Short Root Anomaly and Transverse Hemimelia: A Rare Case Presentation.

A case of Short Root Anomaly (SRA), hypodontia and taurodontism with the associated finding of transverse hemimelia, is presented. Although there is no documented evidence of a link between SRA and hemimelia, the shared genetic, environmental and metabolic factors suggest the possibility of a common underlying mechanism.

A Cone-beam Computed Tomography Evaluation of External Invasive Resorption of Unerupted Teeth. Report of Three Cases.

Tooth resorption can occur either physiologically or pathologically and can be classified as internal or external. The term "external invasive resorption" (EIR) has been used to describe lesions originating from any surface defect exposing dentin. The absence of bacterial contamination, an intact pulp space, and a lesion consisting mainly of fibrovascular tissue characterize EIR.

Transmigration of impacted canines: prevalence, management and implications on tooth structure and pulp vitality of adjacent teeth.

The aim of this study was to estimate the prevalence of transmigrant canines in a sample of panoramic radiographs of a random Greek population, to classify them and evaluate clinically and radiographically all the implications for adjacent teeth. Panoramic radiographs of 3,586 patients retrieved from eight private practices between 1998 and 2009, were examined. Panoramic radiographs with extracted canines were not included in this study.

An FTIR study of the setting reaction of various endodontic sealers.

The aim of the present study was to investigate the correlation between setting time and setting conversion in endodontic sealers. The sealers tested were Roth's 811, Endion, Sealapex, and AH-26 Silverfree. The setting time was recorded according to International Standardization Organization 6876 specification, whereas the setting conversion was monitored by micro-multiple internal reflection Fourier transform infrared spectroscopy immediately after mixing, before the setting time, at the setting time, and after the setting time.

Detection of a residual foreign body during root canal treatment.

A 25-yr old female with a 12-month history of orofacial trauma was referred to us with acute pain with positive percussion of the left mandibular first premolar and swelling in the left-posterior mandibular area. The diagnosis was pulpal necrosis with acute apical abscess. Both preoperative and length determination radiographs revealed a semi-opaque area on the root of the first premolar that was later identified as a residual fragment of windshield left in the soft tissues.
