Objective This study evaluated the effect of the supplementary use of the XP-endo Finisher on postoperative endodontic pain. Methods This study was a randomized clinical trial with a parallel design. Ninety-two posterior teeth with necrotic pulps and apical periodontitis were instrumented with a single file (Reciproc) in a reciprocating movement f...

This study evaluated the water content and sorption of direct composites over 60 days using coulometric Karl Fischer titration (KFT). Plate-shaped specimens (10 × 10 × 1 mm3 of thickness) were built up using the composites Clearfil Majesty Posterior (CM), Grandio SO (GS), and Filtek Supreme XT (FS). Water contents were determined in non-stored spec...

Aim To evaluate the influence of root canal filling quality on periapical lesion status using cone-beam computed tomography (CBCT). Materials and Methods The bibliographic search was conducted in electronic databases of PubMed, Embase, Scopus, and Web of Science without restrictions related to the year of publication and language. Inclusion criter...
Preprint
Objectives : This study evaluated the water content and sorption of direct composites over 60 days using coulometric Karl Fischer titration (KFT). Methods : Plate-shaped specimens (10 x 10 x 1 mm of thickness) were built up using the composites Clearfil Majesty Posterior (CM), Grandio SO (GS), and Filtek Supreme XT (FS). Water contents were determi...
Article
Aim : To evaluate in vitro the whiteness index (WID) and the whiteness index variation (ΔWID), as well as the color stability of stained endodontically treated teeth after bleaching with violet LED (VL) and with hydrogen peroxide 35% (HP) associated or not to VL. Methods : Twenty-four lower incisors were selected. The color was measured using a sp...
Article
Objectives This study aimed to evaluate the water content and uptake of CAD/CAM chairside composites over 60 days using coulometric Karl Fischer (KF) titration. Methods Rectangular plates (10 ×10×1 mm³ of thickness) were cut from the blocks of composites Cerasmart 270 (CS), Katana Avencia (KA), Grandio Blocs (GB), and Lava Ultimate (LU). Specimens...
Article
Purpose/Aim This study aimed to evaluate the water sorption of CAD/CAM chairside composites over 21 days using coulometric Karl-Fischer (KF) titration Materials and Methods Rectangular plates (10 ×10 x 1 mm of thickness) were cut from the blocks of composites Cerasmart 270 (CS), Katana Avencia Block (KA), Grandio Blocs (GB) and Lava Ultimate (LU)...
Article
The present study aimed to determine how spectrophotometer type and background blackness affect the optical evaluation of resin composites. Cylindrical specimens were built using one resin composite, provided with translucencies named Effect, Enamel, Body, and Dentin (n = 3). The CIELAB color coordinates were assessed over black and white backgroun...
Article

Objective This study aimed to evaluate the effect of interval time after acidic beverage intake and brushing on roughness and hardness of resin composite. Materials and Methods Nanofilled resin composites were tested as per interval time (no interval, 15 or 30 minutes) between aging media (isotonic, sports drink) and brushing. Specimens (n = 9) wer...
Article
Full-text available
Objectives: This systematic review evaluated the efficacy of the supplementary use of the XP-endo Finisher on bacteria content reduction in the root canal system. Materials and methods: In-vitro studies evaluating the use of the XP-endo Finisher on bacteria content were searched in four databases in July 2020. Two authors independently screened...
Article
Full-text available
Objectives: This study assessed the reliability of digital color measurements using images of resin composite specimens captured with a cellphone. Materials and methods: The reference color of cylindrical specimens built-up with the use of resin composite (shades A1, A2, A3, and A4) was measured with a portable spectrophotometer (CIELab). Images...
Article
Full-text available
This study investigated the effects of oxygen inhibition and finishing/polishing procedures on the composite resin properties. One bulk-fill and two conventional composite resins (nanoparticle and microhybrid) were evaluated. Specimens were prepared using 4 surface treatments: control, no treatment; Gly, oxygen inhibition with glycerin; FP, finishi...
Article
Full-text available
Objectives To compare the root filling quality, the sealer extrusion, and the healing rates of apical lesions addressed via two endodontic treatment approaches. The hypothesis tested was that both techniques present similar apical periodontitis healing results. Materials and methods This study was a parallel-design, pragmatic, and randomized clini...
Article
Aim To assess the impact of two canal treatment protocols on the oral health‐related quality of life (OHRQoL) of patients in need of root canal treatment on their anterior teeth. Methodology The sample consisted of 120 participants (mean age: 34 years old) enrolled in a pragmatic randomised clinical trial evaluating two root canal treatment protoc...
Article
Full-text available
This clinical trial evaluated the effect of preemptive use of the non-steroidal anti-inflammatory drug piroxicam in a single dose 30 min prior to in-office bleaching on the prevention of tooth sensitivity (TS) reported by patients. Fifty patients were submitted to two sessions of in-office tooth bleaching with 35% hydrogen peroxide used for 2 sessi...
Article
Objective To investigate the effect of filler content and the time spent before light-curing on mechanical properties of dual-cured cements. Methods Experimental dual-cured resin cements were formulated with 60, 65 or 68wt% of filler. The viscosity of experimental cements was measured using a digital viscometer. Bar-shaped specimens (25 x 2 x 2 mm...
Article
Background: In-office dental bleaching results in a high risk of tooth sensitivity caused by the inflammatory process of the pulpal tissue. In this systematic review, the authors aimed to evaluate the effect of administering anti-inflammatory and analgesic drugs for the prevention of tooth sensitivity associated with in-office dental bleaching. T...
Article
This in vitro study aimed to evaluate the effect of two alternative clinical protocols on the tooth bleaching effectiveness of 37% carbamide peroxide. Thirty enamel-dentin blocks from bovine incisors were stained with a coffee solution for 1 week. After color measurement at baseline with a portable spectrophotometer, the blocks were bleached during...
Article
Background: The present study evaluated the coronal discoloration induced by different materials or blood as well as the effect of internal bleaching on discoloration. Methods: After tooth color measurement at baseline with a sphere spectrophotometer (CIE L*a*b*), the root canals of molars were partially filled with white mineral trioxide aggreg...
