The relation of the translatory agonistic tooth movement and changes in tooth inclination may be assessed after the performed extraction of the first permanent molars since the consequences of extraction depend on the individual biological reaction of the tissue and present an individual reaction to the conditions governing this stadium of development .
where L is the length from the top of the crown to the point of hypomochlion, and a is the measured angle of tooth inclination.
2]) are the result of movement that occurred due to the change of tooth inclination [DELTA]" and translatory movement ([DELTA]') (Figure 1).
The conditions of tooth inclination were measured in panoramic x-rays, and those were angles created by vertical axes [P.
The relation, expressed by the mathematical expression, between the translatory movement and tooth inclination has been confirmed by the given results of the correlation coefficient value, but only in case of late extractions (Table 3).
According to our results, it may be said that there is mutual dependency between the changes of linear lengths and the angle of tooth inclination with late extractions.
By analyzing the significance of differences, it has been found that the change of tooth inclination does not depend on whether it refers to early or late extraction.
