Perceiver eye movements were recorded during audiovisual presentations of extended monologues. Monologues were presented at different image sizes and with different levels of acoustic masking noise. Two clear targets of gaze fixation were identified, the eyes and the mouth. Regardless of image size, perceivers of both Japanese and English gazed more at the mouth as masking noise levels increase...

Objectives Adequate knowledge about canal anatomy is necessary for clinicians to prevent any damage to the periodontium. The aim of this study was to evaluate the canal and apical complexities of the mandibular first and second premolars in an Iranian population. Methods One-hundred mandibular first (n=50) and second (n=50) premolars were collected. After access cavity preparation, 2% methylen...

Bacterial endocarditis is the infection of inner lining of heart and /or heart valves. This disease is usually related to the presence of some pathogenic bacteria in mouth, digestive system or urinary tract. Most of the times, this infection happens in people with heart problems like the presence of prosthetic valves, history of previous endocarditis, some congenital heart defects and heart tra...

Neuropathy of the mental nerve is a rare condition that demands accurate differential diagnosis. A 69-year-old male experienced progressive hypoaesthesia of the right side of the corner of the mouth and chin, associated with intermittent phases of pain. Plain radiographs and computerised tomography (CT) scans revealed the mental foramen on the top of the toothless mandible and a symmetrically d...

use of rotary nickel-titanium (niti) instruments for endodontic preparation has introduced a new era in endodontic practice, but this issue has undergone dramatic modifications in order to achieve improved shaping abilities. cone-beam computed tomography (cbct) has made it possible to accurately evaluate geometrical changes following canal preparation. this study was carried out to compare cana...

BACKGROUND AND PURPOSE The infraorbital nerve arises from the maxillary branch of the trigeminal nerve and normally traverses the orbital floor in the infraorbital canal. Sometimes, however, the infraorbital canal protrudes into the maxillary sinus separate from the orbital floor. We systematically studied the prevalence of this variant. MATERIALS AND METHODS We performed a retrospective revi...

PURPOSE The purpose of this study was to evaluate changes in the mandibular canal and ramus morphology before and after a sagittal split ramus osteotomy. PATIENTS AND METHODS The subjects were 30 patients (60 sides) with mandibular prognathism who had undergone bilateral sagittal split ramus osteotomy setback surgery. The mandibular canal position and ramus morphology were measured at the 3 h...
