Transillumination

Sometimes there is no clear indication of why a tooth is symptomatic. This radiograph shows a mandibular second molar with a moderately deep restoration (A); the pulp tests nonvital. Without any transillumination a fracture cannot be detected (B). However, by placing a high-intensity light source on the tooth surface, a root fracture can be observed on the buccal surface (C) and the distal-lingual surface (D).
