Secondary r tention refers to the cessation of eruption neither due to a physical barrier in the path of eruption nor as a result of an abnormal position.The criteria currently used to diagnose secondary retention are confusing and often not reliable. The etiology of secondary retention is essentially unknown, but ankylosis has been suggested as being the main factor.
