Teeth Hypomineralisation Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. This developmental condition is caused by the lack

  Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly.Bones that commonly break include the vertebrae in the spine, the bones of the forearm,

Typhoid fever is a life-threatening infection caused by the bacterium Salmonella Typhi. It is usually spread through contaminated food or water.

Salmonella typhi is a Gram-negative, obligate anaerobe that belongs to the serogroup D within subspecies I of the genus Salmonella, and

  Salivary duct carcinoma is a rare, typically highgrade malignant epithelial neoplasm composed of structures that resemble expanded salivary gland ducts. A low-grade variant exists. Incidence rates vary depending upon the study cited. In the AFIP files, salivary duct carcinomas represent only 0.2 per cent of all epithelial salivary gland neoplasms. More than 85 per

Oncocytic carcinoma is a rare, predominantly oncocytic neoplasm whose malignant nature is reflected both by its abnormal morphologic features and infiltrative growth. Bauer and Bauer reported the first case in 1953. Although focal oncocytic features are seen in a wide variety of salivary neoplasms, both benign and malignant oncocytic neoplasms are extremely rare. Clinical Features.

Mucinous adenocarcinoma is a rare malignant neoplasm characterized by large amount of extracellular epithelial mucin that contains cords, nests, and solitary epithelial cells. The incidence is unknown. Limited data indicate that most, if not all, occur in the major salivary glands with the submandibular gland as the predominant site. These tumors may be associated with

Cystadenocarcinoma is the malignant counterpart of cystadenoma. It is a rare malignant epithelial tumor characterized histologically by prominent cystic and, frequently, papillary growth but lacking features that characterize cystic variants of several more common salivary gland neoplasms. Clinical Features. Cystadenocarcinoma is considered to be a low-grade neoplasm. Most of the cases, about 65 per cent,
