conversation with miss Qutachi‚ I found that she has not made new friends in the city. On exam‚ I found a few cavities in her molars and generalized staining on her teeth. I asked her if she has any idea on why she developed stains on teeth. I allowed her to led the discussion on stains and she pointed out to coffee and smoking habit as potential reasons for the staining. Once she started talking about smoking‚ I asked her permission to collect some information on smoking history. I learned that she has been

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

Discussion Aloe Vera is greatly useful in the treatment of gingivitis or periodontitis (17). It decreases inflammation‚ bleeding‚ and edema of the gingiva. It is a strong antibacterial in periodontal pockets where normal cleansing is challenging‚ and its antifungal properties help considerably in the difficulty of denture stomatitis (18) .also Aloe Vera is a possible anti-bacterial factor which is mentioned to be useful in fighting the microorganism and controlling periodontal disease (19).

Background: In Jane Horack’s article “Staphylococcus epidermidis”‚ S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages.” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist Rosenback in 1884. When viewed under a microscope S. epidermidis will appear in chains‚ pairs‚ or grape-like clusters (Horak 1). Taxonomically‚ the species S. epidermidis falls in the genus Staphylococcus
