Abstract
Objectives: To determine the relationship that could exist beteen anterior crowding and the presence of third molars. Methods: This is a cross-sectional research study. The sample consisted of study models and panoramic radiographs of patients treated in the postgraduate course in orthodontics and dental x-ray help centers in the city of Cartagena in the period between January 2011 and March 2014. We selected 365 models and panoramic radiographs of patients with complete permanent dentition, with ages ranging from 12 to 40 years, a good periodontal health, with presence or absence of bilateral lower third molars, oval shaped dental arch, models and radiographs in good shape, recently taken and mixed facial type with malocclusion class I evaluating the existing tooth bone discrepancy. Descriptive analysis was performed through frequency distribution and proportions for qualitative variables. The adjacent category ordinal logistic regression analysis was used to find relationships between different crowding categories. Results: There was no evidence of an existing relationship between anterior crowding and the presence of third molars. At the same time, it was observed that age and genre are independent of the magnitude of crowding. Also, the relationship between the position of the third molars and anterior crowding is not dependent either. Conclusions: The crowding does not depend on the presence or absence of the third molars, neither does it depend on the position of those.
