AIM To evaluate the cost-effectiveness of root canal treatment for a maxillary incisor tooth with a pulp infection, in comparison with extraction and replacement with a bridge, denture or implant supported restoration. METHODOLOGY A Markov model was built to simulate the lifetime path of restorations placed on the maxillary incisor following the initial treatment decision. It was assumed that...

BACKGROUND Clinical studies are being conducted in less strict conditions in order to establish an adequate scientific basis for decision making. The aim of this pragmatic randomized clinical trial is to evaluate the effectiveness of single and multiple-surfaces restorations performed following the Atraumatic Restorative Treatment (ART) premises compared with Conventional Treatment (CT) using b...

We consider protection and restoration mechanisms for hierarchical optical networks with different granularities of paths (wavelengths and wavebands). We formulate an Integer Linear Programming description for the problem and propose a shared-path waveband protection algorithm. We further demonstrate its efficiency by analyzing its equipment cost and capacity utilization.

This case report demonstrates the benefit of using the shortened dental arch (SDA) design for a comprehensive implant-supported restoration and the avoidance of the complexities of implant placement near the maxillary sinus. The SDA concept as a treatment option is encouraging in terms of function, patient satisfaction, and cost-effectiveness.

With new requirements being placed on the distribution grid, the cost to consumers of poor supply quality and low reliability is increasing. Consumers are starting to demand higher levels of supply quality from distribution network operators. This paper will discuss various Fault Location, Isolation and Service Restoration (FLISR) strategies with increasing CAPEX investment potential that can b...

INTRODUCTION Despite the widespread acceptance of conventional treatment using composite resin in primary teeth, there is limited evidence that this approach is the best option in paediatric clinics. Atraumatic restorative treatment (ART) using high-viscosity glass ionomer cement has gradually become more popular because it performs well in clinical studies, is easy to handle and is patient fri...

Introduction: The restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. The aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. Methods: E...

We consider signal and image restoration using convex cost-functions composed of a non-smooth data-fidelity term and a smooth regularization term. First, we provide a convergent method to minimize such cost-functions. Then we propose an efficient method to remove impulsive noise by minimizing cost-functions composed of an l1 data-fidelity term and an edge-preserving regularization term. Their m...

introduction: this in vitro study evaluated the influence of composite thickness (with or without fiber reinforcement) on fracture resistance of direct restorations in endodontically treated teeth. methods and materials: fifty-six intact human premolars were chosen and randomly divided into four groups ( n =14). after preparation of a mesio-occluso-distal (mod) cavities and cusp reduction, the ...

We extend Real Option Theory to evaluate natural resource development projects that may bring negative net bene ts and require costly restoration. Based on a new concept, irreversibility cost, we show that the degree of irreversibility becomes an endogenous choice, rather than an exogenously given economic constraint. The xed cost of restoration has continuous impacts, over and above the widely...
