Abstract

Abstract: Objective To explore root resorption of third molars after long-distance mesial movement through retrospective study on mandibular first molar extraction cases and to compare the effect of root development of the third molars on root resorption. Methods Thirty-two cases of mandibular first molar extraction were analyzed retrospectively, and 41 mandibular third molars were included in the study. According to root development of the third molars, they were divided into group A (root development completed) and group B (root development not completed). Length of the root was measured by direct digital panorama before and after treatment. Changes of the root at different development stages were studied after long-distance mesial movement. Results In group A, the mesial and distal roots absorbed (0.07±0.66) mm and (0.09±0.62) mm respectively, and the difference was not statistically significant (P>0.05). In group B, the third molars continued to develop and the length increased after correction,and the difference was statistically significant (P<0.05). The distance of mesial movement of mandibular molars in group B was greater than that in group A (P<0.05). There was no significant difference in the length of mesial roots between group A and group B (P>0.05) after treatment. The length of distal root in group B was longer than that in group A, and the difference was statistically significant (P<0.05). Conclusion The root resorption of mandibular third molars after long distance mesial movement is small and generally has no clinical significance. Root development has a certain impact on the distal root, suggesting that loss of mandibular first molars should be treated before the completion of root development of mandibular third molars.
