Treatment of chronic apical periodontitis in which canal secretion persists

Abstract

Introduction. Chronic apical periodontitis presents destructive periapical lesions of a varied extent, occurring in areas of a minor but long-lasting infection, often leading to the development of fistulas in places of low resistance. The occurrence of pus discharge is a sign of a reaction to a pathogenic bacterial infection, and the presence of purulent discharge in the canal impedes the root canal filling. Aim of study. To determine the effectiveness of curative calcium-hydroxide dressings with iodoform in the regeneration of periapical tissues and therapeutic tactics in teeth with a persistent purulent discharge in the root canals. Methods and materials. A group of 15 patients were clinical and paraclinical examined, being subjected to endodontic root canal treatment with calcium-hydroxide paste containing iodoform over a period of 1-3 weeks. Iodine released from the medicated paste helped sterilize the root system and remove the purulent discharge from the root canals. Results. Medicated calcium-hydroxide dressings with iodoform applied in the root canals over a period of time destroy the pathogenic flora in the root system, having a favorable prognosis. Conclusion. The clinical study highlighted the importance of medicated calcium hydroxide dressings with iodoform as an effective remedy for teeth with a purulent discharge in the root canals. extent, occurring in areas of a minor but long-lasting infection, often leading to the development of fistulas in places of low resistance.
