This study aimed to compare the effect of different pressures of air particle abrasion 2 and 4 bars before and after sintering with and without zirconia liner on SBS of resin to zirconia Surface. Materials and Methods: 54 zirconia cuboids 8×8×3 mm were milled and divided into 6 equal groups (N=9) according to surface treatment; sintered with ceramic liner application and 2 bars pressure (SL2) and with 4 bars pressure (SL4), sintered with no ceramic liner and 2 bars pressure (SN2) and 4 bars pressure (SN4), unsintered with no ceramic liner and 2 bars pressure (UN2) and 4 bars pressure …

The root-end resection is considered critical endodontic surgical procedure. Three millimeters of the root tip is resected and root-end cavity with parallel walls and comparable depth is cut to receive a root-end filling. The literature discussed dentinal cracks after root canal instrumentation and/or root dentine cutting. The aim of the present study was to assess cracks at root ends after resection with conventional versus ultrasonic techniques. Material and Methodology: Thirty-two extracted human lower premolar teeth with single root were used. Their root canals were prepared and received gutta-percha. Sixteen roots Group 1 were resected using tungsten carbide fissure burs, while …

Enterococcus faecalis is the most common bacteria isolated in conventional endodontic retreatments. Aim: To compare the impact of three irrigation modalities on the elimination of the isolated microbial strains of Enterococcus faecalis. Materials and Methods: Thirty patients requiring conventional endodontic retreatment for one of their mandibular premolars and tested positive for E. faecalis were chosen. Patients were randomly divided into three groups (n=10) according to the irrigation modality to be used; group I: syringe irrigation (NaOCl 2.625%), group II: NaOCl 2.625%+EndoActivator and group III: NaOCl 2.625%+diode laser. Before obturation, samples S2 were collected and PCR analysis was performed to identify …

The ongoing advancement of materials and methods for root canal instrumentation is resulting in improved techniques with minimal variations to the canal morphology. One standard for assessment of the shaping quality of curved root canals is preparation-induced straightening of the canal. The aim of the study: To compare the effects of 2 Nickel-Titanium rotary systems, 2Shape (Micro-Mega, Besançon, France) and ProTaper Next (Dentsply,Sirona, Ballaigues, Switzerland), on maintaining the distobuccal canals curvature of extracted human maxillary molar teeth using periapical radiographs. Materials and methods: In this study a total of 26 distobuccal roots of upper maxillary molars were used and divided …
