This is a case report of the presentation and the management of an apicomarginal defect which was associated with a root end fracture in an endodontically treated tooth. In spite of a successful Root Canal Treatment (RCT), if the fractured root end is left intact, considering inadverdent ankylosis or resorption, it may progress to the development of a bony dehiscence.
introduction: the aim of the present study was to evaluate the effect of three types of luting cements used for post cementation on the fracture resistance of endodontically treated maxillary premolars, restored with resin composite. materials and methods: one hundred intact single-rooted human maxillary premolars were randomly divided into 5 groups of 20 each. in groups 2-5, post spaces were p...
background and aims. the aim was to evaluate the effect of three methods of fiber insertion on fracture resistance of root-filled maxillary premolars in vitro. materials and methods. sixty extracted human maxillary premolars received endodontic treatment followed by preparation of mesioocclusodistal (mod) cavities, with gingival cavosurface margin 1.5 mm coronal to the cementoenamel junction (c...
Most of the previously reported lumbosacral nerve root avulsions presented with pseudomeningoceles at the time of delayed initial imaging. We report a case of traumatic lumbosacral nerve root injury associated with an isolated femur fracture and demonstrate the evolution of pseudomeningoceles following nerve root avulsions and edema in the perineural fat identified on the initial MR imaging.
Endodontic and Prosthetic Management of a Mid-Root and Crown Fracture of a Maxillary Central Incisor
Root fractures are relatively uncommon among other dental traumas and mostly affect the anterior dentition. This case report presents the endodontic and prosthodontic management of a maxillary central incisor with a combined fracture in the middle third of the root and the crown, as well as the 7-year follow up of the case. The healing potential of a horizontal root fracture in the middle third...

OBJECTIVE To review the literature searching for a consensus for the choice of orthodontic extrusion as treatment for crown-root fracture. MATERIALS AND METHODS An electronic search was performed in the databases PubMed, Cochrane Central Register of Controlled Trials and Scopus and a manual search of the Journal Dental Traumatology. RESULTS Forty articles were found in PubMed and 38 in Scop...
Radicular fractures in permanent teeth are uncommon injuries and account for only 0.5-7% of dental traumas. These fractures commonly result from a horizontal impact and are transverse to oblique in direction. Their incidence is more in the middle third of the root than at the apical and cervical thirds. This paper describes a case of complicated crown fracture of maxillary incisors along with h...
AIM To report a maxillary central incisor tooth with a horizontal root fracture and incomplete root development that healed and was then moved orthodontically some years after the traumatic injury. SUMMARY A 7-year-old girl attended following trauma to the maxillary anterior region. Radiologic examination revealed a horizontal root fracture in the middle third of the maxillary right central i...
