When this article was originally published, the caption for Figure 1 incorrectly referenced the lower left second molar/third molar instead of the lower right second molar/third molar. The correct figure caption is included below:

Fig. 1 An OPG radiograph showing diffuse radiolucency around the roots of the lower right second molar with loss of the lamina dura and widening of the periodontal ligament space. The extraction socket is visible following removal of the lower right third molar, initially thought to be the cause of the symptoms.
