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

TL;DR

A modified triple antibiotic paste successfully treated a large dental infection without surgery, offering a less invasive alternative.

Contribution

The paper presents a successful non-surgical application of a modified triple antibiotic paste for treating periapical lesions.

Findings

The modified TAP effectively eliminated germs from the root canal system.

Non-surgical treatment is a viable first-line approach for periapical lesions.

The paste provides broad-spectrum antimicrobial activity against endodontic infection bacteria.

Abstract

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. Men are more likely to be affected by this infection than women. There are two modalities for the treatment of periapical lesions: surgical or non-surgical endodontic therapy. The modified triple antibiotic paste (TAP) comprising ciprofloxacin, metronidazole, and clindamycin in the ratio of 1:1:1 was first prepared expressly to treat the teeth with necrotic pulp and to support the protocol for revitalization and regrowth. The treatment was very successful in eliminating germs from the root canal system. It provides broad-spectrum antimicrobial activity against a wide range of bacteria commonly associated with endodontic infections. The modified TAP is usually inserted into the canal for a predetermined amount of time and then removed followed by the irrigation of root canal, which helps to eliminate the microorganisms from the root canal. The non-surgical treatment should always be the first choice over the surgical approach so as to avoid a more invasive procedure.
