Clinical Update quiz
The Clinical Update online is a free member service providing up to 11 FREE CPD hours per year.
Each month, the Clinical Update is published online. There are 11 Clinical Updates per year (February - December). This service is available to ADAVB and ADATas members only. Members can log in to view and answer the Clinical Update questions. If you answer at least eight out of 10 questions correctly, you will receive one hour of scientific CPD.
Please note: Each new Clinical Update will be available below from the first business day of each month.

Introduction
Root canal therapy relies on thorough debridement and filling of the root canal system. A significant factor contributing to persistent endodontic disease is the inability to locate and treat all canals, particularly the second mesiobuccal (MB2) canal in maxillary first molars.
Cone-beam computed tomography (CBCT) provides three-dimensional visualization of dental structures with reduced radiation exposure compared with conventional computed tomography. Where conventional radiographs provide insufficient information, guidelines published jointly by the American Academy of Endodontics and the American Academy of Oral of Maxillofacial Radiology and by the European society of Endodontology suggest use of CBCT in cases of suspected unusual or complex root canal anatomy. A systematic review demonstrated high sensitivity and specificity of CBCT when used to assess root canal anatomy in the MB root of maxillary first molars.
