There was mild bleeding on manipulation (Figure 1).
(A) OPG revealing an area of moderately well-defined radiolucency on the left posterior mandibular alveolar ridge distal to 75 with a discontinuous sclerotic margin; a speck of calcified mass was evident on the pericoronal region of the developing 36; (B) IOPA radiograph in the area revealed a soft tissue shadow and evidence of calcification with radiodensity similar to dentin

The developing tooth bud of 36 was inferiorly displaced (Figure 2A). Intra oral periapical radiograph in the area revealed a soft tissue shadow and evidence of calcification with radiodensity similar to dentin (Figure 2B).
(A) H&E 40X & (B) H&E 100X: histopathological section revealing spindle cells in fascicles and parallel to blood vessels at places; typical 5-10 mitosis/10 hpf were seen with no abnormal mitotic figures

The section from the soft tissue attached to the tooth showed rests of odontogenic epithelium surrounded by mesenchymal tissue and dentin (Figure 3A, Figure 3B).
