A 20 year old male patient reports-with the chief complaint of recurrent pain and swelling on the lingual side of the mandibular third molar area on the right side. The dental history of the patient revealed that lower right third molar was extracted by a local dentist and following this extraction, after about period of two weeks, the patient developed pain and swelling on the lingual side of the ramus. No further detailed dental history was abailable either from the patient or from the treating dentist. There were no clinical symptoms of dysesthesia of the lower lip or tongue on right side. The medical history of the patient was non-contributory.
The clinical examination was essentially restricted to intra-oral examination only. The intra-oral clinical examination revealed an absent lower third molar and tenderness on lingual side of lower third molar area on palpation.
