“…13 However, Godze Oscan has found four classes (class I–IV) in the root canal of primary molars. 14 , 15 But in our study, apart from the four classes (class I–IV), we found one more variant which has not been much reported in the literature. As a result, this research suggests that CBCT is useful in evaluating the root and canal system, but it should not be utilized routinely.…”

Introduction Visualizing the pulp cavity requires adequate knowledge of the size, morphology, and variation of the root canals of primary teeth. The morphology of the root canals in deciduous teeth causes difficulties during endodontic treatment. There have not been many studies on root canal variations in primary teeth in the Indian population. Aim and objective To assess the variation in the root and canal morphology of primary maxillary second molars using cone-beam computed tomography (CBCT) in the pediatric Indian population. Materials and methods The institutional database and private diagnostic centers were used to gather CBCT images of 25 children (50 images) between the age-group of 5 years and 9 years. The CBCT images were rebuilt using Scanora software, and the data were assessed and analyzed using the SPSS version for Windows. Results Out of 50 primary maxillary second molars, the majority of the second molars had three roots and three canals (Variant I) which account for 66% of teeth. Variant II had three roots and three canals with distobuccal and palatal roots fused in 14% of cases whereas 18% of cases showed three roots and four canals in which mesiobuccal root had two canals (Variant III). The remaining 2% of cases showed four roots with four canals (Variant IV) which were statistically significant. Conclusion We concluded that within the constraints of our study, there was a difference in the root canal configuration of primary maxillary second molars in the investigated group of the Indian population.

“…Nevertheless, for the analysis of biological effects, this methodological feature is irrelevant to determining the anatomical dimensions of a primary tooth; moreover, radiation in paediatric patients should be restricted to extremely necessary cases. However, the “in vitro” methodology is more rigorous in anatomical studies, such as this and other studies [ 1 , 2 , 3 , 4 , 5 , 6 , 9 , 11 , 12 , 13 , 16 , 27 , 34 , 35 , 36 ], by allowing the fixation of the teeth during handling.…”

“…This fact becomes more important in a primary tooth, as it presents a lower thickness of enamel and dentine tissues [ 4 ]. Making a correct access cavity in pulp therapy allows for the removal of all tissues housed in the chamber and correct visualisation of both the pulp floor and the entrance to the root canals, thus improving the long-term prognosis [ 5 , 6 , 7 , 8 , 9 ]. Furthermore, knowledge of the morphological characteristics of the chamber pulp floor prevents possible iatrogenesis during the technique.…”

“…A three-dimensional reconstruction is possible, reflecting greater accuracy of the most relevant anatomical features of the pulp chamber, thus being able to explain the successes and failures of different restorative or pulp therapies. However, there is a lack of research on this topic because most studies focused on one racial group [ 1 , 2 , 5 , 6 , 13 ]. For this reason, as of today, despite the studies, knowledge of the deciduous teeth anatomy is still insufficient due to the great anatomical variability it presents.…”

The anatomical variability of primary molars promotes research to improve clinical restorative activity, forensic identification, and industrial development. The objective was to study the morphology of the pulp chamber and its three-dimensional relationship with the external morphology of the tooth. A total of 151 deciduous molars were collected and subjected to three-dimensional imaging analysis in order to determine dental crown (CV) and pulp chamber (PV) volumes, their ratio (VR), pulp chamber roof (PCR) and pulp chamber floor (PCF) area, the furcation length (FD), and morphological peculiarities. The data were compared using the Kruskal–Wallis test in SPSS 26 software. The statistical analysis determined statistically significant differences between the four groups of molars for all variables. Great anatomical variability was observed, especially in the maxillary first molar, the volumes were higher in the maxillary second molar and the highest risk of furcal perforation was seen in the mandibular first molar. Additionally, mandibular second molars with six pulp horns, and some different density images compatible with accessory canals and pulp stones were found. Based on the findings of this investigation, we confirm the great anatomical variability that exists between the maxillary and mandibular molars.

“…The close approximation of ZOE material in the mesio-distal confines of the pulpal cavity must have blinded its inadequate condensation in the opposite bucco-lingual margins. Baccouche et al studied the topography of primary molars and observed that the greatest dimension of the pulp chamber was significantly higher in the buccolingual axis than mesiodistal particularly in primary maxillary molars ( Baccouche et al, 2013 ). This difference in the pulp chamber proportions can contribute to a greater number of teeth with poor ZOE condensation as seen on antero-posterior xrays in the current study.…”

Purpose To compare three condensation techniques of zinc oxide eugenol (ZOE) as a pulpal dressing material during pulpotomy in extracted primary molars. Material and Methods Sixty primary first and second molars were embedded in individual wax casts and divided into three groups consisting of 20 teeth each. In group I, the ZOE base was condensed by an amalgam condenser, while a moist cotton pellet was used in group II. A combination of an amalgam condenser and a wet cotton pellet tested the condensation mentod in group III. The condensation quality of the three techniques was evaluated through two digital periapical radiographs taken in a lateral and anterior-posterior direction. Results Non-parametric Kruskal-Wallis test showed that there was no significant difference between the technique and quality of ZOE compaction. However, a significant difference was observed on condensation assessment for combined three groups on lateral radiographs vs the appearance on antero-posterior radiographs with the p-value set at < 0.05. Conclusion Voids appeared with all three techniques. A combination of an amalgam condenser and the wet cotton wool pellet was the least effective method of condensation. Lateral radiographs revealed much fewer spaces between the ZOE and pulpal floor in comparison to antero-posterior images.

Abstract: Mesiodistal dimension of the pulp cavity is not proportional to that of the dental crown. Endodontic access cavity have to be shifted to the distal and vestibular sides from the first to the second upper molar.
