Each maloccluded tooth is given a value of 1 while tooth in perfect occlusion is given a score of 0. A score of 0 will indicate a perfect occlusion; score of more than 10 would be classified as sufficient severity that would require orthodontic treatment; score between 1 and 9 would be classified as normal occlusion in which no orthodontic ...
A perfect alignment from canine to canine will yield a score of 0 on the Irregularity Index. As the crowding increases, the score will increase. Little used Dial Calipers in his study to measure the distances on a plaster model taken of mandibular arches. The caliper had an accuracy to tenths of millimeter.

Here, a selection of bones are given a score based on their perceived development, a sum is totaled based on the individual bone scores, and the sum is correlated to a final bone age. [ 4 ] [ 10 ] Lamparski (1972) [ 11 ] used the cervical vertebrae and found them to be as reliable and valid as the hand-wrist area for assessing skeletal age.
In orthodontics, a malocclusion is a misalignment or incorrect relation between the teeth of the upper and lower dental arches when they approach each other as the jaws close.
