“…La literatura muestra que los métodos anatómicos ex vivo son más precisos en demostrar la configuración interna del SCR que los métodos ex vivo (Sert & Bayirli; Cleghorn et al; Hiebert et al), sin embargo, el estudio de identificación de MV2 es de necesidad clínica, por lo tanto se deben complementar técnicas diagnósticas de imagenología e incorporar magnificación para mejorar la capacidad clínica de identificación de MV2. Para el endodoncista, el método diagnóstico ideal para esta condición es la TCCB porque entrega resultados morfológicos más confiables que la radiografía panorámica y periapical (Blattner et al, 2010;Martins & Versiani, 2018;Martins et al, 2019) y el uso de microscopio facilita la localización y negociación del acceso a MV2 (Görduysus et al, 2001 MV2 aumenta de 51 % a 82 % cuando el clínico trabaja con microscopio. Los resultados del presente estudio concuerdan con las recomendaciones clínicas reportadas en la literatura al mostrar que las técnicas diagnósticas alternativas al corte dentario demostraron una prevalencia de 81,8 % para la TCCB, 59,4 % para la apertura cameral con microscopio y un 32,6 % para la radiografía ortoradial.…”

RESUMEN: Los objetivos principales del tratamiento de endodoncia no quirúrgico son la prevención y/o tratamiento de periodontitis apical junto con la resolución de signos y síntomas de las lesiones pulpares irreversibles. Debido a la compleja morfología del sistema de conductos radicular, la persistencia de un conducto no tratado puede mantener la contaminación y sintomatología pulpar y periapical. La prevalencia para MV2 reportado a nivel mundial para el primer molar superior varía ampliamente según las técnicas in vivo o ex vivo empleadas en cada estudio, es por esto que el presente trabajo tiene por objetivo evaluar la prevalencia de MV2 en primeros molares superiores en base a cuatro técnicas diagnósticas aplicadas ex vivo. Se realizó un estudio transversal observacional en 101 primeros molares superiores extraídos bajo consentimiento informado para determinar la prevalencia del conducto MV2 y su morfología en base a las técnicas de radiografía ortoradial, tomografía Cone Beam, apertura coronaria con microscopio quirúrgico (16x) y cortes radiculares axiales de aplicación ex vivo. La prevalencia encontrada para MV2 por cada técnica fue de 81,1 % para cortes radiculares y tomografía Cone Beam, 59,4 % para la apertura coronal con microscopio (16x) y 32,6 % con radiografía ortoradial. En el 3,96 % de la muestra se encontró un tercer conducto mesiovestibular en base a la técnica de corte radicular. La morfología interna del sistema de conductos radiculares fue de 36 % clase II, 19 % clase I y 16 % clase IV de Vertucci. Los resultados del presente estudio están en concordancia con lo reportado en la literatura y confirman la mayor prevalencia reportada en estudios ex vivo para esta situación. La presencia de MV2 en el primer molar superior es una condición frecuente que el endodoncista debe considerar, empleando técnicas imagenológicas y tecnologías de magnificación para asegurar el éxito terapéutico en estos dientes.

A successful endodontic treatment depends on a comprehensive knowledge of the morphology of canal and its variations, an appropriate access cavity, cleaning and shaping, and adequate root canal filling. Lack of knowledge in this regard and missing a root canal are among the most common causes of failure of root canal treatments. Most previous studies on maxillary molars have reported that they usually have three roots and four canals since an extra canal is often found in the mesiobuccal root. Other anatomical variations, such as an extra C-shaped canal, have also been reported in distobuccal and palatal roots. Thus, because of having a more complex anatomy compared to other teeth, maxillary molars have the highest rate of endodontic failure. Several studies have assessed the morphology of root canal anatomy in different populations using different techniques such as sectioning, root canal clearing, association of a dental operating microscope and ultrasonic tips, periapical radiography, and computed tomography scanning. Recently, CBCT was suggested to three-dimensionally explore the root canal details before an endodontic treatment. The purpose of this chapter was to highlight the importance of having a thorough knowledge about the root canal morphology of the permanent first and second maxillary molar.

Dental anatomy is an integrated, core fundamental dental course, which prepares students for all future clinical dental courses. This study aimed to build up an online dental learning platform of micro‐computed tomography‐based three‐dimensional (3D) tooth models with pulp cavity, and to further evaluate its effectiveness for dental anatomy education using a cohort study. First, ninety‐six extracted permanent teeth were scanned by micro‐computed tomography and the enamel, dentine, and pulp cavity of each was distinguished by different grey‐scale intensities using Mimics software. Three‐dimensional images allowed further discrimination and insights into permanent three‐rooted premolars, central tip, and dental diseases including deep caries and wedge‐shaped defects. Furthermore, a second mesiobuccal canal (MB2) in maxillary permanent molar teeth and Vertucci type III root canal configuration in mandibular anterior teeth could be detected using the 3D analytical tool. A digitized 3D tooth model learning platform was implemented. Last, two groups of dental students were assessed to evaluate the effect of 3D models on dental anatomy education. Participants in the Digital group were allowed to use the online dental learning platform freely after class, while the participants in the Traditional group were not. Assessment quizzes showed that participants' scores improved in the Digital group with the use of the learning platform compared with scores in the Traditional group. A questionnaire survey indicated that the participants had a positive attitude toward the 3D models. Thus, adding digital 3D resources to a traditional curriculum may have a positive effect on academic achievements.
