BACKGROUND Knowledge about root canal morphology and its frequent variations can exert considerable influence on the success of endodontic treatment. The aim of this study was to survey the root canal morphology of mandibular first premolar teeth in a Gujarati population by decalcification and clearing technique. METHODS One hundred thirty eight extracted mandibular first premolar teeth were ...

Anomalous diffusion is studied on a certain class of percolation models in which the diffusion properties arise both from the underlying network and from the singular distribution of transfer rates. Scaling arguments parallel to those of Kogut and Straley lead to nonuniversal modifications of the dynamical exponents. The scaling results are demonstrated in a Sierpinski honeycomb and in the effe...

human mandibular premolars have earned the reputation for having an extremely complex root and root canal morphology. the incidence of multiple roots and canals in mandibular second premolars is lower than those in mandibular first premolars. mandibular second premolars with three root canals and separate foramina are very rare. in this case report, endodontic management of a three-rooted mandi...

Intraosseous migration is an unusual developmental dental anomaly, which demonstrates horizontal movement of unerupted teeth only affecting the permanent dentition of the lower jaw. Mandibular second premolar is the most common impacted tooth after the third molars and maxillary canines. Distal migration of the second premolar is rare and early loss of the permanent first molar is one of the mo...

The otherwise considered being one of the smallest and weakest teeth in the arch, mandibular second premolars have been found to almost double its size in macrodontia. Such anomalies of morphological alterations have caused the teeth to be more weak and prone to diseases, as accredited to the increased surface area and particular morphology. Bilateral mandibular second premolar macrodontia is a...

Impaction of a mandibular premolar is relatively uncommon. Ectopic placement is more unusual and there has been no discussion in the literature of an ectopic mandibular premolar in the coronoid process. In this case report, we present an impacted ectopic mandibular permanent premolar in the sigmoid notch (incisura mandibulae) region. Etiology of the tooth and treatment options are discussed and...

This case report describes an endodontic treatment of a mandibular second premolar with type IV root canal. A 26-year-old male patient reported pain in right mandibular second premolar. Clinical examination showed a large carious lesion with pulp exposure. Radiographs showed minimal periapical changes and slight widening of periodontal ligament space. Mandibular second premolars usually have on...

OBJECTIVES Anterior maxilla, known as the esthetic zone, plays an important role in facial and smile esthetics. This study assessed the frequency of implant treatments in the esthetic zone of patients presenting to Dental Implant Department of Tehran University during 2002-2012. MATERIALS AND METHODS This descriptive study was conducted on dental records of patients receiving implant treatmen...
