The Impact

Estimates show that the prevalence of mandibular dental anterior crowding is high and might be up to 40%. The etiology of the condition has been multifactorial and evidence regarding the impact of mandibular third molars is still controversial. We discussed the potential role that impacted teeth (particularly mandibular third molars) might have in developing dental arch crowding. Evidence from different original studies and reviews regarding the impact of lower third molars on dental crowding was controversial. However, most of these studies showed that the correlation between these events was insignificant and additional studies might be needed for further validation. We have also identified many factors that can lead to dental arch crowding among the relevant studies in the literature. These factors might include general factors (including gender and age), skeletal factors (including malocclusion and growth of jaws) and dental factors (including primary tooth loss and tooth crown size), all of which were extensively discussed in the current study. Accordingly, further attention should also be paid to studying these factors.

Objective: To compare the opinion of orthodontists and oral-maxillofacial surgeons on relation between erupting mandibular third molars and lower incisal crowding.Patients and Methods: This descriptive study involved 100 Pakistani clinicians (50 orthodontists, 50 oral-maxillofacial surgeons) to answer online questionnaire regarding their opinions on link between erupting Mandibular Third Molars along with their extraction opinion with reference to development and prevention of lower incisal crowding. Data was analyzed using SPSS version 21.0. Pearson's chi-square test was applied and statistical significance was defined at <=0.05.Results: Statistically insignificant differences were found between oral-maxillofacial surgeons and orthodontists regarding question of erupting mandibular third molars in causing lower incisal crowding. Similarly, statistically insignificant differences between oral-maxillofacial surgeons and orthodontists were found regarding question of recommending preventive extraction of mandibular third molars for developing lower incisal crowding.Conclusion: No opinion differences were observed between Pakistani oral surgeons and orthodontists, regarding the link of lower third molar as a cause of lower incisal crowding.

Abstract Objective: To test the hypothesis that there is a relationship between forward mandibular third molar migration and root curvature of the mandibular third molars. Materials and Methods: The study is comprised of 64 patients who had a history of unilateral mandibular first molar extraction before 16 years of age with no other missing teeth or prosthetic restorations in the mandible. The extraction space was fully or partly closed. The mean remaining space was 1.1 ± 0.41 mm. The root angles for the mesial and distal roots of the mandibular third molars were measured on the panoramic radiographs by calculating the differences between the angle formed by the long axis drawn perpendicular to the occlusal plane of the crown of mandibular third molar and the central line of the lower one ninth of the root through the root apex. The differences between the extracted and nonextracted sides for mesial and distal roots were analyzed using a paired sample t-test. Results: Both mesial and distal roots were approximately 8° more vertical on the extraction sides than on the nonextraction sides. The differences were statistically significant. Conclusion: Mesial tooth migration of mandibular third molars reduces the amount of root curvature developing on this tooth.
