Most salivary gland tumors arise from the epithelium of the duct apparatus, but occasionally lesions seem to show acinar cell differentiation. Acinic cell carcinoma is a malignant epithelial neoplasm in which the neoplastic cells express acinar differentiation.

The ranula is a form of mucocele that specifically occurs in the floor of the mouth. The name is derived from the Latin word rana, which means frog, because the swelling may resemble a frog’s translucent underbelly.

The mucocele is a common lesion of the oral mucosa involving salivary glands and their ducts. They result from traumatic severance of a salivary duct, such as that produced by biting the lips or check, pinching the lip by extraction forceps, and the like, leading to spillage of mucin into the surrounding tissues.

Recording the Orientation Jaw Relation using A Kinematic Face-bow in a Dentulous Patient : The mechanism of operation of the apparatus is similar to arbitrary face-bow. Of course there are a few differences, which are as follows: • An accurate impression of the mandible and maxilla should be made. • Stone casts are fabricated
The objectives of furcation therapy are to (1) facilitate maintenance, (2) prevent further attachment loss, and (3) obliterate the furcation defects as a periodontal maintenance problem. The selection of therapeutic mode varies with the class of furcation involvement, the extent and configuration of bone loss, and other anatomic factors. Therapeutic Classes of Furcation Defects Class

Squamous Papilloma The oral squamous papillomas are seemed to be associated with papilloma viruses, the one commonly incriminated as causative in skin warts. It is the fourth most common oral mucosal mass and is found in four of every 1,000 and accounts for 3-4 percent of all biopsied oral soft tissue lesions. The HPV types

FOCAL INFECTION Focus of infection refers to a circumscribed area of tissue, which is infected with exogenous pathogenic microorganisms and is usually located near a mucous or cutaneous surface. This should be carefully distinguished from focal infection. The theory of focal infection played a domi- nating role in medicine for many years and has been
MAXILLARY SINUSITIS Maxillary sinusitis, an acute or chronic inflammation of the maxillary sinus, is often due to direct extension of dental infection, but originates also from infectious diseases due to bacteria, fungus, or virus such as the common cold, influenza and the exanthematous diseases; from local spread of infection in the adjoining frontal or paranasal

Dens in Dente It is also called as ‘dens invaginatus’ or ‘dilated composite odontome’ or ‘gestant odontome’. Infolding of the outer surface of the tooth into its interior surface occurs. It is a developmental variation which is thought to arise as a result of an invagination in the surface of crown before calcification. Etiology Focal
