Classification of odontogenic (“originating from the teeth”) cysts.
| Cyst shape | Localization |
| Radicular (“affecting the root”) cysts | At the root of the tooth |
| Follicular (“belonging to a follicle”) cysts | On impacted wisdom teeth, canines (and premolars). |
| Residual cysts (“cyst left behind after extraction (tooth removal) of a tooth affected with a radicular cyst”) | Like radicular and follicular cysts. |
| Gingival (“belonging to the gingiva (gums)”) cysts | lateral of the mandible |
| Periodontal (“belonging to the periodontium (tooth supporting apparatus)”) cysts | lower wisdom teeth |
| Pulp cysts (cysts of the dental pulp) | No preferred localization |
| Keratocystic odontogenic tumor (KCOT), formerly also called keratocyst or primordial cyst | Mandible |
