Saliva is an important agent against cavities, as it flushes away some sugars and buffers the acidity in the mouth. It contains antibacterial compounds and enzymes (Amylase) which start the digestion process. These enzymes break down food in between teeth. Saliva has butters that keep the mouth’s pH level slightly alkaline (having a pH greater than 7). Without the pH being slightly alkaline, the early stage of digestion that occurs in the mouth would harbor many tooth-eating bacteria. Nevertheless, the consistency of saliva impacts its effectiveness. Thinner saliva breaks away food and washes it away quickly while thick saliva produces more acid-producing ba...

...hy. Many of these healthy diets include healthy portions of fruit. This project determined how different fruits would effect oral bacterial growth and therefore would be of use to these dieters, who may be questioning “Which fruit is better for me?” In terms of keeping their mouth healthy as well as their body, this project would help them choose a fruit to eat in the in the middle of the day or before brushing. Pears, the fruit that caused the least bacterial growth, are also healthy for the body in that they help lower cholesterol and are an excellent source of dietary fibers and vitamin C. This project would also help the American parents and children in terms of packing a lunch. Most children do not brush their teeth after lunch in school, and so parents could pack a pear or banana for lunch instead of an apple or orange to prevent cavities or dental erosion.

- The oral cavity is home to a great variety of primitive organisms. It is the gateway to two of the most imperative body systems, the gastrointestinal and the respiratory systems. The oral cavity is the drainage to secretory glands called the salivary glands of which there is between 600-1000 small glands located throughout the mouth. They are exocrine glands that release their secretions through tiny ducts that open into the mouth. There are three major pairs of salivary glands however that contribute the most to the oral secretion and these are; the parotid gland, which is the largest and it is located at the back of the jaw, the submandibular gland, located in the lower jaw, and the sublin...

- Mouth and Teeth The functions of the mouth, with the help of the teeth, work together to digest food. Teeth mechanically breakup food, in order for enzymes and acids to work it’s way through it. The mouth hosts the mechanical breakdown of foods. The salivary glands in the mouth, release an enzyme, called Amylase, which is used to breakdown carbohydrates. The teeth are usually 32 small hard organs, which are designed with the hardest material in your body, enamel, that grind and cut food into small pieces for swallowing....

- Besides being able to seize an entire continent in the panicked grips of an epidemic, viruses also have the potential to do good. Such is the purpose of virotherapy – using viruses to selectively target and kill cancer cells, effectively stopping tumour growth in one fell swoop. In the war on cancer, the 200 types of cancer collectively claim almost half a million deaths yearly. The traditional tag team of radiation therapy and chemotherapy undoubtedly have their limits, and now more than ever are new developments needed.... [tags: virotherapy, metastatic, apoptosis]
