Introduction Dentinal damage and cracks induced by orthograde preparation methods have been reported in studies using extracted teeth. The purpose of this in situ investigation was to evaluate dentinal cracks in nonextracted teeth after final instrum

The aim of this study was to compare the root canal debridement ability of the self-adjusting file (SAF) with ProFile rotary (PF) and hand filing (HF) instrumentation in long-oval-shaped canals.Extracted human teeth (n = 30) were selected on the basi

Large through-and-through lesions have been reported to heal faster and better when filled with bone graft material at the time of an apicoectomy. It is unknown what effect these have on retrograde filling materials such as white mineral trioxide agg

Introduction Mineral trioxide aggregate (ProRoot [PR]; Dentsply, Tulsa, OK) has been shown to have high rates of success in various endodontic applications. A major drawback is its tendency to discolor dentin. Two new bioceramics (BD, Biodentine [BD]

The results of instrumentation studies in small curved canals using various instruments and techniques are not consistent. The amount of instrument precurving and a gradual or abrupt curve of the canal may have influenced the results of these studies
