“… 2 Root canal system in primary teeth seems to be more complicated than permanent teeth. 3 , 4 This complexity is mostly attributed to the presence of ramifications 5 and microcanals, 6 in their root canal system. This can make the root canal treatment of primary teeth a more challenging procedure due to the fact that mechanical instrumentation alone cannot eliminate bacteria from these microcanals.…”

Background. This in vitro study aimed to compare the antibacterial effect of different concentrations of sodium hypochlorite on elimination of Enterococcus faecalis from root canal systems of primary teeth with or without a passive sonic irrigation system (EndoActivator). Methods. The root canals of 120 extracted single-rooted primary incisors were prepared using the crown-down technique. The teeth were autoclaved and inoculated with E. faecalis. The infected samples were then randomly divided into 6 experimental groups of 15 and positive and negative control groups as follows: group 1: 0.5% sodium hypochlorite solution; group 2: 2.5% sodium hypochlorite solution; group 3: 5% sodium hypochlorite solution; group 4: 0.5% sodium hypochlorite solution + sonic activation; group 5: 2.5% sodium hypochlorite solution + sonic activation; and group 6: 5% sodium hypochlorite solution + sonic activation. Microbiological samples were collected before and after disinfection procedures and the colony-forming units were counted. Statistical analyses were performed using the two-way ANOVA and post hoc Duncan's tests in cases of significant difference. Results. There were no significant differences between the groups in any of the variables (concentration of antiseptic or use of sonic irrigation system). Conclusion. Use of passive sonic irrigation systems in endodontic treatment of single-rooted primary teeth is of no benefit compared to regular needle irrigation. The results of this study also recommends use of lower concentrations of sodium hypochlorite solution (0.5%) for irrigation of the root canal system rather than higher concentrations given approximately equal efficacy.

“…Primary incisors and canines have been reported to have less complex root canal morphologies compared to primary molars. 19,32 Root canal number of both mandibular and maxillary molars vary between 2-5 8,10,20,32,34 , resulting with greater morphologic variations in their root canal systems, which has been reported to be most frequent especially in mandibular primary molars. 13,20,34 Regarding this, the present study was carried out on mandibular primary first and second molars.…”

Objectives: Frequency of typical and non-typical root and canal morphology of primary teeth, which in clinical practice cannot be detected using 2D radiographic images, should be known by clinicians to decrease failures arising from complexity of root canal morphologies. The aim of this in vitro study was to evaluate morphologic variations in mandibular primary molars' root canal systems. Materials and Methods:Primary mandibular 1 st (n=17) and 2 nd (n=33) molars were scanned using micro-CT. 3D root models were obtained and root canal morphologies were evaluated according to a modified Vertucci classification. Type 1 and Type 4 canal morphologies were evaluated as 'normal' and all other types and 'non-typical' canal morphology were evaluated as 'abnormal' root canal morphology.Results: Most common root canal morphology among mandibular primary 1 st molars were Vertucci Type 4 morphology for both mesial and distal roots (47% and 41.2% respectively), and non-typical morphology for both the mesial and distal roots (45.7% and 21.2% respectively) of mandibular primary 2 nd molars. Conclusions:Wide range of morphologic variations and frequency of non-typical morphology could be seen especially among mandibular primary 2 nd molars and use of disinfectant irrigants and root canal fillings with high antibacterial efficacies are important in order to decrease failures arising from these inaccessible areas.

“…Further-more, each mesial root in a primary mandibular 2nd molar had 2 canals, which is consistent with the studies conducted by Joseph et al [2], Bagherian et al [5], Aminabadi et al [8] and Gaurav et al . [3]. From this result, clinicians should expect a high probability of locating two canals in mesial roots of primary mandibular molars.…”

The purpose of this study is to identify the most common canal type in primary molars and the correlation between their roots and canals. A comprehensive understanding of root canal morphology will lead to more successful root canal treatment. Computed Tomography (CT) images from 114 children (81 boys, 33 girls) aged 3-7 years were obtained. The locations and numbers of roots and canals were evaluated, and the relationship between root and canal parameters was determined. The most commonly observed canal morphology in primary maxillary molars were mesio-buccal, disto-buccal and palatal canal. Primary mandibular molars most frequently contain mesio-buccal, mesio-lingual, disto-buccal and distolingual canal. All the roots of the primary maxillary molars except for the mesio-buccal root, each had 1 canal while there were 2 canals observed in each root of primary mandibular molars. Without exception, all mesial roots in primary mandibular 2nd molars had 2 canals. In case when either the palatal root in a primary maxillary molar or the distal root in a primary mandibular molar was separated into 2 roots, each root seemed to have its own canal. Even though the disto-buccal and palatal roots were fused into 1 root in primary maxillary molars, this fused root had tendency to have 2 separate canals. Primary mandibular molars showed similar canal morphologies between left and right molars in the same patient, while the primary maxillary molars did not.
