OBJECTIVES The aim was to evaluate dentinal crack formation after root canal preparation with ProTaper Next system (PTN) with and without a glide path. MATERIALS AND METHODS Forty-five mesial roots of mandibular first molars were selected. Fifteen teeth were left unprepared and served as controls. The experimental groups consist of mesiobuccal and mesiolingual root canals of remaining 30 teet...

AIM To compare in vitro the cleanliness of root canal walls in oval-shaped root canals following automated or manual instrumentation. METHODOLOGY Forty-five oval-shaped single-rooted maxillary and mandibular premolars with straight canals were divided into three groups of 15. Automated canal preparation was performed using Anatomic Endodontic Technology (AET, group 1) and the ProFile system (...

OBJECTIVE The aim of this study was to investigate the root and canal morphology of maxillary third molars in Central India population using cone-beam computed tomography (CBCT) analysis. MATERIALS AND METHODS CBCT images of 116 maxillary third molars were observed, and data regarding the number of roots, the number of canals, and Vertucci's Classification in each root was statistically evalu...

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...

Introduction: The purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. Methods: Sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. The teeth were sectioned at a 10 mm distance from the apex. After instrumentation, the teeth were divided into 3 gr...

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...

conclusions most extracted maxillary first molars were three rooted and four canals. cbct has relatively high reproducibility and accuracy of distinguishing mb2 canal. results we found 100% of cases with three separated roots, from which 69.23% had four canals including mb2 and 30.77% with three canals. 71.3% of mesiobuccal roots were two canals of type two vertucci and 28.7% type 4 with the me...

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...

For the successful root canal treatment, thorough cleaning and shaping of the root canal system is a necessary procedure. C-shaped canals are known to have a complex canal anatomy with numerous fins connecting individual canals, thus require supplementary effort to accomplish a successful root canal treatment. Generally, anthropologic differences in tooth shape is not an important issue in the ...

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...
