What is the risk of pulpal necrosis in lateral luxation with a closed apex?

The correct answer is: 80%

In cases of lateral luxation with a closed apex, where the tooth is displaced laterally but the root apex is still open, the risk of pulpal necrosis is high. This is because the blood supply to the dental pulp can be severely compromised due to the traumatic displacement of the tooth, leading to necrosis of the pulp tissue. Option A (6%) is too low for the risk of pulpal necrosis in such cases. Similarly, option B (65%) is also lower than the actual risk. Option D (96%) is extremely high and an overestimation of the risk. This makes option C (80%) the most appropriate choice as it reflects the high probability of pulpal necrosis in lateral luxation with a closed apex.
