Non-carious Cervical Lesion: A Review Article.

Non-carious cervical lesions are usually described as “tooth substance loss.” Such process includes attrition, abrasion, erosion, abfraction, localized non-hereditary dentinal hypocalcification, localized non-hereditary dentinal hypoplasia, amelogenesis imperfecta, dentinogenesis imperfecta, and tooth trauma. The non-carious cervical lesion is complex lesions in which there is a loss of enamel, dentin, cementum, bone and keratinized attached gingiva. Furthermore, there is gingival crest disharmony, poor emergence profile, loss of identifiable cemento-enamel junction, Miller’s recession class, and dentin/root sensitivity. The treatment of this non-carious lesion includes restorations such as glass-ionomer cement (GIC), composites, and Resin-modified GIC. We can even restore them with porcelain fused metal crowns or full ceramic crowns.

Presence of Mesiobuccal 2 and Mesiobuccal 3 Canal in Maxillary First Molar: An Illusion.

Successful endodontic treatment involves a proper access cavity preparation, biomechanical principles, and three-dimensional obturation. Thus, the clinician should have a through knowledge of anatomy and morphology of the root canal system. Failure in root canal therapy may be due to inability in locating the canal and its proper debridement. The configuration and a number of root canals in the maxillary first molars have been discussed for more than half a century. Maxillary first molars commonly present with three roots and three canals, with a second mesiobuccal canal (MB2) and (MB3). The current case reports describe the presence of extra canals MB2 and MB3 in a maxillary first molar.

You Can Never Judge the Fate of a Broken Tip in Endodontic Practice.

The fracture of endodontic instruments is a common procedural error created during a root canal therapy. Starting from the hand files and up to the use of rotary systems, the root canal therapy is sometimes associated with the fracture of the instruments inside the root canal. The purpose of this work was to report a clinical case of removal of a fractured endodontic instrument in the root canal of a maxillary premolar, when part of this fragment extended through the apical foramen. In this case, a simple and a feasible chairside technique was used for the retrieval of the separated file tip.
