case_images: Inter-radicular lucency extending to the periradicular area was indicative of the treatment failure (Figure 1A).  After radiographic checking (Figure 1B), chlorhexidine mouthwash was prescribed and the patient was dismissed. After six months, the tooth was asymptomatic and radiographically checked (Figure 1C). After 12 months, the tooth was in complete function and the inter-radicular bone healing had occurred (Figure 1D).
