Wood dust is recognised as a human carcinogen, based on the strong association of wood dust exposure and the elevated risk of malignant tumours of the nasal cavity and paranasal sinuses [sino-nasal cancer (SNC)]. The study aimed to assess genetic damage in workers exposed to wood dust using biomarkers in both buccal and nasal cells that reflect genome instability events, cellular proliferation ...

Retinoids have been reported to produce regressions in metaplastic changes of the mucosal epithelium. In order to define the role of these micronutrients in the prevention of squamous metaplasia of the oral cavity, it is necessary to measure their uptake in target tissues such as the buccal mucosal epithelium. We demonstrated in a trial that retinyl palmitate applied topically via a toothpaste ...

The buccal mucosa is one of the administration sites that might provide an alternative for peroral administration. Mucoadhesive buccal drug delivery systems is one of the most important novel drug delivery systems with its various advantages and it has a lot of potential in formulating dosage forms for various chronic diseases. The delivery of drugs through the buccal mucosa has attracted much ...

We examined the relationship between commonly measured features of cranial muscle activity and the magnitude of sub- and superambient pressure measured inside the buccal cavity of the striped burrfish Chilomycterus schoepfi during inflation behavior. Buccal pressure was recorded simultaneously with electromyographic (EMG) records of activity from three expansive-phase muscles (levator operculi,...

lipoma is a benign mesenchymal tumor of fat with uncertain pathogenesis. although the most common mesenchymal neoplasm in trunk and proximal portions of the extremities, it is rarely seen in the oral cavity. oral lipomas are clinically soft, smooth-surfaced nodular masses that mostly are less than 3 cm in size. typically the tumor is asymptomatic unless bitten or become noticeable because of th...

Introduction: Colon adenocarcinoma is one of the foremost causes of cancer mortality. Oral metastasis of colon adenocarcinoma is, however, rare and indicates an end-stage disease process.   Case Report: We report a case of a 69-year-old female with a gingival mass diagnosed with colon adenocarcinoma and liver metastasis after one year. A swelli...

A micro-thermistor probe was inserted into the buccal cavity of freely swimming paddlefish to measure flow velocity during ram ventilation, ram suspension feeding and prey processing. Swimming speed was measured from videotapes recorded simultaneously with the buccal flow velocity measurements. Both swimming velocity and buccal flow velocity were significantly higher during suspension feeding t...

Lipomas are the most common benign soft tissue tumors. They are usually surrounded by a thin fibrous capsule and composed of mature fat cells. Approximately 15 to 20% of cases occur in the head and neck region and only 1 to 4% occur in the oral cavity . The most common anatomic site in the oral cavity has frequently been reported as the buccal mucosa, followed by floor of the mouth, tongue and ...

Lipomas are common benign soft tissue neoplasms of mature adipose tissue. Most of lipomas develop in the subcutaneous tissues but deeper tissues may be involved as well; the oral cavity is not commonly affected. The overall incidence in the oral cavity is thought to be between 1% and 4.4% of all benign oral lesions. Oral lipomas can occur in various anatomic sites including the major salivary g...

Spindle cell carcinoma (SpCC), a variant of squamous cell carcinoma, is a biphasic malignant neoplasm that occurs mainly in the upper aerodigestive tract. It is uncommon in oral cavity, accounting for <1% of all tumors in oral cavity. Furthermore, it is uncommon for oral potentially malignant disorders such as leukoplakia to undergo transformation into SpCC. In this paper, we are reporting a ca...
