The thought of minimally invasive endodontics principle has emerged to promote remedies that forestall the fracture of endodontically-treated teeth. One of the most fascinating subjects in minimally invasive endodontic remedy is the minimally invasive endodontic approaches. One such strategy is conservative endodontic cavities (CEC), first proposed through Clark and Khademi in 2010. CEC minimizes the elimination of enamel shape specifically so that the pericervical dentine (PCD) can be preserved [1]. The pericervical dentine is the dentine positioned in the four mm coronal and apical to the crestal bone. Some researchers have proven that pericervical dentine performs an essential biomechanical function, and its retention can enlarge the resistance of tooth to fracture. Therefore, a range of minimally invasive endodontic procedures have been developed with the motive of keeping extra dental tissue, mainly pericervical dentin, to forestall the fracture of teeth.
