“…Micro-computed tomography is able to provide accurate and quantifiable results, thus, is considered as the gold standard when investigating RCCs 18 . However, relative few studies have investigated the MaCa root canal morphology by means of micro-computed tomographic imaging 12 – 14 , 29 . The RCC description systems proposed by Vertucci 19 and Weine et al 3 have been widely reported in the literature.…”

The aim of this study was to investigate the root canal system morphology by means of a root canal configuration (RCC) classification described with a four-digit system, the physiological foramen geometry and accessory canal frequency and morphology, of 101 mandibular canines (MaCa) of a Swiss-German population by means of micro-computed tomography. Micro-CT examination of the MaCa was performed and the obtained images analyzed with a 3D imaging software. In single-rooted MaCas, the most frequently observed RCCs were 1-1-1/1 (74.5%) and 1-1-1/2 (14.3%). Seven other RCCs were less frequently observed with a frequency from 4.1 to 1.0%. One physiological foramen was observed in 80.6% of the MaCas, two in 16.3%, three in 1.0% and four in 2.0%. Accessory and connecting canals were apparent only in the middle and apical root thirds. Two-rooted MaCas occurred less frequently (n = 3). When one physiological foramen was present, the mean size of the narrow and wide diameters were 0.28 mm (± 0.07) and 0.40 mm (± 0.11), while the distance between physiological and anatomical foramen was 0.45 mm (± 0.17). MaCas are predominantly single-rooted teeth with a 1-1-1/1 or 1-1-1/2 RCC. Most MaCas had one physiological foramen with an oval shape.

“…Although CBCT images do not provide images that are as high-resolution as those of micro-CT, it appears to be a good method to examine root canal configurations [ 3 , 43 ]. Few studies have investigated the MaCa root canal morphology by means of micro-CT [ 33 , 34 , 37 , 38 ]. However, those investigating morphological parameters different from the ones in the systematic review investigated other topics than root canal configuration; thus, they did not meet the inclusion criteria and could not be considered in the present study.…”

“…Cone-beam computed tomography (CBCT) and micro-computed tomography (micro-CT) are the two most recently introduced investigation methods, and CBCT has been predominantly used for in vivo investigation of the morphology of the root canal system of mandibular canines (MaCa) [ 6 , 13 , 14 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. Although micro-CT has already been used to examine various teeth as well as to describe the internal morphology of mandibular canines, it has not yet been used to identify the root canal configuration [ 3 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ].…”

The aim of this study was to systematically review the root canal morphology and configuration (RCC) of mandibular canines (MaCa). The review was registered in the PROSPERO database (ID-272297) and it was carried out following the PRISMA guidelines. Three electronic databases (MEDLINE via PubMed, Embase, Scopus) were searched. Randomized controlled trials, cross-sectional, cohort, comparative, evaluation and validation studies have been included. The anatomical quality assessment (AQUA) tool was used for a quality assessment of the anatomical studies. Of 910 studies retrieved from the systematic search, 28 studies investigating RCCs were included. Most MaCa were single-rooted (87.9–100%), while two-rooted MaCa were present up to 12.1%. The 1-1-1/1 (35.8–96.4%) was the most commonly reported RCC, followed by 2-2-1/1 (0.2–22.0%) and 1-2-1/1 (0.9–20.0%). A high frequency of 1-1-1/1 RCC in MaCa has been described. Most systematic review reports confirm that two-rooted MaCa are found considerably less frequently than single-rooted ones.

“…Over the years, several methodologies have been used for the study of the internal root anatomy of mandibular incisors (MI), including canal staining and tooth clearing (2)(3)(4)(5), radiographs (6)(7)(8)(9)(10), cone-beam computed tomography (11)(12)(13)(14)(15)(16)(17)(18)(19) and high-resolution computed tomography (20)(21)(22).…”

Comparative study of Vertucci and Ahmed classifications to evaluate the main root canal configuration of mandibular incisors in a Brazilian population

et al. 2021

View full text Add to dashboard Cite

This study aimed to compare the main root canal configurations of mandibular incisors (MI) in a Brazilian population using Vertucci and Ahmed et al. classifications. One hundred and sixty‐five human permanent MI were scanned using a micro‐CT. Two examiners classified the samples according to Vertucci and Ahmed et al. classification. Kappa coefficient was employed. The majority of MI had a single root canal (52.1%). Type III Vertucci and 1MI1‐2‐1 Ahmed et al. was the most common 2‐canal MI (20%). In the apical third, the presence of one, two and three canals was found in 81.8%, 15.2% and 3% respectively. In the cervical and middle thirds, one, two and three canals were found in 86%, 12.2% and 1.8% respectively. Ahmed et al. classification was able to classify the entire sample studied, whereas 11 teeth (6.66%) did not fit Vertucci’s classification.
