Panoramic radiograph of<unk>  lower<unk>  teeth (green arrows) in a 26-year-old with dental caries (red arrows) on the adjacent teeth The diagnosis of impaction can be made clinically if enough of the<unk>  tooth is visible to determine its angulation, depth, and if the patient is old enough that further eruption or uprighting is unlikely.<unk>  teeth continue to move to the age of 25 years old due to eruption, and then continue some later movement owing to periodontal disease. If the tooth cannot be assessed with clinical exam alone, the diagnosis is made using either a panoramic radiograph or cone-beam CT. Where unerupted<unk>  teeth still have eruption potential several predictors are used to determine the chance of the teeth becoming<unk> . The ratio of space between the tooth crown length and the amount of space available, the angle of the teeth compared to the other teeth are the two most commonly used predictors, with the space ratio being the most accurate. Despite the capacity for movement into early adulthood, the likelihood that the tooth will become<unk>  can be predicted when the ratio of space available to the length of the crown of the tooth is under 1.
