The purpose of this study is to evaluate the morphological characteristics of the roots and roots canals of primary molar teeth using Cone-Beam Computed Tomography (CBCT).<br/>A total of 68 CBCT images of children aged 4 - 5 years was used for this study. A total of 160 molar teeth were analyzed. Various parameters such as the number of roots and canals, length of root and root canal, and the angulation and shape of the roots were analyzed.<br/>All maxillary primary molars had 3 roots. The presence of 2 root canals in 1 root was only observed in the mesiobuccal root of maxillary primary second molars. Most mandibular primary molars had 2 roots, and most mesial roots had 2 root canals.<br/>Concerning the length of the roots, the palatal root of the maxillary primary molar was found to be longest whereas the distobuccal root was shortest. In mandibular primary molars, the mesial root was longer than the distal root. In maxillary primary molars, the palatal root had the greatest angulation whereas the distal root has the greatest in mandibular molars. The root and root canals of maxillary primary molars were more curved in shape whereas mandibular primary molars were straight.

Abstract Objectives To elucidate age-related changes in the root canal morphology of primary molars and determine new indices to detail the root canal anatomy by cone-beam computed tomography (CBCT).Materials and Methods CBCT data of primary molars from 57 children aged 3–8 years without systemic diseases that affect tooth development were collected. The following indices were defined and calculated using Mimics 17.0, 3-Matic 9.0, and ImageJ software: (i) the cross-sectional area of the root canal; (ii) R.15: the proportion of the lateral canal wall with an inner diameter less than 0.15 mm; (iii) LC/LR: the ratio between the canal length and root length; and (iv) Ndis: the discontinuous canal count. Correlation analysis and binary logistic regression were performed to assess the variants and age-related changes in canal morphology.Results On CBCT analysis, the cross-sectional area of the root canals for mesiobuccal (MB) roots, palatal (P) roots and distobuccal (DB) roots was negatively correlated with age (P<0.05), with a correlation coefficient of -0.41, -0.42, and -0.26, respectively. The R.15 of MB roots was positively correlated with age (P<0.05, rs=0.39). The value of LC/LR for MB, DB, and P roots decreased with age, with a correlation coefficient of -0.39, -0.42, and -0.29, respectively (P<0.05). The risk of discontinuous canals (Ndis) for MB, DB, and P roots increased with age (P<0.05), with an odds ratio of 1.61, 1.48, and 1.60 respectively.Conclusions The new indices developed in the study based on CBCT successfully demonstrate age-related changes in the root canals of primary molars.

Canal Morphology

This study aimed to investigate variations in the root canal morphology of maxillary second premolar (MSP) teeth using microcomputed tomography (micro-CT). Sixty (N = 60) human extracted MSPs were collected and prepared for micro-CT scanning. The duration for scanning a single sample ranged between 30 and 40 min and a three-dimensional (3-D) image was obtained for all the MSPs. The images were evaluated by a single observer who recorded the canal morphology type, number of roots, canal orifices, apical foramina(s), apical delta(s), and accessory canals. The root canal configuration was categorized in agreement with Vertucci’s classification, and any configuration not in agreement with Vertucci’s classification was reported as an “additional canal configuration”. Descriptive statistics (such as mean percentages) were calculated using SPSS software. The most common types agreeing with Vertucci’s classification (in order of highest to lowest incidence) were types I, III, V, VII, II, and VI. The teeth also exhibited four additional configurations that were different from Vertucci’s classification: types 2-3, 1-2-3, 2-1-2-1, and 1-2-1-3. A single root was found in 96.7% and the majority of the samples demonstrated two canals (73.3%). Further, 80% of the teeth showed one canal orifice. The number of apical foramina’s in the teeth was variable, with 56.7% having solitary apical foramen. The accessory canal was found in 33.3%, and apical delta was found in only 20% of the samples. Variable morphology of the MSPs was detected in our study. The canal configuration most prevalent was type 1; however, the results also revealed some additional canal types.
