Antibacterial and clinical outcome in retreatment of teeth with infection: The impact of pre-operative infection and bacterial reduction on the clinical outcome

32^nd International Conference on DENTISTRY

Keynote: Dentist Case Rep

Abstract :

The reported success rate of endodontic retreatment of root-filled teeth with apical periodontitis has been reported to vary from 62% to 84%. This is 10-20% lower than for initial treatment of necrotic unfilled teeth. The main goal of endodontic treatment is the elimination of the microbial load or its reduction to a level that allows healing to take place. During this presentation, potential causes of failure during endodontic (re)treatment will be discussed. Furthermore, the role of irrigation solutions such as sodium hypochlorite and chlorhexidine at various concentrations will be explored. The focus will be the translation of microbiological research findings into clinical practice. This presentation will explore the impact of preoperative infection and the efficacy of antibacterial treatment during retreatment of previously root canal treated teeth and their long-term prognosis.
