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.

Highlights

An understanding of the root canal morphology significantly reduces difficult challenges while preparing access to the cavity as well as during cleaning, shaping, and filling procedures [1, 2]
Two hundred nonfilled MB2 canals in maxillary first molars were evaluated using Ez3D (Vatech) software with different slice thicknesses: 0.5 mm, 1 mm, 3 mm, and 10 mm (Figure 1). e study included the teeth of 156 people (75 females and 81 males) aged from 20 to 73 years old
0.5 mm General Male Female is conebeam computed tomography (CBCT) study of 200 MB2 canals revealed a decrease in MB2 canals prevalence with an increase in slice thickness (Figure 2)

Summary

Introduction

An understanding of the root canal morphology significantly reduces difficult challenges while preparing access to the cavity as well as during cleaning, shaping, and filling procedures [1, 2]. Inadequate knowledge concerning the anatomy of the root canal is a major cause of treatment failure [3]. In an attempt to facilitate location of accessory canals such as the MB2 and to reduce treatment failure rates, conebeam computed tomography (CBCT) has been introduced into endodontic practices [6, 7]. It provides 3D images of the tooth structure with no destruction and enables a thorough assessment of the internal and external morphology of the root canal system [7, 8].
