Second Mesiobuccal Canal Evaluation Features with Cone-Beam Computed Tomography

Abstract

Aim. The aim of the study is to evaluate the difference in MB2 prevalence with different slice thicknesses in maxillary first molars. Materials and Methods. Two hundred nonfilled MB2 canals in maxillary first molars of 156 people (75 females and 81 males) aged from 20 to 73 years old were evaluated with CBCT with different slice thicknesses: 0.5 mm, 1 mm, 3 mm, and 10 mm. A general analysis was performed out, as well as in the age groups and on gender groups. Results. Visualization with 0.5 mm and 1 mm slice thicknesses was 100% and generally equal, in both the male and the female group. General MB2 visualization with 3 mm slice thickness was 42% and 29% for the male group and 27% for the female group. No canals were visualized with 10 mm slice thickness. The study did not demonstrate a statistical difference in the MB2 prevalence between gender and age groups with the 3 mm slice thickness. Conclusion. The most valuable way to evaluate the root canal system in first maxillary molars with CBCT is using 1 mm slice thickness for both genders and every age group.

Radiological and Morphometric Features of Canalis Sinuosus in Russian Population: Cone-Beam Computed Tomography Study

“…However, several studies demonstrated different conclusions on the dependence of the slice thickness of CBCT scans and the detection of the anatomical and other structures, as well as the way that reduces artefacts [18][19][20][21][22][23][24]. Our choice of slice thickness was 1 mm for good and moderate detection of CS without missing it and with high reduction of artefacts in this case.…”

“…15 Additionally, Mordanov et al conducted a study in Russian patients and stated that no significant correlation could be found between sex, age, and race and the prevalence of MB2 canal. 31 Using an operating microscope, Das et al discerned no significant difference in the prevalence rate of MB2 canal according to age, sex, or side. 32 Falcão et al also reported no significant differences in the existence of MB2 canal according to age and sex.…”

“…el uso de este software promete ser un avance significativo en la endodoncia moderna, minimizando errores en la práctica clínica en cuyos casos la anatomía radicular presenta cierta complejidad. 6,15,[20][21][22][23][24][25][27][28][29][30][31][32][33][34][35][36] El no encontrar diferencia significativa en los resultados puede ser una muestra de cierto grado de simetría anatómica entre los conductos mesiovestibular y mesiolingual, aunque eso no significa que existan casos donde las variantes anatómicas entre ellos sean mayores; esto puede tener correlación con estudios de caracterización morfológica donde se ha observado simetría bilateral en la morfología oclusal de molares inferiores. 37…”
