The third molars can adopt a diversity of possible positions during the process of eruption. These positions make them appear as pieces included, retained or impacted, problematic associated with mechanical disorders such as obstruction of soft or hard tissues, or embryological reasons. A descriptive, cross-sectional study with a mixed approach was carried out in order to characterize the ways of presenting this type of teeth in the subjects of the study. The population was determined by the totality of patients treated for symptoms related to the presence of included and impacted third mandibular molars (164) in the Dental Service of the General Hospital of Riobamba between January and December 2015. 103 patients aged between 15 and 60 years were selected through a non-probabilistic sampling of the intentional type, considering some aspects like optimal mental health status and radiological diagnosis in retained third molar clinical history. The morphological characteristics of the observed third molars are close to the anatomical descriptions given by science, predominantly the vertical inclination of the longitudinal axis with respect to the second molar. The presence of this anomaly was observed mainly in the male sex and in the age group formed by adolescents and young adults who did not report having a family history of pathologies related to this condition.
