(Universidad Privada Norbert Wiener, 2021-01-05) Remuzgo Ambrosio, Aymé; Mezzich Gálvez, Jorge Luis
This thesis aimed to determine the anterior displacement of the inferior dental canal in adult patients evaluated with Cone Beam CT scans in Lima, 2019. The study was observational, descriptive, and correlational, with a non-experimental design and applied approach. The population consisted of adult patients who underwent Cone Beam CT scans, with a sample of 74 scans selected. Results: The mean anterior displacement was 7.8584 mm, with a minimum of 0.00 mm and a maximum of 18.36 mm. Regarding displacement by sex, 68.9% of cases involved women, and 31.1% involved men. On the right side, the minimum displacement was 0.0 mm, and the maximum was 17.63 mm; on the left side, the minimum was 1.95 mm, and the maximum was 18.36 mm. The average displacement was 7.55 mm on the right side and 8.1601 mm on the left side, with slight differences in their means and medians (6.49 and 7.02, respectively). In terms of displacement grades, partial predominance was observed for grades 1 and 2, while grades 3 and 4 were more prevalent on the left side. Conclusion: The study found a significant relationship between the anterior displacement of the inferior dental canal and sex (p<0.05). However, no significant relationship was found between displacement and its location (right or left side) (p=0.315).

Evaluation of the distance between the lower dental canal and the apices of the lower molars in cone beam computed tomography. Lima 2023
(Universidad Privada Norbert Wiener, 2023-12-05) Alvarez Lastarria, Lourdes Alexandra; Mezzich Gálvez, Jorge Luis
The objective of this study was to evaluate the average distance between the inferior dental canal and the apices of the lower molars in cone beam computed tomography scans, Lima 2023. The methodology used was deductive, with a quantitative approach, basic type, observational, descriptive, cross-sectional, and retrospective design. The study sample consisted of 80 tomography scans from patients aged 20 to 50 years from the 'Imágenes' Radiological Center. Measurements were made using the ICAT VISION tomography software. The results showed that the average distance from the inferior dental canal to the mesial and distal apex of the first lower molar was 5.52 ± 2.21 mm and 5.05 ± 2.27 mm, respectively; for the mesial and distal apex of the second lower molar, it was 3.46 ± 2.19 mm and 2.77 ± 2.02 mm, respectively. It was concluded, using the Mann-Whitney U test, that there were no significant differences (p > 0.05) in the average distances of the first lower molar between the left and right sides, and similarly for the second lower molar between the left and right sides. Regarding sex, no significant differences were found (p > 0.05); however, for the age group, the Kruskal-Wallis H test indicated significant differences (p ≤ 0.05).

Proximity of the third molar with the inferior dental canal in computed tomographies of patients treated at the cedimax maxillofacial diagnostic center – 2020
(Universidad Privada Norbert Wiener, 2022-08-16) Lopez Bustinza, Maria Del Carmen; Ascanoa Olazo, Jimmy Antonio
The aim of this study was to determine the proximity of the third molar to the inferior dental canal in computed tomography scans of patients treated at the maxillofacial diagnostic center "CEDIMAX" – 2020. An observational, retrospective, cross-sectional, and descriptive study was conducted with a correlational level. The population consisted of 140 computed tomography scans, and an instrument validated by expert judgment was used for the evaluation.
