“…However, only two reports have described the presence of double root canals in a single palatal root[ 26 , 27 ]. Kottoor et al [ 26 ] reported that two root canal orifices were identified in a single palatal root and that the palatal root canal had a type II morphology, while Shahi et al [ 28 ] suggested the incidence of a single palatal root of the maxillary first molars with two root canals is 0.73%, indicating a type V canal morphology. Neelakantan et al [ 29 ] revealed that the incidence of two root canals in the palatal root of maxillary first molars in the Indian population was 5.4%, of which 4% had a type IV morphology, while the remaining 1.4% had a type V morphology.…”

BACKGROUND Root canal variations frequently occur in maxillary first molars, which greatly affects the success of its treatment. The second mesiobuccal (MB) root canal is the most common root canal variation. However, only a few studies have been conducted on palatal root canal variations. Herein, we report the presence of two separate root canals in a palatal root of the maxillary first molar. CASE SUMMARY A 39-year-old woman complained of pain in the maxillary right region for 1 year, which recently worsened. Clinical examination revealed a poorly restored right maxillary first molar and caries detected at the filling marginal. Cold and heat test results indicated severe pain in the right maxillary first molar. The patient was diagnosed with irreversible pulpitis, and subsequently, root canal treatment (RCT) was performed. In total, five root canals were found in the maxillary first molar, including two separate root canals in the palatal root. RCT was successfully performed using an endodontic microscope and cone-beam computed tomography (CBCT). The CBCT image revealed a vertucci type I canal morphology in the distobuccal root, while the MB and palatal root canals were type Ⅳ. At the 1-mo follow-up, the maxillary first molar was completely asymptomatic, and the X-ray results indicated a successful RCT. Finally, the ceramic crown restoration was performed. CONCLUSION An endodontic microscope and CBCT are useful in effectively identifying and treating root canal variations.

“…18 Although maxillary molars have been reported to be associated with several morphological variations, the appearance of two palatal canals is considered a rare phenomenon. 16,17 In this report, we describe a maxillary right second molar requiring root canal treatment, with a rare morphological occurrence of two separate palatal canals in a single palatal root (Vertucci type IV canal configuration). 1 Previous studies reported bifurcated canals, double roots or variations in MB and DB roots.…”

“…1,15 Few studies and case reports reported a rare appearance of two palatal canals/roots (bifurcated canals) in maxillary molars showing a low incidence of 0.73-2%. 5,16,17 Cone beam computed tomography (CBCT) is a modern and effective method that is being widely used in dentistry. 2 In contrary to traditional radiography, CBCT can provide 3-dimensional (3D) illustration of teeth, which can aid in analyzing the internal and external tooth anatomy and provide a more precise imaging of the root and canal system.…”

Cases of unusual and complex root canal morphology could be difficult to diagnose and treat. This report describes the diagnosis and management of a rare maxillary right second molar (tooth #17) with two distinct palatal canals. The tooth was diagnosed with irreversible pulpitis and symptomatic apical periodontitis. Non-surgical root canal treatment was performed. Accurate diagnosis and comprehensive treatment of cases with unusual root canal morphology can be achieved by evaluation of periapical radiographs at different angulations, advanced magnification techniques, and the Cone Beam Computed Tomography (CBCT) scanning. Clinicians should be aware that two separate palatal canals could exist in maxillary second molar teeth.

Aim: Analysis of root canal pattern in the mesiobuccal root of maxillary first and second molars using CBCT.Methods: In this study fifty human extracted teeth with fully formed apices were selected (twenty five maxillary first molars and twenty five maxillary second molars). CBCT was used to evaluate the presence of the MB2 (mesiobuccal) root canal and the morphology of root canals in MB root (the type of root canal system).Results: CBCT examination showed that out of 25 maxillary first permanent molar teeth studied, the mesiobuccal roots with a single canal were of type I (56%) or type III (4%) configuration. Those with two canals were of type II (24%) or type IV (16%) configuration. Regarding the maxillary second permanent molars the mesiobuccal roots were with a single canal of type I (64%) configuration. Those with two canals were of type II (12%), type IV (20%) or type VI (4%) configuration. Conclusion:CBCT scans certainly show promise as a modality to facilitate the identification of root and canal configuration. The information gained about the tooth anatomy and canal morphology before treatment could potentially facilitate root canal therapy.
