A Clinical Challenge & Solution: Detecting Cracks in Teeth Using PTR-LUM-The Canary System; A Case Report

Detecting cracks in teeth is a clinical challenge. Patients may complain of diffuse pain on chewing, no pain on temperature change and pain that occurs episodically. Common diagnostic tools such as radiographs and visual examination may not detect cracks. This case study shows how PTR-LUM in The Canary System can detect cracks in teeth not seen with other devices. In this clinical situation, the crack involved a large part of the mesial and distal surfaces of a mandibular second molar.
