Endodontic Management of Mandibular anterior teeth and premolars with Vertucci's Type VIII canal morphology: A Rare Case.

A thorough knowledge of variable and complex tooth morphology, detailed exploration of the internal anatomy and underlying pathology, proper interpretation of radiographic images, conservative access to explore all the canals, thorough debridement and disinfection of canal system, three-dimensional seal by obturation, and good coronal seal by final restoration are essential steps in the management for a successful endodontic treatment outcome. Clinical management of rare case with extra canals in the lower anterior teeth and premolars had to undergo root canal therapy has been described. Referring to the hard-tissue repository of the human dental internal morphology, carefully interpreting multiangled radiography/cone-beam computed tomography, using tools such as magnifying loupes with illumination and ultrasonics, thermoplasticized gutta-percha system to obturate, are very helpful to the clinician can achieve this goal. This article describes and illustrates the management of a rare case with Vertucci's Type VIII canal anatomy in lower anterior teeth and premolars.

Biofilm models in endodontics-A narrative review.

The knowledge of biofilm and its eradication from the root canal system are of utmost importance in the clinical practice of an endodontist. Various treatment strategies and protocols have been demonstrated and discussed by numerous clinicians and researchers, on these models, that play an important role in the treatment outcome . Once a biofilm model is developed by considering various factors, several methods can be used to assess the biofilms formed on these models. This review discusses the importance of biofilm models in endodontics, types of biofilm models and factors associated with developing and the methods to evaluate these models.
