Abstract A progressive bacteria invasion on tooth tissues leads to pulp inflammation, microabscesses of the pulp, destruction and in consequence inflammation of periapical tissues. Therefore the aim of endodontic treatment is three dimensional debridement of a root canal from the vent in pulp chamber to the physiological narrowing. Therefore the aim of the study is analysis of root canal configuration, number of canals, presence of lateral canals and canal delta with the group of first permanent molars. At the same time the accuracy of the radiological examination (x-ray images) is estimated due to comprehension of X-ray images performed before teeth preparation with root canal system and after observation of transversal cuts by means of light microscopy and microtomography. This establishment is presented through the differences in conventional radiological image and clinical assessment.

Root Canal System

To report a case of endodontic treatment of a maxillary canine in which an extra canal was located and successfully treated. Endodontic therapy is essentially a micro neurologic surgical procedure involving complete debridement and three dimensional obturation of the root canal system to obtain a fluid impervious seal. The foundation of the procedure is based on the intimate knowledge and thorough understanding of the anatomy of both the pulp chamber and the root-canal system. A tooth exhibit variations in their root canal anatomy and poses a challenge in diagnosis and treatment. In the teeth particularly with additional root canals or anatomical variations, root canals are often left untreated and that would be the main reason for unfavourable outcome of the treatment. Maxillary canine are statistically more commonly single rooted, single canal but rarely may have single root with two root canals.Journal of Universal College of Medical Sciences, Vol. 5, No. 2, 2017, Page: 53-56

Introduction. Understanding the morphology of the root canal system, and especially its apical third, represents the basic precondition for the successful treatment of diseased pulp and the apical endodontium. Aim. The aim of this study was to precisely locate the main and ancillary foramina in the mesial and distal first lower molars. Method. One hundred extracted first lower molars, originating from persons of both sexes and three different age groups, were used in the study. Results. The analysis of the sampled molars? apical third was carried out using a binocular magnifier and a digital X-ray scanner (Trophy). The results showed that the main mesial and distal root foramina were located mostly on the distal surface. The ancillary mesial and distal root foramina were located at the lingual end, in most cases. Statistical analysis demonstrated the congruence of results achieved using the binocular magnifier and digital x-ray in 100% of cases if the main foramen is located on the very top of the mesial root (?2 =17.23; p<0.001), and in 92.9% of cases if the main foramen is localised on the very top of the distal root of the first lower molar (?2 =12.07; p<0.001). Conclusion. The most common localisation of the main foramina for all age categories and in both mesial and distal roots is on the distal surface of the root. The greatest number of ancillary foramina was observed in the youngest age category, while they were localised most often on the lingual side of the mesial and distal root.

Canal Morphology

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.

AbstractThis study aimed to analyze the root anatomy and root canal system morphology of mandibular first premolars in a Chilean population. 186 teeth were scanned using micro-computed tomography and reconstructed three-dimensionally. The root canal system morphology was classified using both Vertucci’s and Ahmed’s criteria. The radicular grooves were categorized using the ASUDAS system, and the presence of Tomes’ anomalous root was associated with Ahmed’s score. A single root canal was identified in 65.05% of teeth, being configuration type I according to Vertucci’s criteria and code 1MP1 according to Ahmed’s criteria. Radicular grooves were observed in 39.25% of teeth. The ASUDAS scores for radicular grooves were 60.75%, 13.98%, 12.36%, 10.22%, 2.15%, and 0.54%, from grade 0 to grade 5, respectively. The presence of Tomes’ anomalous root was identified only in teeth with multiple root canals, and it was more frequently associated with code 1MP1–2 of Ahmed’s criteria. The root canal system morphology of mandibular first premolars showed a wide range of anatomical variations in the Chilean population. Teeth with multiple root canals had a higher incidence of radicular grooves, which were closely related to more complex internal anatomy. Only teeth with multiple root canals presented Tomes’ anomalous root.

We aimed to analyze the morpho-geometric changes of the root canal system created by two rotary systems (TF Adaptive and BioRace) using micro-CT technology. Two concepts of rotary file system kinematics, continuous rotation and adaptive kinematics, were used in root canal preparation. Twenty mandibular molars (n = 20) were selected with the following criteria: the teeth have mesial roots with a single and continuous isthmus connecting the mesiobuccal and mesiolingual canals (Vertucci’s Type I configuration) and distal roots with independent canals. Teeth were scanned at a resolution of 14 μm. Canals were divided equally into two groups and then enlarged sequentially using the BioRace system and TF Adaptive system according to manufacturer protocol. Co-registered images, before and after preparation, were evaluated for morphometric measurements of canal surface area, volume, structure model index, thickness, straightening, and un-instrumented surface area. Before and after preparation, data were statistically analyzed using a paired sample t-test. After preparation, data were analyzed using an unpaired sample test. The preparation by both systems significantly changed canal surface area, volume, structure model index, and thickness in both systems. There were no significant differences between instrument types with respect to these parameters (p > 0.05). TF Adaptive was associated with less straightening (8% compared with 17% for BioRace in the mesial canal, p > 0.05). Both instrumentation systems produced canal preparations with adequate geometrical changes. BioRace straightened the mesial canals more than TF Adaptive.
