Eruption consists of a series of events from initiation of coronal formation and the beginning of root formation until each tooth emerges into the mouth in a specific position. Number 5 is the wolf tooth which is often extracted. In Thoroughbreds they usually arise in the mandible, and they are often in the maxilla in ponies. Eruption cysts are located on the crown of a tooth at the eruption stage at a superficial level. The eruption cyst produces a smooth, fluctuant swelling over the erupting tooth which may be either the color of normal gingiva, or pale blue.

The occurrence of this pericoronal dental lesion may be single or multiple and it seems to be more frequent than literature has reported. Site. Epithelium is thin with focal areas of proliferation forming small plaques that protrude into the lumen of the cyst. In all three disorders, abscess formation, suppurative granulomas, and finally sinus tracts are formed as a result of follicular hyperkeratinization . 0.7.

They are usually seen in first decade of life and appears as raised dome shaped swelling on the mucosa of alveolar ridge. Dr. Alpana . Odontogenic cysts are largely classified based on their location, viability of the associated tooth and clinical setting. stratified epithelium with "ribbon-like appearance" with palisaded basal cell layer, parakeratosis, artefactual separation of epithelium from the basement membrane.
