Abstract:

As a small branch from the root canal，the lateral branch canal is often perpendicular to the root canal，penetrating the dentin and the cementum and leading to the periodontal ligament. As a part of the anatomical structure of the root canal，the lateral canal is closely related to the success rate of the root canal treatment. This review discusses briefly the formation and distribution of the anatomical structure of the lateral canal，imaging findings，cleaning and disinfection，the influence of its filling on the root canal and its relationship with periapical diseases.

Key words: lateral canals, anatomic structure, root canal therapy, periapical diseases
