Micro‐CT evaluation of C‐shaped mandibular first premolars in a Brazilian subpopulation

Abstract

In this Brazilian subpopulation, C-shaped canal configuration of the root canal system was found in 67% of extracted first mandibular premolars with radicular grooves. Vertucci's types I and V were the most prevalent anatomical variations. C-shaped cross-sections were more prevalent in the middle third, and the presence of apical deltas was the most common feature in the apical third.

Micro-CT Evaluation of Root and Canal Morphology of Mandibular First Premolars with Radicular Grooves

“…In this study, the percentage frequency of C-shaped canals was high (18.57%), but within the range of 10.7% to 29% reported in the literature (9,11,13,14,16,20,28,29). In contrast, a recent micro-CT study reported C-shaped canal configuration in 67% of the mandibular first premolars with radicular grooves from a Brazilian subpopulation (30). In this study, however, radicular grooves were not classified as herein and it is possible to infer that the selected sample was composed mostly by teeth with deeper grooves, which helps to explain this higher percentage compared to the present results.…”

Root and root canal morphology of the permanent dentition in a Caucasian population: a cone‐beam computed tomography study

“…, Ordinola‐Zapata et al . ). The in vivo studies performed using CBCT usually analyse a particular group of teeth, but not all of them together (Silva et al .…”

“…, Ordinola‐Zapata et al . ). CBCT, which has a lower resolution compared to micro‐CT, is unable to capture these very small anatomic details.…”

“…One of the limitations of this research was the use of a technology (CBCT) that is not able to provide highly detailed images compared to techniques such as micro‐CT or clearing (Sert & Bayirli , Ordinola‐Zapata et al . , ). These techniques have been used to study small structures, such as apical foramina or isthmus (Zhang et al .…”

Morphological evaluation of maxillary second molars with fused roots: a micro‐CT study

“…The micro‐computed tomography (micro‐CT) imaging system is currently considered the gold standard for the study of root canal anatomy as it provides reproducible and detailed information regarding the two‐ and three‐dimensional aspects of the teeth (Ordinola‐Zapata et al . , , Filpo‐Perez et al . ).…”
