Anatomical determination of the ducts mesio-vestibular roots, through diaphanization in the Peruvian population
(Universidad Privada Norbert Wiener, 2022-09-29) Torres Zelada, Cretta Tamina; Llerena Meza De Pastor, Verónica
The objective of this research was to determine the anatomical constitution of the mesio–vestibular root canals through diaphanization in the Peruvian population. This was an in vitro study using 61 teeth (lower molars). The methodology was hypothetical-deductive, with a quantitative approach, descriptive type, and observational, descriptive, and comparative design. Results: According to Vertucci's classification, in an in vitro test of 61 teeth, the results showed that 50% (30 teeth) belonged to Type I with one canal, followed by Type III with one canal at 25% (15 teeth). The third group was formed by Type IV with two canals at 8.33% (5 teeth), and the fourth group was Type V with one canal at 6.66% (4 teeth). Conclusions: The prevalence of Type I was determined, indicating the anatomical variety of root canal types present in the roots of the first lower molar in the Peruvian population, according to Vertucci’s classification. It was determined that there is a prevalence of anatomical variety in the direction of mesio–vestibular root canals in the Peruvian population. Additionally, it was concluded that lower molars with a single root canal are the most frequent in the Peruvian population.

Anatomical variants of root canals in mandibular second molars evaluated in Cone Beam tomography in a dental imaging center
(Universidad Privada Norbert Wiener, 2023-04-19) Pareja Maldonado, Maria Lizbeth; Llerena Meza De Pastor, Verónica
The anatomical variations of the root canals in mandibular second molars were determined through Cone Beam CT scans in a dental imaging center. The study was observational and quantitative, with 108 Cone Beam CT scans being studied using the Vertucci and Melton classifications. It was found that the majority of patients had 2 roots on the right side (77.80%) and left side (84.30%). There were 3 canals on the right side (68.50%) and left side (75.90%). Regarding the Vertucci classification for the mesial root, type II was found on the right side (26.90%) and type III on the left side (32.40%). In the distal root, type I was found on both the right side (92.60%) and left side (92.60%). In terms of sex, most female patients presented type I on the mesial root on the right side (16.70%) and type III on the left side (19.40%). The distal root was type I on the right side (50.90%) and left side (50.90%). Regarding the prevalence of the C canal, the right and left sides showed 24.10%. Type I was mostly found on the right side (61.50%) and left side (65.40%), with a higher prevalence in females. In conclusion, there is anatomical variation in the root canals of mandibular second molars.
