Length and geometric patterns of the greater palatine canal observed in cone beam computed tomography.

The greater palatine canal is an important anatomical structure that is often utilized as a pathway for infiltration of local anesthesia to affect sensation and hemostasis. Increased awareness of the length and anatomic variation in the anatomy of this structure is important when performing surgical procedures in this area (e.g.

The prevalence of concha bullosa and nasal septal deviation and their relationship to maxillary sinusitis by volumetric tomography.

The objective of this study was to determine the prevalence of concha bullosa and nasal septal deviation and their potential relationships to maxillary sinusitis. 883 CT scans taken at Creighton University School of Dentistry from 2005 to 2008 were retrospectively reviewed for the presence of concha bullosa, nasal septal deviation, and maxillary sinusitis. 67.

Transitory paresis of the lateral pterygoid muscle during a posterior superior alveolar nerve block--a case report.

The posterior superior alveolar nerve (PSAN) is a major sensory branch of the maxillary division of the trigeminal nerve. A PSAN block is a dental nerve block used for profound anesthesia of the maxillary molars. Complications arising from the PSAN block include hematoma formation, transient diplopia, blurred vision, and temporary blindness.

Comparison of clinician agreement during visualization of conventional and digitized bitewing radiographs.

Digital technology is becoming more common in dental practices. Indirect digitization of radiographs can be an alternative to direct digital systems. This study was designed to evaluate intra-observer, inter-observer, and inter-technique agreement of proximal caries diagnosis on bitewing radiographs before and after indirect digitization.

Aberrant root formation: review of root genesis and three case reports.

The mechanism of root formation and tooth eruption is a complex process which is not fully understood. Prior to a tooth emerging into the oral cavity, root genesis is initiated by derivatives of the enamel organ. The dental follicle mediates an eruption pathway allowing for movement of the developing tooth in a coronal direction.
