Endodontic therapy of mandibular molars is a challenging task due to its varied root canal morphology. A mandibular first molar with additional buccal root (Radix paramolaris) and additional distolingual root (Radix Entomolaris) is an example of its varied anatomy. A successful management of atypical root canal configurations is an important aspect in determining the success rate of root canal ...

INTRODUCTION To achieve success in treatment, one cannot ignore the knowledge of pulp anatomy. Mandibular premolars are considered to be the most difficult teeth for endodontic therapy due to high variability in their canal morphology. It is possible that a relation exists between the crown size and the number of extra canals in these teeth, so this in vitro study aims to investigate the relati...

presence of extra roots and canals should be considered before initiation of root canal treatment for the success of endodontic treatment. a mandibular second premolar with three separate roots is very rare and its prevalence has been reported to be around 0.1%. this case report explains non-surgical endodontic treatment of a mandibular second premolar with three separate roots and three separa...

INTRODUCTION The knowledge of root canal anatomy is essential to ensure a successful outcome of surgical and nonsurgical root canal treatment. The aims of this article were to present 2 cases of maxillary molars with 3 mesiobuccal root canals and to review the available literature on this anatomic variation. METHODS The first case described a nonsurgical root canal treatment of tooth #16 in a...

A clear understanding of the anatomy of human teeth becomes an essential prerequisite for achieving success in endodontic treatment. The presence of an untreated canal may be a reason for failure. The importance of developing a visual picture of the expected locations and number of canals in a particular tooth can’t be overlooked. This report describes a mandibular first molar with unusual root...

Background: Internal anatomy of maxilary first premolars is particularly multifaceted on account of the variation in number of roots and canal configuration. Maxilary first premolars with 3 roots are caled as smal molar or “radiculous” because of their similar anatomy to the maxilary first molars. The most demanding step in endodontic treatment is identification and proper access to pulp canals...

OBJECTIVES The objective of this study was to evaluate the efficacy of erbium-doped yttrium aluminum garnet (Er:YAG) laser irradiation in different energy outputs versus ultrasonic in gutta-percha removal during the endodontic retreatment. MATERIALS AND METHODS A total of 21 extracted human lower premolars were divided into three groups (n = 7). Following the standardized preparation of the r...

BACKGROUND Bacteria like E. faecalis can produce intra- and extra-radicular biofilms. Theoretically, the adjustable penetration ability of lasers enables better access to root canal system. Therefore the aim of the present study was to compare the ability of photoactivated laser and 2.5% NaOCl irrigation solution to eliminate E. faecalis from the root canals by real-time PCR technique. MATERI...
