Introduction: Mast cells are large granular cells that arise from a multipotent CD 34+ precursor in the bone marrow normally distributed throughout connective tissues. The most common method to study role of mast cells in any altered condition involves their identification and quantification in that condition and compare the values with that of the normal average count or number of mast cells. ...

INTRODUCTION Bioimpedance is a measure of the electrical properties of biological tissues. In the last two decades bioimpedance has been successfully introduced in clinical diagnosis of cancer. It has been demonstrated that tumoral tissues often show lower bioimpedance values than healthy tissues. The aim of this work is to assess the bioimpedentiometric differences between healthy and Oral Lic...

Removable complete and partial dentures are supported by the residual alveolar ridges consisting of mucosa, submucosa, periosteum, and bone. An understanding of the biomechanical behavior of the oral mucosa is essential in order to improve the denture-bearing foundations for complete and partially edentulous patients. The purpose of this paper was to examine the biomechanical behavior of the so...

oral cavity t-cell lymphoma occurs rarely. this case report describes a patient with such a tumor. the case was a 75 years old man presented with a painless swelling on his hard palate mucosa. he had suffered from nose- bleeding and nasal obstruction. pathology revealed the presence of a t-cell lymphoma tumor in the palate. though rare, the signs and symptoms of the case suggest that t-cell lym...

OBJECTIVES The purpose of this study was to evaluate the expression of cdk4 and p16, the proteins implicated in hyperproliferation and arrest in oral lichen planus and to compare their expression in erosive and non-erosive oral lichen planus and with normal mucosa and oral squamous cell carcinoma. MATERIAL AND METHODS Analysis of cdk4 and p16 expression was done in 43 erosive oral lichen plan...

The primary function of the immune system of the mouth is to protect the teeth, jaws, gingivae and oral mucosa against infection. These host defences vary in the different oral microenvironments or domains represented by the oral mucosa, saliva and gingival crevice. This review aims to consider and contrast the main immune components in each domain and cites examples of oral diseases where the ...

background: the health risks of crack cocaine smoking on the oral mucosa has not been widely researched and documented. objective: the purpose of this study was to analyze the proliferative activity of oral epithelial cells exposed to crack cocaine smoke using silver nucleolar organizer region (agnor) staining. methods: oral smears were collected from clinically normal-appearing buccal mucosa b...

In view of the morbidity potential of oral complications in patients with leukemia, this study evaluated the clinical and microbiological alterations that occur in the oral mucosa of children with acute lymphoblastic leukemia (ALL) undergoing antineoplastic chemotherapy and prophylactic administration of 0.12% chlorhexidine gluconate. The sample consisted of 17 children aged 2 to 12 years that ...

BACKGROUND To determine the prevalence and clinicopathologic features of the oral cancer patients. MATERIAL AND METHODS Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, pala...
