1A. Radiograph (2006) showing a well-defined unilocular radiolucency located between the right mandibular first premolar and second molar. 1B. Radiograph (January 2007) showing bone-like radiopacity in the original radiolucency between the right mandibular first premolar and second molar. Note a new unilocular radiolucency appears to have formed in the right mandibular canine region. 1C. Radiograph (November 2007) showing bone-like radiopacity in the right mandibular canine region. A recurrent radiolucency has emerged between the right mandibular first premolar and second molar extraction socket and second molar. 1D. Radiograph (June 2008) showing bone-like radiopacity in the right mandibular canine region. A recurrent radiolucency has emerged between the right mandibular first premolar and second molar extraction socket and second molar.
