Bioceramics has significantly higher success rates than amalgam , but they were statistically similar to intermediate restorative material ( IRM ) and Super ethoxybenzoic acid ( Super EBA ) when used as retro grade filling material s in apical surgery .
However , it seems that the high success rates were not solely attributable to the type of the root-end filling material s. The surgical/microsurgical techniques and tooth prognostic factors may significantly affect treatment outcome
Introduction Periradicular surgery involves the placement of a root-end filling following root-end resection , to provide an apical seal to the root canal system .
Historically several material s have been used in order to achieve this seal .
Recently a class of material s known as Bioceramics have been adopted .
Periradicular Surgery of Human Permanent Teeth with Calcium-Enriched Mixture Cement
Introduction Root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible . The present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture ( CEM ) cement . Material s and Methods A prospect i ve outcome study of periradicular surgery using CEM was conducted on 14 permanent teeth with persistent apical periodontitis . Using a st and ardized surgical protocol , 2 - 3 mm of the root apex was resected ; approximately 3 mm deep root-end cavities were ultrasonically prepared and filled with CEM cement .  All patients were available for recall . Results Clinical and radiographic examination revealed complete healing of periradicular lesions , i.e. regeneration of periodontal ligament and lamina dura in 13 teeth ( 93 % success ) during a mean time of 18 months ; moreover , the teeth were functional and asymptomatic . Conclusion Favorable treatment outcomes in this prospect i ve clinical study suggested that CEM cement may be a suitable root-end filling bio material
