Root canal anatomy: an online study guide.

The Editorial Board of the Journal of Endodontics has developed a literature-based study guide of topical areas related to endodontics. This study guide is intended to give the reader a focused review of the essential endodontic literature and does not cite all possible articles related to each topic. Although citing all articles would be comprehensive, it would defeat the idea of a study guide. This section will review articles related to root canal anatomy including classification systems, individual teeth reviews, furcation canals, apical anatomy, dental anomalies, and demographic/geographic analysis.
