A case of unusual root morphology is presented to demonstrate anatomic variations in mandibular second molars. The most common configuration of mandibular second molar is to have two roots with three root canals; however mandibular molars may have many different combinations. Endodontic therapy was performed in a mandibular second molar with 3 separate roots 2 located mesially and one distally....

BACKGROUND/PURPOSE The objectives of this study were to identify the bilateral distolingual (DL) canals / roots of the mandibular first molars and second mesiobuccal (MB2) canals of the maxillary first molars in the same Turkish individuals using cone-beam computed tomography (CBCT). MATERIALS AND METHODS A total of 150 CBCT images including all mandibular and maxillary first molars were retr...

Maxillary molars present variable root canal and root morphologies. This report describes the endodontic management of two cases of midbuccal canals found in maxillary molars. Midbuccal canals were present in a maxillary first molar with a single buccal root (Case 1), and in a maxillary second molar with three buccal roots (Case 2). An assessment of the internal configuration of these teeth was...

Lactobacillus, a part of the commensal oral microflora, is frequently found in infected root canals but is not considered to be an endodontic pathogen. Lactobacilli have proven to be difficult to identify on species level with biochemical and gene sequencing methods. MALDI-TOF is a new identification method and to our knowledge it has not been used on lactobacilli from infected root canals. The...

Knowledge of the variations in root and root canal morphology is mandatory for the success of endodontic treatment. Neglecting to probe, prepare and fill all the canals can lead to failure of endodontic treatment 1 . As a group the mandibular premolars are among the most difficult teeth to treat endodontically, because they have high incidence of multiple roots or canals 2 . Moreover their root...

Thorough knowledge of root canal morphology is essential for the endodontic therapy. There are rare variations in canal number and configuration in maxillary molars, which could affect treatment outcome. This paper presents the endodontic management of a maxillary first molar with two palatal canals in one root (Vertucci type IV) and a single buccal canal. In this paper cone-beam computed tomog...

The successful outcome of the endodontic therapy requires an adequate knowledge in context to anatomy of the root canal system. In most cases, the mandibular canines are thought to have just one root canal. Those presenting with an extra root and canal are usually rare, ranging from 1% to 5%. Thus, in spite of this low prevalence, variations in the anatomy and number of root canals in mandibula...

Cleaning and shaping are important steps in the root canal treatment. Despite the technological advances in endodontics, K and Hedstroen files are still widely used. In an attempt to be more effective in preparing the root canals, faster and more cutting efficient kinematic, alloys and design alternatives utilizing mechanically oscillating or rotary files are proposed. Even with all these techn...

Root canal systems often have complex anatomy and pose various challenges to every clinician. Research into the morphology of the pulp has revealed that the dental pulp takes many intricate shapes and configurations before reaching the tooth apex like gradual curve, sickle-shaped curve, severe-moderate-straight curve, apical curve, bayonet / S-shaped curve and dilacerated curve, canals emerging...

Background: The education of undergraduate dental students in endodontics should be of high standards to enable newly graduate dentists to deal with the most commonly encountered endodontic clinical problems. Hence, the objective of this study is to evaluate radiographically the quality of root canal fillings done by undergraduate students in the College of Dentistry, King Khalid University, Sa...
