Perforations are the most common and frequent errors that occur during endodontic therapy, especially, in calcified canals and curved canals that affect the prognosis of the affected tooth. The diagnosis of dental pulp and/or periapical tissue previous to root perforation is an important predictor of prognosis along with location and size of exposure. Recently, new materials have been introduced for further improving the chances of a successful outcome when accompanied with the experience and expertise of the practitioner.

Digital technologies are disrupting dentistry at an unprecedented pace. This technological revolution is changing the landscape of the dental profession in terms of the treatments available, the training needed to perform those treatments, and the jobs involved in conducting the treatments. It is very likely that eventually all dental restorative procedures will be performed using digital technologies. This will simplify the clinical procedures and the training needed to do them while improving treatment outcomes and reducing costs.

Successful root canal therapy depends on thorough debridement of pulpal tissue, dentin debris and infective microorganisms. Currently, it is impossible to predictably eradicate intraradicular infection with mechanical instrumentation alone. Therefore, irrigants are required to be used as an important addition in the disinfection process. Elimination of organic tissue and reduction of the microbial bio-burden remain a difficult task, especially in the apical-third of the root canal system because of anatomical irregularities. Microorganisms residing in these complex areas may flourish if they...

The endodontic management of a fractured instrument or any metallic object within the root canal is a sophisticated process that requires training, experience, and knowledge of the techniques that can be used. It is a time consuming and challenging procedure often associated with anxiety for both clinician and patient with variable success rate. Many factors must be considered before attempting to manage the instrument fragment.The prime therapeutic option for the management of instrument fracture is non-surgical aiming in the retrieval of the fragment. If this attempt fails, bypassing is the...
