One of the main causes of endodontic treatment failure is the clinician's inability to localize all the root canals. Due to the complex anatomy of the root canal system, missed canals are not uncommon. There are several strategies to decrease the possibility of missed root canals starting with good pre-operative radiographies. In order to overcome the limitations of conventional radiographies, ...

It is generally accepted that a major cause of the failure of root canal therapy is an inability to localize and treat all of the canals of the root canal system. The risk of missing anatomy during root canal treatment is high because of the complexity of the root canal system. All categories of teeth may have extra roots and/or canals, but the likelihood of finding aberrant canal configuration...

Endodontic therapy aims at disinfection of the root canal system. Efforts are made by instrumentation and chemical to remove infected pulp tissue debris from space. However due variations in anatomy, it is impossible instrument all parts that may lead persistence or progression infection. Thorough knowledge tooth morphology important improve success rate endodontic treatment. Missed canals cons...

Endodontic treatment failure can be caused by a variety of factors, including bacterial persistence, improperly cleaned and obturated root canals, faulty coronal seal (leakage), untreated canals (missed canals). The presence bacteria such as Enterococcus (E.) faecalis inside the canal system is most common cause endodontic failure. These are more resistant to disinfectants, resulting in an infe...

Maxillary first premolar is most commonly a bi-rooted tooth, occasionally having three roots. It usually has two canals, but may rarely have three, which can easily be missed, demanding more attention during endodontic intervention. This paper reports this rarity of 3 roots and canals in maxillary premolar, highlighting the difficulties special care needed treatment. Careful investigation diagn...

The maxillary first premolar is the most commonly bi- rooted tooth with occasional presentation of three roots system; it is a transitional tooth between incisors and molars. Although it usually has two canals, it may rarely have three and this third canal can easily be missed. Thus meticulous knowledge of tooth morphology, careful interpretation of angled radiographs, proper access cavity prep...

Successful Endodontic treatment depends upon Adequate knowledge about the morphology of root canal system and diagnosing the anatomic variants to avoid missed canals. Maxillary second molars usually present with two buccal and one palatal root. Occurrence of an extra palatal root is a rare scenario with prevalence of around 1.4%.. The following case report describes endodontic management of max...
