Introduction: Eruption is a dental development process responsible for movement by the dental germ to its final position, when it occludes with its opposite. Interaction is defined as dental eruption failure caused by a physical obstacle in the path of access or eruption towards a normal tooth position. The teeth with the greatest tendency towards impaction, in order of frequency, are the third molars, followed by the canines, pre-molars and secondary molars. The purpose of this research is to determine the frequency of impaction of the second inferior molar in patients at the clinics of the Dental Faculty of the Universidad de Antioquia.

Methods: A retrospective descriptive study was carried out at the Dental Faculty of the Universidad de Antioquia. 500 medical histories of patients between the ages of 6 and 16 who had used the clinics of that faculty over a six-year period were analyzed.

Results: 442 Medical histories fulfilled the inclusion criteria. The average age of the sample was 10.8; 57.2% were females. 48 patients were found to have impacted second molars (10.8%), 30 of whom were females (62.5%). In most cases, the impaction was bilateral, (80%) and mesial inclination was 76.6%. Among men, bilateral impaction predominated, accounting for 83.3%, along with mesial inclination, at 88.8%.

Conclusions: In comparison with other studies, a high frequency of impaction was found, thus underlining the importance of early diagnosis.
