Análisis de variaciones anatómicas de incisivos inferiores permanentes mediante estudios tomográficos Dentaimagen 2018.

Abstract

Introduction: In today’s society, the endodontic treatment is of great importance for the preservation of dental pieces, which otherwise would be affected by the attack of external agents. Therefore, it is essential to perform a correct chemical-mechanical preparation, which could be difficult in some cases, due to the anatomy of the root canal. Objective: To determine the anatomical variations of permanent lower incisors and their relationship with anatomical structures through tomographic studies. Materials and Methods: A transversal descriptive analytical research was performed, where 68 tomographies performed in 2018 were analyzed in the DentaImagen Radiological Center. 32 male patients and 36 female patients between the ages of 11 to 87 were selected according to our inclusion and exclusion criteria. Results: The incidence of a duct was 79.23%, and 20.77% had two ducts. We found 5 types of Vertucci configurations, where Type I was the most frequent (79.23%), followed by Type III (15.38%). The most frequent conduit shape was round (50%), followed by the oval shape (29.23%). The average length of central incisors was 19.37mm, and the lateral incisors were 21.08mm. Conclusion: We can conclude that the incidence of a duct in the lower incisors analyzed was significantly higher than lower incisors with two ducts, with a higher prevalence for males. It was also found that the Vertucci l and lll types, and the rounded shape of the ducts, were the most common. There were no significant differences between men and women.
