The purpose of the mechanical root canal preparation is to clean it and give right shape. should be carried out in a way that maintains original curvature initial orientation apical end. Insufficient may prevent effective chemical decontamination obturation full working length. study aims evaluate shaping ability effectiveness NiTi rotary reciprocating endodontic instruments, compared standard ...

The unique morphology of dilacerated and S-shaped root canals often poses utmost challenges in their endodontic management. Dilaceration is defined as developmental anomaly which there has been an abrupt change the axial inclination between crown a tooth. Periapical radiographs CBCT are most appropriate way to diagnose presence dilacerations. Also, clinician required have insight tooth related ...

BACKGROUND Efforts to improve the performance of rotary NiTi instruments by enhancing the properties of NiTi alloy, or their manufacturing processes rather than changes in instrument geometries have been reported. The aim of this study was to compare in-vitro the shaping ability of three different rotary nickel-titanium instruments produced by different manufacturing methods. METHODS Thirty s...

Pulp stones are usually found in the pulp chamber. Radiographically, they appear as radiopaque structures in the pulp chambers or root canals of individual teeth. Generalized pulp stones throughout the dentition are usually associated with systemic or genetic disorders of the dentine. This report presents an unusual case of a 13-year-old girl with generalized pulp stones with clinically normal ...

The aim was to compare the canal straightening of M-wire [Reciproc (VDW, Munich, Germany)] and blue-wire heat-treated Blue (VDW) instruments in simulated resin L-shaped curved root canals. A total 26 canals with curvature 45° length 17 mm (#15-0.02 taper) endo training blocks were divided into two groups (n = 13). All prepared an apical size 25 according manufacturers’ instructions. Pre- post-i...

The light microscopic features of the dentine in three teeth from two cases of osteogenesis imperfecta (OJ) are presented. Results show that teeth in OJ distinctively have a more uniform and tubular mantle dentine, and a characteristic laminated circumpulpal dentine formed by distorted incremental bands alternating with parallel rows of interglobular dentine and interrupted by comet-shaped vasc...

Introduction: The aim of this article was to emphasize the importance of variations in root canal anatomy. Methods: This case report presents the endodontic management of a maxillary first molar with c-shaped palatal canal bifurcating into two canals at the middle third and exiting from a single apical foramen. The canal morphology was confirmed with the aid of cone beam computerized tomography...

The mandibular first molar (MFM) commonly presents two roots with canals in the mesial root and one or distal root. However, morphological variations have been described different populations, which must be considered when planning endodontic treatment. aim of this study was to analyze internal external morphology MFM a Chilean sub-population using cone-beam computed tomography (CBCT) images. A...

The objective of the present study was to assess the effectiveness of reciprocating instrumentation in disinfecting oval-shaped root canals infected with Enterococcus faecalis. Forty-five human lower premolars were infected with a culture of E. faecalis (ATCC 29212) for 28 days. Five other teeth that were neither contaminated nor instrumented were used as controls. The 45 specimens were divided...
