BACKGROUND Knowledge about root canal morphology and its frequent variations can exert considerable influence on the success of endodontic treatment. The aim of this study was to survey the root canal morphology of mandibular first premolar teeth in a Gujarati population by decalcification and clearing technique. METHODS One hundred thirty eight extracted mandibular first premolar teeth were ...

The aim of root canal preparation is to clean and shape the root canal system while maintaining the original configuration. However, traditional hand instruments often failed in achieving these objectives, especially when used in severely curved canals. Over the years, many nickel-titanium rotary instruments have been developed to improve root canal preparation. More flexible files made of nick...

INTRODUCTION Advantages of endodontic treatments over tooth extraction have increased the demands for these treatments. Success rate of these treatments is generally lower than the primary root canal therapies. Recently, single visit treatments have gained more popularity. But, the influence of completing retreatment in a single appointment on success of the treatment is still a controversy. Th...

STATEMENT OF PROBLEM The knowledge of the pulp anatomy plays an important role in the success of endodontic treatments. PURPOSE The aim of this study was to determine the root and canal morphology of the mandibular second molar teeth in an Iranian population. MATERIAL AND METHODS One hundred intact human mandibular second molars were collected. The teeth were examined visually and the numbe...

Despite the advantages of cone-beam computed tomography (CBCT), the images provided by this diagnostic tool can produce artifacts and compromise accurate diagnostic assessment. This paper describes an endodontic treatment of a maxillary molar where CBCT images suggested the presence of a nonexistent third root canal in the palatal root. An endodontic treatment was performed in a first maxillary...

AIMS (i) To carry out meta-analyses to quantify the influence of the clinical factors on the efficacy of primary root canal treatment and (ii) to identify the best treatment protocol based on the current evidence. METHODOLOGY The evidence for the effect of each clinical factor on the success rate (SR) of primary root canal treatment was gathered in three different ways: (i) intuitive synthesi...

The maxillary first molar usually has single palatal root. Incidence rate of maxillary first molar with two palatal roots is especially rare. We reported a case of young maxillary first molar with two palatal roots in this article. Anatomic characteristic of permanent maxillary molar is generally described as a group of teeth with three roots, one palatal and two buccalbut the root canal system...
