“…and other researchers. [ 6 45 49 50 57 58 ] as well as the combination of alternating image reformatting techniques in micro-computed tomography involving two-dimensional minimum intensity projection and 3-dimensional volume rendering reconstruction images have been discussed;[ 7 ] the time tested clearing technique was used in this study. There is no doubt that the dye penetration and clearing technique helps in a better visualization and understanding of the root canal anatomy adding more value in endodontic teaching.…”

Objective:The objective was to study the root canal morphology of South Asian Indian Maxillary molars using a tooth clearing technique.Materials and Methods:Hundred teeth each comprising of first, second, and third molars collected from different dental schools and clinics in India were subjected to standard dye penetration, decalcification and clearing procedure before being studied.Results:The first molar mesiobuccal roots exhibited 69% Type I, 24% Type II, 4% Type IV, 2% Type V, and 1% exhibited a Vertuccis Type VIII canal anatomy. In the group with three separate roots the second molar mesiobuccal roots in exhibited 80.6% Type I, 15.3% Type II, 2.7% Type IV, and 1.4% Type V canal anatomy while the third molars mesiobuccal roots exhibited 57.4% Type I, 32% Type II, 2.1% Type III, 8.5% Type IV, 1% had a Type V canal anatomy in the similar group.Conclusion:A varied root canal anatomy was seen in the mesiobuccal root canal of the maxillary molars.

“…Various techniques have been employed to evaluate canal morphology such as conventional[ 20 ] and digital radiographic techniques,[ 21 ] using cross-sections,[ 22 ] cone-beam computed tomography (CT),[ 23 ] and peripheral quantitative computed tomographic imaging. [ 24 ] More recently, micro-CT has been utilized in canal morphology studies.…”

Objective:The purpose of this study was to determine the root canal anatomy of mandibular first premolar teeth in an Emirati subpopulation using a decalcification and clearing method.Materials and Methods:One hundred permanent mandibular first premolar teeth extracted for orthodontic purposes from an Emirati subpopulation from the United Arab Emirates were used for this study. They were subjected to decalcification and clearing. The tooth length, the canal orifice shape, mesial invagination, canal pattern, the location of apex, presence of lateral canals, and intercanal communications were determined.Results:The most common canal pattern was the Vertucci Type I (65%) followed by Type V (14%) and Type IV (13%). The most common type of canal orifice seen was the oval shape (36%) followed by the round shape (25%). Mesial invaginations were seen in 44% of the teeth. The mean tooth length was 19.9 mm, and apical deltas were seen in 24% of teeth.Conclusion:The Vertucci Type I canal pattern was the most prevalent in the mandibular first premolars while the occurrence of multiple canals was noted in 35% of this population.

“…In addition, the use of more than one observer to assess technique reproducibility lowers the chances of successfully obtaining measurements of desirable quality (26). When radiographic images are analyzed by several observers, a great discrepancy between the obtained results is observed; however, when the same observer (intrarater) performs the comparisons individually using different techniques and images, the accuracy of the obtained results increases (27,28). The present study used a single observer similarly to the characteristics described earlier, taking into account that the analysis of DSR images requires training and experience in order to increase result reliability (29).…”
