Variaciones anatómicas del sistema de conductos radiculares en incisivos inferiores permanentes observados mediante tomografía computarizada de haz cónico y micro tomografía computarizada entre 2010-2020. Scoping Review

Abstract

Introduction: Knowledge of the anatomy of the root canal system is a determining factor to avoid incurring an incomplete instrumentation of the root canal and thus avoid the lack of elimination of the bacterial etiological factor, which causes the pulp and periapical pathology. The method of examination and the classification of morphological variations influence the success of the treatment. Aims: describe the anatomical variations of the lower incisor root canal system classified and reported in studies; using cone beam computed tomography and micro computed tomography between 2010 and 2020. Materials and Methods: A Scoping review-type study of secondary sources was carried out,the literature search was carried out in four medical databases: PubMed, EBSCO, ScienceDirect and Scopus. 413 articles were collected, of which 35 studies were used for qualitative synthesis and 30 for quantitative synthesis. Results: Cone beam computed tomography (CBCT) was the most used method with 87.5%, the most used classification was Vertucci, with 77.5% and the most frequent configuration was type I with a mean of 67.74 (SD 16.95) for the central incisors and a mean of 64.72 (SD 14.73) for the lateral incisors. Likewise, other morphological variations were evidenced such as type III, II and V configuration. Conclusion: Asia was the continent with the highest number of publications, for its part; in Colombia no studies were found showing a gap in knowledge in the country.
