A thorough knowledge of root canal anatomy and its variation is necessary for successful completion of root canal procedures. Morphological variations such as additional root canals in human deciduous dentition are rare. A mandibular second primary molar with more than four canals is an interesting example of anatomic variations, especially when three of these canals are located in the distal root. This case shows a rare anatomic configuration and points out the importance of looking for additional canals.

Background: It is generally accepted that the greater palatine nerve and artery supply the palatal mucosa, gingiva, and glands, but not the bone or tooth adjacent to those tissues. When the bony palate is observed closely, multiple small foramina are seen on the palatal surface of the alveolar process. The authors hypothesized that the greater palatine nerve and artery might supply the maxillary teeth via the foramina on the palatal surface of the alveolar process and the superior alveolar nerve and artery.

Acceptability of interactive post-endodontic restoration decision making application among undergraduate dental students.

Background/purpose: Selecting an appropriate coronal restoration after root canal treatment requires careful consideration, however, there is a lack of established web-based tool that is based on clear guidelines for suitable post-endodontic restorations. Hence, we aimed to design and determine the acceptability of an interactive application to aid the decision making process for post-endodontic restoration among the undergraduate dental students.
Materials And Methods: A web-based post-endodontic restoration decision making interactive application, ( was developed after a detailed review of available literature.
Long-Term Success and Survival of Post-Endodontic Restorations Without Posts After up to18 Years: A Practice-Based Study.

Objectives: The aim of this non-interventional, multi-center, prospective, practice-based study was, firstly, to evaluate the longevity of composite build-ups in endodontically treated teeth, treated with root canal therapy (ETT), without post placement and secondly, to identify and analyze factors influencing the success of these reconstructions.
Methods: Each of seven general dental practitioners placed up to 50 composite build-ups without additional posts in ETT. Teeth were restricted to incisors, canines and premolars.
