Abstract
Buccal bifurcation cyst (BBC) is a rare inflammatory odontogenic cyst, which commonly affects children in the first decade of life. We report a case of a seven-year-old healthy boy with bilateral BBC, which involved unerupted incomplete permanent mandibular first molars. A review of the literature in English language revealed few similar cases. We reviewed 16 manuscripts of bilateral mandibular BBC, reporting a total of 20 cases since 1970. The clinical features of bilateral mandibular BBC summarized here could assist specialists with an accurate diagnosis and provide patients with optimal management.

Summary
We report a case of a seven-year-old healthy boy with a chief complaint of painful, slowly growing lower jaw swellings on both right and left sides consistent with bilateral BBC, which involved unerupted incomplete permanent mandibular first molars. A panoramic radiograph illustrated bilateral, well-defined radiolucencies surrounded by sclerotic margins and including the unerupted incomplete permanent mandibular first molars (36 and 46, according to the FDI World Dental Federation Notation). The panoramic image showing right radiolucency measured around 1 cm in its greatest dimension, and involved the unerupted permanent mandibular first molar (46, according to the FDI World Dental Federation Notation), and not involving the inferior mandibular cortical bone and the adjacent areas. The left radiolucency measured around 3cm in its greatest dimension, and involved the unerupted permanent mandibular first molar (36, according to the FDI World Dental Federation Notation), the inferior mandibular cortical bone and the adjacent areas. No clinical evidence of lesion recurrence, and radiographic imaging illustrated that the affected areas were completely filled up with bone
