“…In a case series in which five teeth, maxillary first and second molars, with bifurcated palatal canals were identified, the authors highlighted that the assumption of a single canal in all palatal roots of maxillary molars needs to be changed [ 32 ]. Within this context, a study [ 33 ] identified five cases of second molars with two or three canals in the palatal root. The findings of the present study corroborate the results of these authors since variations were observed in the morphology of the palatal canal, especially when the classification proposed by Vertucci [ 15 ] was used.…”

The aim of this study was to evaluate the root canal morphology of permanent maxillary molars by cone-beam computed tomography (CBCT) using the classifications of Weine et al. and Vertucci and to correlate the findings with sex, age, position in the dental arch, and prevalence of a second canal in the mesiobuccal root (MB2). A total of 414 scans were evaluated, corresponding to 1,000 teeth. The assessment consisted of coronal, axial, and sagittal reconstructions using i-CAT Workstation®. Type 0 was assigned when neither classification could be applied. The data were entered into an Excel spreadsheet and analyzed using SPSS. The chi-squared test or Fisher’s exact test was used to compare the distribution of root canal morphology classified using the two systems. Analysis of the distribution of Weine types showed a predominance of type III in mesiobuccal roots, while type 0 predominated in distobuccal and palatal roots. Vertucci type IV predominated in mesiobuccal and distobuccal roots and type VII in palatal roots. There was no difference in the distribution of morphological canal types in permanent maxillary molars evaluated by CBCT according to sex, age group, or position in the dental arch of the patients. MB2 canals were identified in 68.4% of the teeth evaluated.

“…22 This tool can be especially useful when it is possible to identify independent entrances for each canal. 23 Buhrley et al 24 concluded that when the maxillary first molars were considered separately, the frequency of MB2 canal detection for the microscope, dental loupes, and no magnification groups were 71.1%, 62.5%, and 17.2%, respectively. Baldssari-Cruz et al 25 evaluated 39 maxillary molars in vitro and concluded that the surgical operating microscope did aid in the identification of mesiolingual canal orifices.…”

Aim: This Case Report describes two rare cases of clinical management of maxillary first molars with six root canals with special reference to radiographic interpretation and diagnosis. Background: The study reports 2 clinical cases of endodontic treatment of maxillary first molars with six root canals. Case Description: The access cavity was prepared using a slow speed round bur. The teeth were diagnosed with irreversible pulpitis and then anesthetized for an endodontic access cavity preparation. Clinical evaluation of the internal anatomy revealed 3 principle root canal systems: mesiobuccal (MB), distobuccal (DB), and palatal in each tooth. The working length was determined and the radiographs were taken for all the roots i.e mesiobuccal, distobuccal and palatal separately after placing instruments in each. The cleaning and shaping was performed using ProTaper Universal rotary instruments. Irrigation between each instrument was done. The canals were dried and obturation was performed using cold lateral compaction of gutta-percha and a resin-based sealer. The teeth were then restored with a posterior composite restoration. The patients were advised a full-coverage crown. Conclusion: A good knowledge of tooth morphology, careful interpretation of angled radiographs, proper access cavity preparation and a detailed exploration of the interior of the tooth is needed to ensure a proper endodontic treatment. Clinical Significance: Prevalence of teeth with such complex internal anatomy is a rare anomaly. However, a sound knowledge of the internal anatomy can aid in its adequate management. Keywords: maxillary molar, six canals, altered anatomy

“…Ozcan, Aktan e Ari (2009) descreveram a incomum anatomia de um segundo molar superior com três canais mésiovestibulares. Em outro estudo, Scarparo et al (2011) identificaram cinco casos de segundos molares com dois ou três canais na raiz palatina, além de duas raízes palatinas distintas. Zhao et al (2011) apresentou um caso de um segundo molar com três raízes mésiovestibulares e outro de um terceiro molar com quarto raízes independentes.…”

Introdução: o tratamento endodôntico visa manter o dente na cavidade bucal mesmo com a perda de sua vitalidade pulpar. No entanto, a ocorrência de variações na anatomia dental pode dificultar e/ou comprometer a eficácia do tratamento. Objetivo: realizar uma revisão da literatura acerca das variações anatômicas que podem interferir no tratamento endodôntico. Revisão: relatos de diferentes tipos de variações anatômicas acometendo todos os elementos dentais foram encontrados na literatura, além de diferentes métodos diagnósticos auxiliares. Conclusão: para um tratamento endodôntico de sucesso, é essencial ter amplo conhecimento da anatomia dental, pois qualquer elemento dentário pode ser acometido por variações na sua anatomia. Cabe ao cirurgião dentista, na prática clínica, sempre desconfiar da existência dessas variações e fazer uma investigação criteriosa para que seja possível estabelecer corretamente o diagnóstico e definir a abordagem terapêutica mais apropriada.
