For several decades, the endodontic community strongly believes that large cyst-like periapical lesions and apical true cysts are most likely not able to heal through conservative root canal treatment alone. However recently literature starts supporting the conservative approach where large cyst-like periapical lesions had favorable clinical and radiographic responses to nonsurgical endodontic treatment protocols. Although the treatment can be extended for several months.
Objectives
- Describe clinical and radiographic outcomes of large cyst-like lesions that were treated by orthograde decompression and long-term intracanal use of calcium hydroxide
- Discuss different management protocols that can guarantee the healing of large cystic periapical lesions.
- Evaluate the association between long-term Ca (OH)2 use and the incidence of fractures during the long-term management of cystic like lesions.
