Introduction: Oral verrucous carcinoma (OVC) is a rare malignancy of the oral cavity that was first described by Ackerman. This tumor is a well-differentiated low-grade, slow growing cancer that is locally invasive without metastasis. Ameloblastoma is one of the most common odontogenic tumors, which originates from the odontogenic epithelium. Verrucous carcinoma along with central ambloblastoma...

The Mucocele are benign mucous containing cystic lesion of salivary gland mainly of traumatic origin. The wall of this cavity is formed by compressed bundles of collagen fibrils and it is filled with mucin. Mucoceles are known to occur most commonly on the lower lip, followed by the floor of mouth and buccal mucosa being the next most frequent sites. This paper presents oral mucosal lesion on l...

Photodynamic therapy (PDT) is an experimental therapy for the treatment of superficial cancer using laser light. In PDT a uniform light distribution is usually required for an optimal therapeutic effect. To irradiate part of the oral cavity uniformly for PDT, two prototype applicators were built, each for a different lower jaw. The applicators made use of the light transmitted through the wall ...

a numerical study has been done through an al2o3–water in a double lid-driven  square  cavity with various  inclination  angles  and discrete heat sources. the top and right moving walls are at low temperature. half of  the  left and bottom walls are  insulated and  the  temperatures of the other half are kept at high. a large number of simulations for a wide  range  of richardson  number  of  ...

conclusions bacterial infection has been suggested in the pathogenesis of both ss and cs. in addition, h. pylori is a resident of the oral cavity, thus may be involved in the development and progression of these lesions. hence, search for h. pylori antibody in blood of patients with ss is suggested. background sjogren’s syndrome (ss) is a chronic autoimmune disease characterized by lymphocytic ...

Introduction: This study was designed to evaluate the usefulness of mastoid cavity obliteration with combined bone pâté and Palva flap in the prevention of problematic mastoid cavities after canal wall down mastoidectomy.   Materials and Methods: In a prospective longitudinal study with a mean follow-up of 28 months conducted between 2008–2012, a series of 56 ears in 48 patients with chronic ot...

Eikenella corrodens is a facultative anaerobic bacillus which is part of the normal flora of the oral cavity and has an unusual antibiotic sensitivity for an anaerobe. The case history is presented of a young man with chest wall infiltration by Eikenella corrodens.

The larval morphology of Hypsiboas leptolineatus was studied. The tadpole has an ovoid body in lateral view, wider than deep; snout rounded with dorsal reniform nostrils; spiracle sinistral with lateral wall attached to body; anal tube dextral; tail fins convex with acuminate tip; oral disc ventral; labial tooth row formula is 2(2)/3(1); moderately developed beaks with serrated jaw sheaths. The...

We report the rare case of HES involving oral cavity associated with esophagus, and gastrointestinal tract, which we succeeded in diagnosing precisely through a biopsy specimen obtained from the lip. A 64-year-old man had dysphagia, swelling of the oral mucosa and the posterior cervical muscles, accompanied by an abdominal pain and diarrhea. Peripheral blood cell count showed marked eosinophili...
