Trauma to the permanent dentition is common in children and adolescents. Almost two-third of these traumas involve a single anterior tooth. However, multiple dental injuries are often seen in high-velocity accident or sport related fall. These injuries can bring about serious damage to the tooth supporting structures and subsequent complications if inadequately treated. The present case highlig...

Background and Aim: Restoration of endodontically treated teeth is one of the most important and challenging topics in restorative dentistry. Longevity of such restorations is an essential factor in treatment planning. Amalgam build-up is a conservative method for restoration of endodontically treated teeth. Therefore, this study aimed to assess the longevity of this type of restoration in endo...

objective: secondary caries is a common problem in dental treatments and its occurrence is attributed to several factors. the present study aimed at assessing the prevalence of secondary caries in posterior teeth of patients presenting to the department of operative dentistry, shahid beheshti dental school.   methods: this descriptive study was conducted on 350 patients with 1,339 posterior tee...

The Ontologies in Oral Health and Diseases project aims to support dental research by allowing researchers to more easily access infor-­‐ mation contained in electronic dental record systems. The Oral Health and Disease Ontology (OHD) is at the core of the project. ...

The appearance of the upper anterior teeth in the preoperative situation was unsatisfactory. Tooth 11 looked particularly unattractive. Neither its shape nor its shade satisfied the standards of a high-quality dental restoration. In order to obtain a clearer picture of the preoperative situation, a greyscale image was produced (Figure 1). This image illustrates the insufficient brilliancy as we...

this case report refers to the esthetic and functional restorations of extensively damaged maxillary central incisors with dental caries in a 32-year-old woman, with the use of posts and crowns made from natural extracted teeth. proper restoration of such teeth with the use of natural teeth fragments are known as “biological restoration.” biological restorations can be done by using the fragmen...

Purpose: Dental amalgam has been used as a dental restoration for more than 165 years. However, some patients with these restorations may present oral lichenoid lesions (OLL). OLL are chronic oral mucosal contact reactions to dental amalgam. Their diagnosis usually is based on the direct contact of the affected mucosa with the amalgam restorations, clinical appearance, and lack of migrations. A...

Tooth extraction is a traumatic procedure initiating a complex cascade of biochemical and histologic events that inevitably lead to a reduction of alveolar bone and soft tissue. These tissue alterations often lead to an esthetic compromise of the future implant restoration. The hard- and soft-tissue architecture surrounding the extraction defect largely dictates the course of dental implant tre...
