Aim: To compare the effect of different tapers of the K3XF file system on the fracture resistance of endodontically treated mandibular premolars obturated with a three-dimensional (3-D) obturation system. Methodology: For the study, 80 freshly extracted human mandibular premolars with single well-developed roots without any curvatures were taken...

Dens invaginatus (DI) often causes dysmorphic changes in both the crown and root. This case report presents a complicated type 3a DI in a maxillary lateral incisor with labial talon cusp and root bifurcation. Although lingual talon cusp is common in maxillary lateral incisor, labial talon cusp is rare. An auxiliary palatal root in maxillary lateral...

We investigated the efficiency of Endosonic Blue, EDDY, Ultra X and EndoActivator in removing calcium hydroxide from artificially created apical grooves in root canal walls. In Materials and Methods: A total of 60 single-root maxillary central incisors, root canals were created and the roots were divided into two longitudinal parts. In the most sui...

Objective: This study aimed to evaluate the stationary fatigue resistance of three endodontic instrument systems after preparing three root canals with different curvatures and comparing them with unused instruments. Methods: A total of 60 endodontic files from 3 instrument systems, TruNatomy (TRN), HyFlex CM (HFC) and Revo-S (RS), were selected...

Objective: To compare the removal of calcium hydroxide (CaOH) pastes containing N-Methyl-2-pyrrolidone (NMP), lidocaine, glycerine, methylcellulose, or water from artificially created grooves. Methods: In this study, 115 human single-rooted maxillary incisors with single and straight root canals were prepared using a rotary file up to size 40/.0...

Aims: The study was aimed to evaluate and compare the compressive, diametral tensile, and flexural strengths of three different commercial resin based core materials and to single out the best resin-based core build-up material with respect to their physical properties among ParaCore® (Coltene Whaledent, USA), FlouroCore® 2+ (Dentsply Internationa...

Objectives: (1) To evaluate the effectiveness of the static-guided (SG) endodontics technique for accessing the root canal through the mineral trioxide aggregate (MTA) and (2) to evaluate the effect of this technique on the fracture strength of teeth. Materials and methods: Thirty mandibular premolars were used in the present study. After standa...

Aim: The purpose of this study was to evaluate the centering ability, canal transportation and efficacy of re-treatment rotary and hand files in removing Gutta Percha from root canals using Cone Beam Computed Tomography(CBCT). Materials and methods: Sixty extracted human maxillary anteriors were obturated and randomly divided into three groups....

Navigation of the main root canal and dealing with a dens invaginatus (DI) is a challenging task in clinical practice. Recently, the guided endodontics technique has become an alternative method for accessing root canals, surgical cavities, and calcified root canals without causing iatrogenic damage to tissue. In this case report, the use of the gu...

Dens invaginatus (DI) is one of the rare malformations of teeth which results from an infolding of the dental papilla during the development of teeth. This defect gives rise to a possible communication between the pulp and oral environment, thereby increasing the susceptibility to caries, pulpitis, and pulp necrosis. Thus, early detection and conse...

Background: To investigate the efficiency of Hedstrom (H; Dentsply Maillefer) file, Protaper Universal Retreatment system (PTUR; Dentsply Maillefer), Mani NRT-GPR files (Mani, Japan) and WaveOne (WO; Dentsply Maillefer) Reciprocating files in removing Gutta Percha (GP) and sealer from root canals. Methods: Sixty canals with less than 10° curvature...

Dens invaginatus (DI) is an unusual anomaly of teeth, presumably resulting from an infolding of the dental papilla during tooth development. The root canal treatment of such teeth is arduous because of problems associated with gaining access to the root canals and with variations of canal morphology associated with this type of malformation. The pr...

Abstract The rapidly evolving implantation and alveolar ridge reconstruction techniques opened a new era in modern dentistry, where tooth loss is no longer a problem. However, none of the modern technologies in implant dentistry have the potential to adapt to the growth and development changes of a child’s jaw. Therefore, patients at young ages app...
