The prothrombin levels that is of concern to dentist extraction is
1) 20 % normal PT
2) 40 % normal PT
3) 50 % normal PT
4) 100 % normal PT
Oral Pathology
Answer: 1
Prothrombin time (PT) is a measure of the blood's clotting ability. In dentistry, a PT level of 20% below normal is often considered a threshold for increased risk of bleeding during surgical procedures such as tooth extraction. At this level, the patient may be at risk for prolonged bleeding or hemorrhage. Dentists typically assess a patient's coagulation status before performing invasive procedures, especially if the patient has a known bleeding disorder or is on medications that affect clotting.
