Although there are many theories as to what the cause of such a disease might be – genetics, stress, or other triggers – no one is quite sure why the disease occurs, or what could be a possible way to fully cure it. In this essay we will explore the

Experimental studies tend to use albino rats because of their passivity; it is interesting to note that albino rats and humans manifest similar symptoms for example, photosensitivity. Often drug testing or brain lesions are performed on animals to create animal models which are used to make generalizations to the human population. There are not many studies pertaining to the visual pathways in albino rats but since animal models are created to make inferences to

That would be the relationship between calcium phosphate and carious lesions. I am familiar with the remineralization process of enamel, and so I decided my topic would appropriately be that calcium phosphate can prevent carious lesions by helping to remineralize the enamel.

    Fibro-osseous lesions are disorders of bone characterized by similar histological features, where bone is replaced by connective tissue within which metaplastic calcification occurs (MacDonald-Janowski et al. 2004). However, the degree of calcification varies from one fibro-osseous subtype to another, in that a lesion may show predominance of woven bone to basophilic calcification or a combination of both (MacDonald-Janowski et al. 2004; MacDonald-Janowski et al. 2003). Fibro-osseous lesions include fibrous
