade resin-based (Filtek Z250, 3M) when half them was light-cured ST SS mode (n=13). samples placed 5 ml coffee solution incubated at 37 °C for 30 days staining...
The effect of different staining solutions and a bleaching procedure on color stability surface roughness nanohybrid resin composite were evaluated with or without liquid polishing (RP).Ninety-six disc-shaped specimens (A1 Shade, Z550 Filtek 3M ESPE, St. Paul, MN, USA) prepared divided randomly into two groups (n = 48). Liquid RP (BisCover LV, Bisco Inc., Schaumburg, IL, was applied in one group (RP) not the other (P). Specimen determined using colorimeter profilometer, respectively. After...
The aim of this study was to evaluate the clinical performance a nanohybrid and microhybrid composite in class I II restorations after 3 years.A total 82 were performed 31 patients (10 males 21 females) using Grandio QuiXfil with self-etch adhesives (Futurabond Xeno III). clinically evaluated by 2 operators 1 week placement (baseline) at 6 months 1, 2, years modified United States Public Health Service (USPHS) criteria. At 3-year follow-up, 62 cavities reevaluated 23 (7 16 females)....
The aim of this study was to evaluate the effects sodium ascorbate on bond strength different adhesive systems NaOCl-treated dentin. Eighty extracted molar teeth were used in study. buccal enamel surfaces removed obtain a flat dentin surface. mounted self-curing resin and irrigated with NaOCl for 10 min. Half specimens treated randomly assigned four subgroups according (Clearfil SE Bond, Clearfil Tri-S Adper Prompt-L-Pop, Single Bond 2). strengths determined Universal Testing Machine, at...
To evaluate the clinical performance of two different microhybrid resin composites in noncarious cervical lesions (NCCLs) after 24 months.Ninety-seven NCCLs were restored with either TPH Spectrum (n = 48) or Filtek Z250 49) using an etch-and-rinse adhesive 20 patients. The restorations clinically evaluated modified United States Public Health Service criteria for retention, color match, marginal discoloration, adaptation, surface texture, anatomic form, postoperative sensitivity, and...
Amaç: Bu in vitro çalışmanın amacı üç farklı diş rengindeki restoratif materyalin (bir mikrohibrit kompozit rezin [Charisma [Heraeus-Kulzer] , bir nanohibrit [Ice [SDI] ve geliştirilmiş modifiye cam iyonomer siman [ACTIVA Restoratif [Pulpdent]) beş renklendirici solüsyon (çay, kahve, kola, kırmızı şarap distile su) içinde bekletilmesi sonrası renk stabilitelerinin değerlendirilmesidir. Gereç Yöntem:Her materyalden plastik kalıp kullanılarak 5 mm çapında 2 kalınlığında 45 silindir şekilli...
Dental surface conditioning by Er:YAG laser is currently being investigated, as not all of the mechanisms and effects this technique have been clearly studied. Thus, aim present study was to assess cervical microleakage Class II resin composite restorations in endodontically treated teeth following either respective conventional or additional conditioning, association with varied adhesives.Standardized mesial-occlusal-distal cavities (two gingival walls positioned dentin enamel,...
Amaç: Bu çalışmanın amacı, farklı profesyonel dental profilaksi işlemlerinin bir mikrohibrit (Charisma, Heraeus-Kulzer) ve nanohibrit (Ice, SDI Dental) kompozit rezinin yüzey pürüzlülüğü üzerine etkisini değerlendirmektir.Gereç Yöntem: Her restoratif materyalden 45 adet disk şekilli örnek (2 mm kalınlık 8 çapında, toplam 90 örnek) plastik kalıplar kullanılarak hazırlandı.
