Evidence is accumulating that dendritic cells (DCs) from the intestines have the capacity to induce Foxp3(+)CD4(+) regulatory T cells (T-regs) and regulate immunity versus tolerance in the intestines. However, the contribution of DCs to controlling immunity versus tolerance in the oral cavity has not been addressed. Here, we report that DCs from the oral cavity induce Foxp3(+) T-regs as well as...

PURPOSE This study aimed to identify factors associated with the occurrence of primary cancer of the lip and oral cavity regions compared to other types of head and neck cancers according to demographic, socioeconomic data and lifestyle, in Brazil, from 2000 to 2011. METHODS A study was conducted using Hospital Cancer Records (Instituto Nacional do Câncer), from 2000 to 2011, totaling 23,153 ...

Staphylocoocci are minor members of normal oral flora, but they are always detected in the oral cavity. The biological activities of oral staphylococci , however, have not been noticed as much . We reported earlier on the production and the characterization of a bacteriocin of S. aureus isolated from saliva1) , which may contribute to the establishement of the oral ecosystem. Recently , we obse...

cancer of the oral cavity accounts for approximately 3% of all malignancies diagnosed annually in 270,000 patients worldwide. oral cancer is the 12th most common cancer in women and the 6th in men. many oral squamous cell carcinomas develop from potentially malignant disorders (pmds). lack of awareness about the signs and symptoms of oral pmds in the general population and even healthcare provi...

A case of neurilemmoma at the ventral surface of the tongue was reported with a review of the literature.

BACKGROUND Except for early T1,2 N0 stages, the prognosis for patients with oral cavity cancer (OCC) is reported to be worse than for carcinoma in other sites of the head and neck (HNC). The aim of this work was to assess disease outcome in OCC following IMRT.Between January 2002 and January 2007, 346 HNC patients have been treated with curative intensity modulated radiation therapy (IMRT) at t...

Hemangiomas are tumors of blood vessels identified by rapid endothelial cell proliferation in early infancy followed by involution over time. All other abnormalities are malformations resulting from anomalous development of vascular plexuses. This lesion in the oral cavity is not common. Despite its benign origin and behaviour, it is always of clinical importance to the dental profession and re...

Reconstruction of oral cavity defects must maximize residual function of remaining tissue. The reconstructive surgeon should have the ability to tailor the reconstruction according to the size of the defect and general medical status of the patient. The reconstructive ladder is a useful paradigm to conceptualize different types of reconstruction. Free tissue transfer has allowed reconstruction ...

UNLABELLED Lymphangiomas are uncommon congenital hamartomas of the lymphatic system, usually diagnosed in infancy and early childhood. Commonly located at head and neck, they are rarely situated in the oral cavity. Preferred site of oral involvement is the tongue. In the absence of proper therapy, lymphangiomas of the tongue are extremely recurrent, leading to serious complications such as hemo...
