Abstract
The Upper first molar is one of the most complex and difficult teeth to treat in the oral cavity due to its root canal configurations. It could have one canal to eight canals. It may have a single root to four roots. The location of the MB2 canal in the maxillary first molar is more complex due to its variable position (Near MB1 to the Palatal canal) and narrow foreman/orifice than any other root canal system in the oral cavity. That is why it hard to locate by most dentists. Therefore, MB2 is one of the most missing canals in the upper molars that can lead to RCT failure sooner or later. Up to 95 per cent of the maxillary first molars contained at least four canals that required instrumentation to avoid RCT failure.
In the past century, the incidence of MB2 was found from 50% to 98% in various studies. It is said that Cone Beam Computed Tomography (CBCT) scanning is the most vital resource in the assessment of root canal systems notably to identify MB2 canals in maxillary molars.
