2-2-1 Dental follicle ＊ Well-defined, unilocular, round-shaped radiolucence ＊ A well-corticated margin ＊ Surround the crown of an impact tooth ＊ Size

2-2-1 Dental follicle ＊dental follicle：a supporting tissue in the period of tooth developing ＊cap stage、bell stage ＊impaction of upper canine

2-2-2 Pericoronitis ＊locate at distal aspect of lower 3rd molar ＊extend from distal aspect of the lower 3rd molar’s crown to the ramus of mandibular bone ＊radiolucence poor-defined ＊surrouned by： soft tissue (gingiva) the crown of tooth 38.

2-2-2 Pericoronitis ＊Site：distal aspect of lower 3rd molar ＊The space for developing lower 3rd molar is not enough. ＊Failure degeneration of enamel epithelium (臨時ppt)
