- Abstract
The high need for root canal treatments in different dental groups continues to be a challenge for professionals; since, it is necessary the knowledge of the techniques, materials, equipment and instruments, as well as of the anatomical variants on which the success or failure depends. Anatomical variations include the presence of a second root canal in lower incisors (SCRII). The present investigation is of a literature review type, articles of the type were included: literature review and descriptive studies, papers in English and Spanish were included; the search was carried out between the months of January and July 2021, in the following databases: Hinari, EBSCO host, Pubmed. The results indicate that the incidence of finding two canals in both lower incisors range from 2% to 77.9%; individually in lower central incisors the prevalence is from 11.90% to 32.50% and in lower lateral incisors, it is found between 17.50% and 58% of cases. The location of the SCRII entrance has been the subject of multiple studies, finding that there is no consensus on this point; since similar percentages have been described among the different thirds (cervical, middle and apical), an influencing factor could be ethnicity. Cone beam computed tomography has gained ground over conventional radiography and the use of magnification as the most effective diagnostic technique; however, it is suggested to carry out a study with Salvadoran patients to obtain a value that guides professionals and thus avoid endodontic treatment failures in said teeth.
