Abstract

AIM: This study aims to investigate effect of mandibular third molars on angulation of mandibular second molars and canines.
 MATERIAL AND METHOD: A total of 16 patients (10 female, 6 male) were included. All patients had two panoramic radiographs. All mandibular third molars were available in the first panoramic radiograph. The second panoramic radiograph was taken approximately 124.81 ± 21.63 weeks after one-sided mandibular third molar extraction. The angulations of the second mandibular molars and mandibular canines were measured on the first and second panoramic radiographs. These angulations were evaluated on the extraction side and non-extraction side. Paired t-test was used to compare the angulation changes.
 RESULTS: On the extraction side, differences were observed in the angulation of the second molars and canines showed uprighting movement however, these differences were not significant. On the non-extraction side, both the second molars and canines showed uprighting movement. However, the difference was statistically significant only in the second molars.
 CONCLUSION: We conclude that mandibular teeth are progressively uprighting and not extracting the mandibular third molars increases the uprighting effect on the second molars.
