Function points were defined in 1979 in Measuring Application Development Productivity by Allan Albrecht at IBM. The functional user requirements of the software are identified and each one is categorized into one of five types: outputs, inquiries, inputs, internal files, and external interfaces.
SWELLING: Swelling is a normal occurrence after surgery and will not reach its maximum until 2-3 days after surgery. It can be minimized by using a cold pack, ice bag or a bag of frozen peas wrapped in a towel and applied firmly to the cheek adjacent to the surgical area. This should be applied twenty minutes on and twenty minutes off during the first 24 hours after surgery.
After tooth removal, it is normal to have some swelling of the surgical area and the adjacent facial tissues. Some patients may also experience bruising (black and blue) of the facial and neck skin. The maximum swelling occurs during the first 24 hours after the procedure. It then starts to slowly recede over the next 5 -7 days. To minimize the swelling, place ice packs over the affected area 10 minutes on and 10 minutes off for the rest of the day. It is not necessary to sleep with the ice pack.
