On the MB2 trail

A carious exposed 16 requiring Endodontic treatment.

Initial working length determination using hand files.

Closer inspection of pulpal floor reveals another Mesiobuccal orifice. A faint canal can also be seen on radiograph.

The incidence of MB2 canal in Maxillary Ist & 2nd Molars is quite high and time should be devoted to to its location and treatment. 

Both MB canals have been located. It exibits a Type III  canal anatomy.

Post obturation radiograph .Protaper rotary files were used for canal preparation. 

Post obturation radiograph taken from another angle to see better separation of canals. 

Wrong turn !

A patient reports with symptoms of  pulpitis and apical periodontitis in 47. The tooth has a # filling.

 An obstruction is encountered in  the apical third of distal canal.

A precurved file and tactile feeling help negotiate a sharp distal bend in the apical third.

The distal canal is prepared by hand filing in the  apical third and Protaper rotary in coronal and middle third.

Mesial root has a Type II canal anatomy and is prepared with Protaper rotary files.

                                               

After final Obturation using 6% G.P.as master cone and lateral condensation technique.
