Taurodontism is a tooth anomaly characterized by an enlarged pulp chamber and an apical displacement of the pulpal floor. It ́s more prevalent in molar teeth, with few cases reported in premolars. Objective: To describe bilateral taurodontism in lower premolars associated with supernumerary teeth in a young patient. Case report: 10-year old female patient evaluated in a routine appointment. Clin...

Background: The position of the mental foramen is critical for surgery and local anesthesia. Objectives: This study was conducted to assess the position of the mental foramen and its relationship to age in a selected Iranian population. Materials and Methods: This was a cross-sectional descriptive study. Three hundred panoramic radiographs were assessed. Three variables were assessed for each r...

Objectives: To investigate the root canal morphology of permanent mandibular premolars using cone-beam computed tomography (CBCT) in selected population and to review previous studies regarding other Turkish subpopulations. Materials Methods: The sample for this retrospective study included 1048 CBCT images 672 females 376 males representing 1613 first 1461 second premolars. Pubmed Google Schol...

Mandibular premolars have earned the reputation for having aberrant anatomy. The occurrence of three canals with three separate (type V, Vertucci) foramina in mandibular premolars is very rare. If one is to treat mandibular premolar teeth with three canals predictably, it is necessary to be aware of their clinical and radiographic anatomy. These teeth may also require special shaping and obtura...

BACKGROUND The anatomic shape of maxillary premolars show a tendency towards separation of their cusps during mastication after endodontic treatment. Preservation of the marginal ridge of endodontically treated and restored premolars can act as a strengthening factor and improve the fracture resistance. OBJECTIVES To evaluate the effect of varying thickness of marginal ridge on the fracture r...

Computer image monitoring was used for evaluation of dental arch changes. A new special device captured geometrically calibrated images permitting comparison of several different dental casts. In the first part of this study 792 sets of study casts were screened. Measurements of dental arch width between reference points of canines, first premolars and first molars were made: upper jaw: men: ca...

Isolated bilateral macrodontia of mandibular second premolars is an extremely rare dental anomaly with only 5 cases reported to date. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 12-year-old child. The patient was referred to the clinic with local crowding of mandibular posterior teeth. Radiographic findings revealed the presence of impacte...

statement of the problem using cbct to determine root morphology minimizes rate of treatment failure and adverse effects, such as gouging and perforations. purpose the aim of this study was to assess morphology of root canals using cbct scans. materials and methods in this cross-sectional study, conducted in the radiology department of hamadan dental school in 2011‒2012, 66 cbct scans were stud...
