Non-surgical Management of a Large Periapical Lesion: A Case Study of the Successful Application of a Modified Triple Antibacterial Paste.

Infection of the dental pulp involves mainly Gram-negative, anaerobic bacterial flora and due to this infection, the periapical area experiences an immunological response, which is termed a periapical lesion. This lesion may appear as a radiolucent (dark) area on X-rays, which indicates periapical inflammation and infection. Its prevalence depends on factors such as age, oral health maintenance, and dental care.

A C-shaped canal describes an anatomical configuration of a tooth's root canal that resembles the alphabet C when viewed occlusally in a prepared access cavity. In the second molar of the maxillary arch, the root canals unite into a single, continuous, extensive root canal morphology to form a C-shaped canal. The natural crevices found in tooth roots where blood vessels and nerves are housed are called root canals.
