Purpose: The purpose of this in vitro study was to compare the effect of endocrowns and glass fiber post-retained crowns on the fracture resistance of endodontically treated premolars prepared with or without ferrule. Materials and Methods: Twenty sound mandibular premolars were endodontically treated. They were randomly assigned into 4 groups (n=5), in which, teeth were prepared to receive all...

The objectives of this study were to identify the effect of design parameters, namely marginal thickness, degree of convergence and the different interfacial conditions, on the initial failure load that induces cracking from the margin in glass-simulated dental crowns. Crown-like glass cylinders were prepared to simulate posterior all-ceramic crowns with two different marginal thicknesses (0.8 ...

Reattachment of the original tooth fragment to the fractured tooth helps in maintaining the tooth's color, wear resistance, morphology and translucency in the restoration. This article describes the reattachment of fractured fragment using a fiber post and dual cure resin cement with a self-etching adhesive. Two young male patients reported with a complicated crown fracture of the right maxilla...

Dental trauma can lead to a wide range of injuries of which crown and root fractures are examples. Crown-root fractures often need complex treatment planning. This case report describes the use of MTA in the multidisciplinary management of a patient with a horizontally fractured central incisor and luxation in a different central incisor. A 42-year-old female patient presented within 1 h of rec...

Epidemiologic aspects of traumatic dental injuries (TDI) were evaluated in the permanent dentition in a sample of 847 patients treated at the Dental Urgency Service of the Dental School of the Federal University of Goiás, Brazil, between May 2000 and May 2008. The statistical treatment analyzed data from frequency distribution and chi-square test. The level of significance was set at 5% for all...

PURPOSE The modified lateral-screw-retained implant prosthesis (LSP) is designed to combine the advantages of screw- and cement-retained implant prostheses. This retrospective study evaluated the mechanical and biological complication rates of implant-supported single crowns (ISSCs) inserted with the modified LSP in the posterior region, and determined how these complication rates are affected ...

OBJECTIVE The purpose of this study was to evaluate the effect of an educational poster on elementary school health teachers' knowledge about emergency management of traumatic dental injuries. MATERIALS AND METHODS Before poster presentation, a questionnaire was distributed to 40 health teachers (30 in the study group and 10 in the control group). One month after poster distribution, the subj...

Introduction: Among all the developmental cysts associated with crowns of a permanent tooth, dentigerous cysts is most common. Though usually present in 2 nd & 3 rd decade of life, are rarely seen during childhood. The dentigerous cyst is always associated initially with the crown of an impacted, embedded or unerupted tooth. This type of cyst is potentially capable of becoming an aggressive les...
