case_images: A small bony window of approximately 5 mm x 5 mm was made within the portion of labial plate that corresponded to the upper right central incisor. An incisional biopsy was performed and a histological diagnosis of dentigerous cyst with nonkeratinized epithelial lining and fibrous connective tissue was made [Figure 3].
