Aim: To determine the prevalence of shovel-shaped incisors and its association with the overjet in patients of 6 to 14 years and 11 months with class I malocclusion of the UPC Teaching Clinic during the period February 2011 to December 2014. Materials and Methods: The sample consisted of 900 medical records of patients treated at UPC Teaching Clinic. The measurement of overjet, age and gender was obtained from the medical records of each patient. On the other hand, the imaging x-ray analysis was performed to determine the presence or absence of shovel shaped incisors in panoramic and periapical radiographs. Finally, the chi-square test was performed to determine the association between the overjet and shovel shaped incisors. Results: The prevalence of shovel shaped incisors was 79% more frequently in women. More frequent shovel shaped incisors were located on both maxillary incisors with greater predominance in the lateral incisors. The average overjet in patients with shovel shaped incisors was 2.78mm. No statistically significant association between the shovel shaped incisors and the overjet was found (p = 0.080). Conclusions: The convex anatomy of shovel shaped incisors creates an increase in buccal – lingual volume, but it does not influence significantly, as demonstrated in this study, the measurement of the overjet. Also, it was shown the high prevalence of shovel-shaped incisors in the study sample. This finding seeks to promote future research topics about diagnosis and treatment of shovel shaped incisors and unpublished topics related to dental anthropology.
