Correlation between the Etraction of Permanent Teeth in Children and Future Growth of Third Molar

Author(s): Rusul A Alsaray*


Background: permanent molar (M3) formation, morphology, and agenesis vary greatly between individuals. This study examines how removing the lower first permanent molar affects the position and angle of the developing third molar in 7- to 10-year-olds.
Method: Radiographs of Two groups from southern Iraq were identified: those who had one or more first permanent molars extracted between ages 7 and 10 and those who did not. Both groups had panoramic radiographs taken at 8.5 and 10 years before extraction. 80 third molars were extracted, and 50 had retained first permanent molars. Comparing groups used independent sample tests.
Results: The third molar moved significantly more mesially in the group of extraction (P<0.05), and the angle righted itself significantly more in the group of extraction than it did in the group of non-extraction (P<0.05). Both of these results were significantly different from what was seen in the group of non-extraction. These two findings presented a striking contrast to the findings obtained from the control group that did not undergo extraction. When it came to the movement of the third molar downward, there's not a statistical significant difference between two groups in terms of a vertical movement of the 3rd molar.
Conclusion: An extraction of the lower first permanent molar encouraged mesial movement and up righting of the developing third molar while the dentition was still in the process of developing. Because of this, the probability of the third molar erupting in the future may increase.
