“…[ 2 ] Mandibular first molar typically has two roots with a round or elliptical canal in the distal root and two canals in the mesial root, but infrequently, it has three with two or three canals in the mesial root and one, two, or three canals in the distal root. Though many variations have also been reported with this tooth, which includes the presence of single root,[ 3 ] four roots,[ 4 ] taurodontism,[ 5 ] radix entomolaris,[ 6 ] and radix paramolaris.

A BSTRACT Background: Root canal (RC) treatment is most common and effective method for treatment of diseases related to periapical area and pulp of teeth. With the increase in age, the formation of secondary dentin, calcification of canals, and reduction of medullary cavity volume, it becomes increasingly difficult to accomplish a perfect RC treatment, hence the understanding of RC variation and changes in variation with increasing age improves the success rates. Aim: The aim of this study was to study the RC variation in the age-group of 10–14 years and to find if the gradual increase in age plays a role in increasing the complexity of RC variation. Materials and Methods: This study was carried out in Government Medical College, Patna, Bihar, India, from January 2018 to April 2019. Subjects within the age range of 10–14 years were selected conferring to predetermined inclusion and exclusion criteria. The subjects were divided into the groups according to age—Group I: 10–11 years, Group II: 11–12 years, Group III: 12–13 years, and Group IV: 13–14 years. The subjects were further divided into Group A and B according to sex to study if there is any significant difference in RC variation. Three intraoral periapical (IOPA) radiography with radiovisiography (RVG) of each subject were taken from three different predetermined angles and these IOPAs were then analyzed by three independent observers and the most agreed on value was included. The IOPAs were analyzed for the number of roots, the number of canals in each root and the variation of each RC were classified according to Vertucci’s Classification. Results: The most common T of RC variation in mesial root of mandibular first molar was T IV succeeded by T II and T I. For distal canal of mandibular first molar, the most common variation was T I, followed by T II and T III. In our study we found that 98.88% of mandibular molars were having two roots. No significant difference was found in the variation of canal according to age or sex in our study. Conclusion: Hence, we conclude that no significant difference is seen in RC variation according to sex and age. As the groups we included in our study were not wide apart enough in age, a further long-term study is needed to ascertain if the complexity of RC increases with age.

“…The mandibular first molar is considered to be the most common tooth to involve in the endodontic procedure because it is earliest permanent tooth to erupt. [ 3 ] Because of the greater number of endodontic treatments involving this tooth, the clinician may be confronted in many cases of mandibular first molars with variation in root (single root,[ 4 ] four roots,[ 5 ] taurodontism,[ 6 ] radix entomolaris,[ 7 ] Radix paramolaris[ 8 ]) and internal anatomy (middle mesial,[ 9 10 11 12 13 14 ] middle distal,[ 5 9 13 14 15 16 ] and C-shape[ 17 18 ]). However, presence of four canals in the mesial root is extremely rare.…”

Internal anatomy of pulp is complex. The first mandibular molars typically have two roots, one mesial with two root canals and another distal root, which contains one or two canals. A 20-year-old female patient reported with intermittent pain and incomplete root canal treatment in left lower back region since 1-week. Refined access cavity revealed initially two canals in mesial and two canals in the distal root. With operating microscope and cone beam computerized tomography, two additional canals (L-mesio-buccal and B-mesio-lingual) were identified in mesial root. One-year follow-up showed patient was asymptomatic and complete healing of periapical radiolucency.
