Careful understanding of internal anatomy of root canal system is crucial for successful endodontic treatment. The presence of two palatal canals in maxillary second molar is unusual but noteworthy as an aid to appropriate diagnosis and treatment. This paper reported a case of a maxillary right second molar with two root canals in the palatal root. The root canal treatment and case management w...

BACKGROUND Aberrations in the root canal anatomy are clinically challenging for clinicians. Mandibular first molars usually have 2 roots and 3 or 4 canals, but various combinations may exist. A distal root with three canals is rare and its incidence in literature is about 0.2 - 3%. As a diagnostic tool, cone-beam computed tomography (CBCT) may be a better choice for diagnosis of extra roots or ...

OBJECTIVE Our goal in this study was to evaluate the antimicrobial effect of Er:YAG laser applied after biomechanical preparation of the root canals of dog's teeth with apical periodontitis. BACKGROUND DATA Various in vitro studies have reported effective bacterial reduction in infected root canals using Er:YAG laser. However, there is no in vivo research to support these results. METHODS F...

INTRODUCTION Cleaning and shaping without making procedural errors have always been a challenge in endodontics, particularly when the root canals are curved. Several rotary instruments have been developed to minimize such errors. The purpose of this study was to compare the shaping ability of 2 rotary file systems, BioRace (BR; FKG, La Chaux-de-Fonds, Switzerland) and ProTaper Next (PTN; Dentsp...

Objectives: This in vitro study aimed to compare the volumes of unfilled areas oval-shaped root canals filled with five different obturation techniques after minimally invasive canal shaping using cone beam computed tomography (CBCT). Materials and Methods: 50 extracted mandibular premolars were used. Root instrumented K3 files (Kerr, USA) size #30.04. Then, samples randomly distributed into gr...

he purpose of the present study was to evaluate the influence of some auxiliary agents of biomechanical preparation of the root canal on the filling of artificial lateral canals in extracted human teeth. A total of eighty single-rooted teeth were employed, which were submitted to preparation of three artificial lateral canals in one of the proximal aspects at the cervical, middle and apical thi...

introdouction: variations in root canal morphology pose a challenge for successful endodontic treatment. the root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). the occurrence of two palatal canals in one palatal root is quite rare. this report represents the case of a maxillary first molar...

statement of problem: sodium hypochlorite (naocl) have been widely used as an irrigant since it has been introduced to endodontics by walker in 1936, because of its bleaching, deodorizing and tissue dissolving properties. it should be used clinically in concentrations of 3% to 5%. purpose: the aim of this study was to evaluate the effectiveness of the naocl to eliminate enterococcus faecalis (e...

UNLABELLED As is commonly understood, the root canal morphology of the maxillary molars is usually complex and variable. It is sometimes difficult to detect the distobuccal root canal orifice of a maxillary second molar with root canal treatment. No literature related to the distobuccal root canals of the maxillary second molars has been published. OBJECTIVE To investigate the position of the...
