Complications due to medicaments

Abstract

Medicament uses in root canal system are of so many varieties and have effects on both pulpal tissues and microbial flora not just inside the root canal system but the periodontium as well. That is why when choosing any medicament, the clinician must make the right choice. Choose a medicament which has an effect on the microorganisms, as this is the most important factor in root canal failures and it should have the least effect on the tissues surrounding the root. The medicament should be confined in the root canal system during its use, and care should be taken not to expel it beyond the root apex into the periapical tissues. In case this happens, damage to the periapical tissues ensues leading to inflammation, swelling and probably tooth loss.
