How Are They Placed?
Once the tooth has been prepared and all decay removed, chemicals and materials are placed on the tooth to increase bond strength and to protect the tooth. Next, the composite material is placed incrementally into the tooth and is hardened by exposure to a special curing light. The restoration is then contoured to fit the bite and then is highly polished. These fillings require a bit more time than the amalgam fillings because of the number of steps involved. Composite fillings can also be a bit more sensitive, at first, to extreme hot and cold and they may discolor over time if the patient smokes or drinks a lot of coffee, tea or cola. They can also be more expensive and some composites may wear faster than amalgam fillings; however, they yield a much more natural and aesthetic result. Ceramic fillings, like composites, come in several different types that can be used for different situations. Ceramics are typically used for the larger and more broken down areas. In these cases, an in
(Originally posted on About Anesthesiology) Epidural anesthesia is generally accepted as the most effective method of providing pain relief during labor. This is due to the fact that a combination of narcotics and local anesthetics are placed in the area around the spinal cord – allowing both analgesia and anesthesia. In addition, the presence of a catheter (small plastic tube going into the epidural space) allows the type and amount of medication being given to be adjusted for a variety of effects. Placement of an Epidural: When ready to place the epidural and spinal, the patient must be properly positioned. The patient can be sitting or placed on their side. Either technique is acceptable but most anesthesiologists will be more comfortable with one or the other. The patient will be instructed to arch their back out “in a C shape” or “like a cat”. This separates the vertebral bones (the bones that make up your spine) in the lower back as much as possible.
