OBJECTIVE Accurately localizing the mental foramen and mandibular canal is important when administering local anesthesia and performing surgery; therefore, knowing the normal range of the possible locations is essential. Our purpose was to assess the location of the mental foramen and mandibular canal in an Iranian population using panoramic radiography. MATERIALS AND METHODS Standard panoram...

We compared the feature tuning of neuronal activity in area 21a with the tuning in areas 17/18. Local field potentials and multi-unit activity recorded in alert animals showed similar selectivity to orientation in both areas, higher selectivity to spatial frequencies in areas 17/18 and higher selectivity and tuning significance to temporal frequencies in areas 17/18. In addition, only at sites ...

BACKGROUND AND OBJECTIVES The aim of this study was to compare internal anatomy between first and second mandibular premolars and to study different percentage variations of root canal morphology of mandibular premolars in Gujarat population based on Vertucci's classification by clearing technique. METHODOLOGY A total of 80 extracted intact permanent mandibular premolars (40 each mandibular f...

The objective of this study was to evaluate the location of the mandibular canal and the thickness of the occlusal cortical bone at dental implant sites in the lower second premolar and lower first molar by using dental cone-beam computed tomography (CBCT). Seventy-nine sites (47 second premolar and 32 first molar sites) were identified in the dental CBCT examinations of 47 patients. In this st...

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...

PURPOSE The objective of this study was radiographic assessment of the premolar teeth abutments alveolar bone resorption in mandibular Kennedy Class I removable partial denture (RPD) utilizing the broad stress distribution philosophy, either designed with multiple circlet clasp or compound Aker clasp. MATERIALS AND METHODS Twelve patients were enrolled for this study with upper completely ede...

OBJECTIVE The primary aim of the study was to generate new prediction equations for the estimation of maxillary and mandibular canine and premolar widths based on mandibular incisors and first permanent molar widths. METHODS A total of 2,340 calculations (768 based on the sum of mandibular incisor and first permanent molar widths, and 1,572 based on the maxillary and mandibular canine and pre...
