“…To date, most investigations have only focused on the posterior dental group [ 1 , 2 , 5 , 6 , 7 , 8 , 9 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 19 ], as this is the most anatomically complex and further compromises the complete removal of the radicular pulp. The relevance that researchers give to the first deciduous molars is striking, as six studies focused only on that tooth [ 5 , 6 , 7 , 8 , 11 , 19 ].…”

“…Only one in vitro study surpassed ours in this aspect [ 8 ]. In most of them, the number of molars analyzed was less than 132 dental units [ 1 , 2 , 5 , 6 , 7 , 9 , 11 , 13 , 14 , 15 , 23 ] oscillating the range between 20–90 teeth.…”

“…The exhaustive knowledge of pulp anatomy, especially root canal, increases the prognosis and success of pulp therapies, because the primary teeth have a highly complex root canal system. The capricious and variable anatomy, which has numerous accessory, reticular and recurrent canals, and apical delta ramifications, is not clinically appreciable with radiographic techniques, because the superimposition of the mineralized structures makes it impossible to observe faithfully in the buccolingual/palatal direction [ 2 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

Pulp therapy in primary teeth is a challenge for a dentist, therefore, a better understanding of the anatomical characteristics of this tissue is essential to remedy these deficiencies. The aim of this study was to determine the morphological peculiarities of the root canals of extracted deciduous molars by Cone-Beam computed tomography (CBCT). As such, healthy molars without physiological resorption were collected and sanitized. After analyzing descriptive and inferential statistics, the results show that 56% of lower molar roots have a Weine’s type III canal configuration; the upper and lower second molars are significantly larger compared to the first, with a mean of 8.318 (±1.313) mm and 7.757 (±1.286) mm, respectively. Additionally, the palatine canals exhibited greater volume than the others, with a mean of 3.687 mm3. There are multiple discrepancies in the molars that have been studied in other investigations. The presence of a supernumerary root in the mandibular molars, a smaller dimension of the root canals and a more evident apical angulation are more obvious. The discovery of great anatomical versatility in the posterior dental group is an aspect applicable to root therapy.

Background. A thorough knowledge of root and root canal morphology in primary dentition is essential for success of endodontic therapy. This information also finds importance in anthropological research in reconstructing human population history. Lack of studies of root and root canal morphology in mandibular anterior teeth prompted us to the present study. Methods. A total of 109 extracted primary mandibular incisors and canines were collected, out of which 90 teeth were selected for this study and divided into 3 groups: CI, mandibular central incisor; LI, mandibular lateral incisor; C, mandibular canine. All the sample teeth were scanned using cone beam computed tomography (CBCT). Number of roots, number of root canals, length of root, mesiodistal (MD), and buccolingual (BL) width of canal, shape of canal, and presence of accessory canals were assessed. Collected data were statistically compared using one-way ANOVA and chi-square tests. Results. All teeth studied displayed single root with single root canal conforming to type I Vertucci’s classification. Root length of CI was significantly shorter than both LI and C, with no significant difference between LI and C. Straight root canals were more common in CI and LI, whereas curved canals were more common in C. S-shaped canals were seen in a few CI and C. BL canal width was more than MD width in all teeth, C showing significantly larger dimensions than both CI and LI. Conclusion. This study presents root and root canal characteristics of primary mandibular central incisor, lateral incisor, and canine in children from Indian ethnicity.
