The emergence and development of resin-based materials, such as resin composites adhesive systems, have shifted the restorative treatment anterior teeth with caries lesions and/or fractures. Thus, based on disadvantages indirect restorations, direct esthetic restorations are options even for exten sive loss hard tissues. This study aimed to describe discuss composite restoration performed solve...

Many imaging systems produce pictures by the superimposition of two fields of frames of interlaced sequences. Pictures obtained in this way, which are termed composite frames, are severely degraded if relative motion between the camera and the scene occurs. In the presence of motion the composite frame is affected by two types of distortion: the edge staircase effect that is due to the fact tha...

This article briefly presents the classification, and possible ways of application of composites. Our objective was to compare three different restoration technique in class II cavity preparations, with the aim to determine which technique is the most advantageous in practical point of view. Artificial teeth fabricated from self-curing acrylic resin were used as models. Comparison of marginal s...

Composite resin restoration has been increasingly used in restorative dentistry with patient’s demands, and also composite resin materials as well as bonding agents have been developed continuously. Despite of these developments, several factors, such as inadequate form, wear, color mismatch, chipping or bulk fracture may still present concerns. In case of failure, the clinician must determine ...

Background Composite resin, serves as esthetic alternative to amalgam and cast restorations. Posterior teeth can be restored using direct or indirect composite restorations. The selection between direct and indirect technique is a clinically challenging decision-making process. Most important influencing factor is the amount of remaining tooth substance. Aim The aim of this systematic review ...

objectives: composite repair is a minimally invasive and conservative approach. this study aimed to evaluate the effect of an additional hydrophobic resin layer on the repair shear bond strength of a silorane-based composite repaired with silorane or methacrylate-based composite. materials and methods: sixty bar-shaped composite blocks were fabricated and stored in saline for 72 hours. the surf...

Introduction: the Restoration of endodontically treated teeth is critical, and the Awareness of stresses developed by oblique and vertical forces in restorative methods take a great role in treatment plans. Due to the anatomical shape and inherent form of the stress distribution premolars, could be lost by fractures. Some fractures such as vertical fracture which is probable in...
