“…In this study the mean working length of the distal root was longer than the mesial roots. The distal root showed the longest measurement (11.99 mm) followed by mesio lingual root (10.8 mm) and mesio buccal root (10.73 mm), which was in accordance with Reddy, N. Venugopal, et al 32 . where distal root showed maximum working length with a mean of 8.95 mm, whereas mesio buccal root showed minimum length with a mean of 7.85 mm, but in contrast to the findings of Zoremchhingi et al 33 .…”

In the endodontic glossary the working length is defined as the distance from a coronal reference point to the point at which canal preparation and obturation should terminate. Pulpectomy is a process of complete removal of the necrotic pulp from the root canals of primary teeth and filling them with an inert resolvable material so as to maintain the tooth in the dental arch. A University based study was conducted on mandibular primary first molar. Various pathologies such as pain, swelling, abscess and resorption were considered. Data collection was done by reviewing the patient records and analysing the data of 501 patients from June 2019 to March 2020, then excel tabulation, Statistical analysis was done using SPSS and Pearson chi-square test was performed. The total number of patients seen were 501, age ranged from 2 to 6 years. Out of the total population 42.91% (215) were female and 57.09% (286) were males. The mean length of mesio buccal canal was 10.76 mm, mesio distal canal -10.88 mm, and the distal canal was 11.2 mm in the mandibular first primary molar. Pulpal pathology with mean working length of the root canals were as follows, In pain the mesio buccal root had 10.76 mm, mesio lingual root had 10.81 mm and the distal root had 12.01 mm. Abscess the mesio buccal root had 10.75 mm, mesio lingual root 10.79 mm and the distal root 12.03 mm. Swelling the mesio buccal root had 10.75 mm, mesio lingual root had 10.80 mm, and the distal root had12 mm, Resorption mesio buccal root had 10.77 mm, mesio lingual root had 10.78 mm, and the distal root had 11.8 mm. In regard to various pathogens such as pain,swelling, abscess and resorption the working length was determined as 10.76 mm for mesio buccal root, 10.88 mm for mesio lingual root and 11.2 mm for distal root of the mandibular first primary molar.

“…Root canal treatment or partial pulpectomy has become part of the routine treatments of primary teeth. To ensure normal physiological resorptive process and exfoliation, or if tooth retention is required for some time, and to optimize these procedures, it is necessary to realize the anatomy of these root canal miniatures, with all associated anomalies and fine communications, just like in permanent teeth (59)(60)(61)(62)(63). Root canal treatment in primary teeth has challenged with many factors, signing first one which is aberrance from normal morphology specially in the posteriors, as a result of dentin islands formed continuously, in addition to physiologic resorption that may alter the working length, moreover anterior primary teeth normally show additional canals specially in upper canines.…”

Background: Morphology of the root canal system is divergent and unpredictable, and rather linked to clinical complications, which directly affect the treatment outcome. This objective necessitates continuous informative update of the effective clinical and laboratory methods for identifying this anatomy, and classification systems suitable for communication and interpretation in different situations. Data: Only electronic published papers were searched within this review. Sources: “PubMed” website was the only source used to search for data by using the following keywords "root", "canal", "morphology", "classification". Study selection: 153 most relevant papers to the topic were selected, especially the original articles and review papers, from 1970 till the 28th of July 2021. Conclusions: This review divided the root canal analysis methods into two approaches; clinical and in vitro techniques. The latter has shown more precise non-subjective readings, on the other hand; the clinical methods provide direct chair side diagnosis for the clinical cases. The classification systems reviewed in the present study, started with the oldest trials that simply presented the root canal systems, according to the degree of angulation, or by coded Latin numbers or English letters. Then, the most recent systems were also presented that were persisted with continuous editions up to date. These new systems could briefly describe the root and root canal’s internal and external details in a small formulation, without confusion and in an easily communicated manner, highly recommended specially for students, teachers, and researchers

“…Caries is the most common etiological factor that leads to pulpal involvement, which necessitates treatment to preserve the integrity of dental tissues. 1 Primary teeth have a thinner layer of mineralized tissue between the external and interior surfaces of teeth than permanent teeth, allowing bacteria to readily penetrate the pulp. 2 …”

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.
