Observation
The oral examination of a 26-year-old woman revealed a left partially impacted mandibular molar responsible for pain and infection. Although it was assumed it was a third molar, the panoramic radiograph showed that the real third molar was completely impacted and that two partially impacted mandibular fourth molars were present bilaterally. Both of them were removed without complications and the left third molar was extracted after fragmentation to avoid any injury of the contiguous inferior alveolar nerve.
