A rare morphological variant of the first maxillary premolar: a case report.

Anatomical variations of the dental root morphology may lead to endodontic treatment failure. Knowledge of root morphology and possible anatomical variations may ensure proper endodontic treatment and long-term success. The present study describes the case of a three-rooted maxillary right first premolar with two buccal roots and one palatal root, each of them having one canal, diagnosed with symptomatic irreversible pulpitis.

Anatomical and clinical considerations regarding the greater palatine foramen.

Objective: In this study, we mapped the topography of the greater palatine foramen (GPF), within the South-Eastern European population, according to clinically identifiable anatomical landmarks.

Materials And Methods: We used 100 dry adult human skulls, of which 75 were bilaterally dentate, whereas 25 were partially edentulous.

Results: The shape of the GPF was oval in 84% of the cases.

A radiographic study regarding post retained restorations.

Unlabelled: The aim of this study was to evaluate the incidence of intraradicular retention and the prevalence of different types of posts used for the restoration of endodontically treated teeth, in clinical practice.

Materials And Methods: The study was performed on 94 digital panoramic radiographies that allowed a comprehensive appreciation. Root canal fillings and the posts were identified on these radiographies and their correctness and quality were assessed by measurements according to the data provided by the specialized literature references.
