Needlesticks and sharps injuries are a serious hazard in the dental office. Such injuries may expose he dental worker to a potentially grave, lethal risk. The centers for disease control and prevention estimates that health-care workers sustain 385,000 needlestick and other sharps related injuries in hospital-based settings annually. This amounts to 1,000 sharps injuries daily. The most common infections occupationally transmitted via sharps injuries during patient care include hepatitis B, hepatitis C,and HIV. The CDC also notes the risk includes herpes, malaria, and tuberculosis.
If you are seen for a crown/veneer and a temporary is placed, it is important that it stays in place. Teeth are constantly moving/erupting if there isn't another tooth keeping it in place. When a tooth is shaped for a crown/veneer, some of the tooth structure is removed to make room for the new crown. If the temporary comes off while waiting for the permanent crown, the newly shaped tooth can shift/move now that it's a smaller structure. It's important to re-cement the temporary in a timely manner.
When an existing crown comes off it can sometimes just be re-cemented to restore. The most common problem is that some of the tooth breaks off inside the crown and there isn't enough tooth structure to hold onto. If tooth does break off inside a crown, the tooth can be removed from inside and hopefully re-cemented. A build up can be placed on a tooth to provide strength by building it up for more tooth structure. A post and core can be placed if the tooth has had a root canal for even a stronger base. Worse case scenario the tooth would be too broken down and the tooth would have to be extracted.
A tooth which has had a root canal treatment previously may possibly become excessively tender or painful at some time following the initial root canal treatment for various reasons. Should this occur the tooth may require additional procedures, including retreatment, apical surgery, or extraction. When retreatment is necessary, the removal of the previous root canal filling material may involve difficulties such as pulp chamber or root perforation, root fracture, or other complications. This may possibly necessitate referral to a specialist or may even require extraction of the tooth. A retreated tooth may become brittle. Because of the loss of vital tissue in the pulp chamber and root canal, a tooth may become excessively brittle and break. The tooth may be preserved with a crown build up and a crown to restore the tooth unless the fracture is too severe or too extensive.
