case_images: On extraoral examination, a swelling was seen in the left maxillary region measuring approximately 3 cm x 3 cm and was roughly spherical in shape [Figure 1].
case_images: Orthopantomogram shows a well-defined unilocular radiolucent lesion extending from the mesial surface of 63 to the unerupted 26, absence of developing tooth bud of 24 and 25, oval radio-opacity (arrow). Intraoral periapical in the inset shows grossly carious 64 and 65

case_images: On radiological examination, a well-defined unilocular radiolucency extended anteroposteriorly from the mesial surface of 63 to the unerupted 26 and superio-inferiorly, from developing 23 to the carious 64 and 65 [Figure 2].

case_images: Hard tissue (crypt/dome like structure) (decalcified section and ground section): The inner thickness of the crypt showed predominant presence of longitudinal and cross cut dentinal tubules like structure [Figure 5].
case_images: Photomicrograph showing an arrangement resembling dentinal tubules merging with haversian canal (H&E stain, x100)

case_images: Moving to the outer thickness of the crypt, areas of transversely cut dentinal tubules were seen merging with haversian canal [Figure 6].

case_images: The outermost thickness of the crypt showed predominantly lamellated bone like arrangement with the presence of concentric lamellaes and haversian canals [Figure 7], thus speculating attempted tooth formation.
case_images: Photomicrograph showing odontogenic epithelium with presence of columnar ciliated cells (H&E stain, x100)
