“…Most of these researches showed that in mandibular incisors the prevalent configuration is Vertucci type I (only one canal), with a percentage ranging from 96,2% to 32,5% (mean value 64,3%). These contradictory data could be explained by the different methodologies adopted (Table 3), since only some studies were conducted with CBCT (35)(36)(37)(38)(39)(40)(41)(42)(43), and very few examined other clinically relevant parameters like confluences (44) and symmetry (45). Theoretically, there should be no significant differences between studies using CBCT or extracted teeth.…”

Background: Aim of this study was to analyze the root canal configuration in mandibular central and lateral incisors in vivo using cone-beam computed tomography (CBCT) imaging. Material and Methods: A total of 487 mandibular central incisors and 491 mandibular lateral incisors from 250 patients were examined using CBCT imaging, previously taken for diagnosis and treatment. The number of roots, root canal system configuration, presence of apical confluences, distance between confluences and radiographic root end, symmetry between left and right elements were recorded and statistically analyzed. Results: All the examined teeth presented only one root. No significant differences were found between the prevalence of two root canals in mandibular central incisors (219 teeth, 45%) compared to lateral incisors (211 teeth, 43%). Conclusions: The percentage of Vertucci type II configuration was higher than expected, being more frequent than type III. Type I was the prevalent, while other configurations were present but rare.

“…However, recent studies revealed high variation of root canal morphology among mandibular anterior teeth. 8,9 Mandibular canines, similar to mandibular incisors, have a root wider bucco-lingually than mesio-distally. Many studies reported that these teeth infrequently have two or more roots or canals.…”

“…Many studies reported that these teeth infrequently have two or more roots or canals. 9,10 Several studies have investigated root canal morphology using various diagnostic methods. 11,12 These methods include polyester resin impressions, creating transparent samples and taking radiographs in the mesiodistal and/or buccolingual directions.…”

Cone beam computed tomography (CBCT) affords high-quality image with a relatively low radiation doses and low costs. It is considered as a valuable tool in endodontic field as it determines root morphology, number of roots, canals and accessory canals. The aim of the present study was to evaluate the permanent mandibular anterior teeth canal morphology in Egyptian subpopulation. Materials and Methods:A total of 100 patients were enrolled in this study and were assigned in two groups (50 females and 50 males). In each group centrals, laterals and canines of both sides were examined (100 centrals, 100 laterals and 100 canines). CBCT Images were obtained using J Morita CBCT unit and canals were categorized into the five types of Vertucci's classification. The observer evaluated the images twice with one-week interval between assessments.Results: Type I Vertucci configuration was the most prevalent configuration in our sample and the incidence of this type was slightly higher in female than male samples. Furthermore, type III and V Vertucci configuration were slightly more in males than females. Conclusion:In the present study it was concluded that the root and root canal morphology of Egyptian subpopulation was, in general, comparable to that of other populations and that the incidence of canal variations might occur as a result of ethnicity more than gender.

“…They found that Vertucci type I and type III configurations were more prevalent in both mandibular central and lateral incisors [19]. 81.37% of teeth had a single canal and 28.43% of teeth had two canals, Type 1 Vertucci configuration was found to be the most prevalent one, and type 4 the least prevalent in the study conducted by Kamtane & Ghodke on the mandibular incisors of Indian sub population of Pune [20].…”

The current study aimed to investigate the root canal anatomy and possible variations in permanent mandibular incisor teeth (central and lateral) of an Indian subpopulation, using three-dimensional cone-beam computed tomography (CBCT) imaging in vitro. Material and Methods: A total of 200 freshly extracted permanent mandibular incisors (100 central incisors and 100 lateral incisors) were collected from dental hospitals and private clinics in Mumbai and Navi Mumbai cities from the state of Maharashtra. Teeth with fully formed apices, no calcifications, no previous endodontic treatment, absence of root fracture, absence of internal/external resorption were included in the study. The collected samples were exposed to CBCT scanning and the root canal anatomy with variations (if any) was tabulated according to Vertucci's classification for each sample. Results: Of the 200 teeth analyzed the most common root canal configuration was Type I (55.5%), followed by Type III (24.14%), Type II (12.08%), and Type IV (3%). Also, of the 111 Type I canals, 60.37% (67 off 111) presented round, while 39.63% (44 of 111) presented non-round canals in the coronal and the middle thirds. At the apical third of the canals 81.08% (90 of 111) exhibited round, whereas 18.91% (21 of 111) exhibited non-round cross-section.
