“…2 Some authors reported that anterior crowding was more frequently seen in patients with impacted third molars than patients who had properly erupted teeth. 3,4,5 Bergstrom and Jensen 6 were the first authors to analyze this effect in the developing dental arch, and they stated that there was a relationship between these teeth and changes in incisor teeth.…”

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.

Objectives: The purpose of this study was to three-dimensionally evaluate the relationship between the degree of bilateral impacted mandibular third molars (IM3M) angulation and the mandibular dental arch parameters in normal skeletal and dental malocclusion patients.Materials and Methods: In this retrospective cross-sectional comparative study, 120 adult subjects' cone beam computed tomography (CBCT) images were three-dimensionally analyzed. The sample was divided into four groups according to degree of M3M buccolingual angulation (BL°); Group A <12° on the center of the ridge (N=30), Group B 12-24° off-center of the ridge (N=40), Group C >24° off center of the ridge (N=30), and Group D (control group with normal erupted bilateral M3M).The study subjects were further also divided into three groups according to IM3M mesiodistal angulation (MD°); Group 1 from10° to 45°, Group 2> 45° and Group 3 (control group with normal erupted bilateral M3M, 0 -10°). Comparison within and between groups were performed using One-way ANOVA followed by Tukey's post hoc test, respectively. Correlation between IM3M, BL and MD angulation and mandibular arch parameter was calculated using Pearson's correlation coe cient.Results: Statistically signi cant differences (P < .001) were founded between the IM3M BL° and anterior teeth inclination, arch length (AL) and inter second molar width (inter 2 nd MW) as well as between the IM3M MD° with anterior crowding and the arch length (P < .001). Signi cant positive correlation was founded between IM3M BL° and anterior teeth inclination, and between IM3M MD° and anterior teeth crowding and inter 2nd MW. Signi cant negative correlation was observed between IM3M BL° and inter 1 st MW and 2 nd MW. Conclusion:The degree of buccolingual and mesiodistal angulation of the impacted mandibular third molars was associated with mandibular dentoalveolar changes. The increase in buccolingual angulation is associated with increase of anterior teeth inclination, and the decrease of 1 st and 2 nd inter-molars width. The increase in mesiodistal angulations was associated with increase in anterior teeth crowding and 2 nd inter-molars width.Clinical relevance: Assessment of the relationship between the impacted mandibular third molars and the degree of arch discrepancy, and the position of mandibular incisors in the three planes of space might help in the decision-making process for extraction of the impacted third molars in adult patients.
