INTRODUCTION The failure of primary endodontic treatment is manifested by various clinical symptoms following endodontic therapy or, more frequently, by the development of chronic inflammatory process in the apex region without any subjective symptoms. In case of unfavorable outcome of the primary endodontic treatment, orthograde endodontic retreatment is the method of choice for a prolonged th...

PURPOSE To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. METHODS Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling materia...

Modern endodontic surgery involves both root-end preparation and proper sealing of all apical portals of exit. Both components are requirements for mechanical and biological success, but the management of soft tissues becomes increasingly important for an esthetically successful treatment. A healthy appearance of soft tissues plays an important role in the esthetic outcome of periradicular surg...

INTRODUCTION Teeth undergoing initial endodontic therapy have a very high survival rate. Some teeth that continue to show signs of pathosis after the initial therapy will require nonsurgical (orthograde) retreatment. Outcome assessment of endodontic retreatment is crucial for appropriate case selection and treatment planning. However, reports on outcomes of orthograde endodontic retreatment per...

ABSTRACT Introduction: Endo perio lesions are common conditions that are often difficult to diagnose and are persistent if not treated completely. However, if the patient’s history is taken carefully and thorough evaluation of all possible routes of infection is carried out, a properly done endodontic treatment is sufficient to eliminate the infection. However, wherever a secondary periodontal ...

introduction : the purpose of this clinical study was to compare the blood mercury levels before and after endodontic surgery using amalgam as a root-end filling material. materials and methods: fourteen patients requiring periradicular surgery participated in this prospective clinical study. a zinc-free amalgam was employed as root-end filling material. blood samples were collected at three in...

Biofilms are multicellular communities which composed of prokaryotic and/or eukaryotic cells embedded in matrix. More than 500 bacterial species have been identified dental biofilms, pose a harmful risk to health. Isthmus is ribbon-shaped communication between two root canals contains pulp tissue.
