Background: Root canal morphology varies between the types of the teeth; maxillary teeth are different in their general morphology and termed accordingly as incisors, canine, premolar, and molar. This variation is further subject to classification systems of their root canals.
Methodology: We searched Pubmed for ((root canal) (AND (morphology) OR (anatomy)) OR maxillary tooth))).
Review: Type I of the Vertucci classification is prevalent across all maxillary teeth. This finding is true in populations regardless of geographic location. With the advent of modern imaging modalities such as the cone-beam computerized tomographic scan, the detection of rare morphologies is readily accessible. Hence, the dentist can act accordingly and provide better informed care.
Conclusion: Clinical importance of understanding the potential rare root canal morphologies is mainly to prevent technical errors. When available, the dentist should perform appropriate pre-procedural imaging of the affected tooth.
