The objective of the present study was to evaluate and compare the dentin removal capacity of Endogal Kids and Reciproc Blue NiTi alloy endodontic reciprocating systems for root canal treatments in primary second molar teeth via a micro-computed tomography (micro-CT) scan. Materials and Methods: Sixty root canal systems in fifteen primary second molar teeth were chosen and classified into one of the following study groups: A: EK3 Endogal Kids (n = 30) (EDG) and B. R25 Reciproc Blue (n = 30) (RB). Preoperative and postoperative micro-CT scans were uploaded into image processing software to analyze the changes in the volume of root canal dentin using a mathematical algorithm that enabled progressive differentiation between neighboring pixels after defining and segmenting the root canal systems in both micro-CT scans. Volumetric variations in the root canal system and the root canal third were calculated using a t-test for independent samples or a nonparametric Mann–Whitney–Wilcoxon test. Results: Statistically significant differences (p = 0.0066) in dentin removal capacity were found between the EDG (2.89 ± 1.26 mm3) and RB (1.22 ± 0.58 mm3) study groups for the coronal root canal third; however, no statistically significant differences were found for the middle (p = 0.4864) and apical (p = 0.6276) root canal thirds. Conclusions: Endogal and Reciproc Blue NiTi endodontic reciprocating systems showed similar capacity for the removal of root canal dentin, except for the coronal root canal third, in which the Reciproc Blue NiTi endodontic reciprocating system preserved more root canal dentin tissue.

It is of interest to compile available information on the root canal morphology of primary maxillary molars from known literature. The literature resources used to collect data include Medline/PubMed, The Cochrane Central Register of Clinical Trials, SIGLE and Science Direct. Data consists of type of population, number of teeth per study, number of root canals, canal length and type of root canal configuration. We used data from a total of 13 studies (951 primary maxillary molars). Maxillary molars (1st and 2nd) are dominant for two roots variant. The first molar the mean root length ranges from 7.9mm – 8.1mm. The second molar ranges from 7.2mm-8.5mm. Type I (explain in a phrase) canal morphology is the common variant in both the molars. Data shows that Root Canal morphology shows variations with the diagnostic aid (example micro CT) used and in different ethnic populations.

ABSTRACT Objective: The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classified according to the method of Vertucci. The data were analyzed by Pearson's Chi-square test. Results: The majority of mandibular molars were two rooted with three canals; however, three roots were identified in 0.05% of the first molars and 0.01% of the second molars, and 100% of the additional root canals were of type I configuration. Mesial roots had more complex canal systems with more than one canal, whereas most distal roots had a type I configuration. Conclusions: Within the limitations of this study, it can be concluded that CBCT scanning provides supplemental information about the root canal configurations of mandibular molars in a Turkish population. This study may help clinicians in the root canal treatment of mandibular molars.

The Difference

Purpose. Supernumerary roots in permanent mandibular molar teeth make endodontic treatment more complicated. The aim of this study was to determine the prevalence of Radix Entomolaris (RE) in permanent mandibular first and second molars in the population of Kerman, in the southeast of Iran. Materials and Methods. From a collection of 500 mandibular first and second molar teeth extracted over 2015-2016 at dental clinics in Kerman, teeth were scored for an additional distolingual root, and the average root length and root morphology of this extra root were determined using the De Moor classification scheme. Results. In this population, RE occurred in 6% of mandibular first molars (4% with a straight apex (Type I) and 2% with buccal apical curvature (Type III)). In all cases, RE was the shortest root, with an average root length of 18.37 mm. RE occurred in only 0.8% of mandibular second molars, with an average root length of 18.0 mm. All mandibular second molars with RE were of Type III. Fisher’s exact test showed that the difference in frequency between first and second molars was statistically significant (two-sided P=0.002). Conclusion. Radix Entomolaris occurs more frequently in mandibular first molars than in mandibular second molars in this sample of 500 mandibular molars. The reported rate of 6% in first molars is expected to be higher than reported rates in European or Caucasian populations where the prevalence is typically less than 2%.

OBJECTIVE: The aim of the study is to assess the variations in the root canal configuration of maxillary second permanent molars in the Pakistani subpopulation by using different clinical aids in vivo. METHODOLOGY: The Cross-sectional analytical study was conducted from April to October 2018 at the College of Dentistry, Riphah International University, Pakistan. The root canal configurations of Maxillary second molars were evaluated in 95 adult patients that presented to the Operative Department, after obtaining consent. After access cavity preparation the orifices were identified and cross checked using 2.5x magnification and different clinical tests. Data analysis was done by utilizing SPSS version 23. RESULTS: Out of the 95 teeth 6(6.3%) teeth had a single canal, 7(7.4%) teeth had two canals, 58(61.1%) teeth had three canals and 24(25.3%) teeth had four canals. Age-wise analysis of the frequency of different canals showed that prevalence of molars with three canals was significantly higher in the subjects with age between 41 and 50 years. Conclusion: Overall, the study noted four morphological variations in the root canal configuration of Maxillary second molar teeth in Pakistani subpopulation. Hence, while executing the endodontic treatment in the maxillary second molars a thorough assessment of the root canal system should be carried out. The results of the study can guide Pakistani dentists. KEYWORDS: Permanent Maxillary second molar, Dental Morphology, Endodontics, Pakistan

Introduction: It is important for a dental practitioner to have a clear understandingof the root canal morphology and its variations to perform successful root canal treatment.The inability to identify and adequately treat all canals of root canal system may contribute tothe failure of root canal treatment. Objectives: Clinically determine the frequency or numbersof root canals per tooth in the maxillary second molar teeth in the local population. Setting:Department of Operative Dentistry in Punjab Dental Hospital / de`Montmorency College ofDentistry, Lahore. Study Design: Randomized Control Trial. Study Period: 25th May 2013 to24th November 2013 (6 months). Results: This was a Cross sectional survey of 80 patients withsymptomatic irreversible pulpitis in maxillary second molar teeth in patients undergoing rootcanal treatment. The results showed that five (6.25%) patients had single root canal, seventeen(21.25%) patients had 2 root canals, forty (50%) patients had 3 root canals, seventeen (21.25%)patients had 4 root canals and one (1.25 %) patient had 5 root canals per tooth. In patientwith five canals, single root canal was present in distobuccal and palatal root each while threeroot canals were present in mesiobuccal root as MB-1, MB-2 and MB-3 canal. Conclusion:Local population have a lot of variations in root canal anatomy in second molar. So preclinicalknowledge can increase the success rate of root canal treatment.

ABSTRACT Objective: The objective of this study was to evaluate the mesiobuccal (MB) root canal(s) anatomy of the maxillary first and second molar teeth in an Iranian population. Materials and Methods: Cone beam computed tomography images of 280 teeth (145 maxillary first molars and 135 maxillary second molars) were analyzed to determine the number and types of the MB root canals. Chi-square test was used to examine the relationship between the number of MB canals and sex and Mann–Whitney analysis was used to define the relationship between the number of canals and the buccopalatal dimension of the MB roots. The level of interobservers' agreement was assessed with Kappa test. Results: Nearly 44.8% of the first molar and 18.5% of the second molar teeth had an additional MB canal (MB2). Types I and III of root canals had the highest frequencies. There was no significant relationship between the number of MB root canals of maxillary first and second molars and sex (P = 0.829). The relationship between the buccopalatal dimension of the MB roots and the number of root canals was shown to be statistically significant (P = 0.001). Conclusion: Presence of MB2 had a relatively high frequency, especially in the maxillary first molars. The mean buccopalatal dimension of the MB roots showed to be interrelated with the number of root canals.

ABSTRACT Objective: The apical constriction (AC) and the apical foramen (AF) are the principal reference points used to determine the apical limit for instrumentation and root canal filling. AC varies in different races, and the aim of the current study was to measure and compare the distances from AC to AF and the anatomical apex (AA) in incisor and molar teeth in the Iranian population. Materials and Methods: Forty-five roots of incisor teeth and 45 roots of molar teeth were selected randomly in Isfahan Province, Iran. If the foramen was located toward the mesial or distal side of the apex, the cut was made mesiodistally, and if it was toward the buccal or lingual side, the section was made accordingly. Roots were examined under a microscope at ×25 magnification. The distances from AC to AF and AA were then estimated using a Motic camera. Descriptive statistics were used. The independent t-test was also used to compare distances in incisors and molars, and P = 0.05 was deemed to indicate statistical significance. Results: The mean distances between AC and AF were 0.847 ± 0.33 mm in incisors and 0.709 ± 0.27 mm in molars. The mean distances between AC and AA were 1.23 ± 0.39 mm in incisors and 1.01 ± 0.38 mm in molars. In an independent t-test, the distances between AC and AF differed significantly in incisors and molars (P = 0.035), but the distances between AC and AA did not (P = 0.172). Conclusion: The end points for root canal therapy should be 0.85 mm in incisors and 0.70 mm in molars.

Irreversible Pulpitis

The root canal anatomy of mandibular second molar teeth is known to be highly variable. Whilst the most frequently seen configuration is two mesial canals and one distal canal, other variations such as four canals, two canals, and C-shaped canal system do also exist. This case report describes the diagnosis and management of unusual root canal configuration of a mandibular second molar, with one canal in a single conical root, using the contemporary advancements in endodontics. Following clinical and radiographic examinations of the case, a diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis of tooth #47 was established, and root canal treatment followed by composite buildup and crown were planned. Clinicians should be aware of the different anatomic variants each tooth may exhibit. Furthermore, clinicians need to possess the proper knowledge and skills that allow them to utilize the diagnostic and therapeutic tools available at their disposal in order to optimize the quality of care provided to their patients.
