“…In the present study, all permanent mandibular incisors were single-rooted, which is in consensus with previous studies [13,14]. A literature review reveals that the prevalence of second canal in permanent mandibular incisors varies from 11.5% to 45% [15].…”

SummaryBackgroundThe aim of the study was to determine the root canal morphology of permanent mandibular incisor teeth in the Indian subpopulation with the use of cone beam computed tomography (CBCT).Material/MethodsCBCT images of 200 patients with 800 permanent mandibular incisors, fulfilling necessary inclusion criteria and aged 18 to 60 years were evaluated. The number of roots, number of root canals and canal configuration were investigated and then classified according to Vertucci’s classification of root canals. The effect of gender on the incidence of root canal morphology was also investigated.ResultsAll the permanent mandibular incisors had a single root. The majority of mandibular incisors (66.5%) had a single root with a single canal. The prevalence of second canals was as follows: right central incisor – 33.5%, left central incisor – 30%, right lateral incisors – 33.5% and left lateral incisor – 36.5%. According to gender, 15.2% of men and 20.4% of women had a second root canal. Type 1 Vertucci configuration was most prevalent, followed by type 3, type 2, type 5 and type 4 in that order.ConclusionsType 1 Vertucci’s classification (64.5%) was the most prevalent canal configuration in the mandibular anterior teeth in the Indian population. Type 5 Vertucci’s classification was the most frequently observed canal configuration of the two-canalled teeth. CBCT is an excellent imaging modality for detection of different canal configurations of mandibular incisors.

“…An accessory root canal is a common finding that occurs in the primary and permanent human dentition (Vertucci 2005, Ahmed 2013). Ethnicity, age, developmental anomalies and the formation of reparative dentine stimulated by external insults such as trauma, caries, periodontal disease and restorative procedures have been reported as contributing factors to the creation of this anatomical variation (Neo & Chee 1990, Ahmed & Cheung 2012, Han et al 2014).…”

Anterior teeth may have aberrant anatomical variations in the number of roots and root canals. A review of the literature was conducted using appropriate key words in major endodontic journals to identify the available reported cases as well as experimental and clinical investigations on accessory roots and root canals in anterior teeth. After retrieving the full text of related articles, cross-citations were identified, and the pooled data were then discussed. Results revealed a higher prevalence in accessory root/root canal variations in mandibular anterior teeth than in maxillary counterparts. However, maxillary incisor teeth revealed the highest tendency for accessory root/root canal aberrations caused by anomalies such as dens invaginatus and palato-gingival groove. Primary anterior teeth may also exhibit external and internal anatomical variations in the root, especially maxillary canines. Therefore, dental practitioners should thoroughly assess all teeth scheduled for root canal treatment to prevent the undesirable consequences caused by inadequate debridement of accessory configurations of the root canal system.

“…Some of these contributing factors resulting in such dispersion include sex(9), ethnic background [14,15] , age [16] , methodology of study (e.g. CBCT [4,[17][18][19] , clearing and injection [5,8,10,20] , MicroCT [21,22] , peripheral quantitative computed tomography (pQCT) [23] , conventional radiography [24][25][26] and clinical inspection.…”
