[Complex treatment of a large radicular cyst due to traumatic dental injury--a case report].

A 28-year-old male came to the clinic for control visit and scaling. Panoramic radiograph was taken before any treatment. The radiograph revealed a large size periapical lesion extending from the lower right first premolar to the lower left canine. History of dental trauma in childhood was recorded. The asymptomatic, injured teeth were not treated by dentist. Upon clinical examination a discolored lower right central incisor and more teeth with pulpal necrosis were found. After the endodontic treatments a cystostomy was performed. Obturator was used by the patient in the healing period. The success of complex treatment is proven by the highly recovered bone forming shown during the regular recalls. For the correct diagnosis and planning of the complete treatment dentist should be careful on general- and dental anamnesis and complete clinical and radiographic examination. Small clinical signs and pathoses should alert the dentist. This case is a reminder that the careful anamnesis, clinical examination and early diagnosis of any pathosis are very important.
