Lateral canals establish connection between the main root canal and periodontal ligament. The necrotic tissues and bacteria residing in the lateral canals are difficult to remove by mechanical and chemical cleaning and this influences filling the root canal efficiently and the outcome of the root canal therapy. The aim of this study was to evaluate the filling of artificially prepared lateral c...

BACKGROUND This study sought to compare the root canal debridement ability of Neolix, Reciproc and ProTaper rotary systems in long oval-shaped root canals. MATERIAL AND METHODS Eighty five extracted single-rooted human teeth with long oval-shaped single root canals were selected and divided into three experimental groups(n=25) and one control group (n= 10). Root canals were filled with Vitape...

AIM C-shaped canal system is a seldom-found root canal anatomy which displays a challenge in all stages of endodontic treatment. According to the literature, this type of canal morphology is not a common finding in the mandibular first molar teeth. BACKGROUND This case report presents endodontic management of a mandibular first molar with a C-shaped canal system. CASE REPORT Root canal syst...

The unique morphology of dilacerated and S-shaped root canals often pose utmost challenges in their endodontic management. Common causes of failures in such cases are primarily related to procedural errors such as ledges, fractured instruments, canal blockages, zip and elbow creations. Knowledge of dental anatomy and its variations is essential for the success of endodontic treatment. A clinici...

The aim of this study was to evaluate the antibacterial activity of 2% iodine potassium iodide (IKI) used as a final rinse after the cleaning and shaping procedures in mesial root canals of mandibular molars infected with Enterococcus faecalis. Seventy two mandibular first molars were used. The root canals were infected with Enterococcus faecalisfor 30 days. After the infection procedures, the ...

background: reinforcement of root canals obturated with resilon was reported by several investigators, but no studies reported the reinforcement of overtly fl ared root canals obturated with resilon material. the aim of this study was to investigate the fracture resistance of overtly fl ared root canals fi lled with resilon as compared to similar root canals fi lled with gutta-percha (gp). mate...

intRODuCtiOn The self Adjusting File (sAF*) system is a new approach to shaping root canal systems, which does not use solid metal files. (Fig 1). The sAF relies on the gentle abrasive action of a flexible mesh lattice to prepare the root canal walls. The sAF offers: 1) the ability to instrument and prepare complex-shaped root canal anatomies; 2) the capability to provide continuous and efficie...

INTRODUCTION This study evaluated the prepared surface areas of oval-shaped canals in distal roots of mandibular molars using four different instrumentation techniques. METHODS Teeth were prescanned and reconstructed using micro-computed tomography (MCT) scans at low resolution (68 microm). Forty-eight molars with ribbon-shaped/oval distal root canals were selected and randomly assigned to fo...
