BACKGROUND Failure of dental restorations is a major concern in dental practice. Replacement of failed restorations constitutes the majority of operative work. Clinicians should be aware of the longevity of, and likely reasons for the failure of, direct posterior restorations. In a long-term, randomized clinical trial, the authors compared the longevity of amalgam and composite. SUBJECTS, METHO...

In this paper, we propose a novel algorithm to restore calls upon a single failure in transparent optical networks. After a failure, the proposed algorithm performs a path restoration searching for the route which presents the higher optical signal-to-noise ratio. We compared our proposal to three other well known approaches in the literature. We achieved lower failure rates in the restoration ...

UNLABELLED Dental aesthetics represents a synonym for modern, cutting edge dentistry as it is a simultaneous mixture of art and science. The materials and the technology nowadays provide the resources for achieving extremely accurate and physiognomic restorations regardless of the amplitude of the intervention needed; consequently the treatment must respect the oral health and the optimal funct...

Restorative and scaling treatments have not generally provided an effective method for managing dental caries and periodontal diseases. Rather, restorative treatment has often covered up the disease processes in the short term and created a new problem: that of maintenance and re-restoration of restored teeth. Thus, standard invasive dental treatments that are commonly provided fail to address ...

Metallic materials have widespread use in dentistry for clinical treatment and restoration of teeth. Major areas of usage are: (1) restorative dentistry and prosthodontics (dental amalgam and gold alloy restorations for single teeth, metallic restorations for multiple teeth, including metal-ceramic restorations, removable partial denture frameworks, and dental implants), (2) orthodontics (wires...

background: this study was designed to compare the clinical performance of composite, strip crowns, biological restoration, and composite with stainless steel band when used for the coronal build-up of anterior teeth. materials and methods: a total of 20 patients aged 3-6 years presenting with mutilated primary anterior teeth due to caries or trauma were selected for the study using randomized ...

The objective of this study was to demonstrate the feasibility of using micro-CT scan of dental impressions for fabricating dental restorations and to compare the dimensional accuracy of dental models generated from various methods. The key idea of the proposed protocol is that dental impression of patients can be accurately digitized by micro-CT scan and that one can make digital cast model fr...

BACKGROUND Artifacts caused by dental restorations, such as dental crowns, dental fillings and orthodontic appliances, are a common problem in MRI and CT scans of the head and neck. The aim of this in-vitro study was to identify and evaluate the artifacts produced by different dental restoration materials in CT and MRI images. METHODS Test samples of 44 materials (Metal and Non-Metal) commonl...

The past decade has been turbulent for dental education, marked by debate about the future directions of the curriculum and the profession itself. The bulk of the dental school curriculum is still devoted to tooth restoration or replacement techniques, although the need for these procedures has declined. Some dental educators now advocate an oral physician model as the desired direction for the...

Mercury is among the most toxic nonradioactive elements which may cause toxicity even at low doses. Some studies showed release of mercury from dental amalgam fillings in individuals who used mobile phone. This study was conducted to assess the effect of high-field MRI on mercury release from dental amalgam filling. We studied two groups of students with identical tooth decays requiring a simil...
