Central adenocarcinoma of the jaws is an extremely rare malignant tumor. We reported a case of poorly differentiated adenocarcinoma occurring intraosseously in the maxilla. A 62-year-old male was referred to our hospital because of swelling of the palate. MRI showed a central tumorous lesion in the maxilla. He underwent maxillectomy combined with neck and parapharyngeal dissection. Histologic e...

Received: 3 May 2007 Accepted: 9 October 2007 Abstract: A 28-year-old male farmer presented with a chief complaint of itching and extreme discomfort on the entire maxillary and mandibular gingivae. He was diagnosed with gingival myiasis and scaling was performed on both jaws. However because of the multiple larvae, complete removal with simple curettage and scaling was not feasible, therefore f...

The stingray family Myliobatidae contains five durophagous (hard prey specialist) genera and two planktivorous genera. A suite of morphological features makes it possible for the hard prey specialists to crush mollusks and crustaceans in their cartilaginous jaws. These include: 1) flat, pavement-like tooth plates set in an elastic dental ligament; 2) multiple layers of calcified cartilage on th...

Panoramic radiographs provide proper information for most oral surgery procedures panning, for the evaluation of orthodontic treatments progress, for growth and development of children follow up and for oral health surveys in specific populations. Furthermore, the panoramic imaging allows the complete visualization of dental and bone anatomic landmarks and structure in the maxilla and mandible ...

Advancements in robotics have led to significant improvements in robot-assisted minimally invasive surgery. The use of these robotic systems have improved surgeon dexterity, reduced surgeon fatigue, and made remote surgical procedures possible. However, commercially available robotic surgical systems do not provide any haptic feedback to the surgeon. This paper describes our design of an automa...

Periodontal diseases and wearing dentures for extended periods cause the atrophy of the alveolar ridges. Removable dentures are hard to manage for these kinds of patients. In order to construct fixed prostheses for these patients, complicated surgeries are necessary for implant placement. Hybrid prosthesis on tilted implants are simple solution for these kinds of patients. Two patients with sev...

Histiocytosis is a term applied to a group of rare disorders of the reticuloendothelial system. Eosinophilic granuloma, the most benign and localized of the three Langerhans cell histiocytosis entities, may be solitary or multiple. Eosinophilic granuloma can affect almost any bone, but commonly involves the mandible when the jaws are affected. Conventional treatment of LCH is with surgery, radi...

A myriad of extirpative surgical protocols for the management of benign tumors of the jaws have been presented in the literature. Through significant advancements in computer-aided design and computer-aided manufacturing (CAD/CAM) technology and surgical instrumentation, today surgeons have at their disposal robust technology-driven techniques that are aimed at improving surgical outcomes. Our ...

High-performance Web servers are essential to meet the growing demands of the Internet and large-scale intranets. Satisfying these demands requires a thorough understanding of key factors affecting Web server performance. This paper presents empirical analysis illustrating how dynamic and static adaptivity can enhance Web server performance. Two research contributions support this conclusion. F...
