With the change in the lifestyle of the humans, there is increase in the opportunistic infections, because increase in the immunocompromised diseases. Thus the importance of the oral fungal infections has increased during the last decades. The fungi are also components of the normal oral flora. Both yeasts and the filamentous types can cause infection of the different parts of the oral cavity s...

Tuberculosis of the oral cavity accounts for less than one percent of all cases of tuberculosis, seen in both the primary and secondary stages of the disease. It presents usually as a single, painful, ulcer however, multiple painless ulcers may also be seen. The most common location in the oral cavity is tongue. The palate, buccal mucosa, floor of the mouth, gingiva, and lip are other possible ...

Head and neck cancers comprise a heterogeneous group of mostly squamous cell carcinomas that arise in the mucosal surfaces of the upper aerodigestive tract and primarily affect the oral cavity (lips, front two-thirds of the tongue, gingivae, buccal mucosa, floor of the mouth, hard palate, and the small area behind the wisdom teeth); the salivary glands; the nasal cavity and the paranasal sinuse...

The oral cavity is the most common location in the head and neck region for primary malignant tumors. In the Western world, primary squamous cell carcinomas of the oral cavity most frequently involve the tongue and the floor of the mouth. In countries in which betel nut and tobacco chewing are common, the buccal mucosa and retromolar trigone are the most frequently encountered primary tumor sit...

Lipomas are relatively uncommon benign tumor occurring in the oral cavity with a prevalence rate of 1% to 4% of all oral lesions. They present as a slow growing, painless, asymptomatic submucosal mass and surgical excision is the treatment of choice. Oral lipomas have been known to grow to large sizes causing interference with speech, mastication and construction of denture. A case of 77 years ...

The Mucocele or Mucus retention phenomenon is a salivary gland lesion of traumatic origin, formed when the main duct of a minor salivary gland is torn with subsequent extravasation of the mucus into the fibrous connective tissue so that a cyst like cavity is produced. The wall of this cavity is formed by compressed bundles of collagen fibrils and it is filled with mucin. Mucoceles are known to ...

The possible functions of histaminergic neuron C2 were studied in an isolated head preparation from which it was possible to obtain intracellular recordings while the buccal mass exhibited feeding-like responses. Application of food to the lips of the isolated head preparation elicited rhythmic buccal movements that appeared to be ingestion responses, since they moved seaweed into the buccal ca...

MA: melanoacanthoma INTRODUCTION Oral melanoacanthoma (MA), also known as melanoacanthosis, is a benign, acquired pigmentation infrequently observed in the oral cavity. It represents a distinct entity from the cutaneous MA, which is typically seen on the trunk and is considered to be a variant of seborrheic keratosis. When it occurs in the oral cavity, MA presents as a rapidly expanding, solita...

Osseous choristoma being a benign lesion is an entity rarely seen in the oral cavity. These are usually well-circumscribed proliferations of histologically normal tissue found in abnormal locations. They are usually composed of compact bone with harvesian systems. The etiology is considered to be developmental malformation or reactive. The most common site being the tongue and other sites being...
