- Bohn nodules are cysts found along the facial and lingual surfaces of the alveolar ridges and on the palate away from the midline. They develop from heterotopic salivary gland tissue.
- Dental lamina cysts are found on the top of the alveolar ridges and are more common in the maxilla and mandible. They are thought to develop from remnants of the tooth bud.
