Re: Cracked Teeth: Diagnosis

[Anonymous]

SIGNS AND SYMPTOMS
Patient complains of pain ranging from mild to excruciating,at the initiation or release of the biting pressure
It mimics the condition as severe as trigeminal nueralgia
A crack may involve enamel,dentin only or may involve the pulp and symptoms vary accordingly
pain occure due to fluid movement within the dentinal tubulescausing stimulation of sub-odontoblastic nerve fibres
The fluid movements are induced by pressure changes when biting with offending cusp
Close examination may disclose a crack in enamel which is better seen using dye or transillumination with fibreoptic light
Crack can be confirmed by selective biting pressure using a cooton roll or a small wooden stick to allow selective localisation of such pressure
TReated by splinting of the offending cusp with a cusp protecting restoration or by removing the split cusp and then restoration of the tooth
