Preliminary investigation to achieve patency of MB2 canal in maxillary molars
Aim: To establish a preliminary investigation about the possibility to achieve patency of second mesiobuccal canal (MB2) in mesiobuccal roots of maxillary molars. Methods: Three hundred and five first maxillary molars were examined with direct vision and with magnification. The root canal configurat...

Methods: Three hundred and five first maxillary molars were examined with direct vision and with magnification.
