What is the risk of pulpal necrosis in intrusion with an open apex?

  1. 6%

  2. 65%

  3. 80%

  4. 96%

The correct answer is: 96%

The risk of pulpal necrosis in intrusion with an open apex is high, with a 96% chance of occurring. This is because an open apex indicates that the roots of the tooth are not fully formed, leaving the pulp chamber more vulnerable to damage. Therefore, traumatic intrusion can significantly impact the pulp tissue and increase the risk of pulpal necrosis. A, B, and C are all incorrect options as they are significantly lower than the actual risk of pulpal necrosis for this scenario. Choosing any of these options would underestimate the potential damage to the pulp and may lead to improper treatment or management. It is crucial to be aware of the high risk associated with an intrusion with an open apex to provide appropriate care for the affected tooth. Choosing option D, which reflects the actual risk, is the most accurate and important in this scenario.
