Scatter charts and line charts look very similar, especially when a scatter chart is displayed with connecting lines. However, there is a big difference in the way each of these chart types plots data along the horizontal axis (which is also known as the x-axis) and the vertical axis (which is also known as the y-axis).
From Wikipedia, the free encyclopedia. A buccal exostosis (also termed alveolar exostosis), is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible. Some consider them a variation of normal anatomy rather than a disease.rom Wikipedia, the free encyclopedia.

A mouth ulcer is the loss or erosion of part of the delicate tissue that lines the inside of the mouth (mucous membrane). Some of the causes include certain medications, chemicals and infectious diseases such as herpes or thrush. The most common cause is mechanical injury, such as accidentally biting your cheek. In most cases, mouth ulcers are harmless and resolve by themselves in a few days without the need for medical treatment.
