“…Extensive literature [9,45], clinical study [2,8,30,41,46,47,48,49] and case reports are presented on maxillary first molars (Table 2). Among the root canal anomalies of maxillary molars, the least frequent appears to be that of palatal root.…”

“…Extensive studies and case reports regarding the unusual anatomical variation and configuration of the root canal system in maxillary first molars have been illustrated. These include a single root canal in a single root [11,12], two root canals [13], five root canals [14,15,16,17,18], six root canals [19,20,21], seven root canals [22], eight root canals [1], Cshaped canals [23,24], fusion of two buccal roots [25], fusion of two buccal roots with two palatal roots [26], four roots including an additional palatal root [27][28][29][30][31][32][33] and also five roots [31]. There are innumerable case reports and clinical studies of maxillary first molar on varied root canal morphology.…”

The success of endodontic treatment not only lies in meticulous cleaning, perfect shaping and precise filling of canels, it also embodies vital importance on familiarity of unusual root canal patterns. This article presents a case report of a maxillary first molar that had two separate palatal roots with distinct canals and also an invitro assessment of an extracted tooth which had a a similar root canal morphology using cone beam computed tomography (CBCT). Both of them highlight the importance of knowing the anatomical variations to achieve a functional and biological favourable outcome in endodontic treatment.

“…26 Following this, many other studies and case reports have shown the difficulty in assessing the root and root canal morphology of the upper molar and its variation in root fusion from diagnostic radiographs. [26][27][28][29][30] In all these case reports and studies it is shown that root variation in the upper molar can be suspected if there is any variation from normal root morphology in the diagnostic radiograph, and this can be confirmed during access cavity preparation by identifying the extra root canal orifice or by taking additional radiographs. In accordance with these studies and case reports, many practitioners in this study were not able to detect the normal root morphology and its variation in upper molar radiographs.…”

Objectives: The aim of this study was to evaluate which radicular radiographic features general dentists want to interpret, determine which of the radicular radiographic features general dentists interpret and which ones they miss in a diagnostic radiograph and correlate how accurately general dentists are able to interpret radiographic features. Methods: 20 general dental practitioners were selected and given 2 sets of questionnaires. The first set asked them to fill out the findings they would elucidate in a diagnostic radiograph while the second set consisted of 30 randomly selected intraoral radiographs to interpret. Results: In the first set of questionnaires, more than 50% of dentists said they would interpret periapical changes, calcification, root curvature and the number of root canals. Less than 50% said they would interpret canal morphology, open apex, resorption, fracture, number of roots and lamina dura. In the second set of questionnaires, more than 90% missed grade 1 or 2 periapical changes (according to periapical index scoring), resorption and canal calcification. More than 80% of dentists missed extra roots and root curvature buccally while no dentists were able to interpret the periodontal ligament width changes, lamina dura and canal variation (C-shape). Using a paired t-test, there was significant variation in answers between the first set and second set of questionnaires. Conclusion: It is concluded from this study that general dental practitioners are able to detect radiographic changes when they are extensive but they miss periodontal ligament width and lamina dura changes.

Due to having thorough knowledge on the root canal anatomy and the variations will increase the success of the root canal treatment. Although its most common configuration of the mandibular second molars is having two roots and three root canals. This report presents the endodontıc treatment of a four rooted mandibular second molar, diagnosed with the assistance of cone beam computed tomography .

Clinical and macroscopic study of maxillary molars with two palatal roots

Abstract: Clinicians should be aware of uncommon anatomical variations in maxillary molars. The majority of maxillary first molars have three roots and four canals. Maxillary molars may have two canals in the palatal root.
