Effective endodontic treatment relies on a strong understanding of root canal anatomy, specific evaluation of the pulp chamber floor, critical interpretation of radiograph, and chemo-mechanical planning accompanied by three-dimensional obturation of root canal system. The risk of extra root /canal should be considered even in teeth with a small incidence of irregular root canal morphology. Mandibular premolars have acquired the distinction for having aberrant anatomy. This article reports and discusses the successful endodontic management of mandibular first premolar with one canal bifurcating into two canals.

AIM: The purpose of this study was to describe the external and internal anatomy of the mandibular premolars. MATERIAL AND METHODS: 100 extracted human permanent mandibular first and second premolars teeth were collected. The length of the tooth from the cusp tip to root apex was measured with the help of Vernier calliper. In case of curved roots, ligature wire was adapted to the root and then straightened and measured. Each tooth was examined for the number of roots, curvature of root, presence of root canal invagination. India ink was injected into the pulp chamber through the access opening with a no.27 gauge needle mounted on a disposable syringe. The ink was then drawn through the root canal system by applying negative pressure to the apical end of tooth with the use of central suction system. RESULTS: The average (mean) length of mandibular first premolar was 22.25 mm. Average (mean) length of mandibular second premolar was 21.90 mm. Mandibular first premolar had a ribbon shaped root canal orifice in 35% of teeth. Mandibular second premolar had a ribbon shaped of root canal orifice in 44% teeth. Mesial invagination of the root was found in 18% of first and 8% second mandibular premolar teeth. 78% had a Type I canal pattern with Type II, Type IV, Type V, Type VI and Type VII canals being identified in 1%, 2%, 13%, 2% and 1% of the teeth respectively. CONCLUSIONS: Complex root canal anatomy frequently found with mandibular premolars among which more common with mandibular first premolars in Indian population.

The success of endodontic therapy is attributed to complete arbitration of the bound entities concealed within the complexity and absolute disinfection of the root canal system, thus, deeming it mandatory to effectively negotiate and overcome the challenges posed by obstruction, either iatrogenic or anatomic. To achieve this, considerable depth of knowledge and expertise with reference to variations in root canal morphology and clinical mishap management is substantially as important as developing fine observation skills in conjunction with an appropriate armamentarium and a keen sense of determination, thereby enhancing one’s clinical acumen by several folds. In the present case, following rubber dam isolation, the temporary restoration was removed, and the remaining carious dentin was excavated. Endodontic access cavity was refined and explored with a DG-16 probe, following which three separate canal orifices were identified in the pulp chamber floor (mesiobuccal, mesiolingual, and distal). On further observation under a surgical operating microscope and continuous exploration with the DG-16 probe, a fourth canal was found in the mesial aspect of the tooth (middle mesial). With instrumentation, it was confirmed that a fractured object was indeed present at the apical third of the mesiolingual root of tooth 38. Bypassing of the fractured fragment was initiated with a size 10 SS K-file coupled with copious irrigation with 3% sodium hypochlorite. In the present case report, four distinct canals comprising 3 mesial and 1 distal canal were recognized, and the fractured instrument in one of the canals was bypassed successfully.

Endodontic treatment of mandibular molars is challenging because of variable root canal morphology. The nonsurgical endodontic management of a mandibular first molar presenting an independent middle mesial canal is reported. After coronal access, additional clinical inspection of the mesial canals’ orifices and their interconnecting groove using an endodontic explorer and 4.5× loupes enabled the identification of the middle mesial canal orifice. All root canals were chemomechanically prepared and filled. The tooth was asymptomatic and functional after 4 years of followup. Cone beam computed tomography (CBCT) images revealed normal periapical status and three-dimensional (3D) anatomical aspects of the root canal system.

Introduction: There are certain common as well as atypical characteristics in the root canal anatomy of each tooth. Simultaneous understanding of both can be the key to successful endodontics. Various methods have been used till date for visualisation of root canal morphology with variable success rates like magnification, radiography, CBCT, digital imaging and clearing. Clearing technique provides a three-dimensional view of the root canal anatomy from outsidewhile maintaining the original form and relationship of canals as minimal instrumentation is required in the procedure. It is a simple and inexpensive technique which involves decalcification of tooth structure, dehydration in alcohol and clearing by immersing in clearing agents. Aim: This study aimed to evaluate the efficacy of two decalcifying agents (nitric acid and trichloroacetic acid) and two clearing agents (methyl salicylate and eugenol) in the preparation of transparent tooth model for viewing the root canal system. Materials and Methods: The in-vitro research study from August 2, 2019 to August 27, 2019 included 40 freshly extracted teeth (18 maxillary and 22 mandibular) which were randomly divided in two groups (n=20); group A (decalcification done in 5% nitric acid) and group B (decalcification done in 10% trichloroacetic acid). Then, the teeth were dehydrated in isopropyl alcohol. Each group was subdivided in two subgroups depending on the clearing agent used (methyl salicylate or eugenol). Afterwards they were graded for transparency and haziness criteria, and data analysis was done using chi-square test, value of significance at p<0.05. Results: The results showed that nitric acid took lesser time for decalcification than trichloroacetic acid. The subgroup 1 (NA/MS) showed better transparency level in 90% of the samples when compared with other subgroups; however the results were not significant with p-value 0.121. Haziness was present in all samples. The subgroup 4 (TCA/E) showed 100% haziness which was statistically significant among all the subgroups with p-value 0.002. Methyl salicylate showed better transparency, less haziness and good root canal morphology when compared with eugenol. Conclusion: Nitric acid when used in combination with methyl salicylate prepared the best transparent tooth model. Trichloroacetic acid showed average transparency and haziness was present in almost all the samples irrespective of the clearing agents used.

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.

ABSTRACT Tooth resorption is a condition associated with either a physiologic or a pathologic process resulting in a loss of dentin, cementum, and/or bone. Inflammatory process is initiated when the predentin or precemental layer of the tooth is damaged. Resorption can either be external or internal in form. In order to control the tooth resorption, it is necessary to treat the root canal by removing all the pulp tissue. Due to varied root canal morphology, root canal treatment poses a challenge for the clinician. In such cases a combination of conventional lateral compaction and thermoplasticized gutta percha can enable the three-dimensional obturation of the canal space. This case report describes a nonsurgical mode of management of a tooth having internal and external (surface) resorption. How to cite this article Anilkumar A, Nair KR, Nazar F, Rajendran R.

Canal Morphology

The complex root canal system of maxillary second premolars shows variations among different populations. The aim of this study was to evaluate the root canal morphology of second maxillary premolars in the romanian population. The number of roots, root canals and the root canal configuration were investigated using radiographs in both buccal-oral and mesio-distal incidence. They were categorized using Weine’s classifi cation. Among the 480 teeth, 90.83% had one root and 66.67% one root canal. The frequency of secondary maxillary premolars with two root canals (33.12%) shouldn’t be underestimated. Knowing the variations of the internal root canal morphology of maxillary second premolars in a certain population can lead the clinician to a better approach of the endodontic treatment.
