A patient, Mr. X presented with intense pain. He was unable to bite to chew on his upper right teeth.
His Medical History was normal and he had no history of tooth injury.
On clinical examination, the upper right first premolar was very sensitive to electrical pulp test, cold and tender to percussion. He felt a sharp pain when biting on a cotton roll. There was no pain at night and pain was only elicited when biting.
It became evident when the oral camera revealed a channel running across the biting surface of the tooth.
X-ray taken shows general bone loss and especially on the mesial of the upper right first premolar. No signs of root fractures. The tooth next to the painful one has some caries.
Crack tooth syndrome involving the upper right first premolar.
The upper second molar appears to have some pathology at the root tip and require further investigation.
Possible Causes: 1 Lack of posterior or back molars
2 Patient’s habit of biting very hard stuff
3 Night grinding
