Domestic rabbits (Oryctolagus cuniculus) are increasingly popular as household pets; therefore, veterinarians need to be familiar with the most common diseases afflicting rabbits including dental diseases. Diagnostic approaches for dental disease include gross oral examination, endoscopic oral examination, skull radiography, and computed tomography (CT). CT overcomes many limitations of standar...

The purpose of programmed dental segmentation is to identify the person based on dental computed tomography (CT) images. Teeth play important key role in forensic dentistry. We segment the teeth image. The segmentation process consists of Otsu thresholding, morphological processing, orthogonal lines and volume of interest (VOI). In this paper, a segmented tooth is useful for the feature extract...

Aims & Objectives: To compare the fi ndings of Radiography and Computed Tomography (CT) in the diagnosis of vertical root fractures and to correlate our fi ndings post operatively. Material and Methods: We evaluated 22 cases of clinically suspected vertical root fractures those who were referred to us for Dental CT and compared fi ndings of Radiography and CT. Radiography was carried out in the...

CT-based dental imaging for implant planning and surgical guidance carries both clinical and radiographic information for implant positioning as far as trajectory, depth and distribution. The significance of accurate planning and surgical guidance as it pertains to critical anatomical landmarks, such as the mandibular canal, maxillary sinus and adjacent teeth, cannot be overstated. This case re...

Preoperative evaluation for the dental implanting normally starts with a thorough physical examination of the oral cavity and dental arches to determine the potential sites for the implant placement. Spiral dental CT plays a very important role in preoperative evaluation and postoperative follow up. It provides both 2 and 3-dimensional images, showing soft tissues and alveolar bone in each area...

INTRODUCTION Computed tomography (CT) and cone-beam CT (CBCT) are valuable diagnostic aids for many clinical applications. This study was designed to compare the gray scale value (GSV) and Hounsfield unit (HU) of selected dental materials and various hard tissues using CT or CBCT. METHODS AND MATERIALS Three samples of all test materials including amalgam (AM), composite resin (CR), glass ion...

One complication related to local anesthesia in the dental clinic is a broken needle. Although rare, a broken needle may be difficult to retrieve. Dental radiographs and 3D CT have been used in the past to confirm the location of a broken needle. We present the case of a broken needle, which was successfully removed using a careful, microscopic approach.

BACKGROUND Bleeding can be one of the severe complications during implant placement or other surgeries. Presurgical assessment of the area should be performed precisely. Thus, we examined lingual vascular canals of the mandible using dental computerized tomography (CT); define the anatomical characteristics of canals and the relationship with mandibular bone. METHODS One thousand sixty-one fo...

PURPOSE This study was performed to evaluate the changes of jaw bone density around the dental implant after placement using computed tomography scan (CT-Scan). MATERIALS AND METHODS This retrospective study consisted of 30 patients who had lost 1 posterior tooth in maxilla or mandible and installed dental implant. The patients took CT-Scan before and after implant placement. Hounsfield Unit ...
