this case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. in all represented cases, calcium enriched mixture (cem) cement is used for root-end filling. this case series demonstrates twenty cases of ir and extraoral root-end resection and filling with cem cement. all the selected teeth had a failed endodontic tr...

introduction: apical transportation changes the physical shape and physiologic environment of the root canal terminus. the aim of the present experimental study was to determine the extent of apical transportation after instrumentation with hand k-flexofile and k3 rotary instruments by means of cone-beam computed tomography (cbct). methods and materials: forty mesiobuccal root canals of maxilla...

INTRODUCTION Coronal anatomic variations in permanent maxillary molars are unusual; conversely variations involving the number of root canals or number of roots are more common. METHODS AND MATERIALS This case report presents a successful nonsurgical endodontic therapy of left maxillary first molar with three roots and seven root canals. This unusual morphology was diagnosed using a dental op...

Background. The retromolar canal (RMC) is an anatomical variation that can cause complications in dental procedures. Method. The RMC was evaluated according to age, sex, and presence of accessory mandibular canal and accessory mental foramen, on both sides in 500 panoramic radiographs, belonging to individuals at the age of 7 to 20 years. The associations of interest were studied through Fisher...

Dens invaginatus is a malformation of teeth probably resulting from an infolding of the dental papilla during tooth development. Affected teeth show a deep infolding of enamel and dentine starting from the foramen coecum or even the tip of the cusps, and which may extend deep into the root. Teeth most affected are maxillary lateral incisors and bilateral occurrence is not uncommon. The malforma...

Coronal restorations and posts can positively influence the long-term prognosis of teeth following root canal therapy. Final sealing the canal by placing an appropriate post and core will minimize leakage of oral fluids and bacteria into the periradicular area and is recommended as soon as possible after completion of root canal filling. Glass ionomer or MTA placed over the residual root canal ...

INTRODUCTION The fracture strength of endodontically treated teeth compared to vital ones has long been a source of controversy. It is not clear how root canal therapy affects the stress distribution in teeth. The purpose of this study was to evaluate the changes in stress distribution after root canal therapy in a human maxillary canine by finite element analysis (FEM). MATERIALS AND METHODS...

Irrigation has been performed in conjunction with endodontic therapy for many years. One of the primary reasons for irrigating the root canal system is to ensure cleanliness of the canals prior to obturation. This cleanliness involves both elimination of microorganisms and removal of organic matter. Sodium hypochlorite [NaOCl] is the most commonly used solution in root canal treatments, despite...
