AIM – The aim of this study was to evaluate marginal sealing ability of newly introduced Dyad Flow with total etch & self-etch adhesive system at the coronal and apical margins of class V resin composite restorations. MethodsA standard class V cavity (3 mm mesiodistal width, 3 mm occlusogingival height, and 1.5 mm axial depth) was prepared on the buccal surface of freshly extracted sound human ...

Aim: To evaluate and compare the surface roughness of nano ionomer, microhybrid composite, and resin modified glass ionomer cement. Method: A total of 30 PVC moulds of dimension (diameter 8mm height 2mm) were prepared. The total of 30 specimens was divided into three groups each consisting of 10 discs each. Group110 discs made of microhybrid composite (Z250, 3M ESPE, St. Paul, MN, USA), Group 2...

OBJECTIVE The aim of this in vitro study was to evaluate the marginal sealing ability of a bulk fill flowable resin composite on both enamel and dentin substrates. MATERIALS AND METHODS 48 non-carious molars were selected and four Class-V cavities were prepared at the CEJ of each sample. Cavities were filled with Venus Diamond (Heraeus Kulzer); Venus Diamond Flow (Heraeus Kulzer) and Surefil ...

INTRODUCTION Whitening toothpastes which have been accepted in populations may affect properties of enamel and restorative materials. The aim of this study was to compare the microhardness of human enamel and Z250 microhybrid composite resin after brushing with two whitening toothpastes. MATERIALS AND METHODS In this experimental study of enamel specimens, forty five freshly extracted human i...

OBJECTIVES The aim of this study was to evaluate the clinical performance of a nanohybrid and a microhybrid composite in class I and II restorations after 3 years. SUBJECTS AND METHODS A total of 82 class I and class II restorations were performed in 31 patients (10 males and 21 females) using Grandio and QuiXfil with self-etch adhesives (Futurabond and Xeno III). The restorations were clinic...

The aim of this study was to evaluate the degree of conversion by Knoop microhardness (KHN) and FT-Raman spectroscopy (FTIR) of one nanofilled (Filtek Supreme-3M-ESPE [FS]) and one microhybrid composite (Charisma-Heraeus-Kulzer [CH]), each with different opacities, namely enamel, dentin, and translucent, which were photo-activated by a quartz-tungsten-halogen lamp (QTH) and a light-emitting dio...

Introduction: Composite materials may be exposed to chemicals in food and beverages the oral cavity, which can lead changes surface roughness. The aim of this vitro study was evaluate roughness two restorative after exposure coffee green tea followed by a dental bleaching procedure. Methods: For nanofilled composite microhybrid composite, 15 samples each were fabricated. Five specimens from sto...
