Clinical photo of nonhealing bone after a routine dental extraction with exposure of necrotic bone. 67-year-old female with nonhealing extraction site of the lower left second molar (#18). Patient had a history of metastatic breast cancer and was receiving chemotherapy, prednisone, and zoledronate. Unfortunately, 4 months after the extraction, the site was painful with exposed bone and poor healing consistent with medication-related osteonecrosis of the jaw. Normal bone healing after a dental extraction would have shown mucosal coverage within a month
