Regenerative Endodontics Using Different Intracanal Medicaments on Radiographic Outcomes and Periapical MMP-8 Levels
Summary
Two-session regenerative endodontic treatment was applied to 20 immature mandibular first molars with symptomatic irreversible pulpitis and symptomatic apical periodontitis. At the end of the first session, calcium hydroxide \[Ca(OH)2\] was applied to 10 randomly selected teeth and double antibiotic paste (DAP) intracanal medicaments were applied to the other 10 teeth. The effects of intracanal medicaments on periapical MMP-8 levels were determined by immunofluorometric assay (IFMA) in periapical tissue fluid samples taken from the distal root canal in the first and second sessions.
