Body<br />

Objective and Methods: Bifid mandibular condyle (BMC), which characterized by the duplication<br />

of the mandibular condyle and a groove between these two condylar heads, is an<br />

uncommon anomaly with an unknown etiology and uncertain pathogenesis. Although some<br />

circumstances such <strong>as</strong> trauma, teratogenic drug use, genetic tendency, infection and exposure<br />

to radiation may be responsible for these variations, the most likely theory is traumatic origin<br />

such <strong>as</strong> the application of forceps during birth, condylar fracture resulting from an accident<br />

or surgical condylectomy. BMC c<strong>as</strong>es are incre<strong>as</strong>ingly being detected with the incre<strong>as</strong>ed use of<br />

panoramic radiographs and advanced imaging techniques, especially computed tomography<br />

(CT), cone beam CT and magnetic resonance imaging.<br />

Results and Conclusion: In this report incidentally bilateral BMC c<strong>as</strong>e of a five year old girl<br />

referred to our clinic with the complaint of tooth ache w<strong>as</strong> presented. From the anamnesis,<br />

the head trauma due to an accident at the age of two and consecutive condyle operations w<strong>as</strong><br />

revealed. In the clinical examination no objective symptom <strong>including</strong> limitation in the mouth<br />

opening, TMJ dysfunction, pain, sound, or <strong>as</strong>ymmetry were observed. Pre - and post operative<br />

CT examinations were obtained from her medical records. Similar to most BMC c<strong>as</strong>es the<br />

patient w<strong>as</strong> <strong>as</strong>ymptomatic and diagnosed <strong>as</strong> an incidental finding during routine radiographic<br />

examination. Hence, panoramic radiographs and other conventional radiographic techniques<br />

are sufficient in <strong>as</strong>ymptomatic c<strong>as</strong>es. However, in patients with clinical symptoms, advanced<br />

imaging techniques such <strong>as</strong> CT, CBCT and MRI should be performed in order to support diagnosis<br />

and treatment planning.<br />
