The purpose of this study was to evaluate the effect 2.5°C cold saline irrigation as final irrigant on postoperative pain after single-visit root canal treatment teeth with vital pulps. One-hundred and seventy patients were assessed eligible included study. randomly divided into two groups (n = 85) (i.e. control group cryotherapy group). In group, 0.9% physiological solution for 5 min performed following completion biomechanical preparation, whereas in same stored at temperature used....

Abstract Aim To compare the incidence, intensity and prediction of postoperative pain after glide path preparation with manual, continuous rotary a novel reciprocating instrument. Methodology The study included 240 patients, who were treated by four specialists according to planned treatment protocol. Following access cavity prior preparation, subjects randomly assigned one three groups instrument choosing sealed envelope containing group name: R‐Pilot ( VDW , Munich, Germany), ProGlider...

ABSTRACT This study tested the impact of troughing on detection rates MB2 canals with and without calcifications. Traditional access cavities were prepared was recorded in 200 maxillary molars selected based micro‐CT scans. In specimens, orifice not detected; performed. The number negotiated compared using McNemar's test. After traditional cavity preparation troughing, operator detected 142 specimens (82%). Troughing remaining led to further identification 16 canals, increasing rate 91%....

Abstract Aim This study aimed to evaluate the influence of virtual reality (VR) haptic simulators on manual dexterity, self‐confidence and stress levels 3rd‐semester dental students during preclinical endodontic training, as well determine optimal timing for their introduction into curriculum—before or after training with artificial teeth. Methodology Forty volunteered enrolled in were randomly divided two groups. Group 1 (VR Haptic Simulator group, n = 20) completed four sessions VR...

Instrument separation during root canal treatment can hinder effective cleaning and shaping, making reliable retrieval techniques essential. Endoscopic visualization might aid in instrument removal procedures offering direct magnification of anatomy. This ex vivo study evaluated the success rate procedure time three - Masserann, microsonic, loop under dental operation microscope (DOM) assisted by an endoscope. Sixty extracted human mandibular single-rooted teeth with simulated fractures were...

Abstract Aim To conduct a quantitative and qualitative analysis of the band‐shaped isthmus area, floor which was in apical third mesial roots mandibular first molars using micro‐computed tomography (micro‐CT). Methodology Micro‐CT images 269 were evaluated, 40 specimens with isthmus, third, selected. The major diameter, minor roundness, area perimeter values for most coronal slices where visible measured. distances between these measured as length, total volume, structure model index surface...

Abstract This study aims to compare the efficacy of different irrigation activation methods remove smear layer and debris from oval‐shaped root canals following retreatment. Ninety mandibular canines with were selected. Retreatment was performed R‐Endo retreatment files. The samples randomly divided into six groups ( n = 15). Groups assigned according agitation technique: classic irrigation, self‐adjustable file, passive ultrasonic R‐E ndo + E r: YAG , PIPS N d: . Compared CI ) group, all...

Objectives: The present study aimed to evaluate the shaping ability of 2 thermally treated nickel-titanium reciprocating systems in simulated curved canals.Materials and Methods: Forty canals were prepared apical size 25 using Reciproc Blue R25 (VDW) WaveOne Gold Primary (Dentsply Sirona) instruments.Standard pre-and post-preparation images taken superimposed.The removal resin material was measured at 5 standard points: canal orifice, halfway between orifice beginning curve, apex end-point...

To evaluate, using micro-CT, the remaining dentine thickness after preparation of mesiobuccal (MB), mesiolingual (ML) and middle mesial (MM) canals mandibular first molars with ProTaper Next rotary system.Eleven roots having three independent from furcation level up to at least 5 mm towards apical direction were selected. Preparation MM was performed in two steps X2 (step 1) X3 2) instruments, whilst MB ML prepared a single step instruments. The scanned (pixel size 10 µm) before each step,...

The present micro-computed tomography (micro-CT) study compared the presence of voids in band-shaped isthmuses obturated by warm vertical compaction (WVC) and single-cone (SC) techniques. Twenty mesial roots from mandibular first molar teeth showing a isthmus were selected assigned into two groups based on their preoperative anatomical dimensions (n = 10), according to filling technique: WVC or SC. Post-filling micro-CT scanning was performed. percentage volume root canal materials...

Background. The present study aimed to compare the shaping ability of Reciproc Blue instruments with or without creation a glide path in simulated S-shaped root canals. Methods. Root canals thirty #15.02 clear resin blocks were dyed using ink and photographed. Then randomly divided into 2 groups: group A: created ProGlider B: no preparation (n=15). also photographed after preparation. pre- post-prepara-tion images superimposed evaluated at 9 different measurement points according 3 zones, as...
