Root canal filling materials, including sealercement and obturation points or cones, are used in root canal treatment to occlude the apical portion of the canal. These will block the dentinal tubules preventing passage of tissue fluids, toxins, and microorganisms into the root canal space. Many investigators have demonstrated the importance of a sealer cement for effective root canal obturation...

The purpose of this study was to conduct a cone-beam computed tomographic (CBCT) investigation on the root and canal configuration of the mandibular first molars, especially the morphology of the disto-lingual (DL) root, in a Chinese subpopulation. A total of 910 CBCT images of the mandibular first molars were collected from 455 patients who underwent CBCT examinations as a preoperative assessm...

Effective germ elimination during endodontic treatment is absolutely necessary1,2 because treatment failure can often be attributed to the inadequate reduction of germs. The bacterial flora in endodontic infections is related to the flora in the oral cavity and has a bacterial population of between 102 and 107 different germs per infected root canal.3 Since mechanical preparation of the root ca...

The main objective of root canal treatment is thorough mechanical and chemical cleansing of the entire pulp space and to provide an intact hermatic seal. A 30 year-old female patient was referred to the Department of Conservative Dentistry and Endodontic with a chief complaint of acute pain in her right lower back tooth. From the clinical and radiographic findings, a diagnosis of symptomatic ir...

AIM To highlight anatomical variation in the mandibular canine. SUMMARY Two clinical case reports are presented to illustrate anatomical variation in the human mandibular canine. Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment procedures. Many investigators have reported the anatomical variations associated with mandibular can...

An accurate diagnosis of the morphology of the root canal system is a pre-requisite for successful root canal treatment. Frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have anatomical variations or additional root canals. In this report a maxillary lateral incisor with two roots has been described.

Aims Since the inception of the cleaning and shaping concept, the use of instruments and chemicals has remained as the central paradigm of the root canal therapy. However, cleaning and shaping the root canal space adequately is a well-known difficult task, particularly in root canal systems with intercanal connections, isthmuses, and fins. Recently, micro-computed tomography (micro-CT) technolo...

BACKGROUND AND AIMS The knowledge of variations in root canal morphology is critical for a successful endodontic treatment. The purpose of this study was to investigate variations in the root canal system of human mandibular first permanent molars in an Iranian population. MATERIALS AND METHODS In this study, 209 mandibular first molar teeth were decalcified, dye-injected, and cleared in orde...
